Overview<\/strong><\/p>\n

The cybersecurity world is yet again faced with another critical vulnerability, CVE-2025-22435, which, if exploited, could lead to severe system compromise or data leakage. This vulnerability resides in ‘avdt_msg_ind’ of ‘avdt_msg.cc’, causing a possible memory corruption due to type confusion. This vulnerability is especially dangerous as it does not require any additional execution privileges<\/a> or user interaction for exploitation, making any paired device potentially susceptible to an escalated privilege attack.
\nThis article will delve into the details of CVE-2025-22435, discussing the severity and potential impact of this vulnerability<\/a>, the affected products, and how the exploit works. We will also provide guidance for mitigation to help you secure your systems against this flaw<\/a>.<\/p>\n

Vulnerability Summary<\/strong><\/p>\n

CVE ID: CVE-2025-22435
\nSeverity: Critical, with a CVSS score of 9.8
\nAttack Vector: Local
\nPrivileges Required: None
\nUser Interaction: None
\nImpact: Potential system<\/a> compromise or data leakage<\/p>\n

Affected Products<\/strong><\/p>\n

Product | Affected Versions<\/p>\n

Bluetooth Stack<\/a> | All versions
\n(Inference based on the vulnerability<\/a> description, actual products and versions may vary)<\/p>\n

How the Exploit Works<\/strong><\/p>\n

The CVE-2025-22435 vulnerability is a memory corruption flaw caused by type<\/a> confusion in the ‘avdt_msg_ind’ of ‘avdt_msg.cc. This vulnerability could be exploited by an attacker sending a specifically crafted message to the targeted system. This message would lead to type confusion, leading to memory<\/a> corruption.
\nAn attacker exploiting this vulnerability could escalate their privileges<\/a> on the paired device without any additional execution privileges needed, making this a highly severe vulnerability. Since it does not require user interaction, the exploit could be launched silently, making detection and prevention more challenging.<\/p>\n
