Memory Allocation Vulnerability in Linux Kernel

CVE-2024-50209

What is CVE-2024-50209?

In the Linux kernel, a vulnerability has been identified related to the RDMA/bnxt_re driver. The function __alloc_pbl() may return an error if memory allocation fails, but the driver lacks an adequate check for this failure in one of its instances. This oversight could potentially result in instability and unexpected behavior within systems relying on this driver, particularly affecting operations that depend on successful memory allocation. Addressing this gap is essential for maintaining reliable and secure kernel performance.
