CVE-2023-52766

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description The issue is related to an out of bounds access in the hci dma irq handler() function. This occurs when looping over ring headers that are not allocated and enabled in hci dma init(), resulting in out of bounds access from rings->headers[i] access when i is greater than or equal to the number of allocated ring headers. The function hci dma irq handler() is vulnerable due to this improper handling.
