A flaw was found in the bnx2x component of the Linux kernel. This flaw occurs due to a double free vulnerability within the bnx2x_init_firmware() function's error handling path. Memory pointers are freed without being set to NULL, allowing the bnx2x_release_firmware() cleanup function to attempt freeing the same memory a second time. This issue could lead to system instability, a denial of service (DoS), or potentially arbitrary code execution.
