CVE-2026-89769

CVE-2026-89769 affects the NXP PIT (Programmable Interrupt Timer) clocksource driver in the Linux kernel. The root cause is an IRQ leak on the cpuhp_setup_state error path: when this call fails after request_irq has succeeded, the cleanup path skips releasing the IRQ. Because kfree(pit) follows, ...
