CVE-2025-22057 is a medium-severity vulnerability in the Linux kernel related to improper handling of cached destination (dst) counters in the network stack. The issue arises when the kernel attempts to decrement cached dst counters during dst_release, particularly when CONFIG_DST_CACHE is enabled and Open vSwitch (OvS) tunnels are used. This can lead to a kernel paging request error and potential denial of service due to kernel crashes.
