GHSA-684M-V6V9-3H53

Vulnerability from github – Published: 2024-05-01 06:31 – Updated: 2024-06-03 18:55

Details

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

r8169: fix LED-related deadlock on module removal

Binding devm_led_classdev_register() to the netdev is problematic because on module removal we get a RTNL-related deadlock. Fix this by avoiding the device-managed LED functions.

Note: We can safely call led_classdev_unregister() for a LED even if registering it failed, because led_classdev_unregister() detects this and is a no-op in this case.

Severity

7.8 (High)
