CVE-2026-100236

A flaw was found in the DPDK GSO library.

Published Oct 14, 2026 · updated Oct 14, 2026 · Red Hat Fast Datapath for RHEL 10

A flaw was found in the DPDK GSO library. When software GSO copies packet headers into a new mbuf, it does not check that the header fits in the source first segment or in the destination buffer, and a header longer than the configured GSO segment size can underflow the payload-size calculation. A remote or guest-supplied packet processed with software GSO can trigger an out-of-bounds read or write.
