high Tenable Self-Hosted Container Security Plugin ID 457277

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - In the Linux kernel, the following vulnerability has been resolved: vsock/virtio: fix potential unbounded
 skb queue virtio_transport_inc_rx_pkt() checks vvs->rx_bytes + len > vvs->buf_alloc.
 virtio_transport_recv_enqueue() skips coalescing for packets with VIRTIO_VSOCK_SEQ_EOM. If fed with
 packets with len == 0 and VIRTIO_VSOCK_SEQ_EOM, a very large number of packets can be queued because
 vvs->rx_bytes stays at 0. Fix this by estimating the skb metadata size: (Number of skbs in the queue) *
 SKB_TRUESIZE(0) (CVE-2026-53132)

Solution

Update the linux library and its related packages to version 6.12.94-1 or later.
