Name of the Vulnerable Software and Affected Versions Android kernel

Description The issue is related to a race condition in the emulation proc handler function of armv8 deprecated.c, which could lead to memory corruption. This may result in local escalation of privilege without requiring additional execution privileges. User interaction is not necessary for exploitation. The vulnerability could allow an attacker to access confidential data, compromise its integrity, and cause a denial of service.

Recommendations For Android kernel, consider applying a patch from the upstream kernel to resolve the issue. As a temporary workaround, restricting access to the emulation proc handler function may help minimize the risk of exploitation.
