| Vector | AV: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 versions prior to 6.6.58
Description
A vulnerability in the Linux kernel has been resolved, which could lead to memory leaks. The issue is related to the bpf helpers that had ARG PTR TO {LONG,INT} as input arguments. In case of an error, the value was not zeroed, potentially causing memory leaks. The MTU helpers also had an issue where the mtu len pointer value was being written but also read. The MEM UNINIT semantics will be reworked in follow-up work to better express the intent.
Recommendations
For versions prior to 6.6.58, update to version 6.6.58 or later to resolve the issue.
As a temporary workaround, consider clearing the *mtu len on error path to prevent potential memory leaks.
