EUVDB-ID: #VU71686
Risk: Low
CVSSv4.0: 1.7 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear]
CVE-ID: CVE-2021-4238
CWE-ID:
CWE-331 - Insufficient Entropy
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to gain access to sensitive information.
The vulnerability exists due to insufficient entropy when generating alphanumeric strings within RandomAlphaNumeric and CryptoRandomAlphaNumeric functions, which always return strings containing at least one digit from 0 to 9. A remote attacker can launch brute-force attacks and gain access to sensitive information.

CVE-ID: CVE-2022-3564
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_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.
