NVD Description
Note: Versions mentioned in the description apply only to the upstream perf package and not the perf package as distributed by RHEL.
See How to fix? for RHEL:8 relevant fixed versions and status.
In the Linux kernel, the following vulnerability has been resolved:
xprtrdma: fix pointer derefs in error cases of rpcrdma_ep_create
If there are failures then we must not leave the non-NULL pointers with
the error value, otherwise rpcrdma_ep_destroy gets confused and tries
free them, resulting in an Oops.
