CVE-2026-46433

CVE-2026-46433 affects lldpd (LLDP implementation). Prior to version 1.0.22, lldpd_decode() incorrectly shifts frame payload when removing 802.1Q VLAN tags, using a length calculation that causes a 4-byte heap OOB read if the frame size equals the interface MTU. This vulnerability is fixed in ver...

EUVD-2026-27597

In the Linux kernel, the following vulnerability has been resolved: xsk: tighten UMEM headroom validation to account for tailroom and min frame The current headroom validation in xdpumemreg could leave us with insufficient space dedicated to even receive minimum-sized ethernet frame. Furthermore ...

CVE-2026-43093

CVE-2026-43093 is a Linux kernel issue in the xsk (AF_XDP) subsystem where headroom validation for UMEM was tightened in xdp_umem_reg(), addressing potential memory corruption of skb_shared_info and insufficient space for minimum-sized Ethernet frames. The fix accounts for 128-byte alignment as a...
