Security Bulletin
This security bulletin contains information about 5 vulnerabilities.
1) Permissions, Privileges, and Access Controls
EUVDB-ID: #VU68110
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-2022-39189
CWE-ID:
CWE-264 - Permissions, Privileges, and Access Controls
Exploit availability: No
DescriptionThe vulnerability allows a guest user to escalate privileges on the system.
The vulnerability exists due to incorrect handling of TLB flush operations in certain KVM_VCPU_PREEMPTED situations in the x86 KVM subsystem in the Linux kernel. An attacker with unprivileged access to the guest OS can escalate privileges on the guest.
Update the affected package the Linux Kernel (Live Patch 1 for SLE 15 SP4) to the latest version.

2) Buffer overflow
EUVDB-ID: #VU68311
Risk: High
CVSSv4.0: 6.3 [CVSS:4.0/AV:A/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber]
CVE-ID: CVE-2022-41674
CWE-ID:
CWE-119 - Memory corruption
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error when processing WLAN frames within the ieee80211_bss_info_update() function in net/mac80211/scan.c in Linux kernel. A remote attacker on the local network can send specially crafted WLAN frames to the affected system, trigger memory corruption and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
MitigationUpdate the affected package the Linux Kernel (Live Patch 1 for SLE 15 SP4) to the latest version.
