Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description A vulnerability in the Linux kernel has been resolved, related to the bonding driver. When a non-ethernet device is enslaved to a bond device that is itself a slave, the bond device's IFF SLAVE flag is not properly restored after an error occurs. This can lead to warnings and potential issues when trying to delete the bond device. The vulnerability was reported by syzbot and has been fixed by restoring the bond device's flags properly using the bond ether setup helper.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
