Astra Linux – Vulnerability found in Linux 6.1, Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: pstore: ramcore: Fixed an issue where an incorrect success return occurred when vmap failed. In persistentramvmap, vmap might return NULL upon failure. If the offset is non-zero, adding offsetinpagestart causes the function to...

CVE-2026-43124

A flaw was found in the Linux kernel's pstore ramcore component. A local attacker could exploit a vulnerability where the persistentrambuffermap function incorrectly returns success even when the underlying vmap memory mapping operation fails. This occurs if a non-zero offset is used, leading to...

CVE-2026-43124

The CVE-2026-43124 issue affects Linux kernel pstore ram_core, where persistent_ram_vmap() could return a non-NULL pointer after vmap() failed, causing persistent_ram_buffer_map() to incorrectly report success and potentially dereference an invalid address on access, leading to a crash (DoS). Roo...
