# samsung android: Kernel pointers are printed in the log file prior to SMR May-2023 Release 1 allows a privileged local attacker to…

Samsung mobile devices on Android 11, 12, and 13 write sensitive information into a log file. A privileged local attacker can use that leaked data to bypass address space layout randomization (ASLR).

_Summary, check and fix written by a model from the sources; labelled as such._

## Affected

- vendor:Samsung Mobile Devices affected ? fixed ?
- vendor:samsung android affected = 11.0 fixed ?
- vendor:samsung android affected = 12.0 fixed ?
- vendor:samsung android affected = 13.0 fixed ?

## Fix

Apply the Samsung security update for affected devices per vendor instructions; the specific patch level is unknown from the sources.

## From the sources

Samsung mobile devices running Android 11, 12, and 13 contain an insertion of sensitive information into log file vulnerability that allows a privileged, local attacker to conduct an address space layout randomization (ASLR) bypass.

CISA required action: Apply updates per vendor instructions.
