CVE-2025-38148net: phy: mscc: Fix memory leak when using one step timestamping
Medium 5.5
In plain English
A medium-severity security flaw in Linux from Linux. There are no confirmed reports of exploitation so far. The chance it is exploited in the next 30 days is estimated at 0.2% (higher than 8% of all known vulnerabilities). Fixed versions are available - upgrade the affected package.
Official description
In the Linux kernel, the following vulnerability has been resolved: net: phy: mscc: Fix memory leak when using one step timestamping Fix memory leak when running one-step timestamping. When running one-step sync timestamping, the HW is configured to insert the TX time into the frame, so there is no reason to keep the skb anymore. As in this case the HW will never generate an interrupt to say that the frame was timestamped, then the frame will never released. Fix this by freeing the frame in case of one-step timestamping.
