If there is some load on the system we can exit before\nthe cipher operation is done and the buffer we read from/write to\nis already removed from the stack. This will e.g. result in NULL\npointer dereference errors in the DCP driver during blob creation.\n\nFix this by waiting for the AEAD cipher operation to finish before\nresuming the seal and unseal 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":["CWE-476"],"references":["https://git.kernel.org/stable/c/04de7589e0a95167d803ecadd115235ba2c14997","https://git.kernel.org/stable/c/c75e0272289eae18c5379518a9c56ef31d65cc7d"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T21:57:34.731061660+00:00"},"epss":{"cve":"CVE-2024-50281","score":0.00185,"percentile":0.08118,"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).
