{"apiVersion":"1.0","identifier":"CVE-2026-74397","description":"In the Linux kernel, the following vulnerability has been resolved: IB/mlx5: Fix transport-domain rollback and initialize lb mutex earlier mlx5_ib_alloc_transport_domain() allocates a transport domain and then may fail in mlx5_ib_enable_lb(). In that case, the allocated TD is leaked. Fix this by deallocating the TD when mlx5_ib_enable_lb() returns an error. Also return 0 explicitly in the no-loopback-capability success branch, and move dev->lb.mutex initialization to mlx5_ib_stage_init_init().","publishedAt":"2026-08-15T06:22:41","lastModifiedAt":"2026-08-17T06:19:34","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-74397","cvssScore":7.8,"cvssVector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","epssProbability":0.00129,"riskScore":0.79,"affectedProduct":"Linux kernel","affectedVersions":"unknown","vulnerabilityType":"Kernel","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-74397","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-74397","en":"https://www.redsauce.net/en/cves/CVE-2026-74397","fr":"https://www.redsauce.net/fr/cves/CVE-2026-74397","pt":"https://www.redsauce.net/pt/cves/CVE-2026-74397","de":"https://www.redsauce.net/de/cves/CVE-2026-74397","sk":"https://www.redsauce.net/sk/cves/CVE-2026-74397","el":"https://www.redsauce.net/el/cves/CVE-2026-74397"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-74397"}}
