What is CVE-2026-58882?
CVE-2026-58882 refers to an out-of-bounds read vulnerability found in the WapPushOverSms component of the Android operating system, developed by Google. This issue is tied to a flaw within the decodeWapPdu function in the WapPushOverSms.java file, which allows for an integer overflow condition. As a result, attackers can exploit this vulnerability to perform read operations beyond the allocated memory boundaries. This exploitation does not require user interaction, making it particularly dangerous, as it can potentially disrupt the normal operation of the device or application without requiring any engagement from the user. Consequently, organizations leveraging Android devices or applications that utilize the WapPushOverSms component may face significant operational disruptions and security concerns.
Potential impact of CVE-2026-58882
-
Remote Denial of Service: The primary impact of this vulnerability is the potential for a remote denial of service. Attackers can exploit the out-of-bounds read to cause system crashes or application failures, leading to downtime and loss of service availability.
-
Exploitation without User Interaction: The vulnerability's ability to be exploited without any required user action heightens the risk, as malicious actors can potentially target systems en masse without relying on phishing or similar tactics. This increases the likelihood of widespread attacks.
-
Increased Attack Surface: Given that this vulnerability resides within a widely used component of the Android system, it may broaden the attack surface for threat actors. Devices running affected versions of Android could become targets for rapid exploitation, especially if patches are not applied promptly, prompting cascading security risks across networks and enterprises.
Affected Version(s)
