CVE-2026-98818

The Linux kernel contains a deadlock vulnerability in the mm/slab component. The issue arises because kfree_rcu() can be called while holding the pi_lock (a raw spinlock in the scheduler). If kfree_rcu() attempts to allocate memory using __GFP_KSWAPD_RECLAIM , it can wake up kswapd , which then t...
