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

Description The issue is related to alignment handling in the Linux kernel's riscv/purgatory component. When alignment handling is delegated to the kernel, everything must be word-aligned in purgatory. Without proper alignment, hitting an exception would ultimately crash. The kernel's handler would take care of exceptions on other occasions. This has been tested on a JH7110 SoC with oreboot and its SBI delegating unaligned access exceptions, and the kernel configured to handle them.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
