Name of the Vulnerable Software and Affected Versions Android kernel

Description The issue is related to improper locking in the sdcardfs create and sdcardfs mkdir functions of inode.c, which could lead to memory corruption. This might allow for local escalation of privilege without needing additional execution privileges. User interaction is not required for exploitation.

Recommendations For Android kernel, consider applying a patch that fixes the improper locking issue in the sdcardfs create and sdcardfs mkdir functions as a permanent solution.
