CVE-2022-48874

A vulnerability was found in the Linux kernel's fastrpc.c driver. A race condition is possible between the time that the fastrpc_map_lookup() function unlocks a mutex and the reference count is increased by the fastrpc_map_get() function in the fastrpc_map_find() function. This race condition could result in a use-after-free situation, where a mapping object is freed while still being referenced by something else. This issue could lead to memory corruption or unpredictable behavior.
