2) Use-after-free
EUVDB-ID: #VU75994
Risk: Low
CVSSv4.0: 4.3 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear]
CVE-ID: CVE-2023-2162
CWE-ID:
CWE-416 - Use After Free
Exploit availability: No
DescriptionThe vulnerability allows a local user to gain access to sensitive information.
The vulnerability exists due to a use-after-free error within the scsi_sw_tcp_session_create() function in drivers/scsi/iscsi_tcp.c in SCSI sub-component in the Linux Kernel. A local user can trigger a use-after-free error and gain access to sensitive information.
Update the affected package the Linux Kernel (Live Patch 11 for SLE 15 SP4) to the latest version.

3) Type Confusion
EUVDB-ID: #VU71478
Risk: Low
CVSSv4.0: 4.3 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear]
CVE-ID: CVE-2023-23454
CWE-ID:
CWE-843 - Type confusion
Exploit availability: No
DescriptionThe vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to a type confusion error within the cbq_classify() function in net/sched/sch_cbq.c in the Linux kernel. A local user can trigger a type confusion error and crash the kernel.
Update the affected package the Linux Kernel (Live Patch 11 for SLE 15 SP4) to the latest version.
