CVE-2023-6817

A use-after-free vulnerability in the Linux kernel's netfilter: nf_tables component can be exploited to achieve local privilege escalation.

The function nft_pipapo_walk did not skip inactive elements during set walk which could lead double deactivations of PIPAPO (Pile Packet Policies) elements, leading to use-after-free.

We recommend upgrading past commit 317eb9685095678f2c9f5a8189de698c5354316a.

A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code.(CVE-2024-1085)

Notselwyn discovered that the netfilter subsystem in the Linux kernel did not properly handle verdict parameters in certain cases, leading to a use- after-free vulnerability. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code.(CVE-2024-1086)

In the Linux kernel, the following vulnerability has been resolved: net: qualcomm: rmnet: fix global oob in rmnet_policy The variable rmnet_link_ops assign a bigger maxtype which leads to a global out-of- bounds read when parsing the netlink attributes. (CVE-2024-26597)

The kernel packages contain the Linux kernel, the core of any Linux operating system.
