After a standard system update you need to reboot your computer to make
all the necessary changes.

ATTENTION: Due to an unavoidable ABI change the kernel updates have
been given a new version number, which requires you to recompile and
reinstall all third party kernel modules you might have installed.
Unless you manually uninstalled the standard kernel metapackages
(e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual,
linux-powerpc), a standard system upgrade will automatically perform
this as well.

linux-raspi vulnerabilities
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 22.04 LTS

Summary:

Several security issues were fixed in the Linux kernel.

Software Description:
- linux-raspi: Linux kernel for Raspberry Pi systems

Details:

Qualys discovered that several vulnerabilities existed in the AppArmor
Linux kernel Security Module (LSM). An unprivileged local attacker could
use these issues to load, replace, and remove arbitrary AppArmor profiles
causing denial of service, exposure of sensitive information (kernel
memory), local privilege escalation, or possibly escape a container.

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 22.04 LTS
linux-image-5.15.0-1097-raspi 5.15.0-1097.100
linux-image-raspi 5.15.0.1097.95
linux-image-raspi-5.15 5.15.0.1097.95
linux-image-raspi-nolpae 5.15.0.1097.95

After a standard system update you need to reboot your computer to make
all the necessary changes.

ATTENTION: Due to an unavoidable ABI change the kernel updates have
been given a new version number, which requires you to recompile and
reinstall all third party kernel modules you might have installed.
Unless you manually uninstalled the standard kernel metapackages
(e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual,
linux-powerpc), a standard system upgrade will automatically perform
this as well.

Ubuntu Security Notice USN-8095-5
April 01, 2026

linux-raspi, linux-raspi-realtime vulnerabilities
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 24.04 LTS

Summary:

Several security issues were fixed in the Linux kernel.

Software Description:
- linux-raspi: Linux kernel for Raspberry Pi systems
- linux-raspi-realtime: Linux kernel for Raspberry Pi Real-time systems

Details:

Qualys discovered that several vulnerabilities existed in the AppArmor
Linux kernel Security Module (LSM). An unprivileged local attacker could
use these issues to load, replace, and remove arbitrary AppArmor profiles
causing denial of service, exposure of sensitive information (kernel
memory), local privilege escalation, or possibly escape a container.
(LP: #2143853)

Several security issues were discovered in the Linux kernel.
An attacker could possibly use these to compromise the system.

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 24.04 LTS
linux-image-6.8.0-1050-raspi 6.8.0-1050.54
linux-image-6.8.0-2040-raspi-realtime 6.8.0-2040.41
Available with Ubuntu Pro
linux-image-raspi 6.8.0-1050.54
linux-image-raspi-6.8 6.8.0-1050.54
linux-image-raspi-realtime 6.8.0-2040.41
Available with Ubuntu Pro
linux-image-raspi-realtime-6.8 6.8.0-2040.41
Available with Ubuntu Pro

After a standard system update you need to reboot your computer to make
all the necessary changes.

ATTENTION: Due to an unavoidable ABI change the kernel updates have
been given a new version number, which requires you to recompile and
reinstall all third party kernel modules you might have installed.
Unless you manually uninstalled the standard kernel metapackages
(e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual,
linux-powerpc), a standard system upgrade will automatically perform
this as well.

Ubuntu Security Notice USN-8094-5
April 01, 2026

linux-raspi vulnerabilities
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 25.10

Summary:

Several security issues were fixed in the Linux kernel.

Software Description:
- linux-raspi: Linux kernel for Raspberry Pi systems

Details:

Qualys discovered that several vulnerabilities existed in the AppArmor
Linux kernel Security Module (LSM). An unprivileged local attacker could
use these issues to load, replace, and remove arbitrary AppArmor profiles
causing denial of service, exposure of sensitive information (kernel
memory), local privilege escalation, or possibly escape a container.
(LP: #2143853)

It was discovered that some AMD Zen 5 processors supporting RDSEED
instruction did not properly handle entropy, potentially resulting in the
consumption of insufficiently random values. A local attacker could
possibly use this issue to influence the values returned by the RDSEED
instruction causing loss of confidentiality and integrity. (CVE-2025-62626)

Several security issues were discovered in the Linux kernel.
An attacker could possibly use these to compromise the system.

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 25.10
linux-image-6.17.0-1010-raspi 6.17.0-1010.10
linux-image-raspi 6.17.0-1010.10
linux-image-raspi-6.17 6.17.0-1010.10

After a standard system update you need to reboot your computer to make
all the necessary changes.

ATTENTION: Due to an unavoidable ABI change the kernel updates have
been given a new version number, which requires you to recompile and
reinstall all third party kernel modules you might have installed.
Unless you manually uninstalled the standard kernel metapackages
(e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual,
linux-powerpc), a standard system upgrade will automatically perform
this as well.

