CVE-2026-89769

A flaw was found in the Linux kernel's NXP PIT Programmable Interrupt Timer clocksource driver. When the CPU hotplug setup fails after an interrupt request IRQ has been successfully registered, the error handling does not properly free the IRQ. This oversight results in a leaked IRQ line and a...

CVE-2026-89769

CVE-2026-89769 affects the NXP PIT clocksource driver in the Linux kernel. When cpuhp_setup_state fails after pit_clockevent_per_cpu_init has successfully registered an IRQ via request_irq , the error path skips releasing that IRQ and jumps directly to unregistering the clocksource. Since kfree(p...
