Critical Vulnerability in Samsung Devices

A serious security issue (CVE-2024-49415) has been found in Samsung smartphones, which could let hackers take control of the device without any action from the user. This problem affects phones running Android 12, 13, and 14.Samsung has fixed the issue in their December 2024 security update.

 

Key Details

  • CVE ID: CVE-2024-49415
  • Severity: Critical rated by Samsung
  • Affected Components: Monkey's Audio (APE) decoder, specifically the libsaped.so library
  • Impacted Devices: Samsung Galaxy S23, S24, and potentially other models
  • Vulnerability Type: Out-of-bounds write

 

The vulnerability stems from an out-of-bounds write issue in the saped_rec function within the libsaped.so library. This function writes to a DMA buffer allocated by the C2 media service, which has a fixed size of 0x120000 bytes. However, specially crafted APE files with large blocksperframe sizes can cause substantial buffer overflow.

 

Exploitation Scenario:
The vulnerability is especially concerning because it can be triggered remotely via Rich Communication Services (RCS) messaging, which is enabled by default on Samsung S24 devices. This allows attackers to exploit the vulnerability without any user interaction, increasing the likelihood of successful exploitation.

 

Affected Versions:

Take Action

Protect yourself
  • Apply the December 2024 Samsung security update immediately.
  • Ensure that automatic updates are enabled on devices to receive future patches promptly.
