If mlx5hws_matcher_resize_set_target() fails, the\nreplacement matcher is not attached anywhere and is leaked.\n\nFix the leak by destroying the replacement matcher before returning from\nthe resize-target failure path.\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\npresent in v7.1.1.\n\nAn x86_64 allyesconfig build showed no new warnings. As we do not have a\nmlx5 HWS-capable device to test with, no runtime testing was able to be\nperformed.","published":"2026-08-15T06:21:12.000Z","lastModified":"2026-08-17T06:18:01.000Z","status":"Received","sourceIdentifier":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","cvss":null,"cwe":[],"affected":[],"epss":{"score":0.00206,"percentile":0.10485,"date":"2026-10-27","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.
