Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
In PVRSRV_MMap of pvr_bridge_k.c, there is a possible arbitrary code execution due to a logic error in the code. This could lead to local escalation of privilege in the kernel with no additional execution privileges needed. User interaction is not needed for exploitation.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · moderate confidence

A logic error in the PVRSRV_MMap function within the PowerVR graphics driver kernel module (pvr_bridge_k.c) allows a local attacker to escalate privileges to kernel level and achieve arbitrary code execution, due to improper validation or control flow in the memory mapping handler.

MitigationApply the vendor-provided security patch for this vulnerability. If unavailable, restrict or disable the PowerVR graphics driver until a patch can be deployed.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Confirm PowerVR graphics driver presence
    Identify if the device uses PowerVR GPU hardware and has the PowerVR graphics driver loaded. This can be done by checking kernel modules or system information that indicates PowerVR GPU usage.
    Affected if The device has PowerVR graphics hardware and the corresponding driver (pvr_bridge or similar PowerVR kernel module) is present and enabled.
  2. Check for vulnerable driver module
    Locate and inspect the PowerVR kernel module file (pvr_bridge_k.c compiled module) in the system's kernel or module directories.
    Affected if The pvr_bridge kernel module exists on the system and exposes the PVRSRV_MMap function.
  3. Verify mmap handler availability
    Determine if the PVRSRV_MMap function is exposed and callable through the pvr_bridge interface, which handles memory mapping requests from user space.
    Affected if The mmap handler in the PowerVR driver is accessible and processing user-space memory mapping requests.
  4. Confirm user-space driver components
    Check for the presence of user-space PowerVR driver components (such as pvr_bridge.ko or related files) that would interact with the kernel module.
    Affected if Both kernel-space (pvr_bridge) and user-space PowerVR driver components are installed and active.

The device is affected if it runs Android with PowerVR graphics hardware and has the PowerVR driver (pvr_bridge kernel module) loaded and enabled, as the logic error in the PVRSRV_MMap function can then be exploited for privilege escalation.

Mitigation

Apply the vendor-provided security patch for this vulnerability. If unavailable, restrict or disable the PowerVR graphics driver until a patch can be deployed.

Recommended fix Moderate confidence

Android Security Patch Level May 2024 or later (contact your device manufacturer for specific firmware)

  1. 1. Check the Android Security Bulletin for the month this CVE was addressed (CVE-2024-34726 was addressed in the May 2024 Android Security Bulletin)
  2. 2. Apply the latest Android security patch level for your device
  3. 3. Verify the patch was applied by checking Settings > About Phone > Android version - ensure the Security patch level is May 2024 or later
  4. 4. If your device manufacturer has not released this patch, consider upgrading to a device model that receives regular security updates
Caveat Some older devices may no longer receive security updates; consider upgrading to a device with active support
