CVE-2026-45952

The CVE-2026-45952 issue affects the Linux kernel fbnic driver. It concerns MTU changes when an XDP program is attached: increasing MTU beyond the hardware threshold can cause fragmentation across multiple buffers, and the driver will drop all multi-fragment frames for single-buffer XDP. This can...

CVE-2026-45844

Summary: CVE-2026-45844 affects the Linux kernel netfilter arp_tables on IEEE1394 (FireWire) interfaces. The vulnerability arises because arp_packet_match() unconditionally parses the ARP payload assuming both source and target hardware addresses exist, while IPv4-over-IEEE1394 ARP omits the targ...
