CVE-2026-40257: CWE-787: Out-of-bounds Write in OP-TEE optee_osCVE-2026-40257 0 An out-of-bounds write vulnerability exists in OP-TEE's ARM Crypto Extensions accelerated SHA-3 implementation in versions starting from 3.21.0 up to but not including 4.11.0. This off-by-one error causes a heap overflow that corrupts TEE kernel memory following the hash state when built with CFG_CRYPTO_WITH_CE82=y. Version 4.11.0 includes a patch. A workaround is to disable the SHA3 Crypto Extensions by setting CFG_CRYPTO_WITH_CE82=n. Join the discussion | CVE Database V5 | 07/06/2026, 16:26:20 UTC Added: 07/06/2026, 16:52:42 UTC |
