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

There is no network-facing consumer of this interface.\nAC:L - Triggering is fully deterministic \u2014 the attacker simply passes a crafted vec_len (e.g. 2^61, or 0x1_0000_0001) in the pm_scan_arg struct; no race, timing window, or uncontrollable memory state is involved, and the attacker shapes both the slab allocation size and the overflow contents via its own VMA layout.\nPR:L - Any unprivileged local user can open /proc/self/pagemap, since proc_mem_open(PTRACE_MODE_READ) always permits self-access and no capability is checked on the PAGEMAP_SCAN path. CONFIG_PROC_PAGE_MONITOR is enabled by default.\nUI:N - The attacking process performs the entire sequence itself \u2014 open its own pagemap file and issue one ioctl. No victim action or cooperation is needed.\nS:U - The corruption stays within the kernel of the affected system and the calling process\u0027s own address space; no VM, IOMMU, or other security-authority boundary is crossed.\nC:H - The defeated access_ok range check plus the resulting unbounded slab out-of-bounds write past a 24-byte kmalloc object lets an attacker corrupt adjacent slab objects (pointers, lengths, credentials), a classic heap-overflow primitive readily leveraged for arbitrary kernel memory disclosure.\nI:H - The vec_buf_len underflow in pagemap_scan_push_range yields a repeatable out-of-bounds heap write with partially attacker-shaped 24-byte payloads, giving an arbitrary-write primitive suitable for control-flow hijack and privilege escalation.\nA:H - The same input path produces an immediate kernel oops by dereferencing ZERO_SIZE_PTR (write at address 0x10) when kmalloc_array(0, 24) is used, and the slab overflow reliably panics the kernel on any hardened/allocator-checked configuration."
