Title
smb: client: reject userspace cifs.spnego descriptions
Summary
In the Linux kernel, the following vulnerability has been resolved:
smb: client: reject userspace cifs.spnego descriptions
cifs.spnego key descriptions contain authority-bearing fields such as
pid, uid, creduid, and upcall_target that cifs.upcall treats as
kernel-originating inputs. However, userspace can also create keys of
this type through request_key(2) or add_key(2), allowing those fields to
be supplied without CIFS origin.
Only accept cifs.spnego descriptions while CIFS is using its private
spnego_cred to request the key.

Threats
Impact
Important
A flaw was found in the Linux kernel's traffic control packet editing (pedit) subsystem. In tcf_pedit_act(), the copy-on-write (COW) range for skb_ensure_writable() is computed once before iterating over edit keys, but the calculation does not account for runtime header offsets added by typed keys. This can leave part of the target write region without a proper copy-on-write, leading to an out-of-bounds write that corrupts page cache memory. A local attacker with the ability to configure traffic control rules could exploit this to escalate privileges or crash the system.

"text": "This issue is classified as Important severity primarily because a low-privileged local user can achieve full privilege escalation to root without any user interaction. The attack requires local access, which prevents remote exploitation and is the primary factor keeping the rating at Important rather than Critical.\n\nExploitation requires three components to be present on the system: the `cifs` kernel module (loaded or loadable), the `cifs-utils` package with its default `cifs.spnego` request-key rule, and the ability to create unprivileged user and mount namespaces. All three must be present for the attack chain to succeed. Environments that do not use SMB/CIFS file shares or Active Directory integration are unlikely to have `cifs-utils` installed, reducing their exposure.\n\nIn OpenShift Container Platform 4, this flaw is rated Low. The default `restricted-v2` Security Context Constraint (SCC) sets `allowPrivilegeEscalation: false` on all pods, which causes the kernel to ignore setuid file bits, preventing privilege escalation. Under non-default SCCs such as `anyuid` that permit privilege escalation, the vulnerability is constrained by PID and mount namespace isolation to the container\u0027s own filesystem. An attacker would only be able to escalate privileges within the container, not on the host or across pods.",

"text": "A flaw was found in the Linux kernel\u0027s traffic control packet editing (pedit) subsystem. In tcf_pedit_act(), the copy-on-write (COW) range for skb_ensure_writable() is computed once before iterating over edit keys, but the calculation does not account for runtime header offsets added by typed keys. This can leave part of the target write region without a proper copy-on-write, leading to an out-of-bounds write that corrupts page cache memory. A local attacker with the ability to configure traffic control rules could exploit this to escalate privileges or crash the system.",

By default in Red Hat Enterprise Linux, this limits exploitation to the root user or processes explicitly granted network administration capabilities. However, in some circumstances unprivileged users may obtain CAP_NET_ADMIN within user namespaces. Successful exploitation could lead to arbitrary code execution in kernel context or a system crash.\n\nRed Hat Enterprise Linux 7 and earlier are not affected. Within OpenShift Container Platform, the vulnerable module is not loaded by default, reducing the severity to Low.",

Threats
Impact
Important
A flaw was found in the Linux kernel's traffic control packet editing (pedit) subsystem. In tcf_pedit_act(), the copy-on-write (COW) range for skb_ensure_writable() is computed once before iterating over edit keys, but the calculation does not account for runtime header offsets added by typed keys. This can leave part of the target write region without a proper copy-on-write, leading to an out-of-bounds write that corrupts page cache memory. A local attacker with the ability to configure traffic control rules could exploit this to escalate privileges or crash the system.

