Alternatively, you can install these updates by running:

# /usr/sbin/uptrack-upgrade -y


DESCRIPTION

* CVE-2024-1085: Use-after-free in the Netfilter nf_tables subsystem.

A double-free exists in the kernel's Netfilter nf_tables component. A local
user can use this to cause a denial-of-service.


* CVE-2023-32247: Denial-of-service in kernel SMB server.

The kernel implementation of SMB server did not properly handle session
setup requests. A remote attacker could use this vulnerability to cause
a denial-of-service.


* CVE-2024-1086: Privilege escalation in netfilter subsystem.

Missing check on user input in netfilter subsystem could lead to a
double free. A local attacker could use this flaw to cause a denial-
of-service or escalate privilege.


* CVE-2024-24855: Denial-of-service when using scsi device driver.

A locking error when using scsi device driver could lead to a NULL
pointer dereference. A local attacker could use this flaw to cause a
denial-of-service.


* Note: Oracle has determined that CVE-2023-23000 is not applicable.

A logic error when handling error conditions in NVIDIA Tegra XUSB pad
controller driver could lead to a NULL pointer dereference. A local
attacker could use this flaw to cause a denial-of-service.

The kernel is not affected by CVE-2023-23000 since the code under
consideration is not compiled.
