Security Bulletin
This security bulletin contains information about 2 vulnerabilities.
1) Out-of-bounds read
EUVDB-ID: #VU64702
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-2021-0941
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 in __bpf_skb_max_len() function in net/core/filter.c in the Linux kernel. A local user with special privilege can gain access to out-of-bounds memory leading to a system crash or a leak of internal kernel information.
MitigationUpdate the affected package the Linux Kernel (Live Patch 23 for SLE 15 SP1) to the latest version.

2) Use of insufficiently random values
EUVDB-ID: #VU63839
Risk: Medium
CVSSv4.0: 2.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Green]
CVE-ID: CVE-2021-20322
CWE-ID:
CWE-330 - Use of Insufficiently Random Values
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to gain access to sensitive information.
The vulnerability exists due to an error when processing received ICMP errors. A remote attacker can effectively bypass the source port UDP randomization to gain access to sensitive information.
MitigationUpdate the affected package the Linux Kernel (Live Patch 23 for SLE 15 SP1) to the latest version.
