Kernel news

Ubuntu has issued a security notice for multiple vulnerabilities discovered in the Linux kernel. The flaws affect key subsystems, including network drivers and the BTRFS file system. An attacker could potentially exploit these issues to compromise a system, making immediate updates essential for all affected users.

Multiple security vulnerabilities have been discovered in the Linux kernel, affecting its cryptographic API and packet sockets. A significant flaw, dubbed "Copy Fail," could allow a local attacker to escalate privileges or even escape a container, potentially leading to a full system compromise. An update has been released.

Ubuntu has released a security update for the Linux kernel used in NVIDIA Tegra systems. The update addresses several vulnerabilities in network drivers, NVME drivers, and Netfilter that could allow an attacker to compromise an affected system. Applying the patch is recommended for all users.

A new Linux kernel vulnerability named "Dirty Frag" has been found in versions 4.10 and later. It allows for local privilege escalation by combining two previously known flaws. The issue is in the IP packet fragmentation system and was publicly disclosed on May 7, 2026.

A nine-year-old vulnerability (CVE-2026-46333) has been found in the Linux kernel. The flaw, caused by improper privilege management, allows a local user without special permissions to access sensitive files and execute commands with root privileges on default installations of several major Linux distributions.

Ubuntu has issued a security notice detailing several vulnerabilities discovered in the Linux kernel. The flaws affect network drivers, NVME drivers, and IPv4 networking subsystems. An attacker could potentially exploit these issues to compromise a system, making the provided security update essential for all users.

Ubuntu has released security updates for the Linux kernel on Xilinx ZynqMP systems. These patches address multiple vulnerabilities, including critical flaws in the OverlayFS implementation that could allow a local attacker to gain elevated privileges and compromise the security of affected devices.

Ubuntu has patched several Linux kernel vulnerabilities, including two in its OverlayFS file system. These flaws could allow a local attacker to bypass permission checks and gain elevated privileges, potentially leading to unauthorized system control. Users should update their systems immediately to mitigate the risk.

Ubuntu has patched several vulnerabilities in the Linux kernel. One major flaw, known as 'Copy Fail,' could allow a local attacker to escalate privileges or escape a container. Other issues were found in subsystems like networking, cryptography, and I/O, which could also lead to system compromise.

Ubuntu has released a security update for the Linux kernel, fixing several vulnerabilities. The most critical flaw, known as Copy Fail, could allow a local attacker to escalate privileges or escape from a container. The patch also addresses issues in various other kernel subsystems to prevent system compromise.

A proof-of-concept exploit is now public for a high-severity Linux kernel vulnerability dubbed 'DirtyDecrypt.' The flaw allows a local user to gain root privileges on systems with the `rxgk` module enabled. Major distributions are affected, and patches are available. Teams should update their systems immediately.

Ubuntu has patched several vulnerabilities in the Linux kernel. A key flaw, dubbed "Copy Fail," could allow a local attacker to escalate privileges or escape a container. Other issues affect the cryptographic API, packet sockets, and TLS protocol, potentially leading to system compromise.

Ubuntu has issued a security notice for multiple Linux kernel vulnerabilities. The update patches several flaws, including a critical issue in a cryptographic module dubbed "Copy Fail." This specific vulnerability could allow a local attacker to gain elevated privileges or potentially escape from a container environment.
