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.

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."

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
