NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-modules package and not the kernel-modules package as distributed by RHEL. See How to fix? for RHEL:9 relevant fixed versions and status.

In the Linux kernel, the following vulnerability has been resolved:

RDMA/qedr: Fix potential memory leak in __qedr_alloc_mr()

__qedr_alloc_mr() allocates a memory chunk for "mr->info.pbl_table" with init_mr_info(). When rdma_alloc_tid() and rdma_register_tid() fail, "mr" is released while "mr->info.pbl_table" is not released, which will lead to a memory leak.

We should release the "mr->info.pbl_table" with qedr_free_pbl() when error occurs to fix the memory leak.
