7) Use-after-free

EUVDB-ID: #VU75204

Risk: Low

CVSSv3.1: 4.1 [CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2023-1611

CWE-ID: CWE-416 - Use After Free

Exploit availability: No

Description

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

13) Double Free

EUVDB-ID: #VU74147

Risk: Low

CVSSv3.1: 6.8 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2023-28464

CWE-ID: CWE-415 - Double Free

Exploit availability: No

Description

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

The vulnerability exists due to a boundary error within the hci_conn_cleanup() function in net/bluetooth/hci_conn.c in Linux kernel. A local user can trigger a double free error and execute arbitrary code with elevated privileges.

Mitigation

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

14) Race condition

EUVDB-ID: #VU74628

Risk: Low

CVSSv3.1: 6.1 [CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2023-28466

CWE-ID: CWE-362 - Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition')

Exploit availability: No

Description

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

The vulnerability exists due to a race condition caused by a missing lock_sock call within the do_tls_getsockopt() function in net/tls/tls_main.c. A local user can exploit the race and gain unauthorized access to sensitive information and escalate privileges on the system.

Mitigation

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