Tables with a\nnon-zero start sector can therefore pass an absolute mapped-device block\nto metadata_current_marked().\n\nIf the absolute block is beyond the current writeset size,\nwriteset_marked() tests past the end of the in-core bitset.  KASAN reports\nthis as a vmalloc-out-of-bounds access.\n\nApply the target offset before calculating the era block so writeset\nlookups use the target-relative block number.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":8.8},"cwes":["CWE-125"],"references":["https://git.kernel.org/stable/c/1fcb5e29dd7a5b85adb9d8b539911741d878e829","https://git.kernel.org/stable/c/7e1822f83c5a1ee7b4a19e98edde8770a10b4c71","https://git.kernel.org/stable/c/9946a7176bd8c25ddd6e5f1799c54e572ee6bf0f","https://git.kernel.org/stable/c/a868196f03c2b19418ae3d2b69e195d668a271e5","https://git.kernel.org/stable/c/bafe3e720cdac38cd7ea4eb7852a8f2dbe1bbfe6"],"products":[],"source":"nvd","synced_at":"2026-10-21T03:56:58.798400159+00:00"},"epss":{"cve":"CVE-2026-72107","score":0.0065,"percentile":0.50882,"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).
