CVE-2026-89752

A flaw was found in the Linux kernel's memory cgroup memcg component. When multiple file operations concurrently update memory.high or memory.max files in kernfs, a writer can continue reclaiming memory towards an outdated target. This can lead to an indefinite loop, causing a denial of service D...

CVE-2026-89752

A race condition in the Linux kernel's memory cgroup (memcg) subsystem can cause an indefinite reclaim loop when two open files concurrently update memory.max or memory.high. Because kernfs serializes operations only per open file, a first writer may continue reclaiming toward a stale target afte...

kernel: memcg: OOM handling DoS

It was found that the Linux kernel memory resource controller's memcg handling of OOM out of memory conditions could lead to deadlocks. An attacker able to continuously spawn new processes within a single memory-constrained cgroup during an OOM event could use this flaw to lock up the system...
