CVE-2026-53273 tee: optee: prevent use-after-free when the client exits before the supplicant

In the Linux kernel, the following vulnerability has been resolved: tee: optee: prevent use-after-free when the client exits before the supplicant Commit 70b0d6b0a199 "tee: optee: Fix supplicant wait loop" made the client wait as killable so it can be interrupted during shutdown or after a...

CVE-2026-53273

CVE-2026-53273 describes a use-after-free in the Linux kernel TEE/OP-TEE path. When a client exits before the supplicant finishes processing, freed request memory could be dereferenced, enabling a potential crash or code execution path. The root cause is a race around request lifetime between the...
