Several security issues were fixed in the Linux kernel.
Releases
Packages
- linux-nvidia-tegra-igx - Linux kernel for NVIDIA Tegra IGX systems
Details
Siebe Devroe, Héloïse Gollier, and Mathy Vanhoef discovered that the WiFi
implementation in the Linux kernel did not properly handle aggregated
frames in mesh networks, due to an incorrect fix for CVE-2020-24588. A
physically proximate attacker could use this issue to inject packets.
(CVE-2025-27558)
Several security issues were discovered in the Linux kernel.
An attacker could possibly use these to compromise the system.
This update corrects flaws in the following subsystems:
- x86 architecture;
- InfiniBand drivers;
- Network drivers;
- NVME drivers;
- Ext4 file system;
- SMB network file system;
- IPv4 networking;
- Network traffic control;
- TCP network protocol;
- Locking primitives;
- IPv6 networking;
- Multipath TCP;
- Netfilter;
- SCTP protocol;
- SMC...

Update instructions
After a standard system update you need to reboot your computer to make all the necessary changes.
Learn more about how to get the fixes.The problem can be corrected by updating your system to the following package versions:
Reduce your security exposure
Ubuntu Pro provides ten-year security coverage to 25,000+ packages in Main and Universe repositories, and it is free for up to five machines.
