CVE-2017-8247
In all Qualcomm products with Android releases from CAF using the Linux kernel, if there is more than one thread doing the device open operation, the device may be opened more than once.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.40%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
