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.

We should release the "mr->info.pbl_table" with qedr_free_pbl() when error
occurs to fix the memory leak.
A flaw was found in the qedr module in the Linux kernel. A missing release of allocated memory when an error occurs will cause a memory leak, potentially impacting system performance and resulting in a denial of service.
