infrastructure implementation in the Linux kernel contained a race
condition. An attacker in a guest VM could possibly use this to cause a
denial of service (paravirtualized device unavailability). (CVE-2023-34324)

Zheng Wang discovered a use-after-free in the Renesas Ethernet AVB driver
in the Linux kernel during device removal. A privileged attacker could use
this to cause a denial of service (system crash). (CVE-2023-35827)

Tom Dohrmann discovered that the Secure Encrypted Virtualization (SEV)
implementation for AMD processors in the Linux kernel contained a race
condition when accessing MMIO registers. A local attacker in a SEV guest VM
could possibly use this to cause a denial of service (system crash) or
possibly execute arbitrary code. (CVE-2023-46813)

It was discovered that the io_uring subsystem in the Linux kernel contained
a race condition, leading to a null pointer dereference vulnerability. A
local attacker could use this to cause a denial of service (system crash).
(CVE-2023-46862)

It was discovered that the netfilter subsystem in the Linux kernel did not
properly validate inner tunnel netlink attributes, leading to a null
pointer dereference vulnerability. A local attacker could use this to cause
a denial of service (system crash). (CVE-2023-5972)

It was discovered that the TLS subsystem in the Linux kernel did not
properly perform cryptographic operations in some situations, leading to a
null pointer dereference vulnerability. A local attacker could use this to
cause a denial of service (system crash) or possibly execute arbitrary
code. (CVE-2023-6176)

Jann Horn discovered that a race condition existed in the Linux kernel when
handling io_uring over sockets, 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-2023-6531)

Xingyuan Mo discovered that the netfilter subsystem in the Linux kernel did
not properly handle dynset expressions passed from userspace, leading to a
null pointer dereference vulnerability. A local attacker could use this to
cause a denial of service (system crash). (CVE-2023-6622)

It was discovered that the TIPC protocol implementation in the Linux kernel
did not properly handle locking during tipc_crypto_key_revoke() operations.
A local attacker could use this to cause a denial of service (kernel
deadlock). (CVE-2024-0641)");
