A flaw was found in OpenSSL's Cryptographic Message Services (CMS) AuthEnvelopedData processing. An on-path attacker can exploit insufficient input validation on cipher and tag length fields by sending specially crafted CMS messages. This can lead to the forging of messages or bypassing integrity validation. Consequently, an attacker may achieve key-equivalent functionality for a given CMS recipient.

Threats
Impact
Moderate
A flaw was found in the Linux kernel's netfilter component, specifically within the `nft_set_pipapo_avx2` AVX2 matching functions. This vulnerability occurs when a `pipapo` set with an 'ipv4 . port' key is reloaded. Due to incorrect masking, the system may erroneously identify non-matching elements as duplicates, leading to data integrity issues and unexpected behavior. A remote attacker could potentially exploit this to cause a denial of service or impact data integrity.
8.1 (High)
Affected products
Fixed
4 products, the same list as for
CVE-2026-34182
Threats
Impact
Important
A flaw was found in OpenSSL. Applications that use the AES-OCB encryption method with a specific one-shot interface (EVP_Cipher()) will have their provided Initialization Vector (IV) silently discarded. This leads to the same internal cryptographic value being used repeatedly, which compromises the confidentiality of encrypted data. Additionally, this issue allows for the universal forgery of authentication tags, undermining the integrity of communications.
9.1 (Critical)
Affected products
Fixed
4 products, the same list as for
CVE-2026-34182
Threats
Impact
Moderate
A flaw was found in the `acl` package, specifically within its `libacl` pathname-based functions. A local attacker could exploit this vulnerability by using a symbolic link to replace a pathname component. This could allow the attacker to redirect access control list (ACL) read or write operations to arbitrary files or directories, leading to unauthorized manipulation of ACLs and ultimately local privilege escalation.
7.1 (High)
Affected products
Fixed
4 products, the same list as for
CVE-2026-34182

