Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.
在 Linux 内核中，已修复以下漏洞： 蓝牙：btrtl：解析固件格式 v2 时不应泄露返回值 当芯片中的 key_id 为零时，rtlbt_parse_firmware_v2() 会故意忽略所有安全头信息。然而，当前的实现只是从 switch 语句中 break，导致未初始化的返回值 （如果第一个部分是安全部分）或前一个部分的 被泄露。 通过正确使用 来跳过循环来修复此问题。为了保持一致性和提高可读性，也对 default 分支执行相同的操作。

Vulnerability Title
Bluetooth: btrtl: Don't leak return code when parsing firmware format v2
Source: CVE Program / CVE List V5
Vulnerability 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.
