CVE-2026-53277

A flaw was found in the Kernel-based Virtual Machine (KVM) component of the Linux kernel on arm64 architectures. This vulnerability occurs because certain page table walk operations, used in fault injection and Address Translation (AT) emulation, do not properly acquire a Sleepable Read-Copy Update (SRCU) lock. This omission could lead to inconsistencies in memory slot management, potentially causing system instability or unexpected behavior within the virtualized environment.
