CVE-2026-89883
HIGH
Published Sep 16, 2026
Modified Sep 16, 2026
Description
In the Linux kernel, the following vulnerability has been resolved: media: rc: sunxi-cir: Unregister rc device on probe failure After rc_register_device() succeeds, later probe failures must undo the registration with rc_unregister_device(). The current error path jumps to the allocation cleanup label and only calls rc_free_device(), leaving the rc device registration and resources created by rc_register_device() behind. Add a registered-device unwind label for the IRQ lookup, IRQ request, and hardware initialization failure paths. Keep rc_free_device() for failures before rc_register_device() succeeds.

Frequently Asked Questions
What is CVE-2026-89883? +
In the Linux kernel, the following vulnerability has been resolved:
media: rc: sunxi-cir: Unregister rc device on probe failure
After rc_register_device() succeeds, later probe failures must undo the
registration with rc_unregister_device(). The current error path jumps to
the allocation cleanup label and only calls rc_free_device(), leaving the
rc device registration and resources created by rc_register_device()
behind.
Add a registered-device unwind label for the IRQ lookup, IRQ request, and
hardware initialization failure paths. Keep rc_free_device() for failures
before rc_register_device() succeeds. It has a CVSS v3.1 base score of 7.8 (HIGH).
How severe is CVE-2026-89883? +
CVE-2026-89883 has a CVSS v3.1 score of 7.8 out of 10, rated HIGH. This is a high-severity vulnerability that should be prioritized for patching.
