DESCRIPTION

* CVE-2023-2235: Use-after-free in Performance Events subsystem.

Incorrect logic in the kernel's Performance Events subsystem can lead to a
use-after-free. This can allow a local user to escalate privileges.

* CVE-2023-32233: Use-after-free in Netfilter nf_tables packet classification framework.

Incorrect handling of anonymous sets in the Netfilter nf_tables packet
classification framework can lead to a use-after-free. This can allow a
local unprivileged user to perform arbitrary access to kernel memory and
escalate privileges.

* CVE-2023-2002: Insufficient capability check in the Bluetooth HCI sockets subsystem.

An insufficient capability check in the Bluetooth HCI sockets subsystem can
allow an unprivileged program to mark a socket as trusted. This can allow
escalation of privileges, denial-of-service and information leak.

* CVE-2023-28466: Race condition in Transport Layer Security subsystem.

A race condition in the Transport Layer Security (TLS) subsystem between
getsockopt() and setsockopt() operations can lead to use-after-free or null
dereference. This can allow a local user to cause denial-of-service.

* CVE-2023-2194: Insufficient input validation in APM X-Gene SoC I2C SLIMpro.

Insufficient user input validation in the APM X-Gene SoC I2C SLIMpro device
driver could allow writing beyond the end of a buffer. This could allow a
local privileged user to crash the system or execute incorrect code.

* CVE-2023-2124: Denial-of-service in XFS file system during image restoration.

Insufficient checks in XFS during image restoration after a failure
with a dirty log journal can lead to out-of-bounds memory access flaw.
A local attacker can use this flaw to cause denial-of-service or to
escalate their privileges.
