CVE-2026-40290: CWE-416: Use After Free in OP-TEE optee_osCVE-2026-40290 0 A Use-After-Free (UAF) vulnerability exists in OP-TEE's optee_os versions from 3. 16. 0 up to but not including 4. 11. 0. The flaw arises from a race condition in the shared memory teardown logic when OP-TEE is configured as an SPMC for secure partitions (CFG_SECURE_PARTITION=y). Specifically, the sp_mem_remove() function frees memory without proper locking, allowing concurrent threads to dereference freed pointers. This vulnerability is addressed in version 4. 11. 0.
