Description

A flaw was found in the Linux kernel, affecting systems running on certain Arm processors. This vulnerability involves an issue with how the system handles Translation Lookaside Buffer Invalidation (TLBI) operations. Specifically, a sequence of operations intended to invalidate memory translations may complete before all related memory writes are fully observed across the system. This could lead to inconsistencies in memory access, although the TLB entries themselves are correctly invalidated.
