Security Bulletin
This security bulletin contains information about 2 vulnerabilities.
1) Out-of-bounds read
EUVDB-ID: #VU82659
Risk: Low
CVSSv4.0: 5.7 [CVSS:4.0/AV:L/AC:L/AT:N/PR:H/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear]
CVE-ID: CVE-2023-39189
CWE-ID:
CWE-125 - Out-of-bounds read
Exploit availability: No
DescriptionThe vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a boundary condition within the nfnl_osf_add_callback() function in Linux kernel Netfilter. A local user with CAP_NET_ADMIN capability can trigger an out-of-bounds read error and execute arbitrary code with elevated privileges.
Install updates from vendor's repository.

2) Out-of-bounds read
EUVDB-ID: #VU81920
Risk: Low
CVSSv4.0: 1 [CVSS:4.0/AV:L/AC:L/AT:N/PR:H/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear]
CVE-ID: CVE-2023-39193
CWE-ID:
CWE-125 - Out-of-bounds read
Exploit availability: No
DescriptionThe vulnerability allows a local user to gain access to potentially sensitive information.
The vulnerability exists due to a boundary condition within the sctp_mt_check() function in Netfilter subsystem in Linux kernel. A local user with CAP_NET_ADMIN capability can trigger an out-of-bounds read error and read contents of memory on the system.
