Security Bulletin
This security bulletin contains information about 4 vulnerabilities.
EUVDB-ID: #VU78007
Risk: Low
CVSSv3.1: 6.8 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2023-3390
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 within net/netfilter/nf_tables_api.c in the Linux kernel netfilter subsystem. A local user can trigger a use-after-fee error and escalate privileges on the system.
Update the affected package the Linux Kernel RT (Live Patch 3 for SLE 15 SP4) to the latest version.

EUVDB-ID: #VU79498
Risk: Low
CVSSv3.1: 7.7 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2023-4004
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 way a user triggers the nft_pipapo_remove function with the element, without a NFT_SET_EXT_KEY_END. A local user can execute arbitrary code with elevated privileges.
Update the affected package the Linux Kernel RT (Live Patch 3 for SLE 15 SP4) to the latest version.
