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 apply_minlock_constraint of dvfs.c, there is a possible out of bounds read due to a missing bounds check. This could lead to local information disclosure 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 · high confidence

An out-of-bounds read vulnerability exists in the apply_minlock_constraint function in dvfs.c within the Linux kernel. The vulnerability is caused by a missing bounds check, allowing a local attacker to potentially read sensitive information from kernel memory without elevated privileges or user interaction.

MitigationApply the vendor-provided Linux kernel security patch that implements proper bounds checking in the apply_minlock_constraint function in dvfs.c.

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. Check the Android kernel version
    Run 'uname -r' or check Settings > About Phone > Kernel Version to obtain the running kernel version
    Affected if The kernel version is unpatched and falls within the range containing the vulnerable apply_minlock_constraint function in dvfs.c
  2. Identify if the dvfs driver is present
    Check for dvfs-related kernel modules or drivers by running 'ls -la /sys/module/ | grep dvfs' or searching for dvfs.c in /proc/kallsyms
    Affected if The dvfs driver/module is loaded and the kernel lacks the bounds check patch for apply_minlock_constraint
  3. Verify the apply_minlock_constraint function exists
    Search for the function symbol in the kernel by running 'grep -i apply_minlock_constraint /proc/kallsyms' or examining the kernel symbol table
    Affected if The function is present in the running kernel without the security fix applied
  4. Check for vendor security patch level
    Go to Settings > About Phone > Security Patch Level or run 'getprop ro.build.version.security_patch' to see the installed Android security patch date
    Affected if The security patch level is older than the vendor release that addresses CVE-2024-29742

A user is affected if their Android device runs a kernel with the vulnerable dvfs.c apply_minlock_constraint function and lacks the corresponding security patch.
