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"
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.
Affected configurations
• linux linux kernel (>= 4.9 < 5.10.137)
• linux linux kernel (>= 5.11 < 5.15.61)
• linux linux kernel (>= 5.16 < 5.18.18)
• linux linux kernel (>= 5.19 < 5.19.2)
