Ubuntu Security Notice USN-5865-1

Ubuntu Security Notice 5865-1 - It was discovered that an out-of-bounds write vulnerability existed in the Video for Linux 2 implementation in the Linux kernel. A local attacker could use this to cause a denial of service or possibly execute arbitrary code. Pawan Kumar Gupta, Alyssa Milburn, Amit Peled, Shani Rehana, Nir Shildan and Ariel Sabba discovered that some Intel processors with Enhanced Indirect Branch Restricted Speculation did not properly handle RET instructions after a VM exits. A local attacker could potentially use this to expose sensitive information.

linux-azure-4.15 vulnerabilities

A security issue affects these releases of Ubuntu and its derivatives:

  • Ubuntu 18.04 LTS

Summary:

Several security issues were fixed in the Linux kernel.

Software Description:

  • linux-azure-4.15: Linux kernel for Microsoft Azure Cloud systems

Details:

It was discovered that an out-of-bounds write vulnerability existed in the
Video for Linux 2 (V4L2) implementation in the Linux kernel. A local
attacker could use this to cause a denial of service (system crash) or
possibly execute arbitrary code. (CVE-2022-20369)

Pawan Kumar Gupta, Alyssa Milburn, Amit Peled, Shani Rehana, Nir Shildan
and Ariel Sabba discovered that some Intel processors with Enhanced
Indirect Branch Restricted Speculation (eIBRS) did not properly handle RET
instructions after a VM exits. A local attacker could potentially use this
to expose sensitive information. (CVE-2022-26373)

David Leadbeater discovered that the netfilter IRC protocol tracking
implementation in the Linux Kernel incorrectly handled certain message
payloads in some situations. A remote attacker could possibly use this to
cause a denial of service or bypass firewall filtering. (CVE-2022-2663)

Johannes Wikner and Kaveh Razavi discovered that for some AMD x86-64
processors, the branch predictor could by mis-trained for return
instructions in certain circumstances. A local attacker could possibly use
this to expose sensitive information. (CVE-2022-29900)

Johannes Wikner and Kaveh Razavi discovered that for some Intel x86-64
processors, the Linux kernel’s protections against speculative branch
target injection attacks were insufficient in some circumstances. A local
attacker could possibly use this to expose sensitive information.
(CVE-2022-29901)

It was discovered that the NILFS2 file system implementation in the Linux
kernel did not properly deallocate memory in certain error conditions. An
attacker could use this to cause a denial of service (memory exhaustion).
(CVE-2022-3646)

Khalid Masum discovered that the NILFS2 file system implementation in the
Linux kernel did not properly handle certain error conditions, leading to a
use-after-free vulnerability. A local attacker could use this to cause a
denial of service or possibly execute arbitrary code. (CVE-2022-3649)

Hyunwoo Kim discovered that an integer overflow vulnerability existed in
the PXA3xx graphics driver in the Linux kernel. A local attacker could
possibly use this to cause a denial of service (system crash).
(CVE-2022-39842)

It was discovered that a race condition existed in the SMSC UFX USB driver
implementation in the Linux kernel, leading to a use-after-free
vulnerability. A physically proximate attacker could use this to cause a
denial of service (system crash) or possibly execute arbitrary code.
(CVE-2022-41849)

It was discovered that a race condition existed in the Roccat HID driver in
the Linux kernel, leading to a use-after-free vulnerability. A local
attacker could use this to cause a denial of service (system crash) or
possibly execute arbitrary code. (CVE-2022-41850)

It was discovered that the USB monitoring (usbmon) component in the Linux
kernel did not properly set permissions on memory mapped in to user space
processes. A local attacker could use this to cause a denial of service
(system crash) or possibly execute arbitrary code. (CVE-2022-43750)

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 18.04 LTS:
linux-image-4.15.0-1161-azure 4.15.0-1161.176
linux-image-azure-lts-18.04 4.15.0.1161.129

After a standard system update you need to reboot your computer to make
all the necessary changes.

ATTENTION: Due to an unavoidable ABI change the kernel updates have
been given a new version number, which requires you to recompile and
reinstall all third party kernel modules you might have installed.
Unless you manually uninstalled the standard kernel metapackages
(e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual,
linux-powerpc), a standard system upgrade will automatically perform
this as well.

Ubuntu Security Notice USN-5683-1

Ubuntu Security Notice 5683-1 - It was discovered that the framebuffer driver on the Linux kernel did not verify size limits when changing font or screen size, leading to an out-of- bounds write. A local attacker could use this to cause a denial of service or possibly execute arbitrary code. Selim Enes Karaduman discovered that a race condition existed in the General notification queue implementation of the Linux kernel, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service or possibly execute arbitrary code.

CVE-2022-41686: en/security-disclosure/2022/2022-10.md · OpenHarmony/security - Gitee.com

OpenHarmony-v3.1.2 and prior versions, 3.0.6 and prior versions have an Out-of-bound memory read and write vulnerability in /dev/mmz_userdev device driver. The impact depends on the privileges of the attacker. The unprivileged process run on the device could read out-of-bound memory leading sensitive to information disclosure. The processes with system user UID run on the device would be able to write out-of-bound memory which could lead to unspecified memory corruption.

CVE-2022-41850: [PATCH v2] HID: roccat: Fix Use-After-Free in roccat_read

roccat_report_event in drivers/hid/hid-roccat.c in the Linux kernel through 5.19.12 has a race condition and resultant use-after-free in certain situations where a report is received while copying a report->value is in progress.

CVE-2022-41849: [PATCH v3] video: fbdev: smscufx: Fix use-after-free in ufx_ops_open()

drivers/video/fbdev/smscufx.c in the Linux kernel through 5.19.12 has a race condition and resultant use-after-free if a physically proximate attacker removes a USB device while calling open(), aka a race condition between ufx_ops_open and ufx_usb_disconnect.

CVE-2022-39842

An issue was discovered in the Linux kernel before 5.19. In pxa3xx_gcu_write in drivers/video/fbdev/pxa3xx-gcu.c, the count parameter has a type conflict of size_t versus int, causing an integer overflow and bypassing the size check. After that, because it is used as the third argument to copy_from_user(), a heap overflow may occur.

CVE-2022-2663: security - CVE-2022-2663: Linux netfilter: nf_conntrack_irc message handling

An issue was found in the Linux kernel in nf_conntrack_irc where the message handling can be confused and incorrectly matches the message. A firewall may be able to be bypassed when users are using unencrypted IRC with nf_conntrack_irc configured.

Ubuntu Security Notice USN-5564-1
