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().","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/2a3a29e90021806ea00527f6458cfd2edb58b42a","https://git.kernel.org/stable/c/369e4635d04801f394d5bd42556f21029e95ff93","https://git.kernel.org/stable/c/5cadc66b534fe8140441916200a20c7efb06a388","https://git.kernel.org/stable/c/7285f004293e7dc043c55369c0dbe8350b28cc45","https://git.kernel.org/stable/c/b594c23f584ab032a5eae809eee81b809dd27330"],"products":[],"source":"nvd","synced_at":"2026-10-22T16:41:11.231219466+00:00"},"epss":{"cve":"CVE-2026-92519","score":0.00209,"percentile":0.10905,"date":"2026-10-25"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
