- Details
-
Copyfromuser on 64-bit versions of the Linux kernel does not implement the _uaccessbeginnospec allowing a user to bypass the "accessok" check and pass a kernel pointer to copyfromuser(). This would allow an attacker to leak information. We recommend upgrading beyond commit 74e19ef0ff8061ef55957c3abd71614ef0f42f47
