Security Bulletin

This security bulletin contains information about 17 vulnerabilities.

1) Use-after-free

EUVDB-ID: #VU68423

Risk: Low

CVSSv3.1: 6.3 [CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H/E:P/RL:O/RC:C]

CVE-ID: CVE-2022-2602

CWE-ID: CWE-416 - Use After Free

Exploit availability: Yes

Description

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

The vulnerability exists due to a use-after-free error caused by an io_uring request, which is being processed on a registered file. The Unix GC runs and frees the io_uring file descriptor and all the registered file descriptors in a specific order that may allow a local user to win a race and execute arbitrary code with elevated privileges.

Mitigation

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

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.

9) NULL pointer dereference

EUVDB-ID: #VU70486

Risk: Low

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

CVE-ID: CVE-2022-4129

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.

The vulnerability exists due to a NULL pointer dereference error in the Linux kernel's Layer 2 Tunneling Protocol (L2TP). A missing lock when clearing sk_user_data can lead to a race condition and NULL pointer dereference. A local user could use this flaw to potentially crash the system causing a denial of service.

Mitigation

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

16) 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.

17) 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.
