CVE-2024-50125: Bluetooth: SCO: Fix UAF on sco_sock_timeout

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: SCO: Fix UAF on sco_sock_timeout conn->sk maybe have been unlinked/freed while waiting for sco_conn_lock so this checks if the conn->sk is still valid by checking if it part of sco_sk_list.

Security readout for executives and security teams

Plain-English summary

A Linux Bluetooth audio flaw can access a socket after its memory has been released during a connection timeout. The supplied CVSS score is 8.0, reflecting potentially serious confidentiality, integrity, and availability impact. Exposure appears limited to affected kernels where Bluetooth SCO functionality is reachable.

Executive priority

Treat this as a high-priority kernel update for Bluetooth-capable Linux fleets, particularly laptops, mobile or embedded devices, and shared environments. It is less urgent for systems without usable Bluetooth SCO exposure. Require package-level validation because the supplied version mapping is not sufficiently clear for decisions based solely on kernel version.

Technical view

CVE-2024-50125 is a CWE-416 use-after-free race in sco_sock_timeout. While code waits for sco_conn_lock, conn->sk may be unlinked and freed. The upstream correction verifies that the socket remains in sco_sk_list before using it. The supplied vector requires adjacent access, low privileges, and no user interaction.

Likely exposure

Prioritize Linux systems using affected kernels with Bluetooth enabled, especially devices supporting SCO audio connections. Internet-only exposure is not indicated by the adjacent-attack vector. The supplied affected-version data contains ambiguous entries, including "0" and duplicate hashes, so confirm distribution-specific package and backport status rather than relying only on version strings.

Exploitation context

The bundle does not identify CVE-2024-50125 as CISA KEV and provides no evidence of active exploitation. Successful exploitation is characterized as adjacent, low-complexity, low-privilege, and requiring no user interaction. The sources do not establish exploit reliability or observed attacks.

Researcher notes

The central condition is socket lifetime changing while sco_sock_timeout waits for sco_conn_lock. The correction uses sco_sk_list membership as a validity check. The bundle supports high theoretical impact through CVSS, but it does not document demonstrated code execution, exploitation in the wild, or a complete distribution-by-distribution affected-version matrix.

Mitigation direction

  • Apply the distribution kernel update incorporating the referenced Linux stable correction.
  • Reboot affected systems so the corrected kernel is actually running.
  • Consult the Linux distribution vendor when package or backport status is unclear.
  • Prioritize remediation on Bluetooth-enabled endpoints and embedded devices supporting SCO audio.

Validation and detection

  • Inventory running kernels on systems with Bluetooth hardware or SCO functionality.
  • Compare installed packages with distribution advisories and referenced upstream stable corrections.
  • Confirm the corrected kernel is running after maintenance and reboot.
  • Review kernel logs for Bluetooth or SCO failures, recognizing that clean logs do not prove safety.
