Overview

CVE-2026-53310 is a medium-severity vulnerability. It was published on June 26, 2026 and has a CVSS 3.1 base score of 5.5 (MEDIUM).

This vulnerability has a CVSS 3.1 base score of 5.5, rated MEDIUM. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical description

In the Linux kernel, the following vulnerability has been resolved:

soc/tegra: cbb: Fix cross-fabric target timeout lookup

When a fabric receives an error interrupt, the error may have

occurred on a different fabric. The target timeout lookup was using

the wrong base address (cbb->regs) with offsets from a different

fabric's target map, causing a kernel page fault.

Unable to handle kernel paging request at virtual address ffff80000954cc00

pc : tegra234_cbb_get_tmo_slv+0xc/0x28

Call trace:

tegra234_cbb_get_tmo_slv+0xc/0x28

print_err_notifier+0x6c0/0x7d0

tegra234_cbb_isr+0xe4/0x1b4

Add tegra234_cbb_get_fabric() to look up the correct fabric device

using fab_id, and use its base address for accessing target timeout

registers.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
