{"apiVersion":"1.0","identifier":"CVE-2026-74497","description":"In the Linux kernel, the following vulnerability has been resolved: ALSA: usb-audio: Clamp frame size in implicit-feedback mode snd_usb_handle_sync_urb() scales received sync packet sizes by the sender-s stride and stores the result directly in out_packet->packet_size[i]. If a connected USB device sends an oversized sync packet, this frame count can exceed ep->maxframesize. The un-clamped frame count then propagates to the playback endpoint queue, potentially driving packet transfers beyond the endpoint-s hardware frame limits. Cap the calculated frame count against ep->maxframesize in snd_usb_handle_sync_urb() to prevent oversized packets from entering the playback queue.","publishedAt":"2026-08-15T13:17:54","lastModifiedAt":"2026-08-19T17:21:06","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-74497","cvssScore":8.4,"cvssVector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","epssProbability":0.00142,"riskScore":0.85,"affectedProduct":"Linux kernel","affectedVersions":"unknown","vulnerabilityType":"Kernel","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-74497","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-74497","en":"https://www.redsauce.net/en/cves/CVE-2026-74497","fr":"https://www.redsauce.net/fr/cves/CVE-2026-74497","pt":"https://www.redsauce.net/pt/cves/CVE-2026-74497","de":"https://www.redsauce.net/de/cves/CVE-2026-74497","sk":"https://www.redsauce.net/sk/cves/CVE-2026-74497","el":"https://www.redsauce.net/el/cves/CVE-2026-74497"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-74497"}}
