SB2024122050 - openEuler 22.03 LTS SP3 update for kernel

Description

This security bulletin contains information about 8 secuirty vulnerabilities.

1) NULL pointer dereference (CVE-ID: CVE-2022-48868)

The vulnerability allows a local user to perform a denial of service (DoS) attack.

The vulnerability exists due to NULL pointer dereference within the __drv_enable_wq() function in drivers/dma/idxd/device.c. A local user can perform a denial of service (DoS) attack.

2) Buffer overflow (CVE-ID: CVE-2023-52434)

The vulnerability allows a remote user to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error within the smb2_parse_contexts() function when parsing SMB packets. A remote user can send specially crafted SMB traffic to the affected system, trigger memory corruption and execute arbitrary code.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.

3) NULL pointer dereference (CVE-ID: CVE-2023-6356)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to a NULL pointer dereference error within the nvmet_tcp_build_iovec() function in the Linux kernel's NVMe driver. A remote attacker can pass specially crafted TCP packets to the system and perform a denial of service (DoS) attack.

4) NULL pointer dereference (CVE-ID: CVE-2023-6535)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to a NULL pointer dereference error within the nvmet_tcp_execute_request() function in the Linux kernel's NVMe driver. A remote attacker can send specially crafted NVMe-oF/TCP packets to the system and perform a denial of service (DoS) attack.

5) NULL pointer dereference (CVE-ID: CVE-2023-6536)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to a NULL pointer dereference error within the __nvmet_req_complete() function in the Linux kernel's NVMe driver. A remote attacker can send specially crafted NVMe-oF/TCP packets to the system and perform a denial of service (DoS) attack.

6) Input validation error (CVE-ID: CVE-2024-50218)

The vulnerability allows a local user to perform a denial of service (DoS) attack.

The vulnerability exists due to improper input validation within the ocfs2_remove_inode_range() function in fs/ocfs2/file.c. A local user can perform a denial of service (DoS) attack.

7) Input validation error (CVE-ID: CVE-2024-53114)

The vulnerability allows a local user to perform a denial of service (DoS) attack.

The vulnerability exists due to improper input validation within the init_amd_zen4() function in arch/x86/kernel/cpu/amd.c. A local user can perform a denial of service (DoS) attack.

8) Use of uninitialized resource (CVE-ID: CVE-2024-53142)

The vulnerability allows a local user to perform a denial of service (DoS) attack.

The vulnerability exists due to use of uninitialized resource within the do_name() and do_copy() functions in init/initramfs.c. A local user can perform a denial of service (DoS) attack.