"text": "This issue is classified as Important severity primarily because a low-privileged local user can achieve full privilege escalation to root without any user interaction. The attack requires local access, which prevents remote exploitation and is the primary factor keeping the rating at Important rather than Critical.\n\nExploitation requires three components to be present on the system: the `cifs` kernel module (loaded or loadable), the `cifs-utils` package with its default `cifs.spnego` request-key rule, and the ability to create unprivileged user and mount namespaces. All three must be present for the attack chain to succeed. Environments that do not use SMB/CIFS file shares or Active Directory integration are unlikely to have `cifs-utils` installed, reducing their exposure.\n\nIn OpenShift Container Platform 4, this flaw is rated Low. The default `restricted-v2` Security Context Constraint (SCC) sets `allowPrivilegeEscalation: false` on all pods, which causes the kernel to ignore setuid file bits, preventing privilege escalation. Under non-default SCCs such as `anyuid` that permit privilege escalation, the vulnerability is constrained by PID and mount namespace isolation to the container\u0027s own filesystem. An attacker would only be able to escalate privileges within the container, not on the host or across pods.",

"text": "A flaw was found in the Linux kernel\u0027s traffic control packet editing (pedit) subsystem. In tcf_pedit_act(), the copy-on-write (COW) range for skb_ensure_writable() is computed once before iterating over edit keys, but the calculation does not account for runtime header offsets added by typed keys. This can leave part of the target write region without a proper copy-on-write, leading to an out-of-bounds write that corrupts page cache memory. A local attacker with the ability to configure traffic control rules could exploit this to escalate privileges or crash the system.",

"text": "Red Hat rates this flaw as Important severity.\n\nThis vulnerability is in the kernel\u0027s traffic control (tc) pedit action, which requires CAP_NET_ADMIN capability to configure. By default in Red Hat Enterprise Linux, this limits exploitation to the root user or processes explicitly granted network administration capabilities. However, in some circumstances unprivileged users may obtain CAP_NET_ADMIN within user namespaces. Successful exploitation could lead to arbitrary code execution in kernel context or a system crash.\n\nRed Hat Enterprise Linux 7 and earlier are not affected. Within OpenShift Container Platform, the vulnerable module is not loaded by default, reducing the severity to Low.",

Threats
Impact
Important
A flaw was found in the Linux kernel's traffic control packet editing (pedit) subsystem. In tcf_pedit_act(), the copy-on-write (COW) range for skb_ensure_writable() is computed once before iterating over edit keys, but the calculation does not account for runtime header offsets added by typed keys. This can leave part of the target write region without a proper copy-on-write, leading to an out-of-bounds write that corrupts page cache memory. A local attacker with the ability to configure traffic control rules could exploit this to escalate privileges or crash the system.

"text": "This issue is classified as Important severity primarily because a low-privileged local user can achieve full privilege escalation to root without any user interaction. The attack requires local access, which prevents remote exploitation and is the primary factor keeping the rating at Important rather than Critical.\n\nExploitation requires three components to be present on the system: the `cifs` kernel module (loaded or loadable), the `cifs-utils` package with its default `cifs.spnego` request-key rule, and the ability to create unprivileged user and mount namespaces. All three must be present for the attack chain to succeed. Environments that do not use SMB/CIFS file shares or Active Directory integration are unlikely to have `cifs-utils` installed, reducing their exposure.\n\nIn OpenShift Container Platform 4, this flaw is rated Low. The default `restricted-v2` Security Context Constraint (SCC) sets `allowPrivilegeEscalation: false` on all pods, which causes the kernel to ignore setuid file bits, preventing privilege escalation. Under non-default SCCs such as `anyuid` that permit privilege escalation, the vulnerability is constrained by PID and mount namespace isolation to the container\u0027s own filesystem. An attacker would only be able to escalate privileges within the container, not on the host or across pods.",

Threats
Impact
Important
A flaw was found in the Linux kernel's traffic control packet editing (pedit) subsystem. In tcf_pedit_act(), the copy-on-write (COW) range for skb_ensure_writable() is computed once before iterating over edit keys, but the calculation does not account for runtime header offsets added by typed keys. This can leave part of the target write region without a proper copy-on-write, leading to an out-of-bounds write that corrupts page cache memory. A local attacker with the ability to configure traffic control rules could exploit this to escalate privileges or crash the system.

