linux, linux-aws, linux-kvm, linux-lts-xenial vulnerabilities

It was discovered that the Layer 2 Tunneling Protocol (L2TP) implementation
in the Linux kernel contained a race condition when releasing PPPoL2TP
sockets in certain conditions, 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-2022-20567)

It was discovered that the ext4 file system implementation in the Linux
kernel did not properly handle block device modification while it is
mounted. A privileged attacker could use this to cause a denial of service
(system crash) or possibly expose sensitive information. (CVE-2023-34256)

Eric Dumazet discovered that the netfilter subsystem in the Linux kernel
did not properly handle DCCP conntrack buffers in certain situations,
leading to an out-of-bounds read vulnerability. An attacker could possibly
use this to expose sensitive information (kernel memory). (CVE-2023-39197)

It was discovered that a race condition existed in the AppleTalk networking
subsystem of 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-2023-51781)

It was discovered that the ext4 file system implementation in the Linux
kernel did not properly handle the remount operation in certain cases,
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-2024-0775)

Notselwyn discovered that the netfilter subsystem in the Linux kernel did
not properly handle verdict parameters in certain cases, 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-2024-1086)

It was discovered that a race condition existed in the SCSI Emulex
LightPulse Fibre Channel driver in the Linux kernel when unregistering FCF
and re-scanning an HBA FCF table, leading to a null pointer dereference
vulnerability. A local attacker could use this to cause a denial of service
(system crash). (CVE-2024-24855)
