Severity

7.3 (High) - CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L

Summary

In Qualcomm Android for MSM, Firefox OS for MSM, and QRD Android with all Android releases from CAF using the Linux kernel before security patch level 2018-04-05, in the function wma_tbttoffset_update_event_handler(), a parameter received from firmware is used to allocate memory for a local buffer and is not properly validated. This can potentially result in an integer overflow subsequently leading to a heap overwrite.
