In the Linux kernel, the following vulnerability has been resolved: net/packet: fix TOCTOU race on mmap'd vnethdr in tpacketsnd In tpacketsnd, when PACKETVNETHDR is enabled, vnethdr points directly into the mmap'd TX ring buffer shared with userspace. The kernel validates the header via...

The vulnerabilities of the functions vhost_vsock_alloc_pkt() (drivers/vhost/vsock.c) and virtio_transport_free_pkt() (net/vmw_vsock/virtio_transport_common.c) in the Linux operating system’s IoTLB generic implementation for vhost and vringh kernels allow a hacker to induce a service failure.

The vulnerabilities of the functions vhostvsockallocpkt drivers/vhost/vsock.c and virtiotransportfreepkt net/vmwvsock/virtiotransportcommon.c in the Linux operating system’s IoTLB implementation are related to errors in resource allocation of large sizes. Exploiting these vulnerabilities can allo...

CVE-2026-31469

A flaw was found in the Linux kernel's virtionet driver. A local user can trigger a Use-After-Free UAF vulnerability by configuring the driver with specific network settings and then destroying the network namespace while data packets are still being transmitted. This premature freeing of network...
