CVE-2022-50138 Information

Jun 19, 2025 cve

Description

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\nis 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.
