7) Double Free

EUVDB-ID: #VU69805

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-2022-4095

CWE-ID: CWE-415 - Double Free

Exploit availability: No

Description

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

The vulnerability exists due to a boundary error within the cmd_hdl_filter() function in drivers/staging/rtl8712/rtl8712_cmd.c. A local user can trigger a double free error and execute arbitrary code with escalated privileges.


Mitigation

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

13) Use-after-free

EUVDB-ID: #VU69795

Risk: Low

CVSSv3.1: 5.9 [CVSS:3.1/AV:P/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2022-42896

CWE-ID: CWE-416 - Use After Free

Exploit availability: No

Description

The vulnerability allows an attacker to compromise vulnerable system.

The vulnerability exists due to a use-after-free error within the l2cap_connect() and l2cap_le_connect_req() function in net/bluetooth/l2cap_core.c. An attacker with physical proximity to the affected device can trigger a use-after-free error and execute arbitrary code on the system.


Mitigation

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

15) Buffer overflow

EUVDB-ID: #VU69766

Risk: Medium

CVSSv3.1: 6.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2022-43945

CWE-ID: CWE-119 - Memory corruption

Exploit availability: No

Description

The vulnerability allows a remote attacker to perform a denial of service attacl.

The vulnerability exists due to a boundary error within the Linux kernel NFSD implementation. A remote attacker can send the RPC message over TCP with garbage data added at the end of the message, trigger memory corruption and perform a denial of service (DoS) attack.

Mitigation

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

16) Integer overflow

EUVDB-ID: #VU70464

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-2022-45934

CWE-ID: CWE-190 - Integer overflow

Exploit availability: No

Description

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

The vulnerability exists due to integer overflow within the l2cap_config_req() function in net/bluetooth/l2cap_core.c in Linux kernel. A local user can pass specially crafted L2CAP_CONF_REQ packets to the device, trigger an integer overflow and execute arbitrary code with elevated privileges.

Mitigation

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