CVE-2026-74665

A flaw was found in the Linux kernel. Incorrect length accounting for skb socket buffer fragments after an eXpress Data Path XDP program adjusts the fragment area can lead to an out-of-bounds read. This allows an attacker to potentially disclose sensitive kernel pointers and corrupt user-space...

CVE-2026-74627

A flaw was found in the Linux kernel's net: devmem component. This vulnerability occurs when netiov and page-backed fragments are improperly mixed within a single skb socket buffer in the zerocopyfillskbfromdevmem function. This improper handling can lead to a system crash, resulting in a Denial ...

CVE-2026-74612

A flaw was found in the Linux kernel's veth component. A remote attacker could exploit incorrect packet buffer skb length accounting after an eXpress Data Path XDP fragment adjustment. This could lead to the disclosure of sensitive kernel memory information to userspace and corruption or truncati...
