A vulnerability in the Linux kernel's mglru page table walker was fixed to address stale batch updates after memory control group (memcg) reparenting. The issue caused underestimation of page counts (nr_pages) in the MGLRU mechanism, leading to premature out-of-memory (OOM) conditions because memory reclamation was not triggered correctly. The fix involves checking the memcg state under RCU before flushing batch updates to ensure accurate page accounting during concurrent memcg reparenting.
