Two vulnerabilities have been identified in Linux Kernel, which could be exploited by local attackers to cause a denial of service or disclose sensitive information.
The first issue is due to an error in the "lease_init()" [fs/locks.c] function that incorrectly frees unallocated memory when handling an invalid "arg" argument, which could be exploited by malicious users to crash a vulnerable system.
The second issue is due to an uninitialised return value in "__setlease()", which could cause a slab leak.
