A use-after-free vulnerability in the Linux kernel's netfilter: nf_tables component can be exploited to achieve local privilege escalation.
Addition and removal of rules from chain bindings within the same transaction causes leads to use-after-free.
We recommend upgrading past commit f15f29fd4779be8a418b66e9d52979bb6d6c2325.

A use-after-free vulnerability in the Linux kernel's netfilter: nf_tables component can be exploited to achieve local privilege escalation.
Addition and removal of rules from chain bindings within the same transaction causes leads to use-after-free.
We recommend upgrading past commit f15f29fd4779be8a418b66e9d52979bb6d6c2325.
A use-after-free vulnerability was found in net/netfilter/nf_tables_api.c in the netfilter component in the Linux Kernel. This flaw can be exploited to achieve local privilege escalation. Adding and removing rules from chain bindings within the same transaction leads to a use-after-free issue.

FAQ: Is Azure Linux the only Microsoft product that includes this open-source library and is therefore potentially affected by this vulnerability?
One of the main benefits to our customers who choose to use the Azure Linux distro is the commitment to keep it up to date with the most recent and most secure versions of the open source libraries with which the distro is composed. Microsoft is committed to transparency in this work which is why we began publishing CSAF/VEX in October 2025. See this blog post for more information. If impact to additional products is identified, we will update the CVE to reflect this.

Ross Lagerwall discovered that the Xen netback backend driver in the Linux
kernel did not properly handle certain unusual packets from a
paravirtualized network frontend, leading to a buffer overflow. An attacker
in a guest VM could use this to cause a denial of service (host system
crash) or possibly execute arbitrary code. (CVE-2023-34319)
Bien Pham discovered that the netfiler subsystem in the Linux kernel
contained a race condition, leading to a use-after-free vulnerability. A

possibly execute arbitrary code. (CVE-2023-4244)

It was discovered that the IPv6 implementation in the Linux kernel
contained a high rate of hash collisions in connection lookup table. A
remote attacker could use this to cause a denial of service (excessive CPU
consumption). (CVE-2023-1206)
Daniel Trujillo, Johannes Wikner, and Kaveh Razavi discovered that some AMD
processors utilising speculative execution and branch prediction may allow
unauthorised memory reads via a speculative side-channel attack. A local
attacker could use this to expose sensitive information, including kernel
memory. (CVE-2023-20569)

CVE-2023-5197 [MEDIUM] CWE-416 GHSA-5xr7-jj63-cqf7: A use-after-free vulnerability in the Linux kernel's netfilter: nf_tables component can be exploited to achieve local privilege escalation
A use-after-free vulnerability in the Linux kernel's netfilter: nf_tables component can be exploited to achieve local privilege escalation.
Addition and removal of rules from chain bindings within the same transaction causes leads to use-after-free.
We recommend upgrading past commit f15f29fd4779be8a418b66e9d52979bb6d6c2325.
