Positive Technologies (AI Summary)

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description Certain Arm CPUs experience an issue where a broadcast TLBI;DSB sequence may complete before memory writes translated by an affected TLB entry are globally observed. This affects the completion of memory accesses translated by an invalidated TLB entry, though it does not prevent the actual invalidation of TLB entries.

Recommendations Enable the ARM64 WORKAROUND REPEAT TLBI workaround for affected CPUs. Follow any affected TLBI;DSB sequence with an additional TLBI;DSB to ensure all memory write effects are globally observed.