[USN-8138-1] tar-rs vulnerability

==========================================================================
Ubuntu Security Notice USN-8138-1
April 01, 2026

rust-tar vulnerability
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 25.10
- Ubuntu 24.04 LTS
- Ubuntu 22.04 LTS

Summary:

tar-rs could be made to modify permissions on arbitrary directories.

Software Description:
- rust-tar: A tar archive reading/writing library for Rust

Details:

It was discovered that tar-rs incorrectly handled symlinks when unpacking a
tar archive. If a user or automated system were tricked into processing a
specially crafted tar archive, a remote attacker could use this issue to
modify permissions of arbitrary directories outside the extraction root,
and possibly escalate privileges.

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 25.10
librust-tar-dev 0.4.43-4ubuntu0.1

Ubuntu 24.04 LTS
librust-tar-dev 0.4.40-1ubuntu0.1

Ubuntu 22.04 LTS
librust-tar+default-dev 0.4.37-3ubuntu0.1
librust-tar-dev 0.4.37-3ubuntu0.1

In general, a standard system update will make all the necessary changes.

[USN-8139-1] cargo-c vulnerability

==========================================================================
Ubuntu Security Notice USN-8139-1
April 01, 2026

rust-cargo-c vulnerability
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 25.10

Summary:

cargo-c could be made to modify permissions on arbitrary directories.

Software Description:
- rust-cargo-c: Helper program to build and install c-like libraries

Details:

It was discovered that tar-rs embedded in cargo-c incorrectly handled
symlinks when unpacking a tar archive. If a user or automated system were
tricked into processing a specially crafted tar archive, a remote attacker
could use this issue to modify permissions of arbitrary directories outside
the extraction root, and possibly escalate privileges.

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 25.10
cargo-c 0.10.11-1ubuntu1.1
librust-cargo-c-dev 0.10.11-1ubuntu1.1

[announce] NYC*BUG Tonight: Michael W Lucas

Note: MWL will be remote, so the meeting will be streamed from
https://www.nycbug.org/streaming.html, and some local NYC people will be
watching at the Brass Monkey.

What's Changed Since The Last Time I Came this Way - a talk that was
supposed to be about OpenZFS, Michael W Lucas

2026-04-01 @ 18:45 local (22:45 UTC) - Backroom of Brass Monkey 55
Little West 12th St

Remote participation: Plans are to stream via NYC*BUG website. Q&A will
be via IRC on libera.chat channel #nycbug - please preface your
questions with '[Q]'.

Michael W Lucas and Allan Jude are busy working on a new OpenZFS book,
which means not only documenting everything that's changed in the last
12 years but discovering everything that they got wrong the first time.
The quest for accuracy has taken Lucas deep into mailing list archives,
Usenet, VAX installation manuals, the Kremlin's first Internet
connection, the United Nations' effort to merge the BSD projects, and
the ULTRIX and S51K filesystems, and left MWL more convinced than ever
that filesystems are nothing but a April Fools' prank. This hurriedly
conceived and hastily assembled talk will update you on new OpenZFS
features, but will also try to determine if it's a good prank–or not.


Michael W Lucas' name may ring a bell for some in the BSD community.
He's written several shelves of books. But for anyone who has seen him
speak in public during Ante COVID days, it was clear they are mere
transcriptions of his rambling presentations. For this NYC*BUG meeting,
he is unlikely to edit out any of his expected corny jokes we endure
during his conference presentations.

More likely, you know his name from his grotesque horror fiction. In the
same way his technical books are just transcriptions of his
presentations, his fictionaal horror is just a simple reflection of
someone who lives in a haunted house filled with (pet) rats in Detroit.

Nearest NYC Subway is the 14th Street/Eighth Avenue station L, A, C, E.

To get to the backroom, you must enter the front door, follow the long
bar on your left, and walk all the way to the back. At the rear of the
BrassMonkey, you will see an alcove for the 3 bathrooms our room is off
to your right.

Fedora 44 Final Freeze Is Now In Effect

Hi all,

Today, 2026-03-31, is an important day on the Fedora Linux 44 schedule [1], with significant cut-offs.

Today we have the Final Freeze [2] which starts at 14:00 UTC. This means that only packages fixing accepted blocker or freeze exception bugs [3][4][5] will be marked as 'stable' and included in the Final composes. Other builds will remain in updates-testing until the Final release is approved. At that point, the final freeze is lifted and packages can move to the 'updates' repository. Pending updates will be pushed before final release as zero day updates.

Regards,
Patrik Polakovic
