Based on\ncode in mb_free_blocks(), fast commit replay can end up marking as free\nblocks that are already marked as such. This causes corruption of the\nbuddy bitmap so we need to regenerate it in that case.","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/6b0d48647935e4b8c7b75d1eccb9043fcd4ee581","https://git.kernel.org/stable/c/78327acd4cdc4a1601af718b781eece577b6b7d4","https://git.kernel.org/stable/c/94ebf71bddbcd4ab1ce43ae32c6cb66396d2d51a","https://git.kernel.org/stable/c/c1317822e2de80e78f137d3a2d99febab1b80326","https://git.kernel.org/stable/c/c9b528c35795b711331ed36dc3dbee90d5812d4e"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T21:45:59.823092188+00:00"},"epss":{"cve":"CVE-2024-26601","score":0.00292,"percentile":0.21777,"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).
