CVE-2018-11847
Malicious TA can tag QSEE kernel memory and map to EL0, there by corrupting the physical memory as well it can be used to corrupt the QSEE kernel and compromise the whole TEE in Snapdragon Auto, Snapdragon Compute, Snapdragon Connectivity, Snapdragon…
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.23%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
