Technical details
A memory corruption vulnerability exists in Qualcomm firmware/drivers due to improper handling of IOCTL (Input/Output Control) calls during escape operations. The vulnerability is classified as an out-of-bounds read (CWE-125), though the reported impact includes high confidentiality, integrity, and availability loss, suggesting it may lead to broader memory corruption or privilege escalation. An attacker with local access and low privileges can exploit this flaw to read sensitive memory or crash the system. The issue was disclosed in the June 2026 Qualcomm Security Bulletin.
