- 7.8 High severity
Snapdragon: Out-of-bounds Write
Memory corruption may occur when invoking IOCTL calls from userspace to the camera kernel driver to dump request information, due to a missing memory requirement check.
- 7.8 High severity
Snapdragon: Improper Restriction of Operations within the Bounds of a Memory Buffer
Memory corruption occurs during an Escape call if an invalid Kernel Mode CPU event and sync object handle are passed with the DriverKnownEscape flag reset.
- 7.8 High severity
Snapdragon: Use After Free
Memory corruption during voice activation, when sound model parameters are loaded from HLOS, and the received sound model list is empty in HLOS drive.
- 7.8 High severity
Snapdragon: Use After Free
Memory corruption can occur when process-specific maps are added to the global list. If a map is removed from the global list while another thread is using it for a process-specific task, issues may arise.
- 7.0 High severity
Snapdragon: Use After Free
Memory corruption while invoking redundant release command to release one buffer from user space as race condition can occur in kernel space between buffer release and buffer access.
- 7.8 High severity
Qualcomm Multiple Chipsets Use-After-Free Exploited
Memory corruption while maintaining memory maps of HLOS memory.
- 7.5 High severity
Snapdragon: Buffer Over-read
Transient DOS when processing the non-transmitted BSSID profile sub-elements present within the MBSSID Information Element (IE) of a beacon frame that is received from over-the-air (OTA).
- 7.8 High severity
Snapdragon: Use After Free
Memory corruption can occur if VBOs hold outdated or invalid GPU SMMU mappings, especially when the binding and reclaiming of memory buffers are performed at the same time.
- 7.5 High severity
Snapdragon: Improper Authentication
Cryptographic issue while performing attach with a LTE network, a rogue base station can skip the authentication phase and immediately send the Security Mode Command.
- 7.8 High severity
Snapdragon: Out-of-bounds Write
Memory corruption while processing the event ring, the context read pointer is untrusted to HLOS and when it is passed with arbitrary values, may point to address in the middle of ring element.
- 7.8 High severity
Snapdragon: Use After Free
Memory corruption while processing Listen Sound Model client payload buffer when there is a request for Listen Sound session get parameter from ST HAL.
- 7.8 High severity
Qualcomm Multiple Chipsets Integer Overflow Exploited
Memory corruption in Graphics Linux while assigning shared virtual memory region during IOCTL call.
- 7.8 High severity
Qualcomm Multiple Chipsets Use of Out-of-Range Pointer Offset Exploited
Memory corruption while submitting a large list of sync points in an AUX command to the IOCTL_KGSL_GPU_AUX_COMMAND.
- 7.8 High severity
Qualcomm Multiple Chipsets Use-After-Free Exploited
Memory corruption in DSP Services during a remote call from HLOS to DSP.
- 7.8 High severity
Snapdragon: Use After Free
In the function call related to CAM_REQ_MGR_RELEASE_BUF there is no check if the buffer is being used. So when a function called cam_mem_get_cpu_buf to get the kernel va to use, another thread can call CAM_REQ_MGR_RELEASE_BUF to unmap the kernel va which cause
- 7.0 High severity
Snapdragon: Time-of-check Time-of-use (TOCTOU) Race Condition
The buffer obtained from kernel APIs such as cam_mem_get_cpu_buf() may be readable/writable in userspace after kernel accesses it. In other words, user mode may race and modify the packet header (e.g. header.count), causing checks (e.g. size checks) in kernel
- 7.8 High severity
Snapdragon: Access of Resource Using Incompatible Type
The cam_get_device_priv function does not check the type of handle being returned (device/session/link). This would lead to invalid type usage if a wrong handle is passed to it.
