- net: genl: fix error path memory leak in policy dumping
- Details
-
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.
netlinkpolicydumpaddpolicy() itself also needs fixing as it currently gives up on error without recording the allocated pointer in the pstate pointer.
