HiCOS’ client-side citizen digital certificate component has a stack-based buffer overflow vulnerability when reading IC card due to insufficient parameter length validation for OS information. An unauthenticated physical attacker can exploit this vulnerability to execute arbitrary code, manipulate system data or terminate service.
CVE-2022-32958
A remote attacker with general user privilege can send a message to Teamplus Pro’s chat group that exceeds message size limit, to terminate other recipients’ Teamplus Pro chat process.
CVE-2022-32955
An issue was discovered in Insyde InsydeH2O with kernel 5.0 through 5.5. DMA attacks on the NvmExpressDxe buffer used by SMM and non-SMM code could cause TOCTOU race-condition issues that could lead to corruption of SMRAM and escalation of privileges. This attack can be mitigated by using IOMMU protection for the ACPI runtime memory used for the command buffer. This attack can be mitigated by copying the link data to SMRAM before checking it and verifying that all pointers are within the buffer.
CVE-2022-32954
An issue was discovered in Insyde InsydeH2O with kernel 5.1 through 5.5. DMA attacks on the SdMmcDevice buffer used by SMM and non-SMM code could cause TOCTOU race-condition issues that could lead to corruption of SMRAM and escalation of privileges. This attack can be mitigated by using IOMMU protection for the ACPI runtime memory used for the command buffer. This attack can be mitigated by copying the link data to SMRAM before checking it and verifying that all pointers are within the buffer.
