| Vector | AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H |
Name of the Vulnerable Software and Affected Versions:
Linux kernel (affected versions not specified)
Description:
The issue is related to a potential use-after-free error in the phylib component of the Linux kernel. This error occurs because the
phy device reset(phydev) function is called after the put device() call in phy detach(), which might cause the phydev to be freed prematurely. The comment before the put device() call indicates that the phydev might go away with put device(). To fix this, the phy device reset() function should be called before put device(). The vulnerability may allow an attacker to elevate privileges in the system.Recommendations:
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
