CVE-2021-39715

Status: ModifiedMedium (4.4)—

In __show_regs of process.c, there is a possible leak of kernel memory and addresses due to log information disclosure. This could lead to local information disclosure with System execution privileges needed. User interaction is not needed for exploitation.Product: AndroidVersions: Android kernelAndroid ID: A-178379135References: Upstream kernel

CVSS
