CVE-2026-74742

A flaw was found in the Linux kernel's veth component. In a multi-queue setup without an eXpress Data Path XDP program attached, the vethpoll function incorrectly derives the index of the peer transmit TX queue to wake. This can cause a TX queue to stop indefinitely if it becomes full, as the...

SUSE CVE-2026-74317

In the Linux kernel, the following vulnerability has been resolved: ixgbe: do not configure xps for XDP queues netifsetxpsqueue should not be called for an XDP Tx queue, since such queues are not netdev-exposed. On systems with number of CPUs =64, on E610 adapter, netdev is configured with maximu...

SUSE CVE-2026-74684

In the Linux kernel, the following vulnerability has been resolved: net: tap: set skb-dev before parsing virtio net header in tapgetuserxdp The commit 4f61f133f354 "net: tap: NULL pointer derefence in devparseheaderprotocol when skb-dev is null" fixed a crash in tapgetuser by assigning skb-dev...

CVE-2026-74684

A flaw was found in the Linux kernel's net: tap module. A NULL pointer dereference can occur in the tapgetuserxdp function when processing an XDP buffer with a GSO virtio-net header and a zero protocol. This can be triggered by a malicious guest in a virtualized environment, leading to a system...

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-2026-74616

A flaw was found in the Linux kernel's XDP eXpress Data Path component. When XDP frames are cloned, a specially crafted frame can cause the skbsharedinfo structure to overwrite live packet data. This improper handling of memory during frame cloning can lead to corruption of XDP return metadata,...

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...
