CVE-2026-64548

In the Linux kernel, the following vulnerability has been resolved: bpf, sockmap: reject overflowing copy + len in bpfmsgpushdata When the scatterlist ring is full or nearly full, bpfmsgpushdata enters a copy fallback path and computes copy + len for the page allocation size. Since len comes from...

CVE-2026-64548

The CVE-2026-64548 vulnerability affects the Linux kernel’s BPF/sockmap path. A truncation can occur in bpf_msg_push_data when the scatterlist ring is full or nearly full: len (from BPF ARG_ANYTHING) and copy size are both u32, and the code path uses copy + len to compute a page allocation. An at...

CVE-2026-64025

A flaw was found in the Linux kernel's BPF Berkeley Packet Filter sockmap component when used with kernel TLS kTLS receive. A race condition exists where skpsockverdictdataready can improperly interact with the kTLS receive process. This can lead to a use-after-free vulnerability, potentially...

CVE-2026-63926

A flaw was found in the Linux kernel's sockmap feature. When the bpfmsgpushdata function processes data, it incorrectly calculates the offset for data fragments, leading to an inconsistent memory arrangement. This issue could potentially allow a local attacker to cause data corruption or system...

CVE-2026-63926

CVE-2026-63926 affects the Linux kernel where the bpf sockmap data path (bpf_msg_push_data) mishandles the tail fragment offset when inserting data into a scatterlist. The issue occurs when splitting a scatterlist entry into left/right fragments; the right fragment offset was advanced using a mes...
