Security Bulletin

This security bulletin contains information about 4 vulnerabilities.

1) Out-of-bounds read

EUVDB-ID: #VU80795

Risk: Low

CVSSv4.0: 1.7 [CVSS:4.0/AV:P/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2023-37453

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

Exploit availability: No

Description

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

The vulnerability exists due to a boundary condition within the read_descriptors() function in drivers/usb/core/sysfs.c. An attacker with physical access to the system can attach a malicious USB device, trigger an out-of-bounds read error and crash the kernel.

Mitigation

Install updates from vendor's repository.

Q & A

Can this vulnerability be exploited remotely?

No. The attacker should have physical access to the system in order to successfully exploit this vulnerability.

Is there known malware, which exploits this vulnerability?

No. We are not aware of malware exploiting this vulnerability.

2) Improper access control

EUVDB-ID: #VU82764

Risk: Low

CVSSv4.0: 7 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N/E:P/U:Clear]

CVE-ID: CVE-2023-46813

CWE-ID: CWE-284 - Improper Access Control

Exploit availability: Yes

Description

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

The vulnerability exists due to improper access checking in the #VC handler and instruction emulation of the SEV-ES emulation of MMIO accesses. A local user can gain arbitrary write access to kernel memory and execute arbitrary code with elevated privileges.

Mitigation

Install updates from vendor's repository.

3) NULL pointer dereference

EUVDB-ID: #VU83903

Risk: Low

CVSSv4.0: 4.3 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2023-46862

CWE-ID: CWE-476 - NULL Pointer Dereference

Exploit availability: No

Description

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

The vulnerability exists due to a NULL pointer dereference error within the io_uring_show_fdinfo() function in io_uring/fdinfo.c. A local user can trigger a race with SQ thread exit and perform a denial of service (DoS) attack.

Mitigation

Install updates from vendor's repository.

4) Use-after-free

EUVDB-ID: #VU82658

Risk: Low

CVSSv4.0: 7.1 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:P/U:Clear]

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.

Mitigation

Install updates from vendor's repository.
