Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to the fixed version

Description The issue is related to the Linux kernel's stack unwinding function, walk stackframe, which can lead to a stack-out-of-bounds error when CONFIG FRAME POINTER is unset and KASAN is enabled. This can cause the kernel to crash. The error occurs when the walk stackframe function randomly reads the stack, resulting in a backtrace. The issue is resolved by using READ ONCE NOCHECK when reading the stack in imprecise mode.

Recommendations To resolve the issue, update the Linux kernel to a version that includes the fix. As a temporary workaround, consider disabling the walk stackframe function or restricting its use until a patch is available. However, since the provided information does not specify the exact fixed version, it is recommended to update to the latest available version of the Linux kernel.
