Name of the Vulnerable Software and Affected Versions Android kernel

Description The issue is caused by a logic error in the code, leading to a possible allocation of RWX memory in the target init function of gs101/abl/target/slider/target.c. This could result in 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 logic error in the target init function as a permanent solution. As a temporary workaround, restrict access to the target init function to minimize the risk of exploitation.
