- audit: don't deref the syscall args when checking the openat2 open_how::flags
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
audit: don't deref the syscall args when checking the openat2 open_how::flags
As reported by Jeff, dereferencing the openat2 syscall argument in auditmatchperm() to obtain the openhow::flags can result in an oops/page-fault. This patch fixes this by using the openhow struct that we store in the auditcontext with auditopenat2_how().
Independent of this patch, Richard Guy Briggs posted a similar patch to the audit mailing list roughly 40 minutes after this patch was posted.
