| Vector | AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:H |
Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
The issue is related to a stack-out-of-bound access in SPMI tracing functions. Specifically, the functions
trace spmi write begin() and trace spmi read end() call memcpy() with a length of "len + 1", leading to one extra byte being read beyond the end of the specified buffer. This out-of-bound memory access can be fixed by using a length of "len" instead. A KASAN log shows the issue, indicating a read of size 2 at a specific address by a task, resulting in a stack-out-of-bounds error.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
