Descriptions
In the Linux kernel, the following vulnerability has been resolved: net: genl: fix error path memory leak in policy dumping If construction of the array of policies fails when recording
non-first policy we need to unwind. netlink_policy_dump_add_policy() itself also needs fixing as
it currently gives up on error without recording the allocated
pointer in the pstate pointer.
A flaw was found in the netlink driver in the Linux kernel. A memory leak can occur when allocated memory is not released in certain error cases, potentially impacting system performance and resulting in a denial of service.
