Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
A flaw exists in the Linux kernel related to the handling of
poll interval within the bq27xxx battery driver. Specifically, the issue involves potential race conditions on device removal and unexpected modifications to poll interval when the driver is unbound through sysfs. Prior to a patch, setting poll interval to 0 aimed to prevent requeuing of a delayed work item, but this approach introduced race conditions and unexpected behavior. The fix involves using a removed attribute within the bq27xxx device info structure instead of directly manipulating poll interval. Additionally, the order of operations during device removal was adjusted to prevent a race condition where writing to /sys/module/bq27xxx battery/parameters/poll interval could requeue the delayed work item for all devices.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
