Security Bulletin
This security bulletin contains information about 2 vulnerabilities.
1) Out-of-bounds write
EUVDB-ID: #VU74054
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-2023-1078
CWE-ID:
CWE-787 - Out-of-bounds write
Exploit availability: No
Description The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a boundary error within the rds_rm_zerocopy_callback() function in Linux kernel RDS (Reliable Datagram Sockets) protocol. A local user can trigger an out-of-bounds write and execute arbitrary code with elevated privileges.
Update the affected package the Linux Kernel (Live Patch 8 for SLE 15 SP4) to the latest version.

2) Double Free
EUVDB-ID: #VU73766
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-2023-26545
CWE-ID:
CWE-415 - Double Free
Exploit availability: No
DescriptionThe vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a double free in net/mpls/af_mpls.c during the renaming of a device. A local user can trigger a double free error and execute arbitrary code with elevated privileges.
Update the affected package the Linux Kernel (Live Patch 8 for SLE 15 SP4) to the latest version.
