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 · high confidence

A user-space process can corrupt kernel virtual memory pages by passing a crafted (maliciously constructed) memory page to a kernel API. This constitutes a local privilege escalation vulnerability allowing an unprivileged process to potentially gain kernel-level code execution or corrupt kernel memory.

MitigationApply vendor-supplied firmware/security updates from Qualcomm for affected Snapdragon chipset devices. Until patches are available, limit device access to trusted users and monitor for indicators of local privilege escalation attempts.

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. Identify chipset model
    Check the device's SoC or chipset information via /proc/cpuinfo, boot logs, or vendor documentation
    Affected if The chipset matches one of the affected models: Bitra, Ipq6018, Ipq8074, Mdm9205, Nicobar, Qca8081, Qcn7605, or Qcs404
  2. Locate firmware version
    Retrieve the firmware version from the device's system information, bootloader, or /proc/version
    Affected if The firmware version is present and corresponds to a Qualcomm chipset in the affected list
  3. Determine kernel API exposure
    Identify if the kernel interface for memory page handling is accessible to user-space processes - check for specific ioctl calls or memory mapping interfaces exposed by kernel modules
    Affected if Unprivileged user-space processes can access the kernel API that handles memory page passing
  4. Check for privilege boundaries
    Verify whether the device permits unprivileged shell access or allows running custom executables from non-privileged accounts
    Affected if Untrusted or unprivileged users have shell or execution access to the device
  5. Review system logs for indicators
    Examine kernel logs (dmesg, /var/log/kern.log) and system audit logs for signs of memory corruption, kernel panics, or privilege escalation attempts
    Affected if Logs show unexpected kernel memory corruption or privilege escalation activity related to memory page handling

If the device uses an affected Qualcomm chipset (Bitra, Ipq6018, Ipq8074, Mdm9205, Nicobar, Qca8081, Qcn7605, or Qcs404) and exposes kernel memory APIs to unprivileged users, the environment is likely vulnerable to local privilege escalation via this CVE.
