CVE-2026-53153 (GCVE-0-2026-53153)

Vulnerability from cvelistv5 – Published: 2026-06-25 08:38 – Updated: 2026-09-02 12:04

Title

mm/list_lru: drain before clearing xarray entry on reparent

Summary

In the Linux kernel, the following vulnerability has been resolved: mm/list_lru: drain before clearing xarray entry on reparent memcg_reparent_list_lrus() clears the dying memcg's xarray entry with xas_store(&xas, NULL) before reparenting its per-node lists into the parent. This opens a window where a concurrent list_lru_del() arriving for the dying memcg sees xa_load() == NULL, walks to the parent in lock_list_lru_of_memcg(), takes the parent's per-node lock, and calls list_del_init() on an item still physically linked on the dying memcg's list. If another in-flight thread holds the dying memcg's per-node lock at the same moment (another list_lru_del, or a list_lru_walk_one running an isolate callback), both threads modify ->next/->prev pointers on the same physical list under different locks. Adjacent items can corrupt each other's links. Fix it by reversing the order: reparent each per-node list and mark the child's list lru dead and then clear the xarray entry. Any concurrent list_lru op that finds the still-set xarray entry either takes the dying memcg's per-node lock (synchronizing with the drain) or sees LONG_MIN and walks to the parent, where the items now live.

This opens a window where a concurrent list_lru_del() arriving\nfor the dying memcg sees xa_load() == NULL, walks to the parent in\nlock_list_lru_of_memcg(), takes the parent\u0027s per-node lock, and calls\nlist_del_init() on an item still physically linked on the dying memcg\u0027s\nlist.\n\nIf another in-flight thread holds the dying memcg\u0027s per-node lock at the\nsame moment (another list_lru_del, or a list_lru_walk_one running an\nisolate callback), both threads modify -\u003enext/-\u003eprev pointers on the same\nphysical list under different locks.  Adjacent items can corrupt each\nother\u0027s links.\n\nFix it by reversing the order: reparent each per-node list and mark the\nchild\u0027s list lru dead and then clear the xarray entry.  Any concurrent\nlist_lru op that finds the still-set xarray entry either takes the dying\nmemcg\u0027s per-node lock (synchronizing with the drain) or sees LONG_MIN and\nwalks to the parent, where the items now live."

It is not directly reachable by unauthenticated network packets.\nAC:L - The issue is a race, but a local attacker with control of a delegated cgroup subtree can drive both sides by repeatedly offlining cgroups while concurrently creating/removing dentries, inodes, zswap entries, or triggering shrinker activity. The race is retryable and under attacker influence, so complexity is low.\nPR:L - Creating/removing the affected cgroups requires write access to a cgroup subtree, but Linux explicitly supports delegation of cgroup subtrees to less-privileged users and cgroup namespaces. No init-namespace root-only capability is inherent once such a subtree is delegated.\nUI:N - No victim user action is needed after the attacker has local access to the relevant cgroup subtree. The attacker can trigger cgroup teardown and concurrent LRU activity directly.\nS:U - The corruption occurs within the kernel memory-management and cgroup/list_lru scope and impacts the same kernel security authority. There is no VM escape, IOMMU bypass, or separate security scope crossing.\nC:H - The bug corrupts kernel list_head next/prev pointers in memcg-aware LRUs such as dentries, inodes, zswap, and workingset shadow nodes. Such kernel memory corruption can plausibly be shaped into disclosure primitives, and uncertainty is scored at the higher severity.\nI:H - Concurrent list operations under different locks can corrupt adjacent kernel object links and later list manipulation can write through attacker-influenced pointers. This is a kernel memory corruption primitive with plausible control-flow or arbitrary-write exploitation potential.\nA:H - Even without full exploitation, corrupted kernel list links can trigger list debugging splats, oopses, panics, hangs, or reclaim/list traversal failures. Kernel crash availability impact is high."
