CVE-2023-33203 [MEDIUM] Linux kernel vulnerabilities
Title: Linux kernel vulnerabilities
Summary: Several security issues were fixed in the Linux kernel.
Patryk Sondej and Piotr Krysiuk discovered that a race condition existed in
the netfilter subsystem of the Linux kernel when processing batch requests,
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-2023-32233)
Gwangun Jung discovered that the Quick Fair Queueing scheduler
implementation in the Linux kernel contained an out-of-bounds write
vulnerability. A local attacker could use this to cause a denial of service
(system crash) or possibly execute arbitrary code. (CVE-2023-31436)

CVE-2023-1076 [MEDIUM] Linux kernel (OEM) vulnerabilities
Title: Linux kernel (OEM) vulnerabilities
Summary: Several security issues were fixed in the Linux kernel.
It was discovered that the Traffic-Control Index (TCINDEX) implementation
in the Linux kernel did not properly perform filter deactivation in some
situations. A local attacker could possibly use this to gain elevated
privileges. Please note that with the fix for this CVE, kernel support for
the TCINDEX classifier has been removed. (CVE-2023-1829)
William Zhao discovered that the Traffic Control (TC) subsystem in the
Linux kernel did not properly handle network packet retransmission in
certain situations. A local attacker could use this to cause a denial of
service (kernel deadlock). (CVE-2022-4269)

kernel: Bluetooth: HCI: global out-of-bounds access in net/bluetooth/hci_sync.c
In the Linux kernel through 6.2.8, net/bluetooth/hci_sync.c allows out-of-bounds access because amp_init1[] and amp_init2[] are supposed to have an intentionally invalid element, but do not.
An out-of-bounds (OOB) memory access flaw was found in net/bluetooth/hci_sync.c due to a missing exit patch while in loop in amp_init1[] and amp_init2[]. This issue could allow an attacker to leak internal kernel information.
Mitigation: Mitigation for this issue is either not available or the currently available options don't meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability.

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 refl
