Synopsis

The remote Amazon Linux 2023 host is missing a security update.

Description

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2024-517 advisory.

In the Linux kernel, the following vulnerability has been resolved:

drm: Don't unref the same fb many times by mistake due to deadlock handling (CVE-2023-52486)

In the Linux kernel, the following vulnerability has been resolved:

mm/sparsemem: fix race in accessing memory_section->usage (CVE-2023-52489)

In the Linux kernel, the following vulnerability has been resolved:

dmaengine: fix NULL pointer in channel unregistration function (CVE-2023-52492)

In the Linux kernel, the following vulnerability has been resolved:

PM: sleep: Fix possible deadlocks in core system-wide PM code (CVE-2023-52498)

In the Linux kernel, the following vulnerability has been resolved:

ceph: fix deadlock or deadcode of misusing dget() (CVE-2023-52583)

In the Linux kernel, the following vulnerability has been resolved:

PM / devfreq: Fix buffer overflow in trans_stat_show (CVE-2023-52614)

In the Linux kernel, the following vulnerability has been resolved:

hwrng: core - Fix page fault dead lock on mmap-ed hwrng (CVE-2023-52615)

In the Linux kernel, the following vulnerability has been resolved:

pstore/ram: Fix crash when setting number of cpus to an odd number (CVE-2023-52619)

In the Linux kernel, the following vulnerability has been resolved:

bpf: Check rcu_read_lock_trace_held() before calling bpf map helpers (CVE-2023-52621)

In the Linux kernel, the following vulnerability has been resolved:

ext4: avoid online resizing failures due to oversized flex bg (CVE-2023-52622)

In the Linux kernel, the following vulnerability has been resolved:

SUNRPC: Fix a suspicious RCU usage warning (CVE-2023-52623)

In the Linux kernel, the following vulnerability has been resolved:

pipe: wakeup wr_wait after setting max_usage (CVE-2023-52672)

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

The nft_verdict_init() function allows positive values as drop error within the hook verdict, and hence the nf_hook_slow() function can cause a double free vulnerability when NF_DROP is issued with a drop error which resembles NF_ACCEPT.

We recommend upgrading past commit f342de4e2f33e0e39165d8639387aa6c19dff660. (CVE-2024-1086)

In rds_recv_track_latency in net/rds/af_rds.c in the Linux kernel through 6.7.1, there is an off-by-one error for an RDS_MSG_RX_DGRAM_TRACE_MAX comparison, resulting in out-of-bounds access. (CVE-2024-23849)
