EUVDB-ID: #VU66811

Risk: Medium

CVSSv4.0: 1.7 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:L/VA:L/SC:N/SI:N/SA:N/E:U/U:Green]

CVE-ID: CVE-2020-36516

CWE-ID: CWE-327 - Use of a Broken or Risky Cryptographic Algorithm

Exploit availability: No

Description

The vulnerability allows a remote attacker to perform a denial of service (DoS) or MitM attacks.

The vulnerability exists due to an error in the mixed IPID assignment method with the hash-based IPID assignment policy in Linux kernel. A remote attacker can inject data into a victim's TCP session or terminate that session.

Mitigation

4) Use-after-free

EUVDB-ID: #VU63838

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-2021-4203

CWE-ID: CWE-416 - Use After Free

Exploit availability: No

Description

The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to a use-after-free error in sock_getsockopt() function in net/core/sock.c due to SO_PEERCRED and SO_PEERGROUPS race with listen() function (and connect() function) in the Linux kernel. A local user can exploit the use-after-free error and crash the system or escalate privileges on the system.

Mitigation

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

CVE-ID: CVE-2022-2588

CWE-ID: CWE-415 - Double Free

Exploit availability: Yes

Description

The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to a double free error within the network packet scheduler implementation in the route4_change() function in Linux kernel when removing all references to a route filter before freeing it. A local user can run a specially crafted program to crash the kernel or execute arbitrary code.

Mitigation

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

15) Input validation error

EUVDB-ID: #VU66476

Risk: Medium

CVSSv4.0: 7.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:P/U:Green]

CVE-ID: CVE-2022-36946

CWE-ID: CWE-20 - Improper input validation

Exploit availability: Yes

Description

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to insufficient validation of user-supplied input within the nfqnl_mangle() function in net/netfilter/nfnetlink_queue.c in the Linux kernel when processing IPv6 packets. A remote attacker can send specially crafted packets to the system and perform a denial of service (DoS) attack.

Mitigation

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