"text": "This issue is classified as Important severity primarily because a low-privileged local user can achieve full privilege escalation to root without any user interaction. The attack requires local access, which prevents remote exploitation and is the primary factor keeping the rating at Important rather than Critical.\n\nExploitation requires three components to be present on the system: the `cifs` kernel module (loaded or loadable), the `cifs-utils` package with its default `cifs.spnego` request-key rule, and the ability to create unprivileged user and mount namespaces. All three must be present for the attack chain to succeed. Environments that do not use SMB/CIFS file shares or Active Directory integration are unlikely to have `cifs-utils` installed, reducing their exposure.\n\nIn OpenShift Container Platform 4, this flaw is rated Low. The default `restricted-v2` Security Context Constraint (SCC) sets `allowPrivilegeEscalation: false` on all pods, which causes the kernel to ignore setuid file bits, preventing privilege escalation. Under non-default SCCs such as `anyuid` that permit privilege escalation, the vulnerability is constrained by PID and mount namespace isolation to the container\u0027s own filesystem. An attacker would only be able to escalate privileges within the container, not on the host or across pods.",

Threats
Exploit Status
CISA: https://www.cisa.gov/known-exploited-vulnerabilities-catalog
Impact
Important
A flaw was found in the Linux kernel's IPv6 tunnel implementation. A remote attacker could exploit this flaw by sending malicious ICMPv6 error messages to cause a stack-based buffer overflow in the kernel's IPv4-over-IPv6 tunnel error handling code. This could result in a kernel crash (denial of service) or potentially allow arbitrary code execution with kernel privileges.

Threats
Impact
Critical
A flaw was found in the Linux kernel's xfrm-ESP and RxRPC subsystems. Unsafe in-place cryptographic processing of shared socket buffer fragments allows a low-privileged local attacker to corrupt page-cache contents of readable files, including sensitive system files, and gain root privileges. The xfrm-ESP variant requires unprivileged user or network namespace creation, while the RxRPC variant depends on the rxrpc module being available on the target system.

Threats
Impact
Important
A flaw was found in the Linux kernel's networking (skbuff) component. When skb_try_coalesce() attaches paged fragments, it can lose the SKBFL_SHARED_FRAG marker. This can lead to the Encapsulating Security Payload (ESP) input decrypting data in place over page-cache backed fragments, potentially resulting in data corruption.

Threats
Impact
Important
A flaw was found in the Linux kernel's XFRM ESP-in-TCP subsystem. Unsafe in-place cryptographic processing allows a low-privileged local attacker to write arbitrary bytes into the page cache of read-only files, including sensitive system files. An attacker can exploit this to overwrite privileged binaries and gain root privileges.

Threats
Impact
Important
A vulnerability was found in the Linux kernel that allows an unprivileged local user to read sensitive files normally restricted to the root user. The flaw occurs during process exit, where a brief window allows an attacker to intercept file access from a privileged process before it fully terminates. Successful exploitation may lead to the disclosure of sensitive data such as SSH host private keys or /etc/shadow contents.

"text": "This issue is classified as Important severity primarily because a low-privileged local user can achieve full privilege escalation to root without any user interaction. The attack requires local access, which prevents remote exploitation and is the primary factor keeping the rating at Important rather than Critical.\n\nExploitation requires three components to be present on the system: the `cifs` kernel module (loaded or loadable), the `cifs-utils` package with its default `cifs.spnego` request-key rule, and the ability to create unprivileged user and mount namespaces. All three must be present for the attack chain to succeed. Environments that do not use SMB/CIFS file shares or Active Directory integration are unlikely to have `cifs-utils` installed, reducing their exposure.\n\nIn OpenShift Container Platform 4, this flaw is rated Low. The default `restricted-v2` Security Context Constraint (SCC) sets `allowPrivilegeEscalation: false` on all pods, which causes the kernel to ignore setuid file bits, preventing privilege escalation. Under non-default SCCs such as `anyuid` that permit privilege escalation, the vulnerability is constrained by PID and mount namespace isolation to the container\u0027s own filesystem. An attacker would only be able to escalate privileges within the container, not on the host or across pods.",

