Summary
It was discovered that the NTFS file system implementation in the Linux
kernel did not properly check buffer indexes 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-2022-48502)
Stonejiajia, Shir Tamari and Sagi Tzadik discovered that the OverlayFS
implementation in the Ubuntu Linux kernel did not properly perform
permission checks in certain situations. A local attacker could possibly
use this to gain elevated privileges. (CVE-2023-2640)
It was discovered that the IP-VLAN network driver for the Linux kernel did
not properly initialize memory in some situations, 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-2023-3090)
Mingi Cho discovered that the netfilter subsystem in the Linux kernel did
not properly validate the status of a nft chain while performing a lookup
by id, leading to a use-after-free vulnerability. An attacker could use
this to cause a denial of service (system crash) or possibly execute
arbitrary code. (CVE-2023-31248)
It was discovered that the Ricoh R5C592 MemoryStick card reader driver in
the Linux kernel contained a race condition during module unload, 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-2023-3141)
Shir Tamari and Sagi Tzadik discovered that the OverlayFS implementation in
the Ubuntu Linux kernel did not properly perform permission checks in
certain situations. A local attacker could possibly use this to gain
elevated privileges. (CVE-2023-32629)
Querijn Voet discovered that a race condition existed in the io_uring
subsystem 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-2023-3389)
It was discovered that the netfilter subsystem in the Linux kernel did not
properly handle some error 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-2023-3390)
Tanguy Dubroca discovered that the netfilter subsystem in the Linux kernel
did not properly handle certain pointer data type, leading to an out-of-
bounds write vulnerability. A privileged attacker could use this to cause a
denial of service (system crash) or possibly execute arbitrary code.
(CVE-2023-35001)

Use after free in io_uring in the Linux Kernel
A use-after-free vulnerability in the Linux Kernel io_uring subsystem can be exploited to achieve local privilege escalation. Racing a io_uring cancel poll request with a linked timeout can cause a UAF in a hrtimer. We recommend upgrading past commit ef7dfac5…

Use-after-free in Linux kernel's netfilter subsystem
A use-after-free vulnerability was found in the Linux kernel's netfilter subsystem in net/netfilter/nf_tables_api.c. Mishandled error handling with NFT_MSG_NEWRULE makes it possible to use a dangling pointer in the same transaction causing a use-after-free vu…
