This\ncan lead to an unexpected \"BUG: kernel NULL pointer dereference\" if\nthe corresponding decompressor isn't built-in.\n\nFix this by checking against `sbi->available_compr_algs` for each\nm_algorithmformat request.  Incorrect !erofs_sb_has_compr_cfgs preset\nbitmap is now fixed together since it was harmless previously.","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/118a8cf504d7dfa519562d000f423ee3ca75d2c4","https://git.kernel.org/stable/c/47467e04816cb297905c0f09bc2d11ef865942d9","https://git.kernel.org/stable/c/823ba1d2106019ddf195287ba53057aee33cf724","https://git.kernel.org/stable/c/eed24b816e50c6cd18cbee0ff0d7218c8fced199","https://git.kernel.org/stable/c/118a8cf504d7dfa519562d000f423ee3ca75d2c4"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T21:45:59.823092188+00:00"},"epss":{"cve":"CVE-2024-26590","score":0.00222,"percentile":0.12817,"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).
