AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N
Network-delivered RTCP packet needs no attacker privileges; UI:R because victim must join a media session; C:H reflects unbounded memory read potential; no integrity or availability impact.

In RtcpFbPacket::decodeRtcpFbPacket, there is a possible out of bounds read due to an integer overflow. This could lead to remote information disclosure with no additional execution privileges needed. User interaction is needed for exploitation.
AnalysisAI
Remote information disclosure in Android's RTCP Feedback packet decoder allows a network attacker to read out-of-bounds process memory on a target device by delivering a maliciously crafted RTCP FB packet. The root cause is a CWE-190 integer overflow in RtcpFbPacket::decodeRtcpFbPacket that causes a miscalculated buffer boundary, enabling the out-of-bounds read. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires the target Android user to actively participate in or connect to a media session that delivers RTCP Feedback packets from the attacker - for example, by joining an attacker-controlled VoIP call, video conference, or media stream (CVSS UI:R). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 base score of 6.5 (Medium) is well-calibrated for this class of vulnerability: AV:N/AC:L/PR:N establishes a low-friction network attack path, but UI:R imposes a meaningful exploitation barrier requiring the target to actively engage with a media session. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker operates a malicious VoIP or video conferencing service and social-engineers a target Android user into joining a call or media session. When the victim's Android device processes the attacker's specially crafted RTCP Feedback packet, the integer overflow in decodeRtcpFbPacket miscalculates the buffer boundary, causing the decoder to read memory beyond the packet buffer. … |
| Remediation | Apply the security patches delivered via the Google Pixel Security Bulletin dated 2026-06-01, available at https://source.android.com/docs/security/bulletin/pixel/2026/2026-06-01; devices should be updated to the June 2026 security patch level or later. … Detailed patch versions, workarounds, and compensating controls in full report. |
