DESCRIPTION

* 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-2024-47685: Remote information leak in IPv6 packet rejection driver.

A missing check when using the IPv6 packet rejection driver could lead
to use of uninitialized memory. A remote attacker could use this flaw to
extract sensitive information.


* CVE-2024-49948, 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-2024-50110: Information leak in Transformation user configuration interface driver.

A logic error when dumping information in the Transformation user
configuration interface driver could lead to use of uninitialized
memory. A local attacker could use this flaw to extract sensitive
information.


* CVE-2024-50142: Denial-of-service in transformation user configuration interface.

A logic error when using the transformation user configuration interface
could lead to an integer overflow. A local attacker could use this flaw
to cause a denial-of-service.


* CVE-2024-50256: Denial-of-service in IPv6 packet rejection driver.

A logic error when using the IPv6 packet rejection driver could lead to
a kernel assertion failure. A local attacker could use this flaw to
cause a denial-of-service.


* CVE-2024-50264: Privilege escalation in Virtual Socket protocol driver.

A missing variable initialization when during loopback communication in
the Virtual Socket protocol driver could lead to a use-after-free. A
local attacker could use this flaw to escalate privileges.
