CVE-2023-52660
In the Linux kernel, the following vulnerability has been resolved: media: rkisp1: Fix IRQ handling due to shared interrupts The driver requests the interrupts as IRQF_SHARED, so the interrupt handlers can be called at any time.
Does this matter?
Lower severity and a low EPSS score (0.22%). Track it; it rarely justifies an emergency change on its own.
Description
In the Linux kernel, the following vulnerability has been resolved: media: rkisp1: Fix IRQ handling due to shared interrupts The driver requests the interrupts as IRQF_SHARED, so the interrupt handlers can be called at any time. If such a call happens while the ISP is powered down, the SoC will hang as the driver tries to access the ISP registers. This can be reproduced even without the platform sharing the IRQ line: Enable CONFIG_DEBUG_SHIRQ and unload the driver, and the board will hang. Fix this by adding a new field, 'irqs_enabled', which is used to bail out from the interrupt handler when the ISP is not operational.
