EUVD-2026-76323
In the Linux kernel, the following vulnerability has been resolved: net: tun: bound receive headroom tungetuser uses tun-align both as skb headroom and when choosing how much packet data to keep linear. OVS can propagate an oversized headroom request from another port to TUN or TAP. When align is...
CVE-2026-80978

CVE-2026-80978
CVE-2026-80978 affects the Linux kernel networking subsystem, specifically the IP tunnel devices. When a local attacker stacks user-created IP tunnel devices, the derived needed_headroom can exceed the 16-bit skb header offset range, causing those offsets to wrap during skb head expansion. The fi...

CVE-2026-74668
CVE-2026-74668 affects the Linux kernel's packet socket subsystem in the TX_RING send path. The function tpacket_snd() reads dev->hard_header_len independently for skb allocation and header construction in tpacket_fill_skb(). A concurrent netdevice reconfiguration can cause the reserved headro...

PT-2024-7732
Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description The vulnerability is related to the ip tunnel infrastructure in the Linux kernel, which can cause dev-needed headroom to increment indefinitely. This issue can lead to a use-after-free...
kernel: xdp_umem_reg in net/xdp/xdp_umem.c has an out-of-bounds write which could result in crash and data coruption
An out-of-bounds OOB memory access flaw was found in the Network XDP the eXpress Data Path module in the Linux kernel's xdpumemreg function in net/xdp/xdpumem.c. When a user with special user privilege of CAPNETADMIN or root calls setsockopt to register umem ring on XDP socket, passing the headro...
