CVE-2026-53031
In the Linux kernel, the following vulnerability has been resolved: bpf: Validate node_id in arena_alloc_pages() arena_alloc_pages() accepts a plain int node_id and forwards it through the entire allocation chain without any bounds checking.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.13%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
