CVE-2022-50826: ipu3-imgu: Fix NULL pointer dereference in imgu_subdev_set_selection()

In the Linux kernel, the following vulnerability has been resolved: ipu3-imgu: Fix NULL pointer dereference in imgu_subdev_set_selection() Calling v4l2_subdev_get_try_crop() and v4l2_subdev_get_try_compose() with a subdev state of NULL leads to a NULL pointer dereference. This can currently happen in imgu_subdev_set_selection() when the state passed in is NULL, as this method first gets pointers to both the "try" and "active" states and only then decides which to use. The same issue has been addressed for imgu_subdev_get_selection() with commit 30d03a0de650 ("ipu3-imgu: Fix NULL pointer dereference in active selection access"). However the issue still persists in imgu_subdev_set_selection(). Therefore, apply a similar fix as done in the aforementioned commit to imgu_subdev_set_selection(). To keep things a bit cleaner, introduce helper functions for "crop" and "compose" access and use them in both imgu_subdev_set_selection() and imgu_subdev_get_selection().

Security readout for executives and security teams

Plain-English summary

This CVE is a Linux kernel NULL pointer dereference in the ipu3-imgu media driver. Affected systems could crash or behave unexpectedly when specific selection handling reaches this bug. The source bundle does not provide CVSS, CWE, attack requirements, or confirmed business impact.

Executive priority

Track and patch through normal kernel maintenance unless your fleet depends on ipu3-imgu media functionality. Escalate if vendor advisories later assign meaningful severity or identify practical exploitation paths.

Technical view

imgu_subdev_set_selection() could call v4l2_subdev_get_try_crop() and v4l2_subdev_get_try_compose() with a NULL subdev state, causing a NULL pointer dereference. The fix mirrors prior get_selection handling by using helper functions for crop and compose state access.

Likely exposure

Exposure appears limited to Linux kernels using the ipu3-imgu driver and the affected V4L2 subdevice selection path. The source lists Linux as affected across versions including 5.14, 5.15.87, 6.0.18, 6.1.4, and 6.2, but does not describe distribution-specific packages.

Exploitation context

The source bundle does not indicate active exploitation, and KEV is false. It also does not provide exploitability details, privilege requirements, or remote attack evidence. Treat this as a kernel stability risk until vendor advisories clarify severity.

Researcher notes

Evidence is limited to the CVE description and Linux stable commit references. The flaw is a NULL dereference in set_selection state handling, related to an earlier get_selection fix. No CVSS, CWE, proof of exploitation, or precise distro remediation data is included.

Mitigation direction

  • Apply the relevant Linux stable kernel update containing the referenced fixes.
  • Check your Linux distribution advisory for backported kernel package status.
  • Prioritize systems where ipu3-imgu support is enabled or camera/media workloads are present.
  • If patching is delayed, review vendor guidance for safe driver exposure reduction.

Validation and detection

  • Inventory kernel versions and compare them with vendor fixed package guidance.
  • Confirm whether the ipu3-imgu driver is built, loaded, or required.
  • Review kernel changelogs for the referenced stable commits.
  • Run normal regression testing for camera and media workloads after updating.
