CVE-2026-74457

A flaw was found in the Linux kernel's peakusb module. 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...

CVE-2026-74455

A flaw was found in the Linux kernel's peakusb Controller Area Network CAN driver. This vulnerability arises from insufficient validation of uCAN receive record lengths when processing data from a Universal Serial Bus USB receive buffer. A local attacker could potentially exploit this by sending...
