CVE-2026-64438

Summary of CVE-2026-64438 : In the Linux kernel’s crypto: qat path, a race during VF2PF teardown could cause use-after-free of per-VF state (vf_info) due to tearing down per-VF locks and state before in-flight VF2PF work completes. The fix introduces a PF-local flag (vf2pf_disabled) that gates wo...

CVE-2026-64383

CVE-2026-64383 affects the Linux kernel’s SMB2 client path, specifically the SMB2_flush() replay handling. The issue arises when a replayable flush response is received and a retry fails before a replacement response is stored, causing a second free of the stale buffer due to persistent bookkeepi...
