Linux Kernel Security Vulnerabilities

Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. A security vulnerability exists in the Linux kernel that stems from an nftables netlink notifier race condition to release an object, which could lead to reuse after release...

CVE-2022-49766: Undefined Security Weakness

In the Linux kernel, the following vulnerability has been resolved: netlink: Bounds-check struct nlmsgerr creation In preparation for FORTIFYSOURCE doing bounds-check on memcpy, switch from nlmsgput to nlmsgput, and explain the bounds check for dealing with the memcpy across a composite flexible...

Important: kernel

Issue Overview: A flaw was found in the Linux kernel's Layer 2 Tunneling Protocol L2TP. A missing lock when clearing skuserdata can lead to a race condition and NULL pointer dereference. A local user could use this flaw to potentially crash the system causing a denial of service. CVE-2022-4129 In...

SUSE CVE-2025-22111

In the Linux kernel, the following vulnerability has been resolved: net: Remove RTNL dance for SIOCBRADDIF and SIOCBRDELIF. SIOCBRDELIF is passed to devioctl first and later forwarded to brioctlcall, which causes unnecessary RTNL dance and the splat below 0 under RTNL pressure. Let's say Thread A...
