[lttng-dev] [RELEASE] LTTng-modules 2.9.6 and 2.10.3 (Linux kernel tracer)

[Mathieu Desnoyers]

Hi,

Versions 2.9.6 and 2.10.3 fix an input validation issue with
the /proc/lttng-logger interface of lttng-modules. An ill-crafted input
to the write system call to /proc/lttng-logger can trigger a kernel OOPS.

Given that all users can write to that file, it means that arbitrary
local users can trigger a kernel OOPS. It would be preferable to
upgrade your lttng-modules to a version containing this fix.

Thanks,

Mathieu
