CVE-2026-97907

/// Technical description

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

Bluetooth: btrtl: Don't leak return code when parsing firmware format v2

When key_id from chip is zero, rtlbt_parse_firmware_v2() intentionally

ignores all security headers. However, the implementation simply breaks

from a switch statement and leaks uninitialized return code `rc' (if the

first section is a security one) or the previous section's `rc'.

Fix it by really skipping a loop with `continue'. For consistency and

readability, also do the same for the default case.

/// 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.
