{"apiVersion":"1.0","identifier":"CVE-2026-74396","description":"In the Linux kernel, the following vulnerability has been resolved: RDMA/mlx5: Fix UMR XLT cleanup on ODP populate failure mlx5r_umr_update_xlt() allocates and DMA maps an XLT buffer with mlx5r_umr_create_xlt(). The buffer is released by the common cleanup path through mlx5r_umr_unmap_free_xlt(). After mlx5_odp_populate_xlt() became fallible, its error path returned directly and skipped that cleanup. This leaks the XLT DMA mapping and buffer. If the emergency XLT page was used, it also leaves xlt_emergency_page_mutex locked. Break out of the loop so execution falls through the existing cleanup path.","publishedAt":"2026-08-15T06:22:41","lastModifiedAt":"2026-08-17T06:19:34","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-74396","cvssScore":7.5,"cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","epssProbability":0.00512,"riskScore":0.78,"affectedProduct":"Linux kernel","affectedVersions":"unknown","vulnerabilityType":"Kernel","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-74396","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-74396","en":"https://www.redsauce.net/en/cves/CVE-2026-74396","fr":"https://www.redsauce.net/fr/cves/CVE-2026-74396","pt":"https://www.redsauce.net/pt/cves/CVE-2026-74396","de":"https://www.redsauce.net/de/cves/CVE-2026-74396","sk":"https://www.redsauce.net/sk/cves/CVE-2026-74396","el":"https://www.redsauce.net/el/cves/CVE-2026-74396"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-74396"}}
