In the Linux kernel, the following vulnerability has been resolved: bpf: Skip unsettled links in link iterator bpflinkprime inserts a link into linkidr before anoninodegetfile succeeds and before bpflinksettle publishes the ID in link-id. bpflinkbyid treats such an ID-zero link as unsettled, but...

DEBIAN-CVE-2026-98383

In the Linux kernel, the following vulnerability has been resolved: bpf: Disallow bpfskbpulldata for LWTSEG6LOCAL An LWTSEG6LOCAL program can invalidate its cached SRH with bpflwtseg6adjustsrh and then call bpfskbpulldata. The latter may reallocate skb-head, leaving the per-CPU SRH pointer...

AZL-106902 CVE-2026-98382 affecting package kernel 6.6.157.1-1

In the Linux kernel, the following vulnerability has been resolved: bpf: Reject dev-bound-only programs on other devices bpfoffloaddevmatch falls back to comparing offdev pointers after an exact netdev mismatch. Bound-only programs normally have NULL offdevs, so unrelated netdevs compare equal. A...

AZL-106914 CVE-2026-98384 affecting package kernel 6.6.157.1-1

In the Linux kernel, the following vulnerability has been resolved: bpf: Fix out-of-bounds read of skprotocol in bpfsockdestroy skprotocol lives in struct sock, not in struct sockcommon. A timewait or request sock handed to bpfsockdestroy by the tcp iterator is neither, so reading sk-skprotocol...

CVE-2026-98384

The Linux kernel contains an out-of-bounds read vulnerability in the bpf subsystem within the bpf_sock_destroy() function. The issue arises because the code attempts to read sk_protocol from a sock structure; however, for timewait or request sockets handed to the function by the tcp iterator, thi...

CVE-2026-98383

The Linux kernel contains a vulnerability where an LWT_SEG6LOCAL program can invalidate its cached SRH using bpf_lwt_seg6_adjust_srh() and subsequently call bpf_skb_pull_data(). This sequence can cause skb->head to be reallocated, resulting in a dangling per-CPU SRH pointer . Subsequent post-p...

Bound-only programs normally have NULL offdevs, so unrelated netdevs compare equal. A...

CVE-2026-98382

The Linux kernel contains a vulnerability where bound-only BPF programs can incorrectly match sibling ports due to a fallback mechanism in __bpf_offload_dev_match(). Because these programs typically have NULL offdevs , unrelated netdevs can compare as equal on offload-registered netdevs. An attac...
