In the Linux kernel, the following vulnerability has been resolved: i3c: renesas: Check that the transfer is valid before accessing it The Renesas I3C driver uses an asynchronous model to transfer data. It prepares a struct renesas_i3c_xfer, enqueues it, and waits for completion. The interrupt handler dequeues the transfer, updates/uses it, and signals the waiting thread. If the completion times out, the waiting thread dequeues the transfer and free it. If an interrupt fires after that, the handler may access freed memory, leading to crashes. Check that the transfer is still valid before accessing it in the interrupt handler. With it clear any status flags and disable all the interrupts to avoid triggering the same interrupts again.
