| Vector | AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H |
Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
The issue is related to a potential double-free in the
fs any create groups function. When kcalloc() for ft->g succeeds but kvzalloc() for in fails, fs any create groups() will free ft->g. However, its caller fs any create table() will free ft->g again through calling mlx5e destroy flow table(), which will lead to a double-free. This can be fixed by setting ft->g to NULL in fs any create groups(). The 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.
