In the Linux kernel, the following vulnerability has been resolved:

spmi: trace: fix stack-out-of-bound access in SPMI tracing functions

trace_spmi_write_begin() and trace_spmi_read_end() both call memcpy() with a length of "len + 1". This leads to one extra byte being read beyond the end of the specified buffer. Fix this out-of-bound memory access by using a length of "len" instead.

Here is a KASAN log showing the issue:
