VectorAV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)
Description A memory leak issue has been identified in the Linux kernel when GSO is enabled. The issue occurs because the skb is mapped to the EXT descriptor instead of the LS descriptor when the number of fragments is zero, preventing it from being freed. This leads to a memory leak. The estimated number of potentially affected devices worldwide is not available. There is no information about real-world incidents where this issue was exploited.
Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
