CVE-2023-52984: Linux Kernel

Medium severity, CVSS 5.5. EPSS: 0.3% chance of exploitation in the next 30 days.

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.

Affected products

• Linux Linux Kernel: from 5.10, before 5.10.168 (fixed in 5.10.168); from 5.11, before 5.15.93 (fixed in 5.15.93); from 5.16, before 6.1.11 (fixed in 6.1.11); version 6.2 only
