CVE-2022-50042 is a medium-severity vulnerability rated 5.5/10 on the CVSS scale. 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.. EPSS estimates a 0.21% chance of exploitation in the next 30 days.
