The vulnerability exists due to the way non-transparent sharing of branch predictor targets between contexts. A local user can exploit the vulnerability to gain access to sensitive information.

Mitigation

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

9) Use-after-free

EUVDB-ID: #VU64944

Risk: Low

CVSSv3.1: 2.9 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:L/E:U/RL:O/RC:C]

CVE-ID: CVE-2022-33981

CWE-ID: CWE-416 - Use After Free

Exploit availability: No

Description

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

The vulnerability exists due to a use-after-free error in drivers/block/floppy.c in the Linux kernel when deallocating raw_cmd in the raw_cmd_ioctl function(). A local user can trigger use-after-free and perform denial of service attack.

Mitigation

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

10) Type Confusion

EUVDB-ID: #VU65360

Risk: Low

CVSSv3.1: 7.5 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H/E:H/RL:O/RC:C]

CVE-ID: CVE-2022-34918

CWE-ID: CWE-843 - Type confusion

Exploit availability: Yes

Description

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

The vulnerability exists in the Linux kernel’s Netfilter subsystem in the way a user provides incorrect input of the NFT_DATA_VERDICT type. A local user can pass specially crafted data to the application, trigger a type confusion error and escalate privileges on the system.

Mitigation

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