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 5.10.147-133.644. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2KERNEL-5.10-2022-021 advisory.

2024-08-01: CVE-2022-48660 was added to this advisory.

2024-08-01: CVE-2022-48643 was added to this advisory.

2024-08-01: CVE-2022-48631 was added to this advisory.

2024-08-01: CVE-2022-48644 was added to this advisory.

2024-08-01: CVE-2022-48641 was added to this advisory.

2024-08-01: CVE-2022-48642 was added to this advisory.

2024-06-06: CVE-2022-48651 was added to this advisory.

2024-05-23: CVE-2022-3544 was added to this advisory.

A vulnerability was found in the fs/inode.c:inode_init_owner() function logic of the LInux kernel that allows local users to create files for the XFS file-system with an unintended group ownership and with group execution and SGID permission bits set, in a scenario where a directory is SGID and belongs to a certain group and is writable by a user who is not a member of this group. This can lead to excessive permissions granted in case when they should not. This vulnerability is similar to the previous CVE-2018-13405 and adds the missed fix for the XFS. (CVE-2021-4037)

A flaw was found in the Linux kernel. The existing KVM SEV API has a vulnerability that allows a non-root (host) user-level application to crash the host kernel by creating a confidential guest VM instance in AMD CPU that supports Secure Encrypted Virtualization (SEV). (CVE-2022-0171)

A use-after-free flaw was found in the Linux kernel's Unix socket Garbage Collection and io_uring. This flaw allows a local user to crash or potentially escalate their privileges on the system. (CVE-2022-2602)

Found Linux Kernel flaw in the i740 driver. The Userspace program could pass any values to the driver through ioctl() interface. The driver doesn't check the value of 'pixclock', so it may cause a divide by zero error. (CVE-2022-3061)

A vulnerability, which was classified as problematic, was found in Linux Kernel. Affected is the function damon_sysfs_add_target of the file mm/damon/sysfs.c of the component Netfilter. The manipulation leads to memory leak. It is recommended to apply a patch to fix this issue. The identifier of this vulnerability is VDB-211044. (CVE-2022-3544)

An issue was discovered in the Linux kernel before 5.19. In pxa3xx_gcu_write in drivers/video/fbdev/pxa3xx-gcu.c, the count parameter has a type conflict of size_t versus int, causing an integer overflow and bypassing the size check. After that, because it is used as the third argument to copy_from_user(), a heap overflow may occur. (CVE-2022-39842)

This vulnerability allows local attackers to disclose sensitive information on affected installations of the Linux Kernel 6.0-rc2. An attacker must first obtain the ability to execute high-privileged code on the target system in order to exploit this vulnerability. The specific flaw exists within the nft_osf_eval function. The issue results from the lack of proper initialization of memory prior to accessing it. An attacker can leverage this in conjunction with other vulnerabilities to execute arbitrary code in the context of the kernel. Was ZDI-CAN-18540. (CVE-2022-42432)

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

ext4: fix bug in extents parsing when eh_entries == 0 and eh_depth > 0 (CVE-2022-48631)

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

net/sched: taprio: avoid disabling offload when it was never enabled (CVE-2022-48644)

In the Linux kernel, the following vulnerability has been resolved: ipvlan: Fix out-of-bound bugs caused by unset skb->mac_header If an AF_PACKET socket is used to send packets through ipvlan and the default xmit function of the AF_PACKET socket is changed from dev_queue_xmit() to packet_direct_xmit() via setsockopt() with the option name of PACKET_QDISC_BYPASS, the skb->mac_header may not be reset and remains as the initial value of 65535, this may trigger slab-out-of-bounds bugs as following: (CVE-2022-48651)

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

netfilter: nfnetlink_osf: fix possible bogus match in nf_osf_find() (CVE-2022-48654)

vfio/type1: Unpin zero pages (CVE-2022-48700)

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.
