SUSE update for the Linux Kernel (Live Patch 29 for SLE 15 SP2)

1) Permissions, Privileges, and Access Controls

EUVDB-ID: #VU68110

Risk: Low

CVSSv3.1: 6.8 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2022-39189

CWE-ID: CWE-264 - Permissions, Privileges, and Access Controls

Exploit availability: No

Description

The 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.

Mitigation

Update the affected package the Linux Kernel (Live Patch 29 for SLE 15 SP2) to the latest version.

2) Use-after-free

EUVDB-ID: #VU68422

Risk: Low

CVSSv3.1: 2.2 [CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:L/I:N/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2022-41222

CWE-ID: CWE-416 - Use After Free

Exploit availability: No

Description

The vulnerability allows a local user to gain access to sensitive information.

The vulnerability exists due to a use-after-free error caused by a stale TLB in mm/mremap.c, because an rmap lock is not held during a PUD move. A local user can gain access to sensitive information.

Mitigation

Update the affected package the Linux Kernel (Live Patch 29 for SLE 15 SP2) to the latest version.

3) Buffer overflow

EUVDB-ID: #VU68311

Risk: High

CVSSv3.1: 7.7 [CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2022-41674

CWE-ID: CWE-119 - Memory corruption

Exploit availability: No

Description

The 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.

Mitigation

Update the affected package the Linux Kernel (Live Patch 29 for SLE 15 SP2) to the latest version.

4) Use-after-free

EUVDB-ID: #VU68313

Risk: High

CVSSv3.1: 7.7 [CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2022-42719

CWE-ID: CWE-416 - Use After Free

Exploit availability: No

Description

The vulnerability allows a remote attacker to compromise vulnerable system.

The vulnerability exists due to a use-after-free error in the mac80211 stack in Linux kernel when parsing a multi-BSSID element. A remote attacker on the local network can send specially crafted WLAN frames to the affected system, trigger a use-after-free error and execute arbitrary code.

Mitigation

Update the affected package the Linux Kernel (Live Patch 29 for SLE 15 SP2) to the latest version.

6) Buffer overflow

EUVDB-ID: #VU68316

Risk: High

CVSSv3.1: 7.7 [CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2022-42721

CWE-ID: CWE-119 - Memory corruption

Exploit availability: No

Description

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a list management error in the mac80211 stack in the Linux kernel when handling BSS. A remote attacker on the local network can send specially crafted WLAN frames to the system, trigger linked list corruption and execute arbitrary code.

Mitigation

Update the affected package the Linux Kernel (Live Patch 29 for SLE 15 SP2) to the latest version.
