- Summary
- CVE-2024-50169 affecting package kernel for versions less than 6.6.64.2-1
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
vsock: Update rx_bytes on read_skb()
Make sure virtio_transport_inc_rx_pkt() and virtio_transport_dec_rx_pkt() calls are balanced (i.e. virtio_vsock_sock::rx_bytes doesn't lie) after vsock_transport::read_skb().
While here, also inform the peer that we've freed up space and it has more credit.
Failing to update rx_bytes after packet is dequeued leads to a warning on SOCK_STREAM recv():
[ 233.396654] rx_queue is empty, but rx_bytes is non-zero [ 233.396702] WARNING: CPU: 11 PID: 40601 at net/vmw_vsock/virtio_transport_common.c:589
