DESCRIPTION

* CVE-2023-39194: Information disclosure when using xfrm subsystem.

A missing check when using xfrm subsystem could lead to an out-of-bounds
access. A local user could use this flaw to leak sensitive information.


* CVE-2023-3773: Information leak in the networking transformation sub-system.

A missing type description in the networking transformation code could lead
to reading four uninitialized bytes.  A local attacker could use this flaw
to leak memory from the kernel heap.


* CVE-2023-42754: Denial-of-service on IPV4 link failure.

A missing check on IPV4 link failure could lead to a NULL pointer
dereference. A local attacker could use this flaw to cause a denial-of-
service.


* CVE-2023-1989: Denial-of-service when unloading the Bluetooth SDIO driver.

A missing clean-up routine to cancel a timer when removing a Bluetooth SDIO
could lead to a use-after-free.  A local, privileged user could use this
flaw to cause a denial-of-service.


* CVE-2023-5178: Privilege escalation in NVMe over Fabrics TCP.

A logic error when using NVMe over Fabrics TCP could lead to a
use-after-free. A remote attacker could use this flaw to escalate
privileges.


* CVE-2023-39192: Out-of-bounds access in Netfilter xt_u32 module.

Incomplete input validation in Netfilter xt_u32 extension module
allows a local privileged user to cause an out-of-bounds read.  This can
lead to a denial-of-service or information disclosure.


* CVE-2023-39193: Out-of-bounds access in Netfilter xt_sctp module.

Incomplete input validation in Netfilter xt_sctp extension module allows a
local user with CAP_NET_ADMIN privileges to cause an out-of-bounds read.  This
can lead to a denial-of-service or information disclosure.


* CVE-2023-39189: Out-of-bounds access in Netfilter OSF over NFNETLINK interface.

Insufficient input validation in the Netfilter OSF over NFNETLINK interface
can lead to an out-of-bounds read.  This can lead to information disclosure.


* CVE-2023-5717: Privilege escalation in the Linux kernel's Performance Events.

A logic error in the Linux kernel's Performance Events could lead to a
heap out-of-bounds write. A local attacker could use this flaw to cause
a denial-of-service or escalate privileges.


* CVE-2023-37453: Denial-of-service in USB core.

A race condition in the USB subsystem could lead to an out-of-bounds read
while handling device descriptors in some situations. A local attacker
could potentially use this flaw to cause a denial-of-service.


* CVE-2023-5158: Denial-of-service in virtio ring.

The host side virtio ring implementation did not properly handle iov
buffers in some situations. A local attacker in a guest VM could use
this flaw to crash the host system.


* CVE-2023-39198: Use-after-free in QXL virtual GPU driver.

A race condition in the QXL virtual GPU driver could lead to a
use-after-free vulnerability. A local attacker could use this flaw
to cause a denial-of-service or potentially escalate privileges.
