This causes a NULL pointer dereference\nwhen sd_is_zoned() is called inside that function. Avoid this by removing\nthe call to sd_zbc_release_disk() in sd_probe() error path.\n\nThis change is safe and does not result in zone information memory leakage\nbecause the zone information for a zoned disk is allocated only when\nsd_revalidate_disk() is called, at which point sdkp->disk_dev is fully set,\nresulting in sd_disk_release() being called when needed to cleanup a disk\nzone information using sd_zbc_release_disk().","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/05fbde3a77a4f1d62e4c4428f384288c1f1a0be5","https://git.kernel.org/stable/c/0fcb0b131cc90c8f523a293d84c58d0c7273c96f","https://git.kernel.org/stable/c/3733439593ad12f7b54ae35c273ea6f15d692de3","https://git.kernel.org/stable/c/78f8e96df06e2d04d82d4071c299b59d28744f47","https://git.kernel.org/stable/c/c1f0187025905e9981000d44a92e159468b561a8"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T21:59:48.811064707+00:00"},"epss":{"cve":"CVE-2022-49376","score":0.00268,"percentile":0.19036,"date":"2026-10-31"},"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).
