Search: CVE-2025-10263

CVE-2025-10263 is a critical race condition vulnerability in the Linux kernel on ARM processors, including Arm C1-Ultra and related cores. It involves improper synchronization during Translation Lookaside Buffer Invalidation (TLBI) operations when memory permissions change, allowing a local attacker to write to memory resources owned by higher privilege levels. This flaw can enable privilege escalation to kernel level or guest VM escape to the hypervisor, potentially leading to complete system compromise. Red Hat has acknowledged the issue and is working on fixes for affected products such as Red Hat OpenShift Container Platform 4.12.96. No known exploits are reported in the wild at this time.
