EUVDB-ID: #VU72699
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-2023-1077
CWE-ID:
CWE-843 - Type confusion
Exploit availability: No
DescriptionThe vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a type confusion error within the pick_next_rt_entity() function pick_next_rt_entity(). A local user can trigger a type confusion error and execute arbitrary code with elevated privileges.
Update the affected package the Linux Kernel (Live Patch 37 for SLE 15 SP1) to the latest version.

2) Out-of-bounds read
EUVDB-ID: #VU75995
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-2023-2176
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 compare_netdev_and_ip() function in drivers/infiniband/core/cma.c in RDMA in the Linux Kernel. A local user can trigger an out-of-bounds read error and read contents of memory on the system.
MitigationUpdate the affected package the Linux Kernel (Live Patch 37 for SLE 15 SP1) to the latest version.
