CVE-2025-68234 is a high-severity vulnerability rated 7.8/10 on the CVSS scale. 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. EPSS estimates a 0.15% chance of exploitation in the next 30 days.
