| CVE | 摘要 | 來源 | 最高 CVSS | EPSS % | 公開時間 | 更新時間 |
|---|---|---|---|---|---|---|
| CVE-2021-41614 | An issue was discovered in the controller unit of the OpenRISC mor1kx processor. The read/write access permissions to the Exception Program Counter Register (EPCR) are not implemented correctly. User programs from an unauthorized privilege level can make read/write accesses to EPCR. | [email protected] | 7.8 | 0.16% | 2023-04-18 | 2026-06-17 |
| CVE-2021-41613 | An issue was discovered in the controller unit of the OpenRISC mor1kx processor. The write logic of Exception Effective Address Register (EEAR) is not implemented correctly. User programs from authorized privilege levels will be unable to write to EEAR. | [email protected] | 4.3 | 0.41% | 2023-04-18 | 2026-06-17 |
| CVE-2021-41612 | An issue was discovered in the ALU unit of the OpenRISC mor1kx processor. The carry flag is not being updated correctly for the subtract instruction, which results in an incorrect value of the carry flag. Any software that relies on this flag may experience corruption in execution. | [email protected] | 8.8 | 1.15% | 2023-04-18 | 2026-06-17 |
| CVE-2021-40507 | An issue was discovered in the ALU unit of the OR1200 (aka OpenRISC 1200) processor 2011-09-10 through 2015-11-11. The overflow flag is not being updated correctly for the subtract instruction, which results in an incorrect value in the overflow flag. Any software that relies on this flag may experience corruption in execution. | [email protected] | 9.8 | 0.69% | 2023-04-18 | 2026-06-17 |
| CVE-2021-40506 | An issue was discovered in the ALU unit of the OR1200 (aka OpenRISC 1200) processor 2011-09-10 through 2015-11-11. The overflow flag is not being updated for the msb and mac instructions, which results in an incorrect value in the overflow flag. Any software that relies on this flag may experience corruption in execution. | [email protected] | 9.8 | 0.69% | 2023-04-18 | 2026-06-17 |
