Security Bulletin
This security bulletin contains information about 2 vulnerabilities.
1) Access of Uninitialized Pointer
EUVDB-ID: #VU69796
Risk: Low
CVSSv4.0: 0.4 [CVSS:4.0/AV:P/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear]
CVE-ID: CVE-2022-42895
CWE-ID:
CWE-824 - Access of Uninitialized Pointer
Exploit availability: No
DescriptionThe vulnerability allows an attacker to gain access to sensitive information.
The vulnerability exists due to unauthorized access of uninitialized pointer within the l2cap_parse_conf_req() function in net/bluetooth/l2cap_core.c. An attacker with physical proximity to the affected device can gain access to sensitive information.
Install updates from vendor's repository.

2) Use-after-free
EUVDB-ID: #VU69795
Risk: Low
CVSSv4.0: 4 [CVSS:4.0/AV:P/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear]
CVE-ID: CVE-2022-42896
CWE-ID:
CWE-416 - Use After Free
Exploit availability: No
DescriptionThe 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
