Security Bulletin

This security bulletin contains information about 4 vulnerabilities.

1) Missing initialization of resource

EUVDB-ID: #VU61098

Risk: Medium

CVSSv4.0: 2.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Green]

CVE-ID: CVE-2021-3655

CWE-ID: CWE-909 - Missing initialization of resource

Exploit availability: No

Description

The vulnerability allows a remote attacker to gain access to sensitive information.

The vulnerability exists due to missing initialization of resource in the Linux kernel when processing inbound SCTP packets. A remote attacker can send specially crafted SCTP packets to the system and force the kernel to read uninitialized memory.

Mitigation

Update the affected package linux to the latest version.

2) Double Free

EUVDB-ID: #VU63575

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-2021-37159

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 hso_free_net_device() function in drivers/net/usb/hso.c in the Linux kernel calls unregister_netdev without checking for the NETREG_REGISTERED state. A local user can trigger double free and use-after-free errors and execute arbitrary code with elevated privileges.

Mitigation

Update the affected package linux 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

Description

The 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.

Mitigation

Update the affected package linux to the latest version.
