Astra Linux – Vulnerability in Linux 5.10

A race condition was detected in the fs/proc/taskmmu.c file, which is part of the memory management sub-component in the Linux kernel. This issue may allow a local attacker with user privileges to cause a denial of service...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: fs/proc/taskmmu: The issue of losing the “young/dirty” bits during the pagemap scan has been fixed. The function makeuffdwpwppte used to perform these operations was previously executed as follows: c pte = ptepgetptep;...

The vulnerability of the pagemap_scan_get_args() function in the fs/proc/task_mmu.c module of the Linux file system allows a hacker to induce a service failure.

The vulnerability of the pagemapscangetargs function in the fs/proc/taskmmu.c module of the Linux file system’s support for the kernel’s file system is related to integer overflow. Exploiting this vulnerability could allow an attacker to cause a service failure...

CVE-2025-40009

CVE-2025-40009 : In the Linux kernel, a null pointer dereference can occur in the PAGEMAP_SCAN path when vec_len = 0 is used. The root cause is an unchecked p->vec_buf in the PAGEMAP_SCAN flow, which leads to dereferencing NULL in pagemap_scan_backout_range(). The issue is fixed by explicitly ...
