CVE-2019-14063Network attack vector

Kernel failure via invalid DAPM mux input

Published Feb 7, 2020 · Updated Aug 5, 2024

Out-of-bounds access in Qualcomm Snapdragon firmware allows remote attackers to cause kernel failure via invalid DAPM mux settings. The DAPM mux settings path processes an invalid selector and performs an out-of-bounds access that terminates the kernel. The published assessment models unauthenticated network reachability and reports availability and confidentiality impact, with no integrity impact described.
