GHSA-2RFF-FCFM-WV2Q
Vulnerability from github – Published: 2025-09-05 18:31 – Updated: 2025-11-26 00:30In the Linux kernel, the following vulnerability has been resolved:
net: ftgmac100: fix potential NULL pointer access in ftgmac100_phy_disconnect
After the call to phy_disconnect() netdev->phydev is reset to NULL. So fixed_phy_unregister() would be called with a NULL pointer as argument. Therefore cache the phy_device before this call.
