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.
