{"id":"AZL-96186","summary":"CVE-2026-74457 affecting package kernel 6.6.150.1-1","details":"In the Linux kernel, the following vulnerability has been resolved:\n\ncan: peak_usb: add bounds check for USB channel index\n\nThe channel control index ctrl_idx is derived from rx-\u003elen which comes\ndirectly from a device USB payload. The mask 0x0f allows values 0-15, but\nthe array size of usb_if-\u003edev[] is only 2. Values 2-15 cause heap\nout-of-bounds read, eventually causing kernel panic in the IRQ context.\n\nAdd bounds checking for ctrl_idx before the array access in both\npcan_usb_pro_handle_canmsg() and pcan_usb_pro_handle_error().","modified":"2026-08-30T05:26:50Z","published":"2026-08-15T13:17:50Z","upstream":["CVE-2026-74457"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-74457"}],"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-96186.json"}}],"schema_version":"1.9.0"}
