Synopsis

The remote Amazon Linux 2 host is missing a security update.

Description

The version of kernel installed on the remote host is prior to 5.15.93-55.139. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2KERNEL-5.15-2024-037 advisory.

A flaw was found in the Linux kernel's Layer 2 Tunneling Protocol (L2TP). A missing lock when clearing sk_user_data can lead to a race condition and NULL pointer dereference. A local user could use this flaw to potentially crash the system causing a denial of service. (CVE-2022-4129)

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

cpufreq: governor: Use kobject release() method to free dbs_data (CVE-2022-49513)

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

ovl: Use buf flexible array for memcpy() destination (CVE-2022-49743)

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

perf/x86/amd: fix potential integer overflow on shift of a int (CVE-2022-49748)

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

device property: fix of node refcount leak in fwnode_graph_get_next_endpoint() (CVE-2022-49752)

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

dmaengine: Fix double increment of client_count in dma_chan_get() (CVE-2022-49753)

A flaw was found in the Linux kernel, where unauthorized access to the execution of the setuid file with capabilities was found in the Linux kernel's OverlayFS subsystem in how a user copies a capable file from a nosuid mount into another mount. This uid mapping bug allows a local user to escalate their privileges on the system. (CVE-2023-0386)

A memory corruption flaw was found in the Linux kernel's human interface device (HID) subsystem in how a user inserts a malicious USB device. This flaw allows a local user to crash or potentially escalate their privileges on the system. (CVE-2023-1073)

A use-after-free flaw was found in nfsd4_ssc_setup_dul in fs/nfsd/nfs4proc.c in the NFS filesystem in the Linux Kernel. This issue could allow a local attacker to crash the system or it may lead to a kernel information leak problem. (CVE-2023-1652)

In the Linux kernel 6.0.8, there is a use-after-free in inode_cgwb_move_to_attached in fs/fs-writeback.c, related to __list_del_entry_valid. (CVE-2023-26605)

A flaw was found in the Framebuffer Console (fbcon) in the Linux Kernel. When providing a font->width and font->height greater than 32 to the fbcon_set_font, since there are no checks in place, a shift-out-of- bounds occurs, leading to undefined behavior and possible denial of service. (CVE-2023-3161)

A use-after-free flaw was found in vcs_read in drivers/tty/vt/vc_screen.c in vc_screen in the Linux Kernel. In this flaw an attacker with local user access may lead to a system crash or a leak of internal kernel information. (CVE-2023-3567)

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

bpf: Skip invalid kfunc call in backtrack_insn (CVE-2023-52928)

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

vc_screen: move load of struct vc_data pointer in vcs_read() to avoid UAF (CVE-2023-52973)

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

efi: fix potential NULL deref in efi_mem_reserve_persistent (CVE-2023-52976)
