| Vector | AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H |
Name of the Vulnerable Software and Affected Versions:
Linux kernel versions prior to 6.6.61
Description:
The issue is related to the LoongArch architecture in the Linux kernel, where tasks without a vDSO mapped can cause a crash when calling the
stack top() function. This can occur when using kunit, leading to a dereference of the NULL vdso pointer and a subsequent crash. The crash can happen due to the lack of a vDSO mapping for certain tasks, such as kthreads.Recommendations:
For Linux kernel versions prior to 6.6.61, update to version 6.6.61 or later to resolve the issue. As a temporary workaround, consider avoiding the use of kunit or restricting its functionality to minimize the risk of exploitation.
