CVE-2025-37815

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> misc: microchip: pci1xxxx: Fix Kernel panic during IRQ handler registration<br /> <br /> Resolve kernel panic while accessing IRQ handler associated with the<br /> generated IRQ. This is done by acquiring the spinlock and storing the<br /> current interrupt state before handling the interrupt request using<br /> generic_handle_irq.<br /> <br /> A previous fix patch was submitted where &amp;#39;generic_handle_irq&amp;#39; was<br /> replaced with &amp;#39;handle_nested_irq&amp;#39;. However, this change also causes<br /> the kernel panic where after determining which GPIO triggered the<br /> interrupt and attempting to call handle_nested_irq with the mapped<br /> IRQ number, leads to a failure in locating the registered handler.
