Description OSIDB Bzimport 2025-12-16 15:02:39 UTC
In the Linux kernel, the following vulnerability has been resolved:

io_uring/cmd_net: fix wrong argument types for skb_queue_splice()

If timestamp retriving needs to be retried and the local list of
SKB's already has entries, then it's spliced back into the socket
queue. However, the arguments for the splice helper are transposed,
causing exactly the wrong direction of splicing into the on-stack
list. Fix that up.
