What to do
AI-suggested
A fix for this issue has been implemented in the Linux kernel by adding calls to 'cond_resched' and 'touch_softlockup_watchdog' during task traversal in the OOM process. Users should apply the official kernel updates that include this fix to prevent the soft lockup condition. Since this is a kernel-level fix, upgrading to a patched kernel version is the recommended remediation.
Description
A soft lockup vulnerability was identified in the Linux kernel's memory control group (memcg) subsystem during the out-of-memory (OOM) process. The issue occurs when the OOM cgroup contains a large number of tasks (around 56,000), causing the kernel to take an excessive amount of time traversing these tasks, which triggers a soft lockup. The problem was addressed by introducing periodic rescheduling calls during task traversal to prevent the CPU from being stuck.
