| Description: | Summary:
The remote host is missing an update for the 'linux, linux-aws, linux-azure, linux-azure-5.19, linux-kvm, linux-lowlatency, linux-raspi' package(s) announced via the USN-6079-1 advisory.
Vulnerability Insight:
It was discovered that some AMD x86-64 processors with SMT enabled could
speculatively execute instructions using a return address from a sibling
thread. A local attacker could possibly use this to expose sensitive
information. (CVE-2022-27672)
Ziming Zhang discovered that the VMware Virtual GPU DRM 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-2022-36280)
Zheng Wang discovered that the Intel i915 graphics driver in the Linux
kernel did not properly handle certain error conditions, leading to a
double-free. A local attacker could possibly use this to cause a denial of
service (system crash). (CVE-2022-3707)
Haowei Yan discovered that a race condition existed in the Layer 2
Tunneling Protocol (L2TP) implementation in the Linux kernel. A local
attacker could possibly use this to cause a denial of service (system
crash). (CVE-2022-4129)
It was discovered that the NTFS file system implementation in the Linux
kernel contained a null pointer dereference in some situations. A local
attacker could use this to cause a denial of service (system crash).
(CVE-2022-4842)
It was discovered that the NTFS file system implementation in the Linux
kernel did not properly validate attributes in certain situations, leading
to an out-of-bounds write vulnerability. A local attacker could use this to
cause a denial of service (system crash). (CVE-2022-48423)
It was discovered that the NTFS file system implementation in the Linux
kernel did not properly validate attributes in certain situations, leading
to an out-of-bounds read vulnerability. A local attacker could possibly use
this to expose sensitive information (kernel memory). (CVE-2022-48424)
It was discovered that the KSMBD implementation in the Linux kernel did not
properly validate buffer lengths, leading to a heap-based buffer overflow.
A remote attacker could possibly use this to cause a denial of service
(system crash). (CVE-2023-0210)
Kyle Zeng discovered that the IPv6 implementation in the Linux kernel
contained a NULL pointer dereference vulnerability in certain situations. A
local attacker could use this to cause a denial of service (system crash).
(CVE-2023-0394)
Jordy Zomer and Alexandra Sandulescu discovered that syscalls invoking the
do_prlimit() function in the Linux kernel did not properly handle
speculative execution barriers. A local attacker could use this to expose
sensitive information (kernel memory). (CVE-2023-0458)
Jordy Zomer and Alexandra Sandulescu discovered that the Linux kernel did
not properly implement speculative execution barriers in usercopy functions
in certain situations. A local attacker could use this to expose sensitive
information (kernel memory). (CVE-2023-0459)
It was discovered that the Human Interface Device (HID) support driver in
the Linux kernel contained a type confusion ... [Please see the references for more information on the vulnerabilities]
