CVE-2024-53174

  3. CVE-2024-53174
In the Linux kernel, the following vulnerability has been resolved: SUNRPC: make sure cache entry active before cache_show The function `c_show` was called with protection from RCU. This only ensures that `cp` will not be freed. Therefore, the reference count for `cp` can drop to zero, which will trigger a refcount use-after-free warning when `cache_get` is called. To resolve this issue, use `cache_get_rcu` to ensure that `cp` remains active. ------------[ cut here ]------------ refcount_t: addition on 0; use-after-free.
