However,\nbpf_jit_free() fails to free jit_data->ctx.offset, which causes a\nmemory leak of the JIT context offsets array.\n\nFix this by adding the missing kfree(jit_data->ctx.offset) in\nbpf_jit_free().\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.\n\n## Vendor advisories\n\n- **Red Hat VEX** · Moderate · updated 2026-10-05 · [vex](https://security.access.redhat.com/data/csaf/v2/vex/2026/cve-2026-92519.json)","depth":"sunlit","depthScore":30,"depthScoreParts":{"impact":30.3,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[{"seq":216281,"id":"CVE-2026-92519","ts":1791274056858,"field":"cvss","old":null,"new":"5.5"},{"seq":216280,"id":"CVE-2026-92519","ts":1791274056858,"field":"severity","old":"none","new":"medium"}]}
