Technical details

A memory corruption vulnerability exists in Qualcomm diagnostic services due to an out-of-bounds write (CWE-787) caused by a lack of proper input validation. The vulnerability is exploitable locally by an attacker with high privileges (PR:H), requiring no user interaction. Successful exploitation allows the attacker to corrupt memory, which can lead to a loss of confidentiality, integrity, and availability of the affected system. The issue was disclosed in the June 2026 Qualcomm Security Bulletin.
