| 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 (affected versions not specified)
Description
The issue is related to a potential leak in the
nfp tunnel add shared mac() function. The ida simple get() function returns an id between 0 and NFP MAX MAC INDEX inclusive, and NFP MAX MAC INDEX (0xff) is a valid id. To ensure the error handling path works correctly, the 'invalid' value for ida idx should not be in the 0..NFP MAX MAC INDEX range, inclusive, so it is set to -1. This vulnerability may allow an attacker to cause a denial of service.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
