CVE-2024-53107 fs/proc/task_mmu: prevent integer overflow in pagemap_scan_get_args()

What is CVE-2024-53107?

CVE-2024-53107 is a high-severity vulnerability in Linux kernel, published on 2 Dec 2024. It can only be exploited from the same machine or local network, with no action from the victim.

Official description

In the Linux kernel, the following vulnerability has been resolved:

fs/proc/task_mmu: prevent integer overflow in pagemap_scan_get_args()

The "arg->vec_len" variable is a u64 that comes from the user at the start of the function. The "arg->vec_len * sizeof(struct page_region))" multiplication can lead to integer wrapping. Use size_mul() to avoid that.

Also the size_add/mul() functions work on unsigned long so for 32bit systems we need to ensure that "arg->vec_len" fits in an unsigned long.

Weakness: CWE-190
