CVE-2026-97907
Published: September 29, 2026Last modified: September 29, 2026
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.
