CVE-ID: CVE-2022-1882

CWE-ID: CWE-416 - Use After Free

Exploit availability: No

Description

The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to a use-after-free error within the Linux kernel’s pipes functionality in free_pipe_info() function in fs/pipe.c. A local user can trigger a use-after-free error and execute arbitrary code with elevated privileges.

Mitigation

Update the affected package the Linux Kernel to the latest version.

13) Memory leak

EUVDB-ID: #VU69791

Risk: Low

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

CVE-ID: CVE-2022-3535

CWE-ID: CWE-401 - Missing release of memory after effective lifetime

Exploit availability: No

Description

The vulnerability allows a local user to perform DoS attack.

The vulnerability exists due memory leak within the mvpp2_dbgfs_port_init() function in drivers/net/ethernet/marvell/mvpp2/mvpp2_debugfs.c, when a device is probed. A local user can force the system to leak memory and perform denial of service attack.

Mitigation

Update the affected package the Linux Kernel to the latest version.

CVE-ID: CVE-2022-3586

CWE-ID: CWE-416 - Use After Free

Exploit availability: No

Description

The vulnerability allows a local user to perform a denial of service (DoS) attack.

30) Improper access control

EUVDB-ID: #VU67587

Risk: Low

CVSSv3.1: 4.8 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2022-40768

CWE-ID: CWE-284 - Improper Access Control

Exploit availability: No

Description

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

The vulnerability exists due to improper access restrictions in the drivers/scsi/stex.c in the Linux kernel. A local user can obtain sensitive information from kernel memory because stex_queuecommand_lck lacks a memset for the PASSTHRU_CMD case.

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 to the latest version.
