Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 22.04 LTS:
linux-image-5.15.0-1045-azure 5.15.0-1045.52
linux-image-5.15.0-1045-azure-fde 5.15.0-1045.52.1
linux-image-azure-fde-lts-22.04 5.15.0.1045.52.23
linux-image-azure-lts-22.04 5.15.0.1045.41

Ubuntu 20.04 LTS:
linux-image-5.15.0-1045-azure 5.15.0-1045.52~20.04.1
linux-image-azure 5.15.0.1045.52~20.04.34
linux-image-azure-cvm 5.15.0.1045.52~20.04.34

After a standard system update you need to reboot your computer to make
all the necessary changes.

ATTENTION: Due to an unavoidable ABI change the kernel updates have
been given a new version number, which requires you to recompile and
reinstall all third party kernel modules you might have installed.
Unless you manually uninstalled the standard kernel metapackages
(e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual,
linux-powerpc), a standard system upgrade will automatically perform
this as well.

CVE-2023-3777

A use-after-free vulnerability in the Linux kernel's netfilter: nf_tables component can be exploited to achieve local privilege escalation. When nf_tables_delrule() is flushing table rules, it is not checked whether the chain is bound and the chain's owner rule can also release the objects in certain circumstances. We recommend upgrading past commit 6eaf41e87a223ae6f8e7a28d6e78384ad7e407f8.

CVE-2023-4015

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

Debian Security Advisory 5475-1

Debian Linux Security Advisory 5475-1 - Daniel Moghimi discovered Gather Data Sampling (GDS), a hardware vulnerability for Intel CPUs which allows unprivileged speculative access to data which was previously stored in vector registers. This mitigation requires updated CPU microcode provided in the intel-microcode package. Daniel Trujillo, Johannes Wikner and Kaveh Razavi discovered INCEPTION, also known as Speculative Return Stack Overflow (SRSO), a transient execution attack that leaks arbitrary data on all AMD Zen CPUs. An attacker can mis-train the CPU BTB to predict non-architectural CALL instructions in kernel space and use this to control the speculative target of a subsequent kernel RET, potentially leading to information disclosure via a speculative side-channel.

gRPC contains a vulnerability that allows hpack table accounting errors could lead to unwanted disconnects between clients and servers in exceptional cases/ Three vectors were found that allow the following DOS attacks: - Unbounded memory buffering in the HPACK parser - Unbounded CPU consumption in the HPACK parser The unbounded CPU consumption is down to a copy that occurred per-input-block in the parser, and because that could be unbounded due to the memory copy bug we end up with an O(n^2) parsing loop, with n selected by the client. The unbounded memory buffering bugs: - The header size limit check was behind the string reading code, so we needed to first buffer up to a 4 gigabyte string before rejecting it as longer than 8 or 16kb. - HPACK varints have an encoding quirk whereby an infinite number of 0’s can be added at the start of an integer. gRPC’s hpack parser needed to read all of them before concluding a parse. - gRPC’s metadata overflow check was performed per frame, so ...

Zenbleed: New Flaw in AMD Zen 2 Processors Puts Encryption Keys and Passwords at Risk

A new security vulnerability has been discovered in AMD's Zen 2 architecture-based processors that could be exploited to extract sensitive data such as encryption keys and passwords. Discovered by Google Project Zero researcher Tavis Ormandy, the flaw – codenamed Zenbleed and tracked as CVE-2023-20593 (CVSS score: 6.5) – allows data exfiltration at the rate of 30 kb per core, per second. The

CVE-2023-32248: cve-details

A flaw was found in the Linux kernel's ksmbd, a high-performance in-kernel SMB server. The specific flaw exists within the handling of SMB2_TREE_CONNECT and SMB2_QUERY_INFO commands. The issue results from the lack of proper validation of a pointer prior to accessing it. An attacker can leverage this vulnerability to create a denial-of-service condition on the system.

CVE-2023-3776

A use-after-free vulnerability in the Linux kernel's net/sched: cls_fw component can be exploited to achieve local privilege escalation. If tcf_change_indev() fails, fw_set_parms() will immediately return an error after incrementing or decrementing the reference counter in tcf_bind_filter(). If an attacker can control the reference counter and set it to zero, they can cause the reference to be freed, leading to a use-after-free vulnerability. We recommend upgrading past commit 0323bce598eea038714f941ce2b22541c46d488f.

CVE-2023-3611

An out-of-bounds write vulnerability in the Linux kernel's net/sched: sch_qfq component can be exploited to achieve local privilege escalation. The qfq_change_agg() function in net/sched/sch_qfq.c allows an out-of-bounds write because lmax is updated according to packet sizes without bounds checks. We recommend upgrading past commit 3e337087c3b5805fe0b8a46ba622a962880b5d64.

CVE-2023-3610

A use-after-free vulnerability in the Linux kernel's netfilter: nf_tables component can be exploited to achieve local privilege escalation. Flaw in the error handling of bound chains causes a use-after-free in the abort path of NFT_MSG_NEWRULE. The vulnerability requires CAP_NET_ADMIN to be triggered. We recommend upgrading past commit 4bedf9eee016286c835e3d8fa981ddece5338795.

CVE-2023-3609

A use-after-free vulnerability in the Linux kernel's net/sched: cls_u32 component can be exploited to achieve local privilege escalation. If tcf_change_indev() fails, u32_set_parms() will immediately return an error after incrementing or decrementing the reference counter in tcf_bind_filter().
