No. This vulnerability can be exploited locally. The attacker should have authentication credentials and successfully authenticate on the system.
Is there known malware, which exploits this vulnerability?
No. We are not aware of malware exploiting this vulnerability.
2) Race condition
EUVDB-ID: #VU85022
Risk: Low
CVSSv4.0: 5.9 [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:U/U:Clear]
CVE-ID: CVE-2023-6531
Exploit availability: No
DescriptionThe 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.
MitigationUpdate the affected package the Linux Kernel (Live Patch 21 for SLE 15 SP4) to the latest version.
