Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)
Description The issue is related to the Linux kernel's mhi component, where an unaligned read pointer in the event ring could lead to multiple issues like Denial of Service (DoS) or ring buffer memory corruption. The kernel expects event ring elements to be 128 bits (struct mhi ring element) aligned. An unaligned read pointer poses a risk, and to mitigate this, an alignment check for the event ring read pointer has been added.
Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
