CVE-2026-53044

A flaw was found in the Linux kernel. An out-of-bounds access vulnerability exists in the soc/tegra: cbb fabric lookup tables due to incorrect array size usage. This issue could allow a local attacker to cause a denial of service (DoS) or potentially lead to information disclosure.

Red Hat has evaluated this issue as having a Moderate severity impact because successful exploitation requires local authenticated access and is strictly limited to deployments running on specialized NVIDIA Tegra hardware. Standard enterprise server platforms are unaffected as they do not load or utilize this SoC-specific fabric interconnect driver. On affected Tegra-based environments, a local unprivileged user could trigger target timeout lookups to cause a system crash or read out-of-bounds kernel memory.

The CVSS score(s) listed for this vulnerability do not reflect the associated product's status, and are included for informational purposes to better understand the severity of this vulnerability.

Mitigation for this issue is either not available or the currently available options don't meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
