Details

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

ath11k: mhi: use mhi_sync_power_up()

If amss.bin was missing ath11k would crash during 'rmmod ath11k_pci'. The reason for that was that we were using mhi_async_power_up() which does not check any errors. But mhi_sync_power_up() on the other hand does check for errors so let's use that to fix the crash.

I was not able to find a reason why an async version was used. ath11k_mhi_start() (which enables state ATH11K_MHI_POWER_ON) is called from ath11k_hif_power_up(), which can sleep. So sync version should be safe to use here.

The\nreason for that was that we were using mhi_async_power_up() which does not\ncheck any errors. But mhi_sync_power_up() on the other hand does check for\nerrors so let\u0027s use that to fix the crash.\n\nI was not able to find a reason why an async version was used.\nath11k_mhi_start() (which enables state ATH11K_MHI_POWER_ON) is called from\nath11k_hif_power_up(), which can sleep.

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.
