EulerOS Virtualization 3.0.6.0 : kernel (EulerOS-SA-2023-2252)

high Nessus Plugin ID 177184

Synopsis

The remote EulerOS Virtualization host is missing multiple security updates.

Description

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

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.(CVE-2022-20166)

In lock_sock_nested of sock.c, there is a possible use after free 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.(CVE-2022-20154)

An out-of-bounds access issue was found in the Linux kernel networking subsystem in the way raw packet sockets (AF_PACKET) used PACKET_COPY_THRESH and mmap operations. A local attacker with CAP_NET_RAW capability could use this flaw to trigger a buffer overflow resulting in a system crash or privilege escalation.(CVE-2022-20368)

A race condition in the Linux kernel before 5.6.2 between the VT_DISALLOCATE ioctl and closing/opening of ttys could lead to a use-after-free.(CVE-2020-36557)

A race condition in the Linux kernel before 5.5.7 involving VT_RESIZEX could lead to a NULL pointer dereference and general protection fault.(CVE-2020-36558)

An issue was discovered in the Linux kernel through 5.18.9. A type confusion bug in nft_set_elem_init (leading to a buffer overflow) could be used by a local attacker to escalate privileges, a different vulnerability than CVE-2022-32250. (The attacker can obtain root access, but must start with an unprivileged user namespace to obtain CAP_NET_ADMIN access.) This can be fixed in nft_setelem_parse_data in net/netfilter/nf_tables_api.c.(CVE-2022-34918)

When setting font with malicous data by ioctl cmd PIO_FONT,kernel will write memory out of bounds.(CVE-2021-33656)

An information leak flaw was found in NFS over RDMA in the net/sunrpc/xprtrdma/rpc_rdma.c in the Linux Kernel. This flaw allows an attacker with normal user privileges to leak kernel information.(CVE-2022-0812)

nfqnl_mangle in net/netfilter/nfnetlink_queue.c in the Linux kernel through 5.18.14 allows remote attackers to cause a denial of service (panic) because, in the case of an nf_queue verdict with a one-byte nfta_payload attribute, an skb_pull can encounter a negative skb-len.(CVE-2022-36946)

An integer coercion error was found in the openvswitch kernel module. Given a sufficiently large number of actions, while copying and reserving memory for a new action of a new flow, the reserve_sfa_size() function does not return -EMSGSIZE as expected, potentially leading to an out-of-bounds write access. This flaw allows a local user to crash or potentially escalate their privileges on the system.(CVE-2022-2639)

A use-after-free flaw was found in route4_change in the net/sched/cls_route.c filter implementation in the Linux kernel. This flaw allows a local user to crash the system and possibly lead to a local privilege escalation problem.(CVE-2022-2588)

Dm-verity is used for extending root-of-trust to root filesystems. LoadPin builds on this property to restrict module/firmware loads to just the trusted root filesystem. Device-mapper table reloads currently allow users with root privileges to switch out the target with an equivalent dm-linear target and bypass verification till reboot. This allows root to bypass LoadPin and can be used to load untrusted and unverified kernel modules and firmware, which implies arbitrary kernel execution and persistence for peripherals that do not verify firmware updates. We recommend upgrading past commit 4caae58406f8ceb741603eee460d79bacca9b1b5(CVE-2022-2503)

When sending malicous data to kernel by ioctl cmd FBIOPUT_VSCREENINFO,kernel will write memory out of bounds.(CVE-2021-33655)

An issue was discovered in the Linux kernel through 5.18.14. xfrm_expand_policies in net/xfrm/xfrm_policy.c can cause a refcount to be dropped twice.(CVE-2022-36879)

mm/rmap.c in the Linux kernel before 5.19.7 has a use-after-free related to leaf anon_vma double reuse.(CVE-2022-42703)

roccat_report_event in drivers/hid/hid-roccat.c in the Linux kernel through 5.19.12 has a race condition and resultant use-after-free in certain situations where a report is received while copying a report- value is in progress.(CVE-2022-41850)

An issue was discovered in include/asm-generic/tlb.h in the Linux kernel before 5.19. Because of a race condition (unmap_mapping_range versus munmap), a device driver can free a page while it still has stale TLB entries. This only occurs in situations with VM_PFNMAP VMAs.(CVE-2022-39188)

An issue was found in the Linux kernel in nf_conntrack_irc where the message handling can be confused and incorrectly matches the message. A firewall may be able to be bypassed when users are using unencrypted IRC with nf_conntrack_irc configured.(CVE-2022-2663)

A race condition was found in the Linux kernel's IP framework for transforming packets (XFRM subsystem) when multiple calls to xfrm_probe_algs occurred simultaneously. This flaw could allow a local attacker to potentially trigger an out-of-bounds write or leak kernel heap memory by performing an out-of-bounds read and copying it into a socket.(CVE-2022-3028)

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)

A flaw was found in the Linux kernel implementation of proxied virtualized TPM devices. On a system where virtualized TPM devices are configured (this is not the default) a local attacker can create a use-after- free and create a situation where it may be possible to escalate privileges on the system.(CVE-2022-2977)

A use-after-free flaw was found in nf_tables cross-table in the net/netfilter/nf_tables_api.c function in the Linux kernel. This flaw allows a local, privileged attacker to cause a use-after-free problem at the time of table deletion, possibly leading to local privilege escalation.(CVE-2022-2586)

An out-of-bounds read flaw was found in the Linux kernels TeleTYpe subsystem. The issue occurs in how a user triggers a race condition using ioctls TIOCSPTLCK and TIOCGPTPEER and TIOCSTI and TCXONC with leakage of memory in the flush_to_ldisc function. This flaw allows a local user to crash the system or read unauthorized random data from memory.(CVE-2022-1462)

A vulnerability classified as critical was found in Linux Kernel (Operating System) (affected version unknown). Affected by this vulnerability is some unknown processing of the component Cache Handler. There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.(CVE-2022-20565)
