{"apiVersion":"1.0","identifier":"CVE-2026-74355","description":"In the Linux kernel, the following vulnerability has been resolved: iommu/vt-d: Fix RB-tree corruption in probe error path The info->node RB-tree member is zero-initialized via kzalloc. If a device does not support ATS, the device_rbtree_insert() call is skipped. If a subsequent probe step fails, the error path jumps to device_rbtree_remove(), which misinterprets the zeroed node as a tree root and corrupts the device RB-tree. Fix this by explicitly initializing the RB-node as empty using RB_CLEAR_NODE() during initialization and guarding the removal with RB_EMPTY_NODE().","publishedAt":"2026-08-15T06:22:36","lastModifiedAt":"2026-08-17T06:19:30","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-74355","cvssScore":8.2,"cvssVector":"CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:H","epssProbability":0.00132,"riskScore":0.83,"affectedProduct":"linux","affectedVersions":"unknown","vulnerabilityType":"Kernel","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-74355","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-74355","en":"https://www.redsauce.net/en/cves/CVE-2026-74355","fr":"https://www.redsauce.net/fr/cves/CVE-2026-74355","pt":"https://www.redsauce.net/pt/cves/CVE-2026-74355","de":"https://www.redsauce.net/de/cves/CVE-2026-74355","sk":"https://www.redsauce.net/sk/cves/CVE-2026-74355","el":"https://www.redsauce.net/el/cves/CVE-2026-74355"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-74355"}}
