Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> RDMA/bnxt_re: Fix a bug while setting up Level-2 PBL pages<br /> <br /> Avoid memory corruption while setting up Level-2 PBL pages for the non MR<br /> resources when num_pages &gt; 256K.<br /> <br /> There will be a single PDE page address (contiguous pages in the case of &gt;<br /> PAGE_SIZE), but, current logic assumes multiple pages, leading to invalid<br /> memory access after 256K PBL entries in the PDE.
