CVE-2024-53227

Summary

CVE-2024-53227 is a vulnerability affecting the Linux kernel that has been resolved. This issue involves a use-after-free error in the 'bfad_im_module_exit()' function of the 'bfa' driver. The error occurred due to a double release of resources, with the task 'modprobe/25303' allocating and then freeing memory that was later accessed by another part of the code. The vulnerability was discovered during a kernel address sanitizer (KASAN) scan, with the call trace indicating that the error occurred in the '__lock_acquire' function. To mitigate this issue, it is recommended not to call 'bfad_im_module_exit()' if 'bfad_im_module_init()' fails.
