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： wifi: rtlwifi: pci: 修复 rtl_pci_probe() 中的错误路径 在 rtl_pci_probe() 函数的最后一个错误处理路径中，由于使用了错误的 goto 标签，导致清理函数被跳过。此外，之前成功调用的 rtl_init_rfkill()、ieee80211_register_hw() 和 rtl_debug_add_one() 函数需要进行回滚操作。通过更新标签并在最后一个错误处理路径中添加相应的清理函数，修复了此问题。

Vulnerability Title
wifi: rtlwifi: pci: fix error path in rtl_pci_probe()
Source: CVE Program / CVE List V5
Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved:
wifi: rtlwifi: pci: fix error path in rtl_pci_probe()
In the last error path in rtl_pci_probe(), the cleanup functions are
skipped due to a wrong goto label. Moreover, the successful call to
rtl_init_rfkill(), ieee80211_register_hw(), rtl_debug_add_one() have to
be reverted. Fix this issue by updating the labels and adding the
relevant cleanup functions to the last error path.
