CVE-2026-98591
In the Linux kernel, the following vulnerability has been resolved: bpf: Fix bounds check for skb-backed dynptrs The skbpointeriflinear function checks whether a memory region of length len starting at offset off into the skb is in the linear area, and returns a pointer to the region if so. The...

CVE-2026-98591
The Linux kernel contains a vulnerability in the skb_pointer_if_linear() function used by skb-backed BPF dynptr code. The root cause is an unsigned subtraction underflow occurring between skb_headlen and the off parameter. This flaw allows the bounds check to spuriously pass, potentially generati...

SUSE CVE-2026-74590
In the Linux kernel, the following vulnerability has been resolved: fsverity: Fix bpfgetfsveritydigest dynptr assumptions The BPF verifier and the dynptr abstraction ensure that the memory space referenced by a dynptr remains valid. They do not, however, provide any guarantee that the contents of...

CVE-2026-74590
CVE-2026-74590 is a race condition in the Linux kernel's fsverity subsystem, specifically in the bpf_get_fsverity_digest() function. The BPF verifier and dynptr abstraction guarantee memory validity but not content stability; kfuncs must remain memory-safe under concurrent modifications. This fun...
