Описание
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
audit_match_perm() to obtain the open_how::flags can result in an
oops/page-fault. This patch fixes this by using the open_how struct
that we store in the audit_context with audit_openat2_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.
Dereferencing the openat2 syscall argument in audit_match_perm() to obtain the open_how::flags can result in an oops/page-fault. This has the potential to cause a loss of Availability.
