This skips rate_control_deinitialize() and\nleaks the initialized local->rate_ctrl.\n\nFix this by adding a fail_band label that shares the rate-control cleanup\npath before falling through to the remaining teardown.\n\nThe bug was first flagged by an experimental analysis tool we are\ndeveloping for kernel memory-management bugs while analyzing\nv6.13-rc1. The tool is still under development and is not yet publicly\navailable. Manual inspection confirms that the bug is still present in\nv7.1-rc7.\n\nAn x86_64 allyesconfig build showed no new warnings. As we do not have a\nsuitable mac80211 device/driver combination to test with, no runtime\ntesting was able to be performed.","published":"2026-08-15T06:20:59.000Z","lastModified":"2026-08-17T06:17:58.000Z","status":"Received","sourceIdentifier":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","cvss":null,"cwe":[],"affected":[],"epss":{"score":0.0022,"percentile":0.12371,"date":"2026-10-26","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"unknown","text":"Not yet scored.
