{"id":"AZL-96488","summary":"CVE-2026-74497 affecting package kernel 6.6.150.1-1","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nALSA: usb-audio: Clamp frame size in implicit-feedback mode\n\nsnd_usb_handle_sync_urb() scales received sync packet sizes by the sender's\nstride and stores the result directly in out_packet-\u003epacket_size[i]. If a\nconnected USB device sends an oversized sync packet, this frame count can\nexceed ep-\u003emaxframesize.\n\nThe un-clamped frame count then propagates to the playback endpoint queue,\npotentially driving packet transfers beyond the endpoint's hardware frame\nlimits.\n\nCap the calculated frame count against ep-\u003emaxframesize in\nsnd_usb_handle_sync_urb() to prevent oversized packets from entering the\nplayback queue.","modified":"2026-08-30T05:26:50Z","published":"2026-08-15T13:17:54Z","upstream":["CVE-2026-74497"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-74497"}],"affected":[{"package":{"name":"kernel","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/kernel"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"6.6.150.1-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-96488.json"}}],"schema_version":"1.9.0"}
