NVD Description

Note: Versions mentioned in the description apply only to the upstream kfreebsd-10 package and not the kfreebsd-10 package as distributed by Debian. See How to fix? for Debian:10 relevant fixed versions and status.

In FreeBSD 12.2-STABLE before r368969, 11.4-STABLE before r369047, 12.2-RELEASE before p3, 12.1-RELEASE before p13 and 11.4-RELEASE before p7 several file systems were not properly initializing the d_off field of the dirent structures returned by VOP_READDIR. In particular, tmpfs(5), smbfs(5), autofs(5) and mqueuefs(5) were failing to do so. As a result, eight uninitialized kernel stack bytes may be leaked to userspace by these file systems.
