A second Qualcomm GPU micronode memory corruption vulnerability (CVE-2025-21479, CVSS 8.6) exists in the unauthorized command execution path during specific GPU command sequences. KEV-listed alongside CVE-2025-21480, this indicates a systemic issue in Qualcomm's GPU micronode command validation that is being actively exploited in mobile attack chains.

Qualcomm GPU micronode contains a memory corruption vulnerability (CVE-2025-21480, CVSS 8.6) caused by unauthorized command execution during specific GPU command sequences. KEV-listed, this vulnerability enables privilege escalation from the GPU context, potentially allowing app-level attackers to gain kernel access through the GPU driver on Qualcomm-based Android devices.

CVE-2024-53026 is an information disclosure vulnerability in IMS (IP Multimedia Subsystem) implementations affecting VoLTE and VoWiFi call processing. When a malicious or malformed RTCP (Real-time Transport Control Protocol) packet is received during an active call, the vulnerable system leaks sensitive information to a network-adjacent attacker without requiring authentication or user interaction. The CVSS 8.2 rating reflects high confidentiality impact with partial availability degradation; exploitation likelihood and real-world activity status require cross-referencing with EPSS and KEV data.

CVE-2024-53021 is an information disclosure vulnerability in RTCP (Real-time Transport Control Protocol) packet processing that allows unauthenticated remote attackers to leak sensitive data through malicious goodbye (BYE) RTCP packets. The vulnerability affects multiple VoIP and real-time communication products processing RTCP traffic; attackers can extract confidential information across the network without authentication or user interaction, and may also cause limited availability impact. The high CVSS score of 8.2 reflects the severe confidentiality impact and network-based attack vector, though exploitation complexity is low.

CVE-2024-53020 is an information disclosure vulnerability in RTP (Real-time Transport Protocol) packet processing that occurs when decoding packets with malformed header extensions. An attacker on the network can send specially crafted RTP packets to trigger memory disclosure, potentially exposing sensitive information while also causing minor availability impact. The vulnerability affects multiple implementations of RTP protocol handling across various media processing frameworks and VoIP applications; while there is no confirmed active KEV status or public exploit code documented, the high CVSS score (8.2) combined with network accessibility (CVSS:3.1/AV:N) indicates significant real-world risk to exposed services.

Memory corruption while processing IOCTL command to handle buffers associated with a session.

Memory corruption vulnerability in Qualcomm's Virtual Machine (VM) attachment mechanism that occurs when the Host Linux OS (HLOS) retains access to a VM during attachment operations. This local privilege escalation vulnerability affects Qualcomm System-on-Chip (SoC) implementations and allows a local attacker with user-level privileges to achieve code execution with full system compromise (confidentiality, integrity, and availability impact). The vulnerability has not been reported as actively exploited in the KEV catalog, but the high CVSS score (7.8) and local attack vector indicate significant real-world risk for deployed Qualcomm-based devices.

Transient DOS while connecting STA to AP and initiating ADD TS request from AP to establish TSpec session. Rated high severity (CVSS 7.5), this vulnerability is remotely exploitable, no authentication required, low attack complexity. No vendor patch available.

Memory corruption occurs while connecting a STA to an AP and initiating an ADD TS request. Rated high severity (CVSS 7.5), this vulnerability is remotely exploitable, no authentication required, low attack complexity. No vendor patch available.

Cryptographic issue occurs during PIN/password verification using Gatekeeper, where RPMB writes can be dropped on verification failure, potentially leading to a user throttling bypass. Rated medium severity (CVSS 6.2), this vulnerability is no authentication required, low attack complexity. No vendor patch available.

There may be information disclosure during memory re-allocation in TZ Secure OS. Rated medium severity (CVSS 5.5), this vulnerability is low attack complexity. No vendor patch available.

Memory corruption while assigning memory from the source DDR memory(HLOS) to ADSP. Rated high severity (CVSS 7.5). No vendor patch available.
