CVE-2024-45828
In the Linux kernel, the following vulnerability has been resolved: i3c: mipi-i3c-hci: Mask ring interrupts before ring stop request Bus cleanup path in DMA mode may trigger a RING_OP_STAT interrupt when the ring is being stopped.
Does this matter?
Lower severity and a low EPSS score (0.25%). Track it; it rarely justifies an emergency change on its own.
Description
In the Linux kernel, the following vulnerability has been resolved: i3c: mipi-i3c-hci: Mask ring interrupts before ring stop request Bus cleanup path in DMA mode may trigger a RING_OP_STAT interrupt when the ring is being stopped. Depending on timing between ring stop request completion, interrupt handler removal and code execution this may lead to a NULL pointer dereference in hci_dma_irq_handler() if it gets to run after the io_data pointer is set to NULL in hci_dma_cleanup(). Prevent this my masking the ring interrupts before ring stop request.
