When name_size() returns an error (unrecognized hash algorithm),\n   the function returns directly without destroying the buffer.\n\n2. On the success path, the buffer is never destroyed before\n   returning.\n\nAll other error paths in the function correctly call\ntpm_buf_destroy() before returning.\n\nFix both by adding the missing tpm_buf_destroy() calls.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","score":5.5},"cwes":[],"references":["https://git.kernel.org/stable/c/2f434be87e256fd58254f60ddf5d7d58e775ca0b","https://git.kernel.org/stable/c/f0f75a3d98b7959a8677b6363e23190f3018636b","https://git.kernel.org/stable/c/f8775d9d9062da662cc861f9ff7722a65896d4cd"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T22:36:28.938604137+00:00"},"epss":{"cve":"CVE-2026-46096","score":0.00121,"percentile":0.01871,"date":"2026-11-01"},"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).
