Title
Use-after-free in Linux kernel's net/sched: cls_u32 component
Summary
A use-after-free vulnerability in the Linux kernel's net/sched: cls_u32 component can be exploited to achieve local privilege escalation.
If tcf_change_indev() fails, u32_set_parms() will immediately return an error after incrementing or decrementing the reference counter in tcf_bind_filter(). If an attacker can control the reference counter and set it to zero, they can cause the reference to be freed, leading to a use-after-free vulnerability.
We recommend upgrading past commit 04c55383fa5689357bcdd2c8036725a55ed632bc.

CVE-2023-3776 (GCVE-0-2023-3776)

Title
Use-after-free in Linux kernel's net/sched: cls_fw component
Summary
A use-after-free vulnerability in the Linux kernel's net/sched: cls_fw component can be exploited to achieve local privilege escalation.
If tcf_change_indev() fails, fw_set_parms() will immediately return an error after incrementing or decrementing the reference counter in tcf_bind_filter(). If an attacker can control the reference counter and set it to zero, they can cause the reference to be freed, leading to a use-after-free vulnerability.
We recommend upgrading past commit 0323bce598eea038714f941ce2b22541c46d488f.

CVE-2023-39191 (GCVE-0-2023-39191)

Title
Kernel: ebpf: insufficient stack type checks in dynptr
Summary
An improper input validation flaw was found in the eBPF subsystem in the Linux kernel. The issue occurs due to a lack of proper validation of dynamic pointers within user-supplied eBPF programs prior to executing them. This may allow an attacker with CAP_BPF privileges to escalate privileges and execute arbitrary code in the context of the kernel.
Severity
8.2 (High)

Exploitation: none
Automatable: no
Technical Impact: total

Title
Sev-es / sev-snp vmgexit double fetch vulnerability
Summary
A flaw was found in KVM AMD Secure Encrypted Virtualization (SEV) in the Linux kernel. A KVM guest using SEV-ES or SEV-SNP with multiple vCPUs can trigger a double fetch race condition vulnerability and invoke the `VMGEXIT` handler recursively. If an attacker manages to call the handler multiple times, they can trigger a stack overflow and cause a denial of service or potentially guest-to-host escape in kernel configurations without stack guard pages (`CONFIG_VMAP_STACK`).

Title
Kernel: tap: tap_open(): correctly initialize socket uid next fix of i_uid to current_fsuid
Summary
A flaw was found in the Linux kernel's TUN/TAP functionality. This issue could allow a local user to bypass network filters and gain unauthorized access to some resources. The original patches fixing CVE-2023-1076 are incorrect or incomplete. The problem is that the following upstream commits - a096ccca6e50 ("tun: tun_chr_open(): correctly initialize socket uid"), - 66b2c338adce ("tap: tap_open(): correctly initialize socket uid"), pass "inode->i_uid" to sock_init_data_uid() as the last parameter and that turns out to not be accurate.
Severity
5.5 (Medium)
CWE
- CWE-843 - Access of Resource Using Incompatible Type ('Type Confusion')
