3) Use-after-free

EUVDB-ID: #VU69799

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-2022-3564

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_reassemble_sdu() function in net/bluetooth/l2cap_core.c. An attacker with physical access to device can trigger a use-after-free error and execute arbitrary code on the system.

Mitigation

4) Out-of-bounds read

EUVDB-ID: #VU70627

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-2022-47520

CWE-ID: CWE-125 - Out-of-bounds read

Exploit availability: No

Description

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

The vulnerability exists due to a boundary condition within the drivers/net/wireless/microchip/wilc1000/hif.c in the WILC1000 wireless driver. A local user can trigger an out-of-bounds read when parsing a Robust Security Network (RSN) information element from a Netlink packet and perform a denial of service (DoS) attack.

Mitigation

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