CVE-2018-9456Network attack vector

Remote device crash via Bluetooth SDP bounds error

Published Nov 19, 2024 · Updated Nov 21, 2024

Out-of-bounds read in Android 7.0 through 8.1 allows remote attackers to crash a device through a crafted Bluetooth SDP message. The sdpu_extract_attr_seq parser in sdp_utils.cc applies an incorrect bounds check while extracting an SDP attribute sequence, permitting reads beyond the supplied buffer. Exploitation requires no privileges or user interaction and is limited to service interruption, with no reported data-reading or code-execution capability.
