CVE-2026-72408

Summary of the CVE-2026-72408 vulnerability (Linux kernel): The issue, in geneve GRO handling, arises when geneve_gro_complete() processes a GRO hint unconditionally while geneve_gro_receive() may honor the hint only if gs->gro_hint is enabled. This mismatch allowed an attacker-supplied GRO hi...

CVE-2026-72407

The CVE describes a Linux kernel vulnerability in geneve GRO handling where geneve_gro_complete() could derive a dispatch offset from stale or conflicting state (gs->gro_hint) vs the actual inner header parsed by geneve_gro_receive(), potentially leading to out-of-bounds processing. The fix en...

CVE-2026-68142

A flaw was found in the geneve component of the Linux kernel. A local attacker, with CAPNETADMIN privileges in a specific network namespace, could bypass intended permission checks. This allows them to modify the configuration of a geneve network device in a different network namespace, potential...

CVE-2026-68299

A flaw was found in the vmxnet3 virtual network device driver within the Linux kernel. When processing Geneve-encapsulated packets, the vmxnet3gethdrlen function can incorrectly interpret header information, leading to a mismatch between expected and actual packet protocols or IP versions. This c...
