Description OSIDB Bzimport 2026-10-18 16:04:26 UTC 
In the Linux kernel, the following vulnerability has been resolved:

rtc: spear: initialize IRQ state before requesting alarm IRQ

devm_request_irq() enables the interrupt before it returns, so the handler
may run while probe is still initializing the device. Initialize the MMIO
address and spinlock before requesting the alarm IRQ.
