CVE-2026-68333

Not scored yetLast modified Aug 19, 2026

Description

In the Linux kernel, the following vulnerability has been resolved:

dpaa2-switch: put MAC endpoint device on disconnect

fsl_mc_get_endpoint() returns the MAC endpoint device with a reference taken through device_find_child(). The switch port connect path stores that device in mac->mc_dev and keeps it for the lifetime of the connected MAC object.

However, the disconnect path only closes the MAC and frees the dpaa2_mac object. It does not drop the endpoint device reference stored in mac->mc_dev, so every successful connect leaks that device reference when the MAC is later disconnected.

Drop the endpoint device reference before freeing the dpaa2_mac object.
