CVE-2022-49543

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description An issue exists in the ath11k driver where a warning is triggered in the mhi pm disable transition() function during device recovery. This occurs because mhi deassert dev wake() is called via mhi device put() without a preceding call to mhi assert dev wake() from mhi device get sync(). This state is caused by a check for the pm state of the MHI, which remains in a non-normal state until recovery is complete, resulting in a non-zero dev wake value. Additionally, the ath11k pci write32() function in the drivers/net/wireless/ath/ath11k/pci.c module may fail to correctly release resources, which could potentially lead to a denial of service.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
