This CVE details a vulnerability in the Linux kernel’s RDMA/bnxt_re driver related to Level-2 PBL page setup. When handling a specific scenario with a high number of pages (greater than 256K), the driver logic assumes multiple pages while there’s actually a single PDE page address. This mismatch leads to invalid memory access, potentially causing crashes or code execution.
