Descriptions
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.
