Astra Linux – Vulnerability in Linux

A issue was discovered in Linux: improper handling of VMIO|VMPFNMAP vmas in KVM can bypass RO checks and may cause pages to be freed while still accessible by the VMM and guest. This allows users who have the ability to start and control a VM to read/write random pages of memory, potentially...

In the Linux kernel, the following vulnerability has been resolved: drm/msm: Fix bootup splat with separategpudrm modparam The drmgemforeachgpuvmbo call from lookupvma accesses drmgemobj.gpuva.list, which is not initialized when the drm driver does not support DRIVERGEMGPUVA feature. Enable it fo...

Astra Linux – Vulnerability found in Linux 5.10, Linux 5.15

A issue was discovered in include/asm-generic/tlb.h in the Linux kernel before version 5.19. Due to a race condition between unmapmappingrange and munmap, a device driver can free a page while it still has stale TLB entries. This only occurs in situations involving VMPFNMAP VMAs...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: drm/amdkfd: Added a synchronization step after creating a vram block. Data corruption will occur on vrams allocated by svm if the initialization is not complete and an application writes to the memory. Adding a synchronization st...

CVE-2026-42006

An attacker can cause uncontrolled memory usage with excessive bracing over IMAP. The fix in CVE-2026-27857 was incomplete, only blocking one way of doing this, so there was still another way left open. In particular, the fix was for closing braces, but you could still use open braces to bypass t...

CVE-2026-43433

A flaw was found in the Linux kernel's rustbinder component. If a local process gains the ability to write to its own virtual memory area VMA, it could exploit a time-of-check to time-of-use TOCTOU vulnerability. This allows the process to alter the offsets array during a transaction before it is...

CVE-2026-43292

A flaw was found in the Linux kernel. When the CONFIGPAGEOWNER option is enabled, the kernel's memory management mm/vmalloc component can experience Read-Copy-Update RCU stalls during virtual memory allocation cleanup. This occurs because freeing Kernel Address Sanitizer KASAN shadow pages trigge...
