{"apiVersion":"1.0","identifier":"CVE-2026-74451","description":"In the Linux kernel, the following vulnerability has been resolved: drm/panthor: validate firmware interface structure sizes iface_fw_to_cpu_addr() only checks that the firmware-provided MCU virtual address points inside the shared section. The returned pointer is later used as a full firmware interface structure, so accepting an address near the end of the shared section can still lead to out-of-bounds accesses. Pass the expected object size to iface_fw_to_cpu_addr() and reject ranges that do not fit entirely in the shared section.","publishedAt":"2026-08-15T13:17:49","lastModifiedAt":"2026-08-17T06:19:40","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-74451","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-2026-74451","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-74451","en":"https://www.redsauce.net/en/cves/CVE-2026-74451","fr":"https://www.redsauce.net/fr/cves/CVE-2026-74451","pt":"https://www.redsauce.net/pt/cves/CVE-2026-74451","de":"https://www.redsauce.net/de/cves/CVE-2026-74451","sk":"https://www.redsauce.net/sk/cves/CVE-2026-74451","el":"https://www.redsauce.net/el/cves/CVE-2026-74451"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-74451"}}
