these updates will be installed automatically and you do not need to
take any action.

Alternatively, you can install these updates by running:

# /usr/sbin/uptrack-upgrade -y


DESCRIPTION

* CVE-2024-43854: Information leak in Block layer data integrity driver.

A missing variable initialization when using the Block layer data
integrity driver could lead to uninitialised kernel memory being written
to disk. A local attacker could use this flaw to extract sensitive
information.


* CVE-2024-44994: Denial-of-service in IOMMU subsystem.

A logic error when handling pagefaults in IOMMU subsystem could
lead to a kernel crash. A local attacker could use this flaw to
cause a denial-of-service.


* CVE-2024-45018: Information leak in Network packet filtering framework.

A missing variable initialization in the Network packet
filtering framework (Netfilter) driver could lead to use of
uninitialized memory. A local attacker could use this flaw to
extract sensitive information.


* CVE-2024-46695: Permission bypass in NSA SELinux driver.

A logic error when a NFS client tries to change SELinux files context on
a disk exported by a NFS server could lead to permission bypass.


* CVE-2024-49949: Denial-of-service in core networking layer.

Missing checks on maliciously crafted packets from userspace could
cause an underflow leading to a NULL pointer dereference. A local
attacker could use this flaw to cause a denial-of-service.


* CVE-2024-50009: Denial-of-service in CPU Frequency scaling driver.

A missing check when using the CPU Frequency scaling driver could lead
to a NULL pointer dereference. A local attacker could use this flaw to
cause a denial-of-service.


* CVE-2024-50251: Denial-of-service in Network packet filtering framework (Netfilter) driver.

A missing check when using the Network packet filtering framework
(Netfilter) driver could lead to a kernel assertion failure. A local
attacker could use this flaw to cause a denial-of-service.


* Note: Oracle has determined some CVEs are not applicable.

The kernel is not affected by the following CVEs
since the code under consideration is not compiled.

CVE-2024-26615, CVE-2024-45026
