CVE-2025-52515

Service interruption via issimian driver race

Published Jan 5, 2026 · Updated Jan 5, 2026

Race condition in the Camera component of Samsung Exynos processors allows local users to interrupt service through the issimian driver. The issimian device driver performs an out-of-bounds memory access when concurrent activity triggers the documented race condition. Exploitation requires local access and winning a high-complexity race; the documented consequence is availability loss, with no reported data disclosure or modification.
