Multiple vulnerabilities in IBM Spectrum Copy Data Management

1) Use-after-free

EUVDB-ID: #VU62358

Risk: Low

CVSSv3.1: 5.3 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2022-1280

CWE-ID: CWE-416 - Use After Free

Exploit availability: No

Description

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

The vulnerability exists due to a use-after-free error within the drm_lease_held() function in drivers/gpu/drm/drm_lease.c in the Linux kernel. A local user can run a specially crafted program to trigger a use-after-free error and crash the kernel or gain access to sensitive information.

Mitigation

Install update from vendor's website.
