CVE-2017-15817
In all Qualcomm products with Android releases from CAF using the Linux kernel, when an access point sends a challenge text greater than 128 bytes, the host driver is unable to validate this potentially leading to authentication failure.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.86%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
