**Name of the Vulnerable Software and Affected Versions** Linux kernel (affected versions not specified) **Description** An issue exists in the x86 shadow stacks implementation where the `shstk pop sigframe()` function fails to check for errors returned by `mmap read lock killable()`. This occurs because the function was not marked with ` must check`, which is a compiler attribute used to ensure that the return value of a function is not ignored. **Recommendations** At the moment, there is no information about a newer version that contains a fix for this vulnerability.
