CVE-2026-64046

A flaw was found in the Linux kernel's network Transport Layer Security TLS subsystem. An issue in how scatterlist entries are chained could lead to illegal input being provided to cryptographic operations. This could potentially affect the integrity of TLS communications...

CVE-2026-63926

In the Linux kernel, the following vulnerability has been resolved: bpf: sockmap: fix tail fragment offset in bpfmsgpushdata When bpfmsgpushdata inserts data in the middle of a scatterlist entry, it splits the original entry into a left fragment and a right fragment. The right fragment offset is...

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...

CVE-2026-63872

CVE-2026-63872 affects the Linux kernel esp path (esp4/esp6) where, on skb_to_sgvec failure during esp_output_tail, old skb page fragments are not unrefsed when a second scatterlist build fails. The root cause: a page frag reference leak in the source scatterlist if the destination sgvec creation...
