Overview
Affected versions of this package are vulnerable to Access Restriction Bypass via the mr_check_range function. An attacker can cause out-of-bounds read and write operations by crafting RDMA-Write or RDMA-Read requests with manipulated iova and length values that trigger integer overflow, resulting in kernel memory disclosure or corruption.
Note: The Linux kernel project assigns a CVE to every bug fix it ships, whether or not the bug has been shown to be exploitable. This advisory was generated from that process and has not been individually assessed for exploitability. See the kernel's CVE process documentation: https://github.com/torvalds/linux/blob/master/Documentation/process/cve.rst
