| CVE | 摘要 | 来源 | 最高 CVSS | EPSS % | 公开时间 | 更新时间 |
|---|---|---|---|---|---|---|
| CVE-2021-38789 | Allwinner R818 SoC Android Q SDK V1.0 is affected by an incorrect access control vulnerability that does not check the caller's permission, in which a third-party app could change system settings. | [email protected] | 7.5 | 0.34% | 2022-01-19 | 2024-11-21 |
| CVE-2021-38788 | The Background service in Allwinner R818 SoC Android Q SDK V1.0 is used to manage background applications. Malicious apps can use the interface provided by the service to set the number of applications allowed to run in the background to 0 and add themselves to the whitelist, so that once other applications enter the background, they will be forcibly stopped by the system, causing a denial of service. | [email protected] | 7.5 | 0.79% | 2022-01-19 | 2024-11-21 |
| CVE-2021-38787 | There is an integer overflow in the ION driver "/dev/ion" of Allwinner R818 SoC Android Q SDK V1.0 that could use the ioctl cmd "COMPAT_ION_IOC_SUNXI_FLUSH_RANGE" to cause a system crash (denial of service). | [email protected] | 7.5 | 0.79% | 2022-01-19 | 2024-11-21 |
| CVE-2021-38786 | There is a NULL pointer dereference in media/libcedarc/vdecoder of Allwinner R818 SoC Android Q SDK V1.0, which could cause a media crash (denial of service). | [email protected] | 7.5 | 0.79% | 2022-01-19 | 2024-11-21 |
| CVE-2021-38785 | There is a NULL pointer deference in the Allwinner R818 SoC Android Q SDK V1.0 camera driver /dev/cedar_dev that could use the ioctl cmd IOCTL_GET_IOMMU_ADDR to cause a system crash. | [email protected] | 7.5 | 0.78% | 2022-01-18 | 2024-11-21 |
| CVE-2021-38784 | There is a NULL pointer dereference in the syscall open_exec function of Allwinner R818 SoC Android Q SDK V1.0 that could executable a malicious file to cause a system crash. | [email protected] | 7.5 | 0.57% | 2022-01-18 | 2024-11-21 |
| CVE-2021-38783 | There is a Out-of-Bound Write in the Allwinner R818 SoC Android Q SDK V1.0 camera driver "/dev/cedar_dev" through iotcl cmd IOCTL_SET_PROC_INFO and IOCTL_COPY_PROC_INFO, which could cause a system crash or EoP. | [email protected] | 7.5 | 0.77% | 2022-01-18 | 2024-11-21 |
