Summary
It was discovered that the Traffic-Control Index (TCINDEX) implementation
in the Linux kernel did not properly perform filter deactivation in some
situations. A local attacker could possibly use this to gain elevated
privileges. Please note that with the fix for this CVE, kernel support for
the TCINDEX classifier has been removed. (CVE-2023-1829)
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 OverlayFS implementation in the Linux kernel did
not properly handle copy up operation in some conditions. A local attacker
could possibly use this to gain elevated privileges. (CVE-2023-0386)
David Hildenbrand discovered that a race condition existed in the memory
manager of the Linux kernel when handling copy-on-write with shared memory
pages. A local attacker could use this to cause a denial of service (system
crash) or execute arbitrary code. (CVE-2022-2590)
It was discovered that the sound subsystem in the Linux kernel contained a
race condition in some situations. A local attacker could use this to cause
a denial of service (system crash). (CVE-2022-3303)
Gwnaun Jung discovered that the SFB packet scheduling implementation 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-2022-3586)
It was discovered that a race condition existed in the EFI capsule loader
driver in 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-2022-40307)
Zheng Wang and Zhuorao Yang discovered that the RealTek RTL8712U wireless
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-2022-4095)
It was discovered that the USB core subsystem in the Linux kernel did not
properly handle nested reset events. A local attacker with physical access
could plug in a specially crafted USB device to cause a denial of service
(kernel deadlock). (CVE-2022-4662)
It was discovered that a race condition existed in the Xen transport layer
implementation for the 9P file system protocol in the Linux kernel, leading
to a use-after-free vulnerability. A local attacker could use this to cause
a denial of service (guest crash) or expose sensitive information (guest
kernel memory). (CVE-2023-1859)
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)
Lianhui Tang discovered that the MPLS implementation in the Linux kernel
did not properly handle certain sysctl allocation failure conditions,
leading to a double-free vulnerability. An attacker could use this to cause
a denial of service or possibly execute arbitrary code. (CVE-2023-26545)
