Asaf Modelevsky discovered that the Intel® 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
kernel contained an out-of-bounds write vulnerability. A local attacker
could use this to cause a denial of service (system crash) or possibly
execute arbitrary code. (CVE-2022-1943)
Gerald Lee discovered that the NTFS 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 (system crash) or possibly expose sensitive information.
(CVE-2022-1973)
Duoming Zhou discovered that race conditions existed in the timer handling
implementation of the Linux kernel’s Rose X.25 protocol layer, resulting in
use-after-free vulnerabilities. A local attacker could use this to cause a
denial of service (system crash). (CVE-2022-2318)
It was discovered that the device-mapper verity (dm-verity) driver in the
Linux kernel did not properly verify targets being loaded into the device-
mapper table. A privileged attacker could use this to cause a denial of
service (system crash) or possibly execute arbitrary code. (CVE-2022-2503)
Roger Pau Monné discovered that the Xen virtual block driver in the Linux
kernel did not properly initialize memory pages to be used for shared
communication with the backend. A local attacker could use this to expose
sensitive information (guest kernel memory). (CVE-2022-26365)
Zheyu Ma discovered that the Intel iSMT SMBus host controller driver in the
Linux kernel contained an out-of-bounds write vulnerability. A local
attacker could use this to cause a denial of service (system crash).
(CVE-2022-2873)
Selim Enes Karaduman discovered that a race condition existed in the pipe
buffers implementation of the Linux kernel. A local attacker could use this
to cause a denial of service (system crash) or possibly escalate
privileges. (CVE-2022-2959)
Roger Pau Monné discovered that the Xen paravirtualization frontend in the
Linux kernel did not properly initialize memory pages to be used for shared
communication with the backend. A local attacker could use this to expose
sensitive information (guest kernel memory). (CVE-2022-33740)
It was discovered that the Xen paravirtualization frontend in the Linux
kernel incorrectly shared unrelated data when communicating with certain
backends. A local attacker could use this to cause a denial of service
(guest crash) or expose sensitive information (guest kernel memory).
(CVE-2022-33741, CVE-2022-33742)
Jan Beulich discovered that the Xen network device frontend driver in the
Linux kernel incorrectly handled socket buffers (skb) references when
communicating with certain backends. A local attacker could use this to
cause a denial of service (guest crash). (CVE-2022-33743)
Oleksandr Tyshchenko discovered that the Xen paravirtualization platform in
the Linux kernel on ARM platforms contained a race condition in certain
situations. An attacker in a guest VM could use this to cause a denial of
service in the host OS. (CVE-2022-33744)
It was discovered that the virtio RPMSG bus driver in the Linux kernel
contained a double-free vulnerability in certain error conditions. A local
attacker could possibly use this to cause a denial of service (system
crash). (CVE-2022-34494, CVE-2022-34495)
Domingo Dirutigliano and Nicola Guerrera discovered that the netfilter
subsystem in the Linux kernel did not properly handle rules that truncated
packets below the packet header size. When such rules are in place, a
remote attacker could possibly use this to cause a denial of service
(system crash). (CVE-2022-36946)
