Severity Level: Medium
Components Affected
Overview
Multiple vulnerabilities were identified in Android. A remote attacker could exploit some of these vulnerabilities to trigger elevation of privilege and sensitive information disclosure on the targeted system.
Description
A use-after-free vulnerability in the Linux kernel’s af_unix component can be exploited to achieve local privilege escalation. The unix_stream_sendpage() function tries to add data to the last skb in the peer’s recv queue without locking the queue. Thus there is a race where unix_stream_sendpage() could access an skb locklessly that is being released by garbage collection, resulting in use-after-free. We recommend upgrading past commit 790c2f9d15b594350ae9bca7b236f2b1859de02c.
In multiple methods of UserManagerService.java, there is a possible failure to persist or enforce user restrictions due to improper input validation. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is needed for exploitation.
In sendIntentSender of ActivityManagerService.java, there is a possible background activity launch due to a logic error. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.
In multiple locations, there is a possible notification listener grant to an app running in the work profile due to a logic error in the code. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is needed for exploitation.
In multiple locations, there is a possible failure to persist or enforce user restrictions due to improper input validation. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is needed for exploitation.
In multiple locations, there is a possible bypass of health data permissions due to an improper input validation. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.
In multiple locations, there is a possible permissions bypass due to improper input validation. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is needed for exploitation.
In multiple functions of NotificationManagerService.java, there is a possible way to not show a toast message when a clipboard message has been accessed. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.
In multiple locations, there is a possible out of bounds write due to a heap buffer overflow. This could lead to remote information disclosure with no additional execution privileges needed. User interaction is needed for exploitation.
