CVE-2026-74693

CVE-2026-74693 affects the Linux kernel 's Prestera network driver (net: prestera). The function prestera_fw_hdr_parse() reads the firmware header before verifying that the firmware image is long enough to contain it, resulting in an out-of-bounds read of the magic and version fields. The fix rej...

PT-2026-79698

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description An issue exists in the prestera fw hdr parse function where the firmware header is read before verifying if the firmware image actually contains that header. This occurs when the system...

CVE-2026-63964

The CVE-2026-63964 entry describes a Linux kernel vulnerability in usb: typec: ucsi: ccg where do_flash() searches firmware records for a ':' header. If a firmware image lacks ':' bytes, strnchr() returns NULL, and the loop uses p+1 and a large length, causing a crash. A root user could place a c...
