- Summary
- CVE-2024-42224 affecting package kernel for versions less than 6.6.43.1-7
- Details
-
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.
