USN-5962-1: Linux kernel (Intel IoTG) vulnerabilities

USN-5962-1: Linux kernel (Intel IoTG) vulnerabilities

It was discovered that the Upper Level Protocol (ULP) subsystem in the
Linux kernel did not properly handle sockets entering the LISTEN state in
certain protocols, 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-2023-0461)

Davide Ornaghi discovered that the netfilter subsystem in the Linux kernel
did not properly handle VLAN headers in some situations. A local attacker
could use this to cause a denial of service (system crash) or possibly
execute arbitrary code. (CVE-2023-0179)

It was discovered that the NVMe driver in the Linux kernel did not properly
handle reset events in some situations. A local attacker could use this to
cause a denial of service (system crash). (CVE-2022-3169)

Maxim Levitsky discovered that the KVM nested virtualization (SVM)
implementation for AMD processors in the Linux kernel did not properly
handle nested shutdown execution. An attacker in a guest vm could use this
to cause a denial of service (host kernel crash) (CVE-2022-3344)

Gwangun Jung discovered a race condition in the IPv4 implementation in the
Linux kernel when deleting multipath routes, resulting in an out-of-bounds
read. An attacker could use this to cause a denial of service (system
crash) or possibly expose sensitive information (kernel memory).
(CVE-2022-3435)

It was discovered that a race condition existed in the Kernel Connection
Multiplexor (KCM) socket implementation in the Linux kernel when releasing
sockets in certain situations. A local attacker could use this to cause a
denial of service (system crash). (CVE-2022-3521)

It was discovered that the Netronome Ethernet driver in the Linux kernel
contained 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-2022-3545)

It was discovered that the Intel i915 graphics driver in the Linux kernel
did not perform a GPU TLB flush in some situations. A local attacker could
use this to cause a denial of service or possibly execute arbitrary code.
(CVE-2022-4139)

It was discovered that a race condition existed in the Xen network backend
driver in the Linux kernel when handling dropped packets in certain
circumstances. An attacker could use this to cause a denial of service
(kernel deadlock). (CVE-2022-42328, CVE-2022-42329)

It was discovered that the NFSD implementation in the Linux kernel
contained a use-after-free vulnerability. A remote attacker could possibly
use this to cause a denial of service (system crash) or execute arbitrary
code. (CVE-2022-4379)

It was discovered that a race condition existed in the x86 KVM subsystem
implementation in the Linux kernel when nested virtualization and the TDP
MMU are enabled. An attacker in a guest vm could use this to cause a denial
of service (host OS crash). (CVE-2022-45869)

It was discovered that the Atmel WILC1000 driver in the Linux kernel did
not properly validate the number of channels, leading to an out-of-bounds
write vulnerability. An attacker could use this to cause a denial of
service (system crash) or possibly execute arbitrary code. (CVE-2022-47518)

It was discovered that the Atmel WILC1000 driver in the Linux kernel did
not properly validate specific attributes, leading to an out-of-bounds
write vulnerability. An attacker could use this to cause a denial of
service (system crash) or possibly execute arbitrary code. (CVE-2022-47519)

It was discovered that the Atmel WILC1000 driver in the Linux kernel did
not properly validate offsets, leading to an out-of-bounds read
vulnerability. An attacker could use this to cause a denial of service
(system crash). (CVE-2022-47520)

It was discovered that the Atmel WILC1000 driver in the Linux kernel did
not properly validate specific attributes, leading to a heap-based buffer
overflow. An attacker could use this to cause a denial of service (system
crash) or possibly execute arbitrary code. (CVE-2022-47521)

Lin Ma discovered a race condition in the io_uring subsystem in the Linux
kernel, leading to a null pointer dereference vulnerability. A local
attacker could use this to cause a denial of service (system crash).
(CVE-2023-0468)

It was discovered that the file system writeback functionality in the Linux
kernel contained a user-after-free vulnerability. A local attacker could
possibly use this to cause a denial of service (system crash) or execute
arbitrary code. (CVE-2023-26605)
