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 5.10.162-141.675. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2KERNEL-5.10-2023-025 advisory.

2025-01-21: CVE-2022-48999 was added to this advisory.

2025-01-21: CVE-2022-49014 was added to this advisory.

2025-01-21: CVE-2022-48988 was added to this advisory.

2025-01-21: CVE-2022-48981 was added to this advisory.

2025-01-21: CVE-2022-49015 was added to this advisory.

2025-01-21: CVE-2022-48956 was added to this advisory.

2025-01-21: CVE-2022-48991 was added to this advisory.

2025-01-21: CVE-2022-49017 was added to this advisory.

2025-01-21: CVE-2022-49006 was added to this advisory.

A vulnerability classified as problematic has been found in Linux Kernel. This affects the function fib_nh_match of the file net/ipv4/fib_semantics.c of the component IPv4 Handler. The manipulation leads to out-of-bounds read. It is possible to initiate the attack remotely. It is recommended to apply a patch to fix this issue. The identifier VDB-210357 was assigned to this vulnerability. (CVE-2022-3435)

A vulnerability was found in Linux Kernel. It has been declared as problematic. Affected by this vulnerability is the function follow_page_pte of the file mm/gup.c of the component BPF. The manipulation leads to race condition. The attack can be launched remotely. It is recommended to apply a patch to fix this issue. The identifier VDB-211921 was assigned to this vulnerability. (CVE-2022-3623)

Guests can trigger NIC interface reset/abort/crash via netback It is possible for a guest to trigger a NIC interface reset/abort/crash in a Linux based network backend by sending certain kinds of packets. It appears to be an (unwritten?) assumption in the rest of the Linux network stack that packet protocol headers are all contained within the linear section of the SKB and some NICs behave badly if this is not the case. This has been reported to occur with Cisco (enic) and Broadcom NetXtrem II BCM5780 (bnx2x) though it may be an issue with other NICs/drivers as well. In case the frontend is sending requests with split headers, netback will forward those violating above mentioned assumption to the networking core, resulting in said misbehavior. (CVE-2022-3643)

Guests can trigger deadlock in Linux netback driver T[his CNA information record relates to multiple CVEs;
the text explains which aspects/vulnerabilities correspond to which CVE.] The patch for XSA-392 introduced another issue which might result in a deadlock when trying to free the SKB of a packet dropped due to the XSA-392 handling (CVE-2022-42328). Additionally when dropping packages for other reasons the same deadlock could occur in case of netpoll being active for the interface the xen-netback driver is connected to (CVE-2022-42329). (CVE-2022-42328)

(CVE-2022-42329)

A stack overflow flaw was found in the Linux kernel's SYSCTL subsystem in how a user changes certain kernel parameters and variables. This flaw allows a local user to crash or potentially escalate their privileges on the system. (CVE-2022-4378)

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

ipv6: avoid use-after-free in ip6_fragment() (CVE-2022-48956)

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

drm/shmem-helper: Remove errant put in error path (CVE-2022-48981)

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

memcg: fix possible use-after-free in memcg_write_event_control() (CVE-2022-48988)

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

mm/khugepaged: invoke MMU notifiers in shmem/file collapse paths (CVE-2022-48991)

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

ipv4: Handle attempt to delete multipath route when fib_info contains an nh reference (CVE-2022-48999)

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

tracing: Free buffers when a used dynamic event is removed (CVE-2022-49006)

tipc: re-fetch skb cb after tipc_msg_validate (CVE-2022-49017)

A time-of-check to time-of-use issue exists in io_uring subsystem's IORING_OP_CLOSE operation in the Linux kernel's versions 5.6 - 5.11 (inclusive), which allows a local user to elevate their privileges to root.
Introduced in b5dba59e0cf7e2cc4d3b3b1ac5fe81ddf21959eb, patched in 9eac1904d3364254d622bf2c771c4f85cd435fc2, backported to stable in 788d0824269bef539fe31a785b1517882eafed93. (CVE-2023-1295)

A null pointer dereference issue was found in the can protocol in net/can/af_can.c in the Linux Kernel.
ml_priv may not be initialized in the receive path of CAN frames. This issue could allow a local user to crash the system or cause a denial of service. (CVE-2023-2166)

Tenable has extracted the preceding description block directly from the tested product security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Run 'yum update kernel' to update your system.
