CVE-2026-53020

A flaw was found in the Linux kernel. A race condition can occur during Translation Lookaside Buffer TLB synchronization when the page table is traversed and modified without properly holding the necessary page table lock. This vulnerability may allow for unpredictable system behavior or...

CVE-2026-53057

A flaw was found in the Linux kernel, specifically within the Input/Output Memory Management Unit IOMMU for RISC-V architectures. This vulnerability occurs because the system does not properly clear out old memory translation information, known as Translation Lookaside Buffer TLB and context cach...

CVE-2026-53201

CVE-2026-53201 affects the Linux kernel, with multiple sources (NVD, OSV, Debian security tracker, Ubuntu, etc.) describing a fix that reverts a prior optimization. The issue arises because the idle-skip optimization in the DRM/xe path can bypass GuC suspend, potentially skipping the context-swit...

CVE-2026-53020

In the Linux kernel, the following vulnerability has been resolved: um: Fix potential race condition in TLB sync During the TLB sync, we need to traverse and modify the page table, so we should hold the page table lock. Since full SMP support for threads within the same process is still missing,...

CVE-2026-53020

The CVE-2026-53020 entry documents a Linux kernel issue: a race condition during Translation Lookaside Buffer (TLB) synchronization when the page table is traversed and modified without holding the proper page table lock. The root cause is the lack of adequate locking during TLB sync, which can l...

Astra Linux – Vulnerability in Linux 5.10, Linux

The mm/mremap.c file in the Linux kernel before version 5.13.3 contains a use-after-free issue due to a stale Translation Look-And-Reduce TLB table, as the rmap lock is not held during a PUD move...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: s390: Disabling ARCHWANTOPTIMIZEHUGETLBVMEMMAP According to Luiz Capitulino, enabling HVO on s390 leads to reproducible crashes. The issue arises because the kernel’s page tables are modified without flushing the corresponding TL...

In the Linux kernel, the following vulnerability has been resolved: x86/CPU/AMD: Disabling INVLPGB on Zen2 AMD Cyan Skillfish Family 17h, Model 47h, Stepping 0h has a issue that causes system errors and panics when performing TLB flush using INVLPGB. However, the problem arises from misconfigured...

Astra Linux – Vulnerability found in Linux 5.15, Linux 5.10

A issue was discovered in the x86 KVM subsystem of the Linux kernel before version 5.18.17. Unprivileged guest users can compromise the guest kernel because TLB flush operations are mishandled in certain KVMVCPUPREEMPTED situations...

Astra Linux – Vulnerabilities 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...
