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

Description An issue exists in the Linux kernel related to stack unwinding and Kernel Address Sanitizer (KASAN) checks. When unwinding the stack of a task other than the current task, KASAN may incorrectly report an out-of-bounds error in the walk stackframe function. This issue is similar to one previously addressed on x86 architecture through commit 84936118bdf3 ("x86/unwind: Disable KASAN checks for non-current tasks"), and the same solution can be applied to RISC-V.

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