CVE-2026-80519

A flaw was found in the Linux kernel. Specifically, within the OpenVPN OVPN module's crypto completion callback mechanism, a timing issue exists. This vulnerability arises when peer references are released prematurely, before the associated cleanup operations are complete. An attacker could...

CVE-2026-74730

A flaw was found in the Linux kernel's Network File System NFS. This vulnerability involves improper memory handling where a critical data structure is released prematurely if a FREESTATEID operation is delayed. This can lead to memory corruption, potentially causing system instability or a denia...

CVE-2026-49743

Software installed and run as a non-privileged user may conduct improper GPU system calls to manipulate the lifetimes of synchronisation objects in the kernel, leading to read/write UAFs. During workload submission involving a fence exported by the GPU driver, the reference count of the underlyin...

Linux Kernel Memory Vulnerability (CNVD-2026-26372)

The Linux kernel is the core of the Linux operating system, responsible for managing system resources, process scheduling, file systems, and other functions. The Linux kernel has a memory corruption vulnerability. This vulnerability arises due to the btrfs module releasing dirty page IO trees...

CVE-2026-53248

A flaw was found in the Linux kernel's airoha network driver. This use-after-free vulnerability occurs when the airohametadatadstfree function frees memory prematurely, before all references to it are released. If a network packet still holds a pointer to the freed memory, a use-after-free...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: unittest: Fix for use-after-free in testdrvprobe The function testdrvprobe retrieves the devicenode from the PCI device, applies an overlay, and then immediately calls ofnodeputdn. This releases the reference held by the PCI core...

Squid: Squid: Denial of Service via crafted ICP traffic

A flaw was found in Squid. A remote attacker can exploit this vulnerability by sending specially crafted ICP Internet Cache Protocol traffic. This can lead to a Denial of Service DoS due to premature resource release and use-after-free vulnerabilities. This attack is possible in Squid deployments...
