Local privilege escalation in Intel QuickAssist Technology (QAT) software drivers for Windows before version 1.13 lets an authenticated low-privileged user elevate to higher privileges through improper input validation in a Ring 3 user-application code path. The flaw was reported by Intel PSIRT (INTEL-SA-01387) and carries a CVSS 4.0 base of 8.5, but there is no public exploit identified at time of analysis and EPSS is a low 0.03% (8th percentile). SSVC scores exploitation as none and not automatable, consistent with a driver bug that requires prior local, authenticated access.
Local privilege escalation in Intel QuickAssist Technology (QAT) software drivers for Windows before version 1.13 lets an authenticated, unprivileged local user escalate to higher privileges via an out-of-bounds write (CWE-787) in Ring 3 user-application code. The flaw carries a CVSS 4.0 base score of 8.5 with total technical impact but is not known to be exploited - CISA's SSVC framework rates exploitation as 'none' and EPSS is negligible at 0.01% (3rd percentile), with no public exploit identified at time of analysis.
