4) NULL pointer dereference

EUVDB-ID: #VU62483

Risk: Low

CVSSv4.0: 4.3 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2021-44879

CWE-ID: CWE-476 - NULL Pointer Dereference

Exploit availability: No

Description

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

CVE-ID: CVE-2022-0494

CWE-ID: CWE-200 - Information exposure

Exploit availability: No

Description

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

The vulnerability exists due to excessive data output in the scsi_ioctl() function in drivers/scsi/scsi_ioctl.c in the Linux kernel. A local user with a special user privilege (CAP_SYS_ADMIN or CAP_SYS_RAWIO) can gain unauthorized access to sensitive information on the system.

Mitigation

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

EUVDB-ID: #VU64263

Risk: Low

CVSSv4.0: 5.7 [CVSS:4.0/AV:L/AC:L/AT:N/PR:H/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2022-1974

CWE-ID: CWE-416 - Use After Free

Exploit availability: No

Description

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

The vulnerability exists due to a use-after-free error in the Linux kernel's NFC core functionality due to a race condition between kobject creation and delete. A local attacker with CAP_NET_ADMIN privilege can leak kernel information and escalate privileges on the system.

Mitigation

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

CVE-ID: CVE-2022-26365

CWE-ID: CWE-200 - Information exposure

Exploit availability: No

Description

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

The vulnerability exists due to Linux Block and Network PV device frontends don't zero memory regions before sharing them with the backend. A local user can gain unauthorized access to sensitive information on the system.

Mitigation

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

EUVDB-ID: #VU65351

Risk: Low

CVSSv4.0: 4.3 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2022-33741

CWE-ID: CWE-200 - Information exposure

Exploit availability: No

Description

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

The vulnerability exists due to granularity of the grant table doesn't allow sharing less than a 4K page, leading to unrelated data residing in the same 4K page as data shared with a backend being accessible by such backend. A local user can gain unauthorized access to sensitive information on the system.

Mitigation

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