CVE-2023-46838: NULL Pointer Dereference

Transmit requests in Xen's virtual network protocol can consist of multiple parts. While not really useful, except for the initial part any of them may be of zero length, i.e. carry no data at all. Besides a certain initial portion of the to be transferred data, these parts are directly translate...

USN-6548-5 linux-iot vulnerabilities

It was discovered that Spectre-BHB mitigations were missing for Ampere processors. A local attacker could potentially use this to expose sensitive information. CVE-2023-3006 It was discovered that the USB subsystem in the Linux kernel contained a race condition while handling device descriptors i...

UBUNTU-CVE-2023-6270

A flaw was found in the ATA over Ethernet AoE driver in the Linux kernel. The aoecmdcfgpkts function improperly updates the refcnt on struct netdevice, and a use-after-free can be triggered by racing between the free on the struct and the access through the skbtxq global queue. This could lead to...

Linux Kernel Security Vulnerability

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, which stems from a contention issue with GC deletion of SKBs with unixstreamreadgeneric, leading to reuse after release...
