SUSE update for the Linux Kernel

1) Out-of-bounds write

EUVDB-ID: #VU79673

Risk: Low

CVSSv3.1: 7.7 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2023-2163

CWE-ID: CWE-787 - Out-of-bounds write

Exploit availability: No

Description

The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to a boundary error in BPF verifier caused by improper marking of registers for precision tracking in certain situations. A local user can trigger an out-of-bounds write and execute arbitrary code with elevated privileges.

Mitigation

Update the affected package the Linux Kernel to the latest version.

2) Out-of-bounds read

EUVDB-ID: #VU78675

Risk: Low

CVSSv3.1: 2 [CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:L/I:N/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2023-2860

CWE-ID: CWE-125 - Out-of-bounds read

Exploit availability: No

Description

The vulnerability allows a local user to gain access to potentially sensitive information.

The vulnerability exists due to a boundary condition within the SR-IPv6 implementation when processing seg6 attributes. A local user can trigger an out-of-bounds read error and read contents of memory on the system.

Mitigation

Update the affected package the Linux Kernel to the latest version.

5) Out-of-bounds read

EUVDB-ID: #VU82659

Risk: Low

CVSSv3.1: 5.8 [CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2023-39189

CWE-ID: CWE-125 - Out-of-bounds read

Exploit availability: No

Description

The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to a boundary condition within the nfnl_osf_add_callback() function in Linux kernel Netfilter. A local user with CAP_NET_ADMIN capability can trigger an out-of-bounds read error and execute arbitrary code with elevated privileges.

Mitigation

Update the affected package the Linux Kernel to the latest version.

7) Out-of-bounds read

EUVDB-ID: #VU81920

Risk: Low

CVSSv3.1: 2 [CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:L/I:N/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2023-39193

CWE-ID: CWE-125 - Out-of-bounds read

Exploit availability: No

Description

The vulnerability allows a local user to gain access to potentially sensitive information.

The vulnerability exists due to a boundary condition within the sctp_mt_check() function in Netfilter subsystem in Linux kernel. A local user with CAP_NET_ADMIN capability can trigger an out-of-bounds read error and read contents of memory on the system.

9) Use-after-free

EUVDB-ID: #VU82658

Risk: Low

CVSSv3.1: 7 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H/E:P/RL:O/RC:C]

CVE-ID: CVE-2023-5178

CWE-ID: CWE-416 - Use After Free

Exploit availability: Yes

Description

The vulnerability allows a local authenticated user to escalate privileges on the system.

The vulnerability exists due to a use-after-free error within the drivers/nvme/target/tcp.c in nvmet_tcp_free_crypto due to a logical bug in the NVMe-oF/TCP subsystem in the Linux kernel. A local authenticated user can trigger a use-after-free error and escalate privileges on the system.
