CVE-2026-89886

In the Linux kernel, the following vulnerability has been resolved:

media: intel/ipu6: fix async notifier cleanup leak on parse error

isys_notifier_init() calls v4l2_async_nf_init() and then adds fwnode

remote subdevs in a loop with v4l2_async_nf_add_fwnode_remote(). If an

endpoint parse or add fails partway through the loop, it jumps to

err_parse and returns without calling v4l2_async_nf_cleanup(), leaking

every v4l2_async_connection already added to the notifier's waiting

list.

The register-failure path just below already cleans up correctly, and

the caller only tears the notifier down (isys_notifier_cleanup()) once

isys_notifier_init() has returned success. Clean up the notifier on the

parse error path too.
