Description:
A vulnerability has been reported in the Linux Kernel, which potentially can be exploited by malicious, local users to cause a DoS (Denial of Service).
The vulnerability is caused due to a error within the "lease_init()" function in "fs/locks.c". This causes it to free memory that may not have been allocated using the "locks_alloc_lock()" function. This may cause the kernel to crash when the "fcntl_setlease()" function is called.
Note: A slab leak in "__setlease()" due to an uninitialised return value has also been reported.
