CVE-2025-10263 could allow for privilege escalation on affected systems due to a specific timing condition during a memory permission change. Fundamentally it comes down to completion of affected memory accesses might not be guaranteed by the completion of a TLBI.<\/p>\n<p>CVE-2025-10263 while assigned last year was only made public today for this issue that can allow writes to resources owned by a higher exception level as a means of achieving privilege escalation. Among the Arm cores affected are the latest C1-Ultra and C1-Premium as well as older cores such as Neoverse V3 &#038; V3AE, Neoverse V2, Neoverse V1, Neoverse N2, and Neoverse N1. Additionally, the Cortex-X925, Cortex-X4, Cortex-X3, Cortex-X2, Cortex-X1 &#038; X1C, Cortex-A710, Cortex-A78, A78AE &#038; A78C, Cortex-A77, Cortex-A76 &#038; A76AE are all affected as well.\n<\/p>\n<p>The software workaround is that for any software performing TLB invalidation applying to stage 1 or stage 1 and 2 information must perform an additional TLBI and DSB.
