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

Description The issue is related to a race condition that occurs when detecting vmap stack overflow in the Linux kernel for riscv. Specifically, when two or more harts use the same shadow stack at the same time, a race condition arises. To address this, an atomic variable spin shadow stack is introduced, which is swapped between its own address and 0 in an atomic way. This variable indicates whether the shadow stack is being used or not.

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