CVE-2021-39719

Name of the Vulnerable Software and Affected Versions Android kernel

Description The issue is related to a possible out of bounds write due to an integer overflow in the lwis top register io function of lwis device top.c. This could lead to local escalation of privilege, requiring System execution privileges. No user interaction is needed for exploitation.

Recommendations For Android kernel, consider applying a patch to fix the integer overflow issue in the lwis top register io function as a permanent solution. As a temporary workaround, restrict access to the lwis device top.c module to minimize the risk of exploitation.