Impact
Important
A flaw was found in GLib. An off-by-one error can occur in the g_key_file_get_locale_string_list function in the gkeyfile.c file when loading a key file with an empty value. This flaw can cause an out-of-bounds access of 1 byte or a denial of service when the out-of-bounds access crosses a page boundary.
7.3 (High)
Affected products
Fixed
4 products, the same list as for
CVE-2026-34182
Threats
Impact
Moderate
A flaw was found in OpenSSH. The `sftp` client, when used to download files from a malicious server with the 'sftp server:/path .' command, does not properly restrict where those files are saved. This allows an attacker to control the download location, potentially overwriting existing files or placing malicious files in sensitive directories on the client system, which could compromise system integrity.
5.4 (Medium)
Affected products
Fixed
4 products, the same list as for
CVE-2026-34182
Threats
Impact
Moderate
A flaw was found in `sshd`, the OpenSSH server daemon. When `DisableForwarding=yes` is configured to prevent network traffic forwarding, it incorrectly fails to take precedence over `PermitTunnel=yes`. This allows a remote attacker to bypass intended security restrictions and establish a tunnel, potentially leading to unauthorized network access or circumvention of security policies, even when forwarding is explicitly disabled.
7.5 (High)
Affected products
Fixed
4 products, the same list as for
CVE-2026-34182
Threats
Impact
Important
A flaw was found in OpenSSH. A remote attacker could exploit a use-after-free vulnerability on the client side when a server changes its host key during a key re-exchange. This could lead to high impact on confidentiality and integrity, and low impact on availability.
7.7 (High)
Affected products
Fixed
4 products, the same list as for
CVE-2026-34182
Threats
Impact
Important
A flaw was found in the Stream Control Transmission Protocol (SCTP) implementation within the Linux kernel. A remote attacker could send a specially crafted sequence of ASCONF (Add IP Address Configuration) chunks, including DEL-IP (Delete IP Address) parameters, to trigger a use-after-free condition. This memory corruption could lead to a system crash, resulting in a denial of service, and potentially allow for arbitrary code execution.
7.8 (High)
Affected products
Fixed
4 products, the same list as for
CVE-2026-34182
Threats
Impact
Important
A flaw was found in the Linux kernel's PPPoE (Point-to-Point Protocol over Ethernet) implementation. This vulnerability occurs because a pointer to network packet data is not updated after memory is reallocated, leading to the use of an outdated memory address. An attacker with local access could potentially trigger this condition, causing memory corruption. This could result in a system crash (denial of service) or other unpredictable system behavior.
7.3 (High)
Affected products
Fixed
4 products, the same list as for
CVE-2026-34182
Threats
Impact
Low
A flaw was found in the Linux kernel's IPv6 networking stack. A use-after-free vulnerability exists in the `ip6_finish_output2()` function, where a cached pointer to the IPv6 destination address can become stale after memory reallocation. An attacker could potentially exploit this to leak sensitive kernel data, misdirect network traffic, or cause a system crash (Denial of Service).
7.0 (High)
Affected products
Fixed
4 products, the same list as for
CVE-2026-34182
Threats
Impact
Important
A flaw was found in the Linux kernel's RDMA/rxe component. A local user could exploit a memory corruption vulnerability in the `free_rd_atomic_resources()` function by updating the `max_dest_rd_atomic` value before the old array is properly freed, leading to an out-of-bounds write. This issue can cause a system crash, resulting in a denial of service (DoS).
7.3 (High)
Affected products
Fixed
4 products, the same list as for
CVE-2026-34182
Threats
Impact
Moderate
A flaw was found in the Linux kernel's Remote Direct Memory Access (RDMA) subsystem, specifically within the rxe component. A local, unprivileged user could exploit a race condition during a queue pair modification operation. This could lead to a use-after-free vulnerability, allowing the attacker to cause a system crash and resulting in a Denial of Service (DoS).
7.0 (High)
Affected products
Fixed
4 products, the same list as for
CVE-2026-34182
Threats
Impact
Moderate
A flaw was found in PCRE2. An out-of-bounds write vulnerability exists in the `pcre2_dfa_match` function due to improper size checking when reusing cached workspace blocks. A remote attacker could exploit this by providing a specially crafted regular expression or a recursive pattern in conjunction with a small heap limit. This could lead to data corruption or potentially arbitrary code execution, compromising the integrity and availability of the system.
8.2 (High)
Affected products
Fixed
4 products, the same list as for
CVE-2026-34182
Threats
Impact
Important
A flaw was found in PCRE2, a library for processing regular expressions. The `pcre2_jit_match` function, which handles just-in-time (JIT) compilation for regular expressions, incorrectly manages memory when processing certain inputs. This memory corruption vulnerability could allow a local attacker to cause the application to crash, leading to a denial of service, or potentially execute unauthorized code.
7.4 (High)
Affected products
Fixed
4 products, the same list as for
CVE-2026-34182
Threats
Impact
Important
A flaw was found in the Linux kernel. A local attacker or untrusted guest virtual machine can exploit this vulnerability by transmitting network packets containing malformed checksum metadata into the IPv4 networking subsystem. This failure to validate checksum metadata can corrupt memory during packet handling, potentially leading to arbitrary code execution on the host, a system crash resulting in Denial of Service (DoS), or information disclosure of sensitive memory.
8.8 (High)
Affected products
Fixed
4 products, the same list as for
CVE-2026-34182
Threats
Impact
Important
A flaw was found in pcre2. When an application processes attacker-controlled regular expressions using certain Just-In-Time (JIT) compiler interfaces, an out-of-bounds write with arbitrary data can occur. An attacker could exploit this vulnerability to achieve arbitrary code execution, corrupt memory, or cause a denial of service (DoS).
7.6 (High)
Affected products
Fixed
4 products, the same list as for
CVE-2026-34182
Threats
Impact
Important
The system certificate authority (CA) store in Red Hat products, distributed via ca-certificates RPM packages, included multiple root CA certificates of authorities, which signed intermediate CA certificates with weak private keys issued by the eMudhra certificate authority. A man-in-the-middle attacker could use this flaw to issue certificates for arbitrary host names signed by the weak intermediate CA certificates, which would be considered trusted by a TLS/SSL client using system CA store and cause such clients to connect to malicious sites. Due to inability to only distrust specific intermediate certificates in all clients using the system CA store, root CA certificates of authorities that signed weak intermediate CA certificates are being removed.

Exploitation requires local access with the ability to create symlinks in a directory that a privileged program later processes with acl_get_file() or acl_set_file(). In default RHEL and OpenShift CoreOS configurations, standard file permission settings limit where unprivileged users can create symlinks, reducing the practical attack surface.

"text": "This IMPORTANT-severity flaw affects the Linux kernel as shipped in Red Hat products, including the kernel and kernel-rt packages in Red Hat Enterprise Linux and the kernels shipped in Red Hat In-Vehicle OS. The IPv4 networking subsystem does not validate packet checksum metadata before completing a checksum: when a packet with a malformed checksum_start value enters the IPv4 stack, skb_checksum_help() can write out of bounds and corrupt the network header and other kernel memory (CWE-787). A local attacker or an untrusted guest virtual machine able to transmit such packets into an affected host could exploit this to crash the system (denial of service), disclose sensitive kernel memory, or potentially execute arbitrary code on the host. Red Hat tracks this flaw as a KEV active-exploit case. All currently tracked Red Hat product streams are marked affected, and fixes are being pursued by the responsible Red Hat product teams under delegated resolution. Red Hat\u0027s severity differs from the upstream assessment: Red Hat assigns a CVSS 3.1 score of 8.8 (IMPORTANT, AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H), while the CVE.org record assigns 9.3 (CRITICAL, AV:L/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H); the two assessments differ on the privileges-required metric.",
