Summaryinfo

A vulnerability identified as problematic has been detected in Linux Kernel up to 6.11.9. This affects the function pagemap_scan_get_args. The manipulation of the argument vec_len leads to integer overflow. This vulnerability is uniquely identified as CVE-2024-53107. No exploit exists. You should upgrade the affected component.

Detailsinfo

A vulnerability was found in Linux Kernel up to 6.11.9 and classified as problematic. This issue affects the function pagemap_scan_get_args. The manipulation of the argument vec_len with an unknown input leads to a integer overflow vulnerability. Using CWE to declare the problem leads to CWE-190. The product performs a calculation that can produce an integer overflow or wraparound, when the logic assumes that the resulting value will always be larger than the original value. This can introduce other weaknesses when the calculation is used for resource management or execution control. The impact remains unknown. The summary by CVE is:

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.

It is possible to read the advisory at git.kernel.org. The identification of this vulnerability is CVE-2024-53107 since 11/19/2024.
