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 skb to mamac function of networking.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 to fix the integer overflow issue in the skb to mamac function as a permanent solution. As a temporary workaround, restrict access to the skb to mamac function to minimize the risk of exploitation.
