CVE-2023-52984

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...

CVE-2023-52984

CVE-2023-52984 affects the Linux kernel PHY code for DP83822 family: DP83825/DP83826 devices can dereference a NULL private data pointer because probe() initializes only the DP83822 path and interrupt setup is shared. The fix adds a NULL-pointer check/verifies the pointer before use, preventing t...
