CVE-2026-53312
The CVE-2026-53312 issue affects the Linux kernel in the iommu/riscv invalidation path. The root cause is integer overflow when handling sign-extended page tables (ULONG_MAX) that could lead to an infinite loop during invalidation. The patch removes these overflows and relocates the +1 to avoid l...

CVE-2026-53057
The CVE-2026-53057 entry describes a Linux kernel IOMMU issue for RISCV: after updating DDT/PDT entries, the system must invalidate TLB and context cache entries. The fix adds riscv_iommu_iodir_iotinval() to perform the required IOTINVAL-based invalidations in accordance with the RISC-V IOMMU spe...
Astra Linux – Vulnerability found in Linux 5.10, Linux 5.15
In the Linux kernel, the following vulnerability has been resolved: arm64: Set UXN on swapper page tables This issue was accidentally fixed upstream via c3cee924bd85 "arm64: head: cover the entire kernel image in the initial ID map", as part of a major refactoring of the arm64 boot process. This...
Astra Linux – Vulnerability in Linux 5.10
In the Linux kernel, the following vulnerabilities have been resolved: drm/panthor: Fixed UAF issues on kernel BO VA nodes. If the MMU is down, panthorvmunmaprange might return an error. We expect the page table to still be updated; if the MMU is blocked, the rest of the GPU should also be blocke...
Astra Linux – Vulnerability in Linux 5.10
In the Linux kernel, the following vulnerability has been resolved: mm/mremap: Fixed the WARN message emitted by uffd when remap events are disabled. Registering userfaultd on a VMA that spans at least one PMD, and then using mremap to remap that VMA, may trigger a WARN message when recovering fr...

CVE-2026-34192
CVE-2026-34192 affects GPU driver components (GPU DDK) where MMU page tables are freed without proper cleanup in an error path, allowing a non-privileged user to trigger use-after-free of physical memory. The issue is caused by _MMU_AllocLevel error recovery paths that leave dangling page table e...
PT-2026-50865
Name of the Vulnerable Software and Affected Versions GPU DDK affected versions not specified Description Software run by a non-privileged user can execute improper GPU system calls to trigger an error path, resulting in a Use-After-Free UAF of GPU page tables. This occurs because an error recove...
