2) Use-after-free
EUVDB-ID: #VU81693
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-2023-4921
CWE-ID:
CWE-416 - Use After Free
Exploit availability: No
DescriptionThe vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a use-after-free error in the qfq_dequeue() function within the the Linux kernel's net/sched: sch_qfq component. A local user can trigger a use-after-free error and execute arbitrary code with elevated privileges.
Update the affected package the Linux Kernel RT (Live Patch 3 for SLE 15 SP5) to the latest version.
