\nUbuntu Security Notice USN-6247-1

linux-oem-5.17 vulnerabilities
\n==========================================================================<\/p>\n
A security issue affects these releases of Ubuntu and its derivatives:<\/p>\n
– Ubuntu 22.04 LTS<\/p>\n
Summary:<\/p>\n
Several security issues were fixed in the Linux kernel.<\/p>\n
Software Description:
\n– linux-oem-5.17: Linux kernel for OEM systems<\/p>\n
Details:<\/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
It was discovered that the IDT 77252 ATM PCI device driver in the Linux
\nkernel did not properly remove any pending timers during device exit,
\nresulting in a use-after-free vulnerability. A local attacker could
\npossibly use this to cause a denial of service (system crash) or execute
\narbitrary code. (CVE-2022-3635)<\/p>\n
It was discovered that the network queuing discipline implementation in the
\nLinux kernel contained a null pointer dereference in some situations. A
\nlocal attacker could use this to cause a denial of service (system crash).
\n(CVE-2022-47929)<\/p>\n
Lucas Leong discovered that the IPv6 SR implementation in the Linux kernel
\ndid not properly validate SEG6 configuration attributes, leading to an out-
\nof-bounds read vulnerability. A privileged attacker could use this to
\nexpose sensitive information (kernel memory). (CVE-2023-2860)<\/p>\n
Mingi Cho discovered that the netfilter subsystem in the Linux kernel did
\nnot properly validate the status of a nft chain while performing a lookup
\nby id, leading to a use-after-free vulnerability. An attacker could use
\nthis to cause a denial of service (system crash) or possibly execute
\narbitrary code. (CVE-2023-31248)<\/p>\n
Tanguy Dubroca discovered that the netfilter subsystem in the Linux kernel
\ndid not properly handle certain pointer data type, leading to an out-of-
\nbounds write vulnerability. A privileged attacker could use this to cause a
\ndenial of service (system crash) or possibly execute arbitrary code.
\n(CVE-2023-35001)<\/p>\n
Update instructions:<\/p>\n
The problem can be corrected by updating your system to the following
\npackage versions:<\/p>\n
Ubuntu 22.04 LTS:
\nlinux-image-5.17.0-1035-oem 5.17.0-1035.36
\nlinux-image-oem-22.04 5.17.0.1035.33
\nlinux-image-oem-22.04a 5.17.0.1035.33<\/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
