USN-5120-1: Linux kernel (Azure) vulnerabilities

It was discovered that the f2fs file system in the Linux kernel did not properly validate metadata in some situations. An attacker could use this to construct a malicious f2fs image that, when mounted and operated on, could cause a denial of service system crash or possibly execute arbitrary code...

USN-5115-1: Linux kernel (OEM) vulnerabilities

It was discovered that a race condition existed in the Atheros Ath9k WiFi driver in the Linux kernel. An attacker could possibly use this to expose sensitive information WiFi network traffic. CVE-2020-3702 Ofek Kirzner, Adam Morrison, Benedict Schlueter, and Piotr Krysiuk discovered that the BPF...

USN-5092-3: Linux kernel (Azure) regression

USN-5092-2 fixed vulnerabilities in Linux 5.11-based kernels. Unfortunately, for Linux kernels intended for use within Microsoft Azure environments, that update introduced a regression that could cause the kernel to fail to boot in large Azure instance types. This update fixes the problem. We...

The vulnerability in the `drivers/net/ethernet/xilinx/xilinx_emaclite.c` component of the Linux operating system allows a hacker to bypass the ASLR protection mechanism.

The vulnerability in the drivers/net/ethernet/xilinx/xilinxemaclite.c component of the Linux kernel is related to the use of uninitialized memory. Exploiting this vulnerability could allow an attacker to bypass the ASLR protection mechanism...

Amazon Linux AMI : kernel (ALAS-2021-1539)

The version of kernel installed on the remote host is prior to 4.14.248-129.473. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS-2021-1539 advisory. A flaw was found in the Linux kernel. When reusing a socket with an attached dccpshctxccid as a listener, the socke...

USN-5094-2: Linux kernel (Raspberry Pi) vulnerabilities

It was discovered that the KVM hypervisor implementation in the Linux kernel did not properly perform reference counting in some situations, leading to a use-after-free vulnerability. An attacker who could start and control a VM could possibly use this to expose sensitive information or execute...

Bypass Of Protection Mechanism

linux is vulnerable to privilege escalation. drivers/net/ethernet/xilinx/xilinxemaclite.c in the Linux kernel makes it easier for attackers to defeat an ASLR protection mechanism because it prints a kernel pointer i.e., the real IOMEM pointer...

USN-5070-1: Linux kernel vulnerabilities

Maxim Levitsky and Paolo Bonzini discovered that the KVM hypervisor implementation for AMD processors in the Linux kernel allowed a guest VM to disable restrictions on VMLOAD/VMSAVE in a nested guest. An attacker in a guest VM could use this to read or write portions of the host's physical memory...

The vulnerability in the driver/net/ethernet/xilinx/ll_temac_main.c component of the Linux operating system allows a hacker to cause a service failure.

The vulnerability in the drivers/net/ethernet/xilinx/lltemacmain.c component of the Linux operating system is related to buffer overflow vulnerabilities. Exploiting this vulnerability can allow an attacker to cause a service failure remotely...

Updated kernel-linus packages fix security vulnerabilities

This kernel-linus update is based on upstream 5.10.60 and fixes at least the following security issues: A missing validation of the "intctl" VMCB field allows a malicious L1 guest to enable AVIC support Advanced Virtual Interrupt Controller for the L2 guest. The L2 guest is able to write to a...
