Security Bulletin

This security bulletin contains information about 3 vulnerabilities.

1) Use-after-free

EUVDB-ID: #VU76410

Risk: Low

CVSSv3.1: 4.8 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2023-33288

CWE-ID: CWE-416 - Use After Free

Exploit availability: No

Description

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

The vulnerability exists due to a use-after-free error within the bq24190_remove function in drivers/power/supply/bq24190_charger.c. A local authenticated user can trigger a use-after-free error and perform a denial of service (DoS) attack.

Mitigation

Install updates from vendor's repository.

2) Use-after-free

EUVDB-ID: #VU77495

Risk: Low

CVSSv3.1: 4.8 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2023-2985

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.

The vulnerability exists due to a use-after-free error within the hfsplus_put_super() function in fs/hfsplus/super.c. A local user can trigger a use-after-free error and crash the kernel.


Mitigation

Install updates from vendor's repository.

3) Out-of-bounds read

EUVDB-ID: #VU78725

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-2022-48502

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 ntfs_set_ea() function in fs/ntfs3/xattr.c in Linux kernel ntfs3 subsystem. A local user can trigger an out-of-bounds read error and read contents of memory on the system or crash the OS kernel.

Mitigation

Install updates from vendor's repository.
