CVE-2022-2318

Affected: Kernel

There are use-after-free vulnerabilities caused by timer handler in net/rose/rose_timer.c of linux that allow attackers to crash linux kernel without any privileges.

USN-5623-1 — linux-hwe-5.15, linux-lowlatency-hwe-5.15 vulnerabilities

Affected: Ubuntu:20.04:LTS: linux-hwe-5.15, Ubuntu:20.04:LTS: linux-lowlatency-hwe-5.15

Asaf Modelevsky discovered that the Intel(R) 10GbE PCI Express (ixgbe) Ethernet driver for the Linux kernel performed insufficient control flow management. A local attacker could possibly use this to cause a denial of service. (CVE-2021-33061)

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 (system crash) or possibly execute arbitrary code. (CVE-2021-33655)

Moshe Kol, Amit Klein and Yossi Gilad discovered that the IP implementation in the Linux kernel did not provide sufficient randomization when calculating port offsets. An attacker could possibly use this to expose sensitive information. (CVE-2022-1012, CVE-2022-32296)

Norbert Slusarek discovered that a race condition existed in the perf subsystem in the Linux kernel, resulting in a use-after-free vulnerability. A privileged local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2022-1729)

Qiuhao Li, Gaoning Pan, and Yongkang Jia discovered that the KVM hypervisor implementation in the Linux kernel did not properly handle an illegal instruction in a guest, resulting in a null pointer dereference. An attacker in a guest VM could use this to cause a denial of service (system crash) in the host OS. (CVE-2022-1852)

It was discovered that the UDF file system implementation in the Linux kern…
