Amazon Linux 2 : kernel (ALASKERNEL-5.4-2022-026)

Description

The version of kernel installed on the remote host is prior to 5.4.196-108.356. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2KERNEL-5.4-2022-026 advisory. - Improper Update of Reference Count vulnerability in net/sched of Linux Kernel allows local attacker to cause privilege escalation to root. This issue affects: Linux Kernel versions prior to 5.18; version 4.14 and later versions. (CVE-2022-29581) - A kernel information leak flaw was identified in the scsi_ioctl function in drivers/scsi/scsi_ioctl.c in the Linux kernel. This flaw allows a local attacker with a special user privilege (CAP_SYS_ADMIN or CAP_SYS_RAWIO) to create issues with confidentiality. (CVE-2022-0494) - A memory leak flaw was found in the Linux kernel's DMA subsystem, in the way a user calls DMA_FROM_DEVICE. This flaw allows a local user to read random memory from the kernel space. (CVE-2022-0854) - A race condition was found the Linux kernel in perf_event_open() which can be exploited by an unprivileged user to gain root privileges. The bug allows to build several exploit primitives such as kernel address information leak, arbitrary execution, etc. (CVE-2022-1729) - The SUNRPC subsystem in the Linux kernel through 5.17.2 can call xs_xprt_free before ensuring that sockets are in the intended state. (CVE-2022-28893) Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
