EulerOS 2.0 SP9 : kernel (EulerOS-SA-2022-1969)

high Nessus Plugin ID 162887

Synopsis

The remote EulerOS host is missing multiple security updates.

Description

According to the versions of the kernel packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

 - Insufficient control flow management for the Intel(R) 82599 Ethernet Controllers and Adapters may allow an authenticated user to potentially enable denial of service via local access. (CVE-2021-33061)

 - Product: AndroidVersions: Android kernelAndroid ID: A-173788806References: Upstream kernel (CVE-2021-39713)

 - Non-transparent sharing of branch predictor selectors between contexts in some Intel(R) Processors may allow an authorized user to potentially enable information disclosure via local access. (CVE-2022-0001)

 - Non-transparent sharing of branch predictor within a context in some Intel(R) Processors may allow an authorized user to potentially enable information disclosure via local access. (CVE-2022-0002)

 - A vulnerability was found in the pfkey_register function in net/key/af_key.c in the Linux kernel. This flaw allows a local, unprivileged user to gain access to kernel memory, leading to a system crash or a leak of internal kernel information. (CVE-2022-1353)

 - The root cause of this vulnerability is that the ioctl$DRM_IOCTL_MODE_DESTROY_DUMB can decrease refcount of *drm_vgem_gem_object *(created in *vgem_gem_dumb_create*) concurrently, and *vgem_gem_dumb_create *will access the freed drm_vgem_gem_object. (CVE-2022-1419)

 - An issue was discovered in the Linux Kernel from 4.18 to 4.19, an improper update of sock reference in TCP pacing can lead to memory/netns leak, which can be used by remote clients. (CVE-2022-1678)

 - In mmc_blk_read_single of block.c, there is a possible way to read kernel heap memory due to uninitialized data. This could lead to local information disclosure if reading from an SD card that triggers errors, with no additional execution privileges needed. User interaction is not needed for exploitation.Product:

 - Certain Arm Cortex and Neoverse processors through 2022-03-08 do not properly restrict cache speculation, aka Spectre-BHB. An attacker can leverage the shared branch history in the Branch History Buffer (BHB) to influence mispredicted branches. Then, cache allocation can allow the attacker to obtain sensitive information. (CVE-2022-23960)

 - 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)

 - The Linux kernel before 5.17.2 mishandles seccomp permissions. The PTRACE_SEIZE code path allows attackers to bypass intended restrictions on setting the PT_SUSPEND_SECCOMP flag. (CVE-2022-30594)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected kernel packages.
