Details

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

ASoC: rt5645: Fix errorenous cleanup order

There is a logic error when removing rt5645 device as the function rt5645_i2c_remove() first cancel the &rt5645->jack_detect_work and delete the &rt5645->btn_check_timer latter. However, since the timer handler rt5645_btn_check_callback() will re-queue the jack_detect_work, this cleanup order is buggy.

That is, once the del_timer_sync in rt5645_i2c_remove is concurrently run with the rt5645_btn_check_callback, the canceled jack_detect_work will be rescheduled again, leading to possible use-after-free.

This patch fix the issue by placing the del_timer_sync function before the cancel_delayed_work_sync.

Severity

7.8 (High)

However, since the timer\nhandler rt5645_btn_check_callback() will re-queue the jack_detect_work,\nthis cleanup order is buggy.\n\nThat is, once the del_timer_sync in rt5645_i2c_remove is concurrently\nrun with the rt5645_btn_check_callback, the canceled jack_detect_work\nwill be rescheduled again, leading to possible use-after-free.\n\nThis patch fix the issue by placing the del_timer_sync function before\nthe cancel_delayed_work_sync."

Detection rules are retrieved from Rulezet.

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.
