FreeBSD-EN-22:11.zfs Errata Notice
The FreeBSD Project
Topic: ZFS lseek(2) inconsistencies
Category: contrib
Module: zfs
Announced: 2022-03-15
Affects: FreeBSD 13.0
Corrected: 2021-12-19 15:25:26 UTC (stable/13, 13.0-STABLE)
2022-03-15 18:09:52 UTC (releng/13.0, 13.0-RELEASE-p8)

0. Revision History
v1.0 2022-05-15 -- Initial release
v1.1 2022-05-15 -- Updated Correction Details to point to fixed patch that
was missing a prerequisite in the source tree. The standalone patch
- linked in this SA is correct, only the git repo was needed updating.
+ linked in this SA is correct, only the git repo needed updating.
I. Background
ZFS is one of several filesystems available on FreeBSD. ZFS supports
many advanced features, including checksumming, transparent compression,
and snapshots.
File "holes" are used by filesystems to limit the amount of storage
space occupied by a file containing long runs of zero bytes. Rather
than filling disk blocks with zeroes, file metadata can indicate the
extent of such a run and the filesystem hides the distinction from user
applications.
II. Problem Description
When a file containing holes is mapped using mmap(2), mapped regions
of the file may be ignored by lseek(2) when SEEK_HOLE or SEEK_DATA are
passed as the "whence" parameter.
III. Impact
The bug may cause application misbehavior; the precise effects depend
on the nature of the application triggering the bug.
IV. Workaround
No workaround is available, but systems not using ZFS are not affected.
V. Solution
Upgrade your system to a supported FreeBSD stable or release / security
branch (releng) dated after the correction date and reboot.
Perform one of the following:
1) To update your system via a binary patch:
Systems running a RELEASE version of FreeBSD on the amd64, i386, or
(on FreeBSD 13 and later) arm64 platforms can be updated via the
freebsd-update(8) utility:
# freebsd-update fetch
# freebsd-update install
# shutdown -r +10min "Rebooting for an errata update"
2) To update your system via a source code patch:
The following patches have been verified to apply to the applicable
FreeBSD release branches.
a) Download the relevant patch from the location below, and verify the
detached PGP signature using your PGP utility.
# fetch https://security.FreeBSD.org/patches/EN-22:11/zfs.patch
# fetch https://security.FreeBSD.org/patches/EN-22:11/zfs.patch.asc
# gpg --verify zfs.patch.asc
b) Apply the patch. Execute the following commands as root:
# cd /usr/src
# patch < /path/to/patch
c) Recompile your kernel as described in
and reboot the
system.
VI. Correction details
This issue is corrected by the corresponding Git commit hash or Subversion
revision number in the following stable and release branches:

FreeBSD-SA-22:02.wifi Security Advisory
The FreeBSD Project
Topic: Multiple WiFi issues
Category: core
Module: net80211
Announced: 2022-03-15
Affects: FreeBSD 12.x and FreeBSD 13.0
Corrected: 2021-11-19 00:01:25 UTC (stable/13, 13.0-STABLE)
2022-03-15 17:45:36 UTC (releng/13.0, 13.0-RELEASE-p8)
2022-02-15 16:05:49 UTC (stable/12, 12.3-STABLE)
2022-03-15 18:18:08 UTC (releng/12.3, 12.3-RELEASE-p3)
2022-03-15 18:17:30 UTC (releng/12.2, 12.2-RELEASE-p14)
CVE Name: CVE-2020-26147, CVE-2020-24588, CVE-2020-26144
Note: This issue is already fixed in FreeBSD 13.1-BETA1.
For general information regarding FreeBSD Security Advisories,
including descriptions of the fields above, security branches, and the
following sections, please visit .
I. Background
FreeBSD's net80211 kernel subsystem provides infrastructure and drivers
for IEEE 802.11 wireless (Wi-Fi) communications.
II. Problem Description
The paper "Fragment and Forge: Breaking Wi-Fi Through Frame Aggregation and
Fragmentation" reported a number of security vulnerabilities in 802.11
-specificaiton related to frame aggregation and fragmentation.
+specification related to frame aggregation and fragmentation.
Additionally, FreeBSD 12.x missed length validation of SSIDs and Information
Elements (IEs).
III. Impact
As reported on the FragAttacks website, the "design flaws are hard to abuse
because doing so requires user interaction or is only possible when using
uncommon network settings." Under suitable conditions an attacker may be
able to extract sensitive data or inject data.
IV. Workaround
No workaround is available, but the ability to extract or inject data is
mitigated by the use of application (e.g. HTTPS) or transport (e.g. TLS,
IPSEC) layer encryption.
V. Solution
Upgrade your vulnerable system to a supported FreeBSD stable or
release / security branch (releng) dated after the correction date,
and reboot.
Perform one of the following:

freebsd-update(8) utility:
# freebsd-update fetch
# freebsd-update install
# shutdown -r +10min "Rebooting for a security update"
2) To update your vulnerable system via a source code patch:
The following patches have been verified to apply to the applicable
FreeBSD release branches.
a) Download the relevant patch from the location below, and verify the
detached PGP signature using your PGP utility.
