CVE-2026-23397

CVE-2026-23397 affects the Linux kernel nfnetlink_osf fingerprint matching. The issue arises when parsing TCP option fingerprints: add-time checks for option lengths are insufficient, allowing a zero-length option to bypass bounds checks and potentially trigger a fault in nf_osf_match_one() (kern...

CVE-2026-23298

A flaw was found in the Linux kernel's CAN Controller Area Network ucan driver. This vulnerability allows a connected ucan device to send a message with a zero-length field. Such a message can trigger an infinite loop within the driver, causing the system to hang. This ultimately leads to a denia...
