NVD description

OP-TEE OS through 4.10.0, fixed in commit 0aadfc2, contains a null pointer dereference vulnerability in the Widevine pseudo-TA open_session handler that allows Normal World clients to cause a denial of service when CFG_WIDEVINE_PTA is enabled. Attackers can open a session directly on the Widevine PTA to trigger an unconditional dereference of a NULL calling session pointer via is_user_ta_ctx(), faulting the TEE at S-EL1 and crashing the trusted execution environment.

    My two cents is that this democratises AI-availability and Privacy. Doom on hardware Y is an existence proof and dies there! For fulfilling your curiosity running a glm-5.1 UD-IQ1_M on one Mac studio M3 ultra plus a iogpu sysctl made us at #byteray #CVE-2026-55706 a 27-year old bug on #OpenBSD just a few weeks after Mythos worked heavily on the same part of the its kernel! Btw, it wasn’t just an llm prompt to hunt bugs, however a bit more work on agents, pairing 1bit quant with precomputed CPG/DFG analysis yet autonomously, RAG over mcp. The setup also leads us to hundreds of advisories including: #CVE-2026-55706 #CVE-2026-71967 #CVE-2026-71968 #CVE-2026-71969 #CVE-2026-71970 #CVE-2026-71971 #CVE-2026-71972 #CVE-2026-71973 #CVE-2026-71974 #CVE-2026-74220 #CVE-2026-74221 #CVE-2026-74222 #CVE-2026-74223 #CVE-2026-74224 #CVE-2026-74225 #CVE-2026-56099 #CVE-2026-56101 #CVE-2026-56102 #CVE-2026-56103 Yet all of these are just a small use case not a benchmark so I agree with you on that part @theByteRay
