Path deletion\nflushes the cache and then frees the path with kfree_rcu(), but a\nlookup that already holds the path can insert a new cache entry\nafter the flush. The cache then points at freed memory.\n\nSet MESH_PATH_DELETED before flushing, and skip inserting a cache\nentry if the path or MPP path is already deleted. Check this under\nthe cache walk lock so it is ordered with the flush. Use WRITE_ONCE()\nfor the deletion flag updates because the cache check reads flags\nwithout taking state_lock.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/0117f1aa189495e6f1ff608681678817995aee39","https://git.kernel.org/stable/c/128e800a41270ab197b1cc8043637a2924865608","https://git.kernel.org/stable/c/93da3ec938bfdcfb3899428f04c6d0c56fe32952","https://git.kernel.org/stable/c/ebb7cba623d38733d33d79a8c7442f5ea04c0fb0","https://git.kernel.org/stable/c/ee3aadc43ea69d98f666431e787137ac0badbb85"],"products":[],"source":"nvd","synced_at":"2026-10-22T16:41:11.231219466+00:00"},"epss":{"cve":"CVE-2026-98699","score":0.00168,"percentile":0.06029,"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).
