Name of the Vulnerable Software and Affected Versions
Android kernel
Description
The issue is related to a possible use after free due to improper locking in the blk mq queue tag busy iter function of blk-mq-tag.c. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not required for exploitation.
Recommendations
For Android kernel, consider applying a patch that properly addresses the locking issue in the blk mq queue tag busy iter function to prevent use after free.
