Name of the Vulnerable Software and Affected Versions:
Linux kernel versions prior to 6.6.61
Description:
A bug in the Linux kernel has been resolved, specifically in the RDMA/bnxt re module, which fixes a bug while setting up Level-2 PBL pages. This bug could lead to memory corruption when setting up Level-2 PBL pages for non-MR resources when
num pages is greater than 256K. The current logic assumes multiple pages, resulting in invalid memory access after 256K PBL entries in the PDE.Recommendations:
For Linux kernel versions prior to 6.6.61, update to version 6.6.61 or later to resolve the issue. As a temporary workaround, consider restricting access to the RDMA/bnxt re module until a patch is available. Avoid using the
num pages variable with values greater than 256K in the affected API endpoints until the issue is resolved.Exploit
