Title
media: max9286: Fix memleak in max9286_v4l2_register()
Summary
In the Linux kernel, the following vulnerability has been resolved:
media: max9286: Fix memleak in max9286_v4l2_register()
There is a kmemleak when testing the media/i2c/max9286.c with bpf mock
device:
kmemleak: 5 new suspected memory leaks (see /sys/kernel/debug/kmemleak)
unreferenced object 0xffff88810defc400 (size 256):
comm "python3", pid 278, jiffies 4294737563 (age 31.978s)
hex dump (first 32 bytes):

max9286_v4l2_register() calls v4l2_ctrl_new_std(), but won't free the
created v412_ctrl when fwnode_graph_get_endpoint_by_id() failed, which
causes the memleak. Call v4l2_ctrl_handler_free() to free the v412_ctrl.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the
vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base
model, served locally by ML-Gateway.
They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
