{"apiVersion":"1.0","identifier":"CVE-2026-74683","description":"In the Linux kernel, the following vulnerability has been resolved: Input: evdev - sanitize event type index when fetching event masks The user-supplied event type index passed to EVIOCGMASK / EVIOCSMASK ioctls is used to index the static counts array in evdev_get_mask_cnt() and client evmasks array in evdev_get_mask(). While the event type is architecturally bounded by EV_CNT, speculative execution may mispredict bounds checks and perform out-of-bounds loads. Sanitize the event type index in evdev_get_mask_cnt() branchlessly using array_index_mask_nospec(). This clamps the index to 0 for safe array access and forces the returned count to 0 speculatively when the index is out of bounds. We do not need additional array_index_nospec() calls in evdev_get_mask() because evdev_get_mask_cnt() speculatively forces the count (and resulting xfer_size) to 0 for out-of-bounds types, preventing any speculative memory access to client evmasks array.","publishedAt":"2026-08-22T16:16:42","lastModifiedAt":"2026-08-25T06:18:51","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-74683","cvssScore":null,"cvssVector":"Pending","epssProbability":0.0019,"riskScore":0,"affectedProduct":"linux","affectedVersions":"unknown","vulnerabilityType":"Kernel","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-74683","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-74683","en":"https://www.redsauce.net/en/cves/CVE-2026-74683","fr":"https://www.redsauce.net/fr/cves/CVE-2026-74683","pt":"https://www.redsauce.net/pt/cves/CVE-2026-74683","de":"https://www.redsauce.net/de/cves/CVE-2026-74683","sk":"https://www.redsauce.net/sk/cves/CVE-2026-74683","el":"https://www.redsauce.net/el/cves/CVE-2026-74683"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-74683"}}
