CVE-2026-74457Source published Source updated
In the Linux kernel, the following vulnerability has been resolved: can: peak_usb: add bounds check for USB channel index The channel control index ctrl_idx is derived from rx->len which comes directly from a device USB payload. The mask 0x0f allows values 0-15, but the array size of usb_if->dev[] is only 2. Values 2-15 cause heap out-of-bounds read, eventually causing kernel panic in the IRQ context. Add bounds checking for ctrl_idx before the array access in both pcan_usb_pro_handle_canmsg() and pcan_usb_pro_handle_error(). A malicious USB device could send a specially crafted payload, leading to a heap out-of-bounds read. This vulnerability can cause a kernel panic, resulting in a Denial of Service (DoS) for the affected system. Red Hat severity: Moderate — CVSS 5.5…
