## Known Issues

**Table 5** Known issues

| Issue No.| Description| Impact| To Be Resolved By| 
| -------- | -------- | -------- | -------- |
| I8PEOF | A system freeze may occur due to LIFECYCLE_TIMEOUT of the com.ohos.mms process. As such, a white screen is displayed.| This issue occurs occasionally. It can be resolved by restarting the device. The impact is controllable.| January 15| 
| I8QET3 | A C++ crash may occur in libbluetooth_server.z.so of the OS_IPC_10_25363 thread of the bluetooth_servi process. As such, the Bluetooth service is abnormal.| This issue occurs occasionally. It can be automatically restored, and users are unaware of the exception.| February 28| 
| I8QH9S | A C++ crash may occur in libnative_appdatafwk.z.so of the os.settingsdata thread of the com.ohos.settingsdata process. As such, the background data management process stops.| This issue occurs rarely. The process automatically restarts when a new access request is received. Users are unaware of the exception.| January 15| 
| I8QNI7 | A system freeze may occur due to SERVICE_BLOCK of the foundation process.| This issue occurs rarely. Users are unaware of the exception.| February 28| 
| I8QSZ1 | An app freeze occurs in libsamgr_proxy.z.so of the com.ohos.systemui process, due to THREAD_BLOCK_6S.| This issue occurs occasionally. There is an extremely low probability that the system UI does not respond when the user slides down, and the user has to turn on and off Bluetooth on the Settings screen or restart the phone. The impact is controllable.| February 28| 
| Vulnerabilities (such as I7TYTF) in 43 open-source components| 43 open-source component vulnerabilities, such as protection_fault in the errseq_set function of the kernel| The vulnerabilities are being analyzed and will be resolved based on the vulnerability management process SLA of the community.| By vulnerability SLA| 
| I78THF | The maligpu version in the RK3568 kernel patch is too old (11.29), and a large number of CVE vulnerabilities are not fixed.| The GPU Mali driver of RK3568 has many unfixed CVE vulnerabilities, such as CVE-2021-28663 and CVE-2021-39793. These vulnerabilities can be exploited to obtain the kernel UAF and escalate privileges.| February 10| 
| I83D6I | If Bluetooth is repeatedly enabled and disabled in Settings, there is a possibility that an app freeze occurs.| This issue occurs occasionally. It can be resolved by restarting the device. The impact is controllable.| February 28| 
| I827LU | Memory leakage occurs when Bluetooth is enabled and disabled repeatedly in Settings. A memory leak of 15 MB occurs within one hour.| A memory leak of 8.3 KB occurs for one Bluetooth enable/disable operation. This issue can be resolved by restarting the device. The impact is controllable.| February 28| 
| I82V2W | Memory leakage occurs when Bluetooth is repeatedly enabled and disabled in Settings. The memory usage of Settings increases to 180 MB within one hour.| You are advised to use the protocol stack of the Bluetooth module built in the chip or hardware to avoid this issue.<br>A memory leak of 0.2 MB occurs for one Bluetooth enable/disable operation. The issue can be resolved by re-opening Settings. The impact is controllable.<br>You are advised to use the protocol stack of the Bluetooth module built in the chip or hardware to avoid this issue.| February 28|
