UBUNTU-CVE-2026-93254

In the Linux kernel, the following vulnerability has been resolved: arm64: entry: Avoid unnecessary localirqdisable on kernel exit Currently, when exiting to kernel mode, we attempt involuntary preemption. The preemption logic expects IRQs to be disabled, which is why we call localirqdisable befo...

UBUNTU-CVE-2026-93239

In the Linux kernel, the following vulnerability has been resolved: arm64: mm: Fix the lockless page-table walk in showpte showpte walks page tables locklessly and can run with interrupts enabled. A concurrent teardown can free a table page while it is being walked. It can also clear a parent ent...

UBUNTU-CVE-2026-93211

In the Linux kernel, the following vulnerability has been resolved: nfsd: initialize DRC hash table before registering shrinker shrinkerregister precedes the INITLISTHEAD loop and the drchashsize store.

CVE-2026-93266

The Linux kernel on arm64 architecture contains a vulnerability in the RSI attestation token initialization (rsi_attestation_token_init). The root cause is a field-spanning write triggered by FORTIFY when copying a 64-byte challenge into the &regs.a1 field, which is treated as an 8-byte destinati...

CVE-2026-93256 arm64: hibernate: mask DAIF before restoring hibernated kernel

In the Linux kernel, the following vulnerability has been resolved: arm64: hibernate: mask DAIF before restoring hibernated kernel The arm64 hibernate code manages the exception masking in an unsound way, leading to potential crashes and/or warnings during resume. When a hibernation image is save...

CVE-2026-93256

The Linux kernel contains an issue in the arm64 hibernate implementation where exception masking is managed unsafely during the resume process. Specifically, when a hibernation image is saved via swsusp_arch_suspend(), all DAIF exceptions are masked. However, during resume via swsusp_arch_resume(...

CVE-2026-93254

The Linux kernel contains an issue in the arm64 architecture where local_irq_disable() is redundantly called during kernel exit. This unnecessary call occurs in the __el1_irq() path and irqentry_exit_to_kernel_mode_preempt() context, where interrupts are already disabled. This redundancy causes p...

CVE-2026-93239

The Linux kernel (arm64 architecture) contains a vulnerability in the mm subsystem related to the lockless page-table walk in show_pte() . Because show_pte() walks page tables without holding locks and can run with interrupts enabled, a concurrent teardown can free a table page during the walk. A...
