Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> RDMA/qedr: Fix potential memory leak in __qedr_alloc_mr()<br /> <br /> __qedr_alloc_mr() allocates a memory chunk for "mr-&gt;info.pbl_table" with<br /> init_mr_info(). When rdma_alloc_tid() and rdma_register_tid() fail, "mr"<br /> is released while "mr-&gt;info.pbl_table" is not released, which will lead<br /> to a memory leak.<br /> <br /> We should release the "mr-&gt;info.pbl_table" with qedr_free_pbl() when error<br /> occurs to fix the memory leak.
