CVE-2026-53210
The CVE-2026-53210 issue is in the Linux kernel’s Trusted Execution Environment (TEE) subsystem. A shm leak occurs in register_shm_helper() when TEE_IOC_SHM_REGISTER registers a zero-length shared memory, because shm is allocated before iov_iter_npages() and not freed if it returns 0; the code pa...
