Vulnerability from github
In the Linux kernel, the following vulnerability has been resolved:
net: microchip: vcap api: Fix possible memory leak for vcap_dup_rule()
Inject fault When select CONFIG_VCAP_KUNIT_TEST, the below memory leak occurs. If kzalloc() for duprule succeeds, but the following kmemdup() fails, the duprule, ckf and caf memory will be leaked. So kfree them in the error path.
