ABB is aware of public reports of a vulnerabilities in product versions listed as affected in this advisory. An attacker who successfully exploited these vulnerabilities could cause the product to stop, make the product inacces-sible, take remote control of the product or insert and run arbitrary code. As part of ABB product lifecycle policy, once a product transitions to end-of-life, we discontinue maintenance, security patches, and technical support to focus on current and future technologies. While the product will continue to function, we strongly recommend implementing mitigations defined in this document, such as using a private APN cellular network between Arctic wireless gateways and ARM600 for establishing VPN tunnels, to mitigate security risks and avoid potential vulnerabilities. As part of ABB product lifecycle policy, once a product transitions to Limited state, we discontinue maintenance, security patches, and technical support to focus on current and future technologies. While the product will continue to function, we strongly recommend implementing mitigations defined in this document to mitigate security risks.

Affected: Alpaquita:stream: linux-lts

A use-after-free vulnerability in the Linux kernel's net/sched: cls_u32 component can be exploited to achieve local privilege escalation.

If tcf_change_indev() fails, u32_set_parms() will immediately return an error after incrementing or decrementing the reference counter in tcf_bind_filter(). If an attacker can control the reference counter and set it to zero, they can cause the reference to be freed, leading to a use-after-free vulnerability.

We recommend upgrading past commit 04c55383fa5689357bcdd2c8036725a55ed632bc.

json-c through 0.14 has an integer overflow and out-of-bounds write via a large JSON file, as demonstrated by printbuf_memappend. A memory overflow vulnerability was found in the Linux kernel’s ipc functionality of the memcg subsystem, in the way a user calls the semget function multiple times, creating semaphores. This flaw allows a local user to starve the resources, causing a denial of service. The highest threat from this vulnerability is to system availability. A vulnerability was found in the fs/inode.c:inode_init_owner() function logic of the LInux kernel that allows local users to create files for the XFS file-system with an unintended group ownership and with group execution and SGID permission bits set, in a scenario where a directory is SGID and belongs to a certain group and is writable by a user who is not a member of this group. This can lead to excessive permissions granted in case when they should not. This vulnerability is similar to the previous CVE-2018-13405 and adds the missed fix for the XFS. When sending malicous data to kernel by ioctl cmd FBIOPUT_VSCREENINFO,kernel will write memory out of bounds. In gc_data_segment in fs/f2fs/gc.c in the Linux kernel before 5.16.3, special files are not considered, leading to a move_data_page NULL pointer dereference. A flaw was found in the Linux kernel. The existing KVM SEV API has a vulnerability that allows a non-root (host) user-level application to crash the host kernel by creating a confidential guest VM inst…

Affected: openEuler:22.03-LTS-SP1: kernel

The Linux Kernel, the operating system core itself. Security Fix(es): In multiple functions of binder.c, there is a possible memory corruption due to a use after free. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation. (CVE-2023-21255) (CVE-2023-2163) A flaw was found in the Linux kernel's ksmbd, a high-performance in-kernel SMB server. The specific flaw exists within the handling of SMB2_TREE_CONNECT and SMB2_QUERY_INFO commands. The issue results from the lack of proper validation of a pointer prior to accessing it. An attacker can leverage this vulnerability to create a denial-of-service condition on the system.(CVE-2023-32248) VUL-0: CVE-2023-32255: kernel: Linux Kernel ksmbd Session Setup Memory Leak Denial-of-Service Vulnerability(CVE-2023-32255) A use-after-free flaw was found in vcs_read in drivers/tty/vt/vc_screen.c in vc_screen in the Linux Kernel. This flaw allows an attacker with local user access to cause a system crash or leak internal kernel information.(CVE-2023-3567) A use-after-free vulnerability in the Linux kernel's net/sched: cls_u32 component can be exploited to achieve local privilege escalation. If tcf_change_indev() fails, u32_set_parms() will immediately return an error after incrementing or decrementing the reference counter in tcf_bind_filter().
