CVSS: 5.9EPSS: 0%CPEs: 29EXPL: 0CVE-2020-36516 – kernel: off-path attacker may inject data or terminate victim's TCP session
https://notcve.org/view.php?id=CVE-2020-36516
An issue was discovered in the Linux kernel through 5.16.11. The mixed IPID assignment method with the hash-based IPID assignment policy allows an off-path attacker to inject data into a victim's TCP session or terminate that session. Se ha detectado un problema en el kernel de Linux versiones hasta 5.16.11. El método de asignación de IPID mixto con la política de asignación de IPID basada en hash permite a un atacante fuera de la ruta inyectar datos en la sesión TCP de una víctima o terminar esa sesión. A TCP/IP packet spoofing attack flaw was found in the Linux kernel’s TCP/IP protocol, where a Man-in-the-Middle Attack (MITM) performs an IP fragmentation attack and an IPID collision. • https://dl.acm.org/doi/10.1145/3372297.3417884 https://security.netapp.com/advisory/ntap-20220331-0003 https://access.redhat.com/security/cve/CVE-2020-36516 https://bugzilla.redhat.com/show_bug.cgi?id=2059928 • CWE-290: Authentication Bypass by Spoofing CWE-327: Use of a Broken or Risky Cryptographic Algorithm •
CVSS: 9.0EPSS: 0%CPEs: 60EXPL: 2CVE-2022-0435 – kernel: remote stack overflow via kernel panic on systems using TIPC may lead to DoS
https://notcve.org/view.php?id=CVE-2022-0435
A stack overflow flaw was found in the Linux kernel's TIPC protocol functionality in the way a user sends a packet with malicious content where the number of domain member nodes is higher than the 64 allowed. This flaw allows a remote user to crash the system or possibly escalate their privileges if they have access to the TIPC network. Se ha encontrado un fallo de desbordamiento de pila en la funcionalidad del protocolo TIPC del kernel de Linux en la forma en que un usuario envía un paquete con contenido malicioso cuando el número de nodos miembros del dominio es superior a los 64 permitidos.
