## Technical details

A memory corruption vulnerability exists in the Qualcomm fastboot implementation due to improper validation of syntactic correctness of input (CWE-1286). The flaw is triggered when the bootloader processes improperly formatted fastboot commands. An attacker with physical access and administrative/high privileges can exploit this to achieve a scope change, potentially gaining unauthorized access to secure memory regions or executing arbitrary code at the bootloader level. The vulnerability is tracked as CVE-2026-24091 and was addressed in the June 2026 Qualcomm security bulletin.
