Name of the Vulnerable Software and Affected Versions Android kernel

Description The issue is related to a possible use-after-free (UAF) due to a logic error in the lwis i2c device disable function of lwis device i2c.c. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.

Recommendations For Android kernel, consider applying a patch to fix the logic error in the lwis i2c device disable function as a permanent solution. As a temporary workaround, consider restricting access to the lwis i2c device disable function to minimize the risk of exploitation.
