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
An issue was discovered in the m2m scaler driver in Samsung Mobile Processor and Wearable Processor Exynos 9820, 9825, 980, 990, 850,and W920. A Use-After-Free in the mobile processor leads to privilege escalation.

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 m2m (memory-to-memory) scaler driver of Samsung Exynos mobile processors (9820, 9825, 980, 990, 850, W920). The UAF condition in the scaler driver can be exploited to achieve privilege escalation, potentially allowing an attacker to gain elevated kernel-level access on affected devices.

MitigationApply vendor-provided security patches from Samsung; this is a firmware-level vulnerability requiring updated processor/firmware images. Users should ensure their devices are running the latest Samsung security updates.

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 the Exynos processor model
    Check /proc/cpuinfo or dmesg for 'Exynos' processor identifier; on Android devices, use 'getprop' or check /sys/devices/soc0/soc_id
    Affected if The device contains an Exynos 9820, 9825, 980, 990, 850, or W920 processor - any of these models means the device is within the affected product range
  2. Verify the scaler driver is loaded
    Check for the presence of the m2m scaler driver module in /proc/modules, /sys/module/, or via 'lsmod' command; look for 'scaler' or 'm2m' related kernel modules
    Affected if The scaler driver module is present and loaded in the kernel, indicating the vulnerable component is active on the device
  3. Confirm firmware version
    Query the bootloader or baseband firmware version through 'getprop ro.build.version.security_patch', 'AT command' interface, or check /vendor/firmware directory for scaler-related firmware files
    Affected if The device firmware cannot be determined or predates the July 2024 Samsung security patch level - all historical versions of the listed Exynos models are affected
  4. Check kernel configuration for scaler support
    Inspect /boot/config-* or /proc/config.gz for CONFIG_EXYNOS_SCALER or similar scaler-related kernel configuration options
    Affected if Scaler driver support is compiled into the kernel (CONFIG_EXYNOS_SCALER=y or =m), meaning the attack surface is present

If the device uses any of the Exynos 9820, 9825, 980, 990, 850, or W920 processors and runs firmware prior to the July 2024 Samsung security update, the environment is affected by this Use-After-Free vulnerability in the m2m scaler driver.
