"value": "AV:L - An unprivileged local process can add a crafted PKCS#8 RSA private key to its own keyring and invoke KEYCTL_PKEY_QUERY, which selects qat-rsa and reaches the vulnerable key setup path.\nAC:L - With an active QAT asymmetric service and PKCS#8 parser, an oversized CRT integer deterministically causes unsigned offset underflow and an out-of-bounds memcpy. No race or attacker-uncontrollable condition is required.\nPR:L - An ordinary user can create, search, and use keys in a personal process, thread, or session keyring. No capability, administrator privilege, or user namespace is required.\nUI:N - The attacker directly performs the add_key and keyctl system calls without any victim action.\nS:U - The vulnerable QAT driver and the corrupted kernel resources share the same security authority. Ordinary kernel privilege escalation does not cross a CVSS scope boundary.\nC:H - The controlled kernel-memory overwrite can corrupt page tables, credentials, or control-flow objects and plausibly yield code execution with access to protected kernel memory.\nI:H - Attacker-controlled CRT bytes are written outside the coherent DMA allocation, potentially through multiple CRT components. This can provide powerful kernel-memory corruption and control-flow hijacking primitives.\nA:H - The invalid destination can cause an immediate kernel fault or corrupt unrelated kernel memory and subsequently panic or hang the system. The attack is repeatable."
