FKIE_CVE-2024-42224
Vulnerability from fkie_nvd - Published: 2024-07-30 08:15 - Updated: 2026-06-17 07:49
Severity
Summary
In the Linux kernel, the following vulnerability has been resolved:
net: dsa: mv88e6xxx: Correct check for empty list
Since commit a3c53be55c95 ("net: dsa: mv88e6xxx: Support multiple MDIO
busses") mv88e6xxx_default_mdio_bus() has checked that the
return value of list_first_entry() is non-NULL.
This appears to be intended to guard against the list chip->mdios being
empty. However, it is not the correct check as the implementation of
list_first_entry is not designed to return NULL for empty lists.
Instead, use list_first_entry_or_null() which does return NULL if the
list is empty.
Flagged by Smatch.
Compile tested only.
