A security advisory from Red Hat addresses multiple vulnerabilities in the Linux kernel packages for Red Hat Enterprise Linux 10 and related products. The update fixes issues including race conditions, buffer overflows, use-after-free, and validation errors across various kernel subsystems such as NFS, vsock/virtio, IPv6, ALSA audio, and others. The advisory rates the overall impact as moderate and requires a system reboot after applying the update.

Multiple security vulnerabilities have been identified and fixed in the Linux kernel packages used by Red Hat Enterprise Linux 10 and related distributions. These include race conditions, buffer overflows, and improper bounds checking in various kernel subsystems such as NFS, vsock/virtio, memory management, ALSA audio, and WiFi. The update addresses these issues to improve system security and stability. A system reboot is required after applying the update for changes to take effect.

In the Linux kernel, the following vulnerability has been resolved: vsock/virtio: Validate length in packet header before skb_put() When receiving a vsock packet in the guest, only the virtqueue buffer size is validated prior to virtio_vsock_skb_rx_put(). Unfortunately, virtio_vsock_skb_rx_put() uses the length from the packet header as the length argument to skb_put(), potentially resulting in SKB overflow if the host has gone wonky. Validate the length as advertised by the packet header before calling virtio_vsock_skb_rx_put().
