Security Bulletin

This security bulletin contains information about 10 vulnerabilities.

1) Improper access control

EUVDB-ID: #VU53578

Risk: Low

CVSSv3.1: 3.8 [CVSS:3.1/AV:P/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L/E:U/RL:O/RC:C]

CVE-ID: CVE-2020-26555

CWE-ID: CWE-284 - Improper Access Control

Exploit availability: No

Description

The vulnerability allows a local attacker to gain unauthorized access to otherwise restricted functionality.

The vulnerability exists due to improper access restrictions within the Bluetooth legacy BR/EDR PIN code pairing. An attacker with physical access can spoof the BD_ADDR of the peer device and complete pairing without knowledge of the PIN.

Mitigation

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

CVE-ID: CVE-2023-6531

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 when the unix garbage collector's deletion of a SKB races with unix_stream_read_generic() on the socket that the SKB is queued on. A local user can exploit the race and escalate privileges on the system.

7) Out-of-bounds read

EUVDB-ID: #VU85443

Risk: Low

CVSSv3.1: 6.2 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2023-6610

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

Exploit availability: No

Description

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

The vulnerability exists due to a boundary condition within the smb2_dump_detail() function in fs/smb/client/smb2ops.c. A local user can trigger an out-of-bounds read error and gain access to sensitive information or crash the kernel.

Mitigation

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