In that case, the allocated TD is leaked.\n\nFix this by deallocating the TD when mlx5_ib_enable_lb() returns an\nerror. Also return 0 explicitly in the no-loopback-capability success\nbranch, and move dev->lb.mutex initialization to mlx5_ib_stage_init_init().","published":"2026-08-15T06:22:42.000Z","lastModified":"2026-10-16T20:17:25.000Z","status":"Received","sourceIdentifier":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","cvss":{"version":"3.1","score":7.8,"severity":"HIGH","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"},"cwe":[],"affected":[],"epss":{"score":0.00129,"percentile":0.02526,"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":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (0.13%).
