CVE-2026-98008: Undefined Security Weakness

In the Linux kernel, the following vulnerability has been resolved: net: macb: fix NULL pointer dereference on unbind with fixed-link When the device tree describes a fixed-link and has no "mdio" child node, macbmiiinit returns early without allocating the MDIO bus, leaving bp-miibus as NULL. Two...

CVE-2026-97973: Undefined Security Weakness

In the Linux kernel, the following vulnerability has been resolved: net: macb: destroy the phylink instance on the probe error path macbmiiinit creates a phylink instance on both of its success paths, but the probe unwind frees the netdev without destroying it, so a failing macballoctieoff or...

CVE-2026-97972: Undefined Security Weakness

In the Linux kernel, the following vulnerability has been resolved: net: macb: put the "mdio" child node reference on success macbmiiinit holds the reference returned by ofgetchildbyname for macbmdiobusregister and drops it only on the error paths, so every successful probe leaks a node reference...
