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® 82599 Ethernet Controllers and Adapters may allow an authenticated user to potentially enable denial of service via local access. (CVE-2021-33061)
In do_ipt_get_ctl and do_ipt_set_ctl of ip_tables.c, there is a possible way to leak kernel information due to uninitialized data. This could lead to local information disclosure with system execution privileges needed. User interaction is not needed for exploitation.Product: AndroidVersions: Android kernelAndroid ID: A-120612905References: Upstream kernel (CVE-2021-39636)
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)
Linux Kernel could allow a local attacker to execute arbitrary code on the system, caused by a concurrency use-after-free flaw in the bad_flp_intr function. By executing a specially-crafted program, an attacker could exploit this vulnerability to execute arbitrary code or cause a denial of service condition on the system. (CVE-2022-1652)
In lg_probe and related functions of hid-lg.c and other USB HID files, there is a possible out of bounds read due to improper input validation. This could lead to local information disclosure if a malicious USB HID device were plugged in, with no additional execution privileges needed. User interaction is not needed for exploitation.Product: AndroidVersions: Android kernelAndroid ID: A-188677105References: Upstream kernel (CVE-2022-20132)
In various methods of kernel base drivers, there is a possible out of bounds write due to a heap buffer overflow. 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-182388481References: Upstream kernel (CVE-2022-20166)
drivers/block/floppy.c in the Linux kernel before 5.17.6 is vulnerable to a denial of service, because of a concurrency use-after-free flaw after deallocating raw_cmd in the raw_cmd_ioctl function.
(CVE-2022-33981)
kernel: information leak in copy_page_to_iter() in iov_iter.c (CVE-2022-0850)
kernel: race condition in perf_event_open leads to privilege escalation (CVE-2022-1729)
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.
