Vulnerability Title
tracing: Do not let histogram values have some modifiers
来源: CVE Program / CVE List V5
Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved:
tracing: Do not let histogram values have some modifiers
Histogram values can not be strings, stacktraces, graphs, symbols,
syscalls, or grouped in buckets or log. Give an error if a value is set to
do so.
Note, the histogram code was not prepared to handle these modifiers for
histograms and caused a bug.
Mark Rutland reported:
# echo 'p:copy_to_user __arch_copy_to_user n=$arg2' >> /sys/kernel/tracing/kprobe_events
# echo 'hist:keys=n:vals=hitcount.buckets=8:sort=hitcount' > /sys/kernel/tracing/events/kprobes/copy_to_user/trigger
# cat /sys/kernel/tracing/events/kprobes/copy_to_user/hist
