- Details
-
In the Linux kernel, the following vulnerability has been resolved:
firmware: qcom: scm: Cleanup global '__scm' on probe failures
If SCM driver fails the probe, it should not leave global '__scm' variable assigned, because external users of this driver will assume the probe finished successfully. For example TZMEM parts ('__scm->mempool') are initialized later in the probe, but users of it (__scmsmccall()) rely on the '__scm' variable.
This fixes theoretical NULL pointer exception, triggered via introducing probe deferral in SCM driver with call trace:
