CVE-2025-10263 is a memory-ordering vulnerability in certain Arm processor designs. A broadcast translation lookaside buffer invalidation and its associated synchronization can complete before writes made through the invalidated translation become globally observable. Consequently, memory writes may take effect after write permissions have been revoked, potentially allowing writes to resources owned by a higher exception level. Affected designs include C1-Ultra, C1-Premium, Neoverse V3/V3AE, V2, V1, N2 and N1; Cortex-X925, X4, X3, X2, X1/X1C; and Cortex-A710, A78/A78AE/A78C, A77 and A76/A76A.
