CVE-2024-53174 is a use-after-free vulnerability in the Linux kernel's SUNRPC subsystem. The issue arises because the function c_show was called with RCU protection that only prevents freeing the pointer cp, but does not prevent its reference count from dropping to zero. This can lead to a refcount use-after-free warning when cache_get is called. The vulnerability has been resolved by using cache_get_rcu to ensure the cache entry remains active during the operation.
