1) Integer overflow (CVE-ID: CVE-2018-5820)
The vulnerability allows a remote non-authenticated attacker to read and manipulate data.
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.
