What is CVE-2024-57994?

This vulnerability in the Linux kernel impacts the ptr_ring functionality, which could potentially lead to unintended interruptions during operations. A recent change ensures hard interrupts are not masked during ptr_ring resizing, promoting system stability and reliability. By modifying the ptr_ring_resize_multiple() function to be safe against bottom halves only, and renaming it to ptr_ring_resize_multiple_bh(), the kernel maintains improved performance and system integrity, significantly reducing the risk of unexpected behaviors.
