high Nessus Plugin ID 208541

Synopsis

The remote CentOS Linux host is missing one or more security updates.

Description

The remote CentOS Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2022:0592 advisory.

 - In do_epoll_ctl and ep_loop_check_proc of eventpoll.c, there is a possible use after free due to a logic error. This could lead to local escalation of privilege with no additional execution privileges needed.
 User interaction is not needed for exploitation.Product: AndroidVersions: Android kernelAndroid ID:
 A-147802478References: Upstream kernel (CVE-2020-0466)

 - In unix_scm_to_skb of af_unix.c, there is a possible use after free bug due to a race condition. This could lead to local escalation of privilege with System execution privileges needed. User interaction is not needed for exploitation.Product: AndroidVersions: Android kernelAndroid ID: A-196926917References:
 Upstream kernel (CVE-2021-0920)

 - A data leak flaw was found in the way XFS_IOC_ALLOCSP IOCTL in the XFS filesystem allowed for size increase of files with unaligned size. A local attacker could use this flaw to leak data on the XFS filesystem otherwise not accessible to them. (CVE-2021-4155)

 - A random memory access flaw was found in the Linux kernel's GPU i915 kernel driver functionality in the way a user may run malicious code on the GPU. This flaw allows a local user to crash the system or escalate their privileges on the system. (CVE-2022-0330)

 - The vmwgfx driver contains a local privilege escalation vulnerability that allows unprivileged users to gain access to files opened by other processes on the system through a dangling 'file' pointer.
 (CVE-2022-22942)

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