CVE-2026-80841 net/packet: defer vmalloc TX_RING free until skbs finish

In the Linux kernel, the following vulnerability has been resolved: net/packet: defer vmalloc TXRING free until skbs finish AFPACKET TXRING skbs keep a raw pointer to their ring frame. The skb page references preserve page-backed ring blocks after pgvec is freed, but they do not preserve a vmallo...

CVE-2026-80841

CVE-2026-80841 is a use-after-free in the Linux kernel's AF_PACKET TX_RING subsystem. AF_PACKET TX_RING skbs hold a raw pointer to their ring frame; while page references preserve page-backed ring blocks after the ring vector is freed, they do not preserve a vmalloc mapping. This means a late skb...

CVE-2026-74560

CVE-2026-74560 concerns the Linux kernel XDP stack, specifically the xsk_drop_skb() path for AF_XDP multi-buffer transmissions. The issue arises when an overflow path partially builds multi-fragment skbs, causing buffer addresses to be published incorrectly and leaving buffers untracked in usersp...

EUVD-2026-59625

In the Linux kernel, the following vulnerability has been resolved: xsk: fix buffer leak in xskdropskb for AFXDP multi-buffer Tx This patch is inspired by the check1 from sashiko. It says when overflow happens, the address of cq to be published is invalid. Actually the severer thing is the whole...

CVE-2026-23048

The CVE-2026-23048 entry describes a Linux kernel UDP path issue: the standard UDP receive path did not use skb->destructor, while the skmsg layer did via skb_set_owner_sk_safe() in udp_read_skb(), leading to a DEBUG_NET_WARN_ON_ONCE(skb->destructor) in skb_attempt_defer_free(). The documen...
