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.

  - 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)

  - 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)

  - ** DISPUTED ** 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. NOTE: the original discoverer disputes that the overflow can     actually happen. (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)

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