NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-64k-debug-devel-matched package and not the kernel-64k-debug-devel-matched package as distributed by RHEL.

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

net: phy: dp83822: Fix null pointer access on DP83825/DP83826 devices

The probe() function is only used for the DP83822 PHY, leaving the private data pointer uninitialized for the smaller DP83825/26 models. While all uses of the private data structure are hidden in 82822 specific callbacks, configuring the interrupt is shared across all models. This causes a NULL pointer dereference on the smaller PHYs as it accesses the private data unchecked. Verifying the pointer avoids that.
