SUSE 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-2026-64046

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...
