CVE-2026-68333 in Linux
الملخص
بحسب MITRE • 10/08/2026
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.