"text": "This is an Important flaw in the Linux kernel that allows a local unprivileged attacker to read root-owned files. The vulnerability arises from a race condition during process termination, enabling a brief window where sensitive data, such as SSH host private keys or /etc/shadow contents, can be disclosed. This could lead to unauthorized access to sensitive information on affected Red Hat Enterprise Linux systems.\n\nIn OpenShift Container Platform 4, this flaw is rated Low. The default `restricted-v2` Security Context Constraint (SCC) sets `allowPrivilegeEscalation: false` on all pods, which causes the kernel to ignore setuid file bits and prevents target binaries from opening privileged files, breaking the exploit chain entirely. Under non-default SCCs such as `anyuid` that permit privilege escalation, the vulnerability is constrained by PID and mount namespace isolation to the container\u0027s own filesystem. An attacker would only be able to access root-owned files already within the container, not host or cross-pod resources. In practice, containers rarely contain sensitive root-owned files that are not already accessible to the pod user through normal means.",

Threats
Impact
Important
A privilege escalation vulnerability was found in the Linux kernel's CIFS client implementation. This could allow a local attacker to impersonate other users, bypass authentication in SMB mount operations, and potentially gain unauthorized access to network file shares or escalate privileges.

Threats
Impact
Low
A flaw was found in the Linux kernel's traffic control packet editing (pedit) subsystem. In tcf_pedit_act(), the copy-on-write (COW) range for skb_ensure_writable() is computed once before iterating over edit keys, but the calculation does not account for runtime header offsets added by typed keys. This can leave part of the target write region without a proper copy-on-write, leading to an out-of-bounds write that corrupts page cache memory. A local attacker with the ability to configure traffic control rules could exploit this to escalate privileges or crash the system.

"text": "This issue is classified as Important severity primarily because a low-privileged local user can achieve full privilege escalation to root without any user interaction. The attack requires local access, which prevents remote exploitation and is the primary factor keeping the rating at Important rather than Critical.\n\nExploitation requires three components to be present on the system: the `cifs` kernel module (loaded or loadable), the `cifs-utils` package with its default `cifs.spnego` request-key rule, and the ability to create unprivileged user and mount namespaces. All three must be present for the attack chain to succeed. Environments that do not use SMB/CIFS file shares or Active Directory integration are unlikely to have `cifs-utils` installed, reducing their exposure.\n\nIn OpenShift Container Platform 4, this flaw is rated Low. The default `restricted-v2` Security Context Constraint (SCC) sets `allowPrivilegeEscalation: false` on all pods, which causes the kernel to ignore setuid file bits, preventing privilege escalation. Under non-default SCCs such as `anyuid` that permit privilege escalation, the vulnerability is constrained by PID and mount namespace isolation to the container\u0027s own filesystem. An attacker would only be able to escalate privileges within the container, not on the host or across pods.",

A flaw was found in crun, an open-source OCI Container Runtime. A local user can exploit this vulnerability due to incorrect parsing of the `--user` option when using `crun exec`. The value `1` is misinterpreted as root privileges (User ID 0 and Group ID 0) instead of the intended User ID 1 and Group ID 0. This allows a process to run with higher privileges than expected, leading to privilege escalation.

Environments that do not use SMB/CIFS file shares or Active Directory integration are unlikely to have `cifs-utils` installed, reducing their exposure.\n\nIn OpenShift Container Platform 4, this flaw is rated Low. The default `restricted-v2` Security Context Constraint (SCC) sets `allowPrivilegeEscalation: false` on all pods, which causes the kernel to ignore setuid file bits, preventing privilege escalation. Under non-default SCCs such as `anyuid` that permit privilege escalation, the vulnerability is constrained by PID and mount namespace isolation to the container\u0027s own filesystem. An attacker would only be able to escalate privileges within the container, not on the host or across pods.",

A flaw was found in gnutls. A remote attacker could exploit an issue in the Datagram Transport Layer Security (DTLS) packet reordering logic. The comparator function, responsible for ordering DTLS packets by sequence numbers, did not correctly handle packets with duplicate sequence numbers. This could lead to unstable packet ordering or undefined behavior, resulting in a denial of service.

Threats
Impact
Important
A flaw was found in gnutls. Servers configured with RSA-PSK (Rivest–Shamir–Adleman – Pre-Shared Key) wrongfully matched usernames containing a NUL character with truncated usernames. A remote attacker could exploit this by sending a specially crafted username, leading to an authentication bypass. This vulnerability allows an attacker to gain unauthorized access by circumventing the authentication process.

