    Ubuntu Linux kernels 6.8, 6.17, and 7.0 contain a bug in AppArmor notification handling code that can be triggered by any unprivileged local user to crash the kernel or cause it to hang. The issue stems from code that incorrectly sleeps while holding a spinlock—a low-level synchronization primitive—creating a condition where the system becomes unresponsive or fails entirely. An attacker with basic local access can reliably exploit this without special privileges or user interaction.
