linux-gcp vulnerabilities
\n==========================================================================<\/p>\n
A security issue affects these releases of Ubuntu and its derivatives:<\/p>\n
– Ubuntu 16.04 ESM<\/p>\n
Summary:<\/p>\n
Several security issues were fixed in the Linux kernel.<\/p>\n
Software Description:
\n– linux-gcp: Linux kernel for Google Cloud Platform (GCP) systems<\/p>\n
Details:<\/p>\n
It was discovered that the Upper Level Protocol (ULP) subsystem in the
\nLinux kernel did not properly handle sockets entering the LISTEN state in
\ncertain protocols, leading to a use-after-free vulnerability. A local
\nattacker could use this to cause a denial of service (system crash) or
\npossibly execute arbitrary code. (CVE-2023-0461)<\/p>\n
It was discovered that an out-of-bounds write vulnerability existed in the
\nVideo for Linux 2 (V4L2) implementation in the Linux kernel. A local
\nattacker could use this to cause a denial of service (system crash) or
\npossibly execute arbitrary code. (CVE-2022-20369)<\/p>\n
Pawan Kumar Gupta, Alyssa Milburn, Amit Peled, Shani Rehana, Nir Shildan
\nand Ariel Sabba discovered that some Intel processors with Enhanced
\nIndirect Branch Restricted Speculation (eIBRS) did not properly handle RET
\ninstructions after a VM exits. A local attacker could potentially use this
\nto expose sensitive information. (CVE-2022-26373)<\/p>\n
David Leadbeater discovered that the netfilter IRC protocol tracking
\nimplementation in the Linux Kernel incorrectly handled certain message
\npayloads in some situations. A remote attacker could possibly use this to
\ncause a denial of service or bypass firewall filtering. (CVE-2022-2663)<\/p>\n
Johannes Wikner and Kaveh Razavi discovered that for some AMD x86-64
\nprocessors, the branch predictor could by mis-trained for return
\ninstructions in certain circumstances. A local attacker could possibly use
\nthis to expose sensitive information. (CVE-2022-29900)<\/p>\n
Johannes Wikner and Kaveh Razavi discovered that for some Intel x86-64
\nprocessors, the Linux kernel’s protections against speculative branch
\ntarget injection attacks were insufficient in some circumstances. A local
\nattacker could possibly use this to expose sensitive information.
\n(CVE-2022-29901)<\/p>\n
It was discovered that a race condition existed in the Kernel Connection
\nMultiplexor (KCM) socket implementation in the Linux kernel when releasing
\nsockets in certain situations. A local attacker could use this to cause a
\ndenial of service (system crash). (CVE-2022-3521)<\/p>\n
It was discovered that the Netronome Ethernet driver in the Linux kernel
\ncontained a use-after-free vulnerability. A local attacker could use this
\nto cause a denial of service (system crash) or possibly execute arbitrary
\ncode. (CVE-2022-3545)<\/p>\n
It was discovered that the Broadcom FullMAC USB WiFi driver in the Linux
\nkernel did not properly perform bounds checking in some situations. A
\nphysically proximate attacker could use this to craft a malicious USB
\ndevice that when inserted, could cause a denial of service (system crash)
\nor possibly execute arbitrary code. (CVE-2022-3628)<\/p>\n
It was discovered that a use-after-free vulnerability existed in the
\nBluetooth stack in the Linux kernel. A local attacker could use this to
\ncause a denial of service (system crash) or possibly execute arbitrary
\ncode. (CVE-2022-3640)<\/p>\n
It was discovered that the NILFS2 file system implementation in the Linux
\nkernel did not properly deallocate memory in certain error conditions. An
\nattacker could use this to cause a denial of service (memory exhaustion).
\n(CVE-2022-3646)<\/p>\n
Khalid Masum discovered that the NILFS2 file system implementation in the
\nLinux kernel did not properly handle certain error conditions, leading to a
\nuse-after-free vulnerability. A local attacker could use this to cause a
\ndenial of service or possibly execute arbitrary code. (CVE-2022-3649)<\/p>\n
Hyunwoo Kim discovered that an integer overflow vulnerability existed in
\nthe PXA3xx graphics driver in the Linux kernel. A local attacker could
\npossibly use this to cause a denial of service (system crash).
\n(CVE-2022-39842)<\/p>\n
It was discovered that a race condition existed in the SMSC UFX USB driver
\nimplementation in the Linux kernel, leading to a use-after-free
\nvulnerability. A physically proximate attacker could use this to cause a
\ndenial of service (system crash) or possibly execute arbitrary code.
\n(CVE-2022-41849)<\/p>\n
It was discovered that a race condition existed in the Roccat HID driver in
\nthe Linux kernel, leading to a use-after-free vulnerability. A local
\nattacker could use this to cause a denial of service (system crash) or
\npossibly execute arbitrary code. (CVE-2022-41850)<\/p>\n
It was discovered that a race condition existed in the Xen network backend
\ndriver in the Linux kernel when handling dropped packets in certain
\ncircumstances. An attacker could use this to cause a denial of service
\n(kernel deadlock). (CVE-2022-42328, CVE-2022-42329)<\/p>\n
Tam\u00e1s Koczka discovered that the Bluetooth L2CAP implementation in the
\nLinux kernel did not properly initialize memory in some situations. A
\nphysically proximate attacker could possibly use this to expose sensitive
\ninformation (kernel memory). (CVE-2022-42895)<\/p>\n
It was discovered that the USB monitoring (usbmon) component in the Linux
\nkernel did not properly set permissions on memory mapped in to user space
\nprocesses. A local attacker could use this to cause a denial of service
\n(system crash) or possibly execute arbitrary code. (CVE-2022-43750)<\/p>\n
It was discovered that the NTFS file system implementation in the Linux
\nkernel did not properly validate attributes in certain situations, leading
\nto an out-of-bounds read vulnerability. A local attacker could possibly use
\nthis to expose sensitive information (kernel memory). (CVE-2023-26607)<\/p>\n
Update instructions:<\/p>\n
The problem can be corrected by updating your system to the following
\npackage versions:<\/p>\n
Ubuntu 16.04 ESM:
\nlinux-image-4.15.0-1146-gcp 4.15.0-1146.162~16.04.1
\nlinux-image-gcp 4.15.0.1146.136
\nlinux-image-gke 4.15.0.1146.136<\/p>\n
After a standard system update you need to reboot your computer to make
\nall the necessary changes.<\/p>\n
ATTENTION: Due to an unavoidable ABI change the kernel updates have
\nbeen given a new version number, which requires you to recompile and
\nreinstall all third party kernel modules you might have installed.
\nUnless you manually uninstalled the standard kernel metapackages
\n(e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual,
\nlinux-powerpc), a standard system upgrade will automatically perform
\nthis as well.<\/p>\n
