Security Bulletin
This security bulletin contains information about 6 vulnerabilities.
1) Cryptographic Issues
EUVDB-ID: #VU109316
Risk: Medium
CVSSv4.0: 2.3 [CVSS:4.0/AV:A/AC:L/AT:N/PR:N/UI:N/VC:N/VI:L/VA:N/SC:H/SI:L/SA:N/E:U/U:Green]
CVE-ID: CVE-2020-3702
CWE-ID:
CWE-310 - Cryptographic Issues
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to gain access top sensitive information.
The vulnerability exists due to improper input validation in WIFI driver(Krook). A remote attacker can temporary disable WPA2 or the WPA/WPA2 mixed-mode encryption and intercept traffic in clear text.
MitigationUpdate the affected package the Linux Kernel to the latest version.

No. We are not aware of malware exploiting this vulnerability.
2) Resource exhaustion
EUVDB-ID: #VU63911
Risk: Low
CVSSv4.0: 4.3 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear]
CVE-ID: CVE-2021-3669
CWE-ID:
CWE-400 - Resource exhaustion
Exploit availability: No
DescriptionThe vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to measuring usage of the shared memory does not scale with large shared memory segment counts. A local user can trigger resource exhaustion and perform a denial of service (DoS) attack.
MitigationUpdate the affected package the Linux Kernel to the latest version.

3) Memory leak
EUVDB-ID: #VU63813
Risk: Low
CVSSv4.0: 4.3 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear]
CVE-ID: CVE-2021-3744
CWE-ID:
CWE-401 - Missing release of memory after effective lifetime
Exploit availability: No
DescriptionThe vulnerability allows a local user to perform DoS attack on the target system.
The vulnerability exists due memory leak in the ccp_run_aes_gcm_cmd() function in drivers/crypto/ccp/ccp-ops.c. A local user can force the application to leak memory and perform denial of service attack.
MitigationUpdate the affected package the Linux Kernel to the latest version.

CVSSv4.0: 4.8 [CVSS:4.0/AV:A/AC:L/AT:P/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear]
CVE-ID: CVE-2021-3752
CWE-ID:
CWE-416 - Use After Free
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to escalate privileges on the system.
The vulnerability exists due to a use-after-free error in the Linux kernel’s Bluetooth subsystem when a user calls connect to the socket and disconnect simultaneously. A local user can escalate privileges on the system.
MitigationUpdate the affected package the Linux Kernel to the latest version.

6) Race condition
EUVDB-ID: #VU63667
Risk: Low
CVSSv4.0: 5.9 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear]
CVE-ID: CVE-2021-40490
Exploit availability: No
DescriptionThe vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a race condition in ext4_write_inline_data_end in fs/ext4/inline.c in the ext4 subsystem in the Linux kernel. A local user can exploit the race and gain unauthorized access to sensitive information and escalate privileges on the system.
MitigationUpdate the affected package the Linux Kernel to the latest version.
