EulerOS 2.0 SP10 : kernel (EulerOS-SA-2023-2383)

high Nessus Plugin ID 178361

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 :

 - Intel microprocessor generations 6 to 8 are affected by a new Spectre variant that is able to bypass their retpoline mitigation in the kernel to leak arbitrary data. An attacker with unprivileged user access can hijack return instructions to achieve arbitrary speculative code execution under certain microarchitecture-dependent conditions. (CVE-2022-29901)

 - A speculative pointer dereference problem exists in the Linux Kernel on the do_prlimit() function. The resource argument value is controlled and is used in pointer arithmetic for the 'rlim' variable and can be used to leak the contents. We recommend upgrading past version 6.1.8 or commit 739790605705ddcf18f21782b9c99ad7d53a8c11 (CVE-2023-0458)

 - A use-after-free vulnerability was found in iscsi_sw_tcp_session_create in drivers/scsi/iscsi_tcp.c in SCSI sub-component in the Linux Kernel. In this flaw an attacker could leak kernel internal information.
 (CVE-2023-2162)

 - A vulnerability was found in compare_netdev_and_ip in drivers/infiniband/core/cma.c in RDMA in the Linux Kernel. The improper cleanup results in out-of-boundary read, where a local user can utilize this problem to crash the system or escalation of privilege. (CVE-2023-2176)

 - A null pointer dereference issue was found in the sctp network protocol in net/sctp/stream_sched.c in Linux Kernel. If stream_in allocation is failed, stream_out is freed which would further be accessed. A local user could use this flaw to crash the system or potentially cause a denial of service.
 (CVE-2023-2177)

 - An out-of-bounds write vulnerability was found in the Linux kernel's SLIMpro I2C device driver. The userspace 'data->block[0]' variable was not capped to a number between 0-255 and was used as the size of a memcpy, possibly writing beyond the end of dma_buffer. This flaw could allow a local privileged user to crash the system or potentially achieve code execution. (CVE-2023-2194)

 - Rejected reason: This CVE ID has been rejected or withdrawn by its CVE Numbering Authority because it was the duplicate of CVE-2023-31436. (CVE-2023-2248)

 - A denial of service problem was found, due to a possible recursive locking scenario, resulting in a deadlock in table_clear in drivers/md/dm-ioctl.c in the Linux Kernel Device Mapper-Multipathing sub- component. (CVE-2023-2269)

 - Rejected reason: DO NOT USE THIS CANDIDATE NUMBER. ConsultIDs: CVE-2023-33203. Reason: This candidate is a reservation duplicate of CVE-2023-33203. Notes: All CVE users should reference CVE-2023-33203 instead of this candidate. All references and descriptions in this candidate have been removed to prevent accidental usage. (CVE-2023-2483)

 - qfq_change_class in net/sched/sch_qfq.c in the Linux kernel before 6.2.13 allows an out-of-bounds write because lmax can exceed QFQ_MIN_LMAX. (CVE-2023-31436)

 - In the Linux kernel through 6.3.1, a use-after-free in Netfilter nf_tables when processing batch requests can be abused to perform arbitrary read and write operations on kernel memory. Unprivileged local users can obtain root privileges. This occurs because anonymous sets are mishandled. (CVE-2023-32233)

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.
