Descriptions

In the Linux kernel, the following vulnerability has been resolved: i3c: mipi-i3c-hci: Fix out of bounds access in hci_dma_irq_handler Do not loop over ring headers in hci_dma_irq_handler() that are not
allocated and enabled in hci_dma_init(). Otherwise out of bounds access
will occur from rings->headers[i] access when i >= number of allocated
ring headers.

En el kernel de Linux, se resolvió la siguiente vulnerabilidad: i3c: mipi-i3c-hci: corrige el acceso fuera de los límites en hci_dma_irq_handler. No realice bucles sobre encabezados de anillo en hci_dma_irq_handler() que no estén asignados y habilitados en hci_dma_init(). De lo contrario, el acceso fuera de los límites se producirá desde el acceso de anillos->encabezados[i] cuando i >= número de encabezados de anillo asignados.
