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().","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":7.8},"cwes":[],"references":["https://git.kernel.org/stable/c/2c3b2667dad69d56774b79db763acb3a1bee0fc0","https://git.kernel.org/stable/c/37fc3cc0f924fd8d0f0cf87b92672dec75a32e57","https://git.kernel.org/stable/c/65e344925fa30abf50c8de8c150b397715fa2066","https://git.kernel.org/stable/c/e79389115b9d27287ff6230a9750675106ed7668","https://git.kernel.org/stable/c/f88e12c95fc19f719e06ca1e9eb20fdad68ef61a"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:49:10.689564601+00:00"},"epss":{"cve":"CVE-2026-74397","score":0.00129,"percentile":0.02523,"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).
