Security Bulletin
This security bulletin contains information about 5 vulnerabilities.
1) Buffer overflow
EUVDB-ID: #VU69758
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-2022-3545
CWE-ID:
CWE-119 - Memory corruption
Exploit availability: No
DescriptionThe vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a boundary error within the area_cache_get() function in drivers/net/ethernet/netronome/nfp/nfpcore/nfp_cppcore.c. A local user can trigger memory corruption and execute arbitrary code with elevated privileges.
Update the affected package the Linux Kernel (Live Patch 35 for SLE 12 SP5) to the latest version.
Vulnerable software versionsSUSE Linux Enterprise Live Patching: 12-SP5

2) Use-after-free
EUVDB-ID: #VU69708
Risk: Low
CVSSv4.0: 1.1 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear]
CVE-ID: CVE-2022-3586
CWE-ID:
CWE-416 - Use After Free
Exploit availability: No
DescriptionThe vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to a use-after-free error in the way the sch_sfb enqueue function used the socket buffer (SKB) cb
field after the same SKB had been enqueued (and freed) into a child
qdisc. A local user can perform a denial of service (DoS) attack.
Update the affected package the Linux Kernel (Live Patch 35 for SLE 12 SP5) to the latest version.
