| CVE ID | Description | Base Score | Vector |
|---|---|---|---|
| CVE‑2021‑1106 | NVIDIA Linux kernel distributions contain a vulnerability in nvmap, where writes may be allowed to read-only buffers, which may result in escalation of privileges, denial of service, information disclosure, or data tampering. |
7.8 | AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H |
| CVE‑2021‑1107 | NVIDIA Linux kernel distributions contain a vulnerability in nvmap NVMAP_IOC_WRITE* paths, where improper access controls may lead to code execution, denial of service, or compromised integrity of system components. |
7.8 | AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H |
| CVE‑2021‑34401 | NVIDIA Linux kernel distributions contain a vulnerability in nvmap NVGPU_IOCTL_CHANNEL_SET_ERROR_NOTIFIER, where improper access control may lead to code execution, compromised integrity, or denial of service. |
7.8 | AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H |
| CVE‑2021‑1108 | NVIDIA Linux kernel distributions contain a vulnerability in FuSa Capture (VI/ISP), where integer underflow caused by lack of input validation may lead to complete denial of service, partial integrity, and serious confidentiality loss for all processes in the system. | 7.3 | AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:L/A:H |
| CVE‑2021‑34402 | NVIDIA Tegra kernel driver contains a vulnerability in NVIDIA NVDEC, where a user with high privileges might be able to read from or write to a memory location that is outside the intended boundary of the buffer, which may lead to denial of service, Information disclosure, loss of Integrity, or possible escalation of privileges. | 6.7 | AV:L/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H |
| CVE‑2021‑34403 | NVIDIA Linux distributions contain a vulnerability in nvmap ioctl, which allows any user with a local account to exploit a use-after-free condition, leading to code privilege escalation, loss of confidentiality and integrity, or denial of service. | 7.8 | AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H |
| CVE‑2021‑34404 | Android images for T210 provided by NVIDIA contain a vulnerability in BROM, where failure to limit access to AHB-DMA when BROM fails may allow an unprivileged attacker with physical access to cause denial of service or impact integrity and confidentiality beyond the security scope of BROM. |
7.1 |
AV:P/AC:H/PR:N/UI:N/S:C/C:H/I:H/A:H |
| CVE‑2021‑34405 | NVIDIA Linux distributions contain a vulnerability in TrustZone’s TEE_Malloc function, where an unchecked return value causing a null pointer dereference may lead to denial of service. |
5.5 | AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H |
| CVE‑2021‑1112 | NVIDIA Linux kernel distributions contain a vulnerability in nvmap, where a null pointer dereference may lead to denial of service. |
5.5 | AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H |
| CVE‑2021‑34406 | NVIDIA Tegra kernel driver contains a vulnerability in NVHost, where a specific race condition can lead to a null pointer dereference, which may lead to a system reboot. | 4.7 | AV:L/AC:H/PR:L/UI:N/S:U/C:N/I:N/A:H |
