CVE-2026-43151 Details
Description
In the Linux kernel, the following vulnerability has been resolved: Revert "media: iris: Add sanity check for stop streaming" This reverts commit ad699fa78b59241c9d71a8cafb51525f3dab04d4. Revert the check that skipped stop_streaming when the instance was in IRIS_INST_ERROR, as it caused multiple regressions: 1. Buffers were not returned to vb2 when the instance was already in error state, triggering warnings in the vb2 core because buffer completion was skipped. 2. If a session failed early (e.g. unsupported configuration), the instance transitioned to IRIS_INST_ERROR. When userspace attempted to stop streaming for cleanup, stop_streaming was skipped due to the added check, preventing proper teardown and leaving the firmware in an inconsistent state.
A vulnerability exists in the Linux kernel's media subsystem, specifically within the IRIS driver. This issue arises from the reversion of a sanity check intended to manage the stop streaming process. The vulnerability is present in the stable version of the Linux kernel. The removed check allowed the streaming process to be halted even when the instance was in an error state, leading to several regressions. Notably, buffers were not returned to the vb2 queue when the instance was already in an error state, causing warnings in the vb2 core due to skipped buffer completions. Additionally, if a session failed early, the instance would enter an error state. When userspace tried to stop streaming for cleanup, the process was skipped, preventing proper teardown and leaving the firmware in an inconsistent state.
Users can apply the latest patch available in the Linux kernel stable tree to address this vulnerability.
