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 vulnerability in some
situations. A local attacker could use this to cause a denial of service
(system crash). (CVE-2023-1073)
It was discovered that a memory leak existed in the SCTP protocol
implementation in the Linux kernel. A local attacker could use this to
cause a denial of service (memory exhaustion). (CVE-2023-1074)
It was discovered that the TLS subsystem in the Linux kernel contained a
type confusion vulnerability in some situations. A local attacker could use
this to cause a denial of service (system crash) or possibly expose
sensitive information. (CVE-2023-1075)
It was discovered that the Reliable Datagram Sockets (RDS) protocol
implementation in the Linux kernel contained a type confusion vulnerability
in some situations. An attacker could use this to cause a denial of service
(system crash). (CVE-2023-1078)
Xingyuan Mo discovered that the x86 KVM implementation in the Linux kernel
did not properly initialize some data structures. A local attacker could
use this to expose sensitive information (kernel memory). (CVE-2023-1513)
It was discovered that the NFS implementation in the Linux kernel did not
properly handle pending tasks in some situations. A local attacker could
use this to cause a denial of service (system crash) or expose sensitive
information (kernel memory). (CVE-2023-1652)
It was discovered that the ARM64 EFI runtime services implementation in the
Linux kernel did not properly manage concurrency calls. A local attacker
could use this to cause a denial of service (system crash) or possibly
execute arbitrary code. (CVE-2023-21102)
It was discovered that a race condition existed in Adreno GPU DRM driver in
the Linux kernel, leading to a double-free vulnerability. A local attacker
could use this to cause a denial of service (system crash).
(CVE-2023-21106)
It was discovered that a use-after-free vulnerability existed in the iSCSI
TCP implementation in the Linux kernel. A local attacker could possibly use
this to cause a denial of service (system crash). (CVE-2023-2162)
Kyle Zeng discovered that the class-based queuing discipline implementation
in the Linux kernel contained a type confusion vulnerability in some
situations. An attacker could use this to cause a denial of service (system
crash). (CVE-2023-23454)
Kyle Zeng discovered that the ATM VC queuing discipline implementation in
the Linux kernel contained a type confusion vulnerability in some
situations. An attacker could use this to cause a denial of service (system
crash). (CVE-2023-23455)
It was discovered that the NTFS file system implementation in the Linux
kernel did not properly validate the size of attributes when parsing MFT. A
local attacker could possibly use this to cause a denial of service (system
crash) or expose sensitive information (kernel memory). (CVE-2023-26544)
It was discovered that the NET/ROM protocol implementation in the Linux
kernel contained a race condition in some situations, 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-2023-32269)
