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 pblS2mpuResume of s2mpu.c, there is a possible mitigation bypass due to a logic error in the code. 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 logic error in the pblS2mpuResume function within the S2MPU (Secure Memory Protection Unit) subsystem allows a local attacker to bypass existing mitigations and escalate privileges. The vulnerability resides in the resume path of the memory protection unit, likely during transition from a low-power or secure state, enabling privilege escalation without requiring additional execution privileges or user interaction.

MitigationApply the vendor-provided security patch for CVE-2024-29741, which should address the logic error in the S2MPU resume path. If no patch is available, consider disabling or restricting access to the affected subsystem and monitor for exploitation indicators.

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 is running Android
    Check the operating system by looking at /system/build.prop or running 'getprop ro.build.version.release'
    Affected if The device is NOT running Android (this CVE only affects Android devices)
  2. Determine if S2MPU hardware is present
    Check for S2MPU device nodes in /sys/kernel/debug or /dev/ - look for 's2mpu' entries, or check dmesg for 's2mpu' or 'S2MPU' kernel messages
    Affected if S2MPU hardware is present and accessible on the device; if not present, the specific attack surface does not exist
  3. Verify kernel version and patch level
    Run 'getprop ro.build.version.security_patch' to check the Android security patch level
    Affected if The security patch level is earlier than the vendor fix date for CVE-2024-29741 (patch date varies by vendor)
  4. Check for indicators of local privilege escalation
    Review audit logs (ausearch, dmesg) and process accounting logs for unexpected privilege escalation events, particularly involving processes gaining root or SYSTEM privileges unexpectedly
    Affected if Unexpected privilege escalation events are observed in logs without corresponding legitimate system operations

A user is affected if the device runs Android with S2MPU hardware present and the security patch for CVE-2024-29741 has not been applied.

Mitigation

Apply the vendor-provided security patch for CVE-2024-29741, which should address the logic error in the S2MPU resume path. If no patch is available, consider disabling or restricting access to the affected subsystem and monitor for exploitation indicators.
