- Summary
- CVE-2024-45828 affecting package kernel for versions less than 5.15.176.3-1
- Details
-
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.
