CVE-2026-43142
media: iris: gen1: Destroy internal buffers after FW releases
Description
In the Linux kernel, the following vulnerability has been resolved: media: iris: gen1: Destroy internal buffers after FW releases After the firmware releases internal buffers, the driver was not destroying them. This left stale allocations that were no longer used, especially across resolution changes where new buffers are allocated per the updated requirements. As a result, memory was wasted until session close. Destroy internal buffers once the release response is received from the firmware.
