[PATCH v6.1 0/2] ksmbd: fix potencial out-of-bounds when buffer offset is invalid

Posted by Vamsi Krishna Brahmajosyula 1 week ago

The dependent patch (slab-out-of-bounds) is backported from 6.7 instead of 6.6.
In the 6.6 commit (9e4937cbc150f), the upstream commit id points to an incorrect one.

Looks good to me:)
Thanks for backporting ksmbd's fixes to stable 6.1 kernel.
