NVIDIA 580.105.08, a new point release for the latest production branch driver for Linux, was released yesterday.
This is the 5th release in the NVIDIA 580 series. It introduced a new environment variable and fixed various bugs.
In the passt 4 NVIDIA 580 releases, it added fifo-v1 protocol support for Vulkan apps running on Wayland session, reducing visual inconsistencies and potential stuttering.
It as well enabled RMIntrLockingMode feature by default, which can help reduce stutter especially when using virtual reality (VR), and, added Smooth Motion frame generation support for GeForce RTX 40 Series GPUs.

In the new 580.105.08 driver, it added new CUDA_DISABLE_PERF_BOOST environment variable, allowing to disable boosting the GPU to a higher power state when running CUDA applications.
This is useful for saving power and prevent overheating, when your GPU is powerful enough handling the job when running at base clock speed.
To enable this feature, you may set it per app basis:
Loginexport CUDA_DISABLE_PERF_BOOST=1 in terminal, and start apps from that terminal window.env CUDA_DISABLE_PERF_BOOST=1 /path/to/executable EXEC value in your app’s desktop entry (.desktop file).Or, write export CUDA_DISABLE_PERF_BOOST=1 to .profiles or .bashrc file so it works for all CUDA applications.
Besides that, the new driver also fixed various bugs. They include crashes for Metro Exodus EE and Rage2 video games, as well as:
And, here are more features in NVIDIA 580 driver series:
OutputBitsPerComponent” MetaMode attribute to control the number of bits per color component transmitted via a display connector.For more details, see the releases for NVIDIA 580.65.06, 580.76.05, 580.82.07, 580.95.05, and 580.105.08.
Ubuntu has made NVIDIA 580 driver packages into system repository (restricted) for current Ubuntu 22.04, 24.04, 25.04 and 25.10.
So far, it’s NVIDIA 580.95.05. While, the latest 580.105.08 as usual will be available in next few weeks if everything goes well.
If you can’t wait, then try adding the popular “Graphics Drivers” team PPA which usually updates the driver packages timely.
After that, use either ubuntu-drivers install nvidia:580 command, or “Additional Drivers” utility to install the driver package.

The Linux kernel, foundational for servers, desktops, embedded systems, and cloud infrastructure, has been under heightened scrutiny. Several vulnerabilities have been exploited in real-world attacks, targeting critical subsystems and isolation layers. In this article, we’ll walk through major examples, explain their significance, and offer actionable guidance for defenders.
One of the most alarming flaws this year involves a use-after-free vulnerability in the Linux kernel’s vsock implementation (Virtual Socket), which enables communication between virtual machines and their hosts.
How the exploit works: A malicious actor inside a VM (or other privileged context) manipulates reference counters when a vsock transport is reassigned. The code ends up freeing a socket object while it’s still in use, enabling memory corruption and potentially root-level access.
Why it matters: Since vsock is used for VM-to-host and inter-VM communication, this flaw breaks a key isolation barrier. In multi-tenant cloud environments or container hosts that expose vsock endpoints, the impact can be severe.
Mitigation: Kernel maintainers have released patches. If your systems run hosts, hypervisors, or other environments where vsock is present, make sure the kernel is updated and virtualization subsystems are patched.
Another high-impact vulnerability involves the UNIX domain socket interface and the MSG_OOB flag. The bug was publicly detailed in August 2025 and is already in active discussion.
Attack scenario:
A process running inside a sandbox (for example a browser renderer) can exploit MSG_OOB operations on a UNIX domain socket to trigger a use-after-free or out-of-bounds read/write. That allows leaking kernel pointers or memory and then chaining to full kernel privilege escalation.
Why it matters: This vulnerability is especially dangerous because it bridges from a low-privilege sandboxed process to kernel-level compromise. Many systems assume sandboxed code is safe; this attack undermines that assumption.
Mitigation:
Distributions and vendors (like browser teams) have disabled or restricted MSG_OOB usage for sandboxed contexts. Kernel patches are available. Systems that run browser sandboxes or other sandboxed processes need to apply these updates immediately.
In September 2025, the U.S. Cybersecurity & Infrastructure Security Agency (CISA) added this vulnerability to its Known Exploited Vulnerabilities (KEV) catalog.
Extracting tables from PDF files in Python is not always a straightforward process unless you have a specific library to do that. For PDF data extraction, using Camelot is one of the go-to tools. The best part is that it is not very difficult to install, especially if you already have Python, as its package […]

KeePass Password Safe released new 2.60 version few days ago. Here are the new features and PPA update for Ubuntu users.
The new release of this free open-source password manager application added support importing .csv passwords exported from Mozilla Firefox web browser.
KeePass 2.60 support importing Firefox Password CSV
It as well improved Bitwarden JSON support. Now, if the value of a totp field consists only of Base32 characters, it is now treated as a shared secret for time-based one-time password generation.
The release also improved the app user interface. The quick search box now search for group paths, while a toggle option is available in Tools -> Options -> Interface (1) to turn on/off the feature.
The drop-down box for quick search box, which can be opened by Alt + Down now supports keyboard navigation and selection. However, due to bug, the auto-completion of the quick search box is disabled.
For users who have many groups, the release now supports displaying ‘Group Path’ and ‘Group Name’ list columns in the main entry. Though, the feature is not enabled by default. User may enable them by going to ‘View’ → ‘Configure Columns’.
KeePass 2.60 also improved the app user experience for keyboard users. It now supports pressing Ctrl+A to select all items in the list views, and Delete to delete selected items in list views that have a corresponding ‘Delete’ button.
And, for those who use Ctrl+Alt+A for the global auto-type hot key, while French Standard AZERTY keyboard layout is active, it shows a warning dialog telling the conflict along with a ‘More information’ link.
Other changes in the release include:
The official installer and portable zip archive for Windows are available to download in its website along with KeePass 1.x and source tarball.
For choice, you may go directly to this sourceforge page download page.
For Ubuntu user, there’s no official package for the new release so far. Besides building from source, I’ve uploaded the package into this unofficial PPA for Ubuntu 20.04, Ubuntu 22.04, Ubuntu 24.04, 25.04 and 25.10.
You may press Ctrl+Alt+T on keyboard to open terminal, then run the commands below one by one to add PPA & install the password manager:
sudo add-apt-repository ppa:ubuntuhandbook1/keepass2 sudo apt update sudo apt install keepass2
To uninstall the PPA package, run command:
sudo apt remove keepass2
And, remove the PPA either by running the command below in terminal:
sudo add-apt-repository --remove ppa:ubuntuhandbook1/keepass2
Or, launch “Software & Updates” and remove the source line under Other Software tab.
