CVE-2026-68174

The vulnerability CVE-2026-68174 affects the Linux kernel tracing subsystem. In struct trace_event_call, the module pointer and the refcnt atomic share a union, so for dynamic events (kprobe, uprobe, fprobe, eprobe, wprobe) the refcnt may be non-zero and cause call->module to appear as a small...

CVE-2026-68084

The CVE concerns the Linux kernel staging: vme_user component, specifically the tsi148 bridge. The root cause is a leaked location monitor resource (lm_resources) because tsi148_remove() did not free lm_resources when unbinding or unloading, unlike other resources. The fix is to free the lm_resou...

Security update for perl

This update for perl fixes the following issues: CVE-2026-8376: heap buffer overflow when compiling regular expressions with a repeated fixed string on 32-bit builds bsc1266304. CVE-2026-12087: Socket's packipmreqsource can copy adjacent heap memory into the returned packed structure bsc1268349...

kernel: xen/privcmd: fix double free via VMA splitting

A flaw was found in the Linux kernel's xen/privcmd module. A local user could exploit this by performing a partial unmapping of a privcmd memory region. This action causes a Virtual Memory Area VMA to split, leading to duplicated internal memory pointers. As a result, the same memory can be freed...

kernel: selinux: fix overlayfs mmap() and mprotect() access checks

A flaw was found in the Linux kernel's SELinux security module when handling overlayfs. The existing security model for overlayfs does not properly enforce access controls for mmap and mprotect operations. This oversight could allow a local attacker to bypass intended security policies, potential...

Astra Linux – Vulnerability in Node.js

A flaw in Node.js’s buffer allocation logic can expose uninitialized memory when allocations are interrupted, especially when using the vm module with the timeout option. Under certain timing conditions, buffers allocated using Buffer.alloc and other TypedArray instances like Uint8Array may conta...

Astra Linux – Vulnerability in grub2

A vulnerability in the GRUB2 bootloader has been identified in the normal module. This flaw, a memory use-after-free issue, occurs because the normalexit command is not properly unregistered when its related module is unloaded. An attacker can exploit this condition by invoking the command after...

Astra Linux – Vulnerability in grub2

A vulnerability related to operations after freeing memory has been discovered in GRUB’s gettext module. This flaw arises from a programming error where the gettext command remains registered in memory even after its associated module is unloaded. An attacker can exploit this condition by invokin...