"text": "This issue is classified as Important severity primarily because a low-privileged local user can achieve full privilege escalation to root without any user interaction. The attack requires local access, which prevents remote exploitation and is the primary factor keeping the rating at Important rather than Critical.\n\nExploitation requires three components to be present on the system: the `cifs` kernel module (loaded or loadable), the `cifs-utils` package with its default `cifs.spnego` request-key rule, and the ability to create unprivileged user and mount namespaces. All three must be present for the attack chain to succeed. Environments that do not use SMB/CIFS file shares or Active Directory integration are unlikely to have `cifs-utils` installed, reducing their exposure.\n\nIn OpenShift Container Platform 4, this flaw is rated Low. The default `restricted-v2` Security Context Constraint (SCC) sets `allowPrivilegeEscalation: false` on all pods, which causes the kernel to ignore setuid file bits, preventing privilege escalation. Under non-default SCCs such as `anyuid` that permit privilege escalation, the vulnerability is constrained by PID and mount namespace isolation to the container\u0027s own filesystem. An attacker would only be able to escalate privileges within the container, not on the host or across pods.",

A flaw was found in gnutls. A remote attacker could exploit an issue in the Datagram Transport Layer Security (DTLS) packet reordering logic. The comparator function, responsible for ordering DTLS packets by sequence numbers, did not correctly handle packets with duplicate sequence numbers. This could lead to unstable packet ordering or undefined behavior, resulting in a denial of service.

Threats
Impact
Important
A flaw was found in gnutls. Servers configured with RSA-PSK (Rivest–Shamir–Adleman – Pre-Shared Key) wrongfully matched usernames containing a NUL character with truncated usernames. A remote attacker could exploit this by sending a specially crafted username, leading to an authentication bypass. This vulnerability allows an attacker to gain unauthorized access by circumventing the authentication process.

"text": "This issue is classified as Important severity primarily because a low-privileged local user can achieve full privilege escalation to root without any user interaction. The attack requires local access, which prevents remote exploitation and is the primary factor keeping the rating at Important rather than Critical.\n\nExploitation requires three components to be present on the system: the `cifs` kernel module (loaded or loadable), the `cifs-utils` package with its default `cifs.spnego` request-key rule, and the ability to create unprivileged user and mount namespaces. All three must be present for the attack chain to succeed. Environments that do not use SMB/CIFS file shares or Active Directory integration are unlikely to have `cifs-utils` installed, reducing their exposure.\n\nIn OpenShift Container Platform 4, this flaw is rated Low. The default `restricted-v2` Security Context Constraint (SCC) sets `allowPrivilegeEscalation: false` on all pods, which causes the kernel to ignore setuid file bits, preventing privilege escalation. Under non-default SCCs such as `anyuid` that permit privilege escalation, the vulnerability is constrained by PID and mount namespace isolation to the container\u0027s own filesystem. An attacker would only be able to escalate privileges within the container, not on the host or across pods.",

"text": "This issue is classified as Important severity primarily because a low-privileged local user can achieve full privilege escalation to root without any user interaction. The attack requires local access, which prevents remote exploitation and is the primary factor keeping the rating at Important rather than Critical.\n\nExploitation requires three components to be present on the system: the `cifs` kernel module (loaded or loadable), the `cifs-utils` package with its default `cifs.spnego` request-key rule, and the ability to create unprivileged user and mount namespaces. All three must be present for the attack chain to succeed. Environments that do not use SMB/CIFS file shares or Active Directory integration are unlikely to have `cifs-utils` installed, reducing their exposure.\n\nIn OpenShift Container Platform 4, this flaw is rated Low. The default `restricted-v2` Security Context Constraint (SCC) sets `allowPrivilegeEscalation: false` on all pods, which causes the kernel to ignore setuid file bits, preventing privilege escalation. Under non-default SCCs such as `anyuid` that permit privilege escalation, the vulnerability is constrained by PID and mount namespace isolation to the container\u0027s own filesystem. An attacker would only be able to escalate privileges within the container, not on the host or across pods.",
