Summary

This vulnerability allows attackers with local user privileges to cause memory corruption when system service routines execute, potentially leading to arbitrary code execution. The flaw occurs due to improper handling of user input buffers during system service execution.

Exploitability

Exploitation requires local user access and is moderately difficult, needing precise control over input buffers to trigger the memory corruption during service routine execution.

Blast radius

If exploited, this vulnerability could allow attackers to execute arbitrary code with system privileges on affected Qualcomm-based devices, potentially affecting multiple network services and device functionality.

Detection

No reliable host or network indicator is derivable from the published description.

Prioritized remediation

Upgrade to firmware version 2.590 or later for all affected devices including FastConnect 6700, 6900, and 7800 models.
