CVE-2023-52459: media: v4l: async: Fix duplicated list deletion

In the Linux kernel, the following vulnerability has been resolved: media: v4l: async: Fix duplicated list deletion The list deletion call dropped here is already called from the helper function in the line before. Having a second list_del() call results in either a warning (with CONFIG_DEBUG_LIST=y): list_del corruption, c46c8198->next is LIST_POISON1 (00000100) If CONFIG_DEBUG_LIST is disabled the operation results in a kernel error due to NULL pointer dereference.

Security readout for executives and security teams

Plain-English summary

CVE-2023-52459 is a Linux kernel bug in the media V4L async subsystem. A duplicate list deletion can corrupt kernel list state and may lead to a kernel error through NULL pointer dereference. The public record does not provide CVSS, CWE, or confirmed exploitation evidence.

Executive priority

Track this through normal kernel patch management unless media-enabled Linux systems are business-critical. Escalate if your vendor rates it higher or if exposed systems show kernel crashes linked to this subsystem.

Technical view

The issue is a duplicated list_del() after a helper already removes the entry. With CONFIG_DEBUG_LIST enabled, the kernel warns about list_del corruption. Without that debug option, the same path can produce a NULL pointer dereference. The record identifies Linux kernel impact and stable fix commits.

Likely exposure

Exposure is limited to systems running affected Linux kernel versions that include the vulnerable media V4L async code path. The bundle does not identify distributions, devices, CPEs, or whether typical server configurations are reachable.

Exploitation context

No source in the bundle states active exploitation, and KEV is false. The trigger conditions and attacker prerequisites are not described. Treat this as a kernel reliability and potential denial-of-service concern until vendor advisories clarify reachability.

Researcher notes

The key evidence is the upstream fix description: duplicated deletion after a helper call. The source bundle lacks CVSS, CWE, exploitability analysis, and precise distro package status, so validation should focus on kernel provenance and backported commits.

Mitigation direction

  • Check your Linux distribution advisory for CVE-2023-52459.
  • Update to a kernel containing the referenced stable fix commits.
  • Prioritize systems using camera, video capture, or media V4L functionality.
  • If updates are unavailable, follow vendor guidance for temporary risk reduction.

Validation and detection

  • Inventory Linux kernel versions across affected systems.
  • Confirm whether distro kernels include backports for the referenced fixes.
  • Review kernel logs for list_del corruption or NULL pointer dereference events.
  • Verify whether media V4L async components are built, loaded, or used.
