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 ufshc_scsi_cmd of ufs.c, there is a possible stack variable use after free due to a use after free. This could lead to local escalation of privilege 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 use-after-free vulnerability exists in the UFS (Universal Flash Storage) host controller driver (ufshc_scsi_cmd function in ufs.c) where a stack variable is accessed after being freed, leading to local privilege escalation without requiring user interaction or additional privileges.

MitigationApply the upstream kernel patch for CVE-2024-47017 which fixes the use-after-free in the UFS host controller driver; this is a Linux kernel vulnerability requiring a kernel update or backported fix.

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 device runs Android
    Run 'getprop ro.build.version.release' or check system information to verify the operating system is Android
    Affected if Device is not running Android (this CVE only affects Android)
  2. Check kernel version
    Run 'uname -r' or check /proc/version to obtain the kernel version
    Affected if Kernel version has not received the CVE-2024-47017 fix (compare against upstream patch date)
  3. Verify UFS driver is present
    Check if the UFS host controller driver module exists: 'ls /sys/module/ufs*' or 'grep -i ufs /proc/modules'; if built-in, check kernel config for CONFIG_SCSI_UFSHCD
    Affected if UFS driver (ufs.ko or CONFIG_SCSI_UFSHCD) is not loaded or not compiled in the kernel
  4. Confirm UFS storage is in use
    Check /proc/scsi/scsi or lsblk to verify the device uses UFS storage, or check 'cat /sys/block/*/device/type' for UFS devices
    Affected if Device does not use UFS storage (the vulnerable code path is only triggered when UFS storage is present)

A device is affected if it runs Android with an unpatched kernel version AND has the UFS host controller driver loaded/compiled AND uses UFS storage, allowing the use-after-free in ufshc_scsi_cmd to be triggered for local privilege escalation.
