Severity

Medium

Analysis Summary

CVE‑2022‑28193, CVSS 7.3

NVIDIA Jetson Linux Driver Package contains a vulnerability in the Cboot module tegrabl_cbo.c, where insufficient validation of untrusted data may allow a local attacker to cause a memory buffer overflow, which may lead to code execution, loss of integrity, limited denial of service, and some impact to confidentiality.

CVE‑2022‑28194, CVSS 7.3

NVIDIA Jetson Linux Driver Package contains a vulnerability in the Cboot module tegrabl_cbo.c, where, if TFTP is enabled, a local attacker can cause a memory buffer overflow, which may lead to code execution, loss of Integrity, limited denial of service, and some impact on confidentiality.

CVE‑2022‑28195, CVSS 5.7

NVIDIA Jetson Linux Driver Package contains a vulnerability in the Cboot ext4_read_file function, where insufficient validation of untrusted data may allow a highly privileged local attacker to cause an integer overflow, which may lead to code execution, escalation of privileges, limited denial of service, and some impact to confidentiality and integrity.

CVE‑2022‑28196, CVSS 5.7

NVIDIA Jetson Linux Driver Package contains a vulnerability in the Cboot blob_decompress function, where insufficient validation of untrusted data may allow a local attacker to cause a memory buffer overflow, which may lead to code execution, limited loss of Integrity, and limited denial of service.

CVE‑2022‑28197, CVSS 5.0

NVIDIA Jetson Linux Driver Package contains a vulnerability in the Cboot ext4_mount function, where Insufficient validation of untrusted data may allow a highly privileged local attacker to cause an integer overflow. This difficult-to-exploit vulnerability may lead to code execution, escalation of privileges, limited denial of service, and some impact on confidentiality and integrity.
