In the Linux kernel, the following vulnerability has been resolved: media:
rkisp1: Fix IRQ disable race issue In rkisp1_isp_stop() and
rkisp1_csi_disable() the driver masks the interrupts and then apparently
assumes that the interrupt handler won’t be running, and proceeds in the
stop procedure. This is not the case, as the interrupt handler can already
be running, which would lead to the ISP being disabled while the interrupt
handler handling a captured frame. This brings up two issues: 1) the ISP
could be powered off while the interrupt handler is still running and
accessing registers, leading to board lockup, and 2) the interrupt handler
code and the code that disables the streaming might do things that
conflict. It is not clear to me if 2) causes a real issue, but 1) can be
seen with a suitable delay (or printk in my case) in the interrupt handler,
leading to board lockup.
