CVE-2022-50042 Information

Jun 19, 2025 cve

Description

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.
