NVD description

OP-TEE OS through 4.10.0, fixed in commit 8794043, contains a use-after-free vulnerability in the Trusted Application loader that allows attackers with the ability to load a signed Trusted Application to corrupt secure-world kernel memory by setting the TA_FLAG_CONCURRENT flag in a user TA signed header. Attackers can cause two concurrent sessions to operate on the same shared context without locking, corrupting the uctx->vm_info.regions list during memref parameter mapping and unmapping to free vm_region nodes still in use, resulting in a use-after-free in S-EL1 secure-world kernel memory.

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
