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 •

valid.c in libxml2 before 2.9.13 has a use-after-free of ID and IDREF attributes. El archivo valid.c en libxml2 versiones anteriores a 2.9.13, presenta un uso de memoria previamente liberada de los atributos ID e IDREF. A flaw was found in libxml2. A call to the xmlGetID function can return a pointer already freed when parsing an XML document with the XML_PARSE_DTDVALID option and without the XML_PARSE_NOENT option, resulting in a use-after-free issue. • http://seclists.org/fulldisclosure/2022/May/33 http://seclists.org/fulldisclosure/2022/May/34 http://seclists.org/fulldisclosure/2022/May/35 http://seclists.org/fulldisclosure/2022/May/36 http://seclists.org/fulldisclosure/2022/May/37 http://seclists.org/fulldisclosure/2022/May/38 https://github.com/GNOME/libxml2/commit/652dd12a858989b14eed4e84e453059cd3ba340e https://gitlab.gnome.org/GNOME/libxml2/-/blob/v2.9.13/NEWS https://lists.debian.org/debian-lts-announce/2022/04/msg00004. • CWE-416: Use After Free •

A flaw use after free in the Linux kernel Management Component Transport Protocol (MCTP) subsystem was found in the way user triggers cancel_work_sync after the unregister_netdev during removing device. A local user could use this flaw to crash the system or escalate their privileges on the system. It is actual from Linux Kernel 5.17-rc1 (when mctp-serial.c introduced) till 5.17-rc5. Se encontró un fallo de uso de memoria previamente liberada en el subsistema del kernel de Linux Management Component Transport Protocol (MCTP) en la forma en que el usuario desencadena cancel_work_sync después de unregister_netdev durante la eliminación del dispositivo. Un usuario local podría usar este fallo para bloquear el sistema o escalar sus privilegios en el sistema. • https://lore.kernel.org/all/20220211011552.1861886-1-jk%40codeconstruct.com.au https://security.netapp.com/advisory/ntap-20220318-0006 • CWE-416: Use After Free CWE-459: Incomplete Cleanup •

In the Linux kernel through 5.16.10, certain binary files may have the exec-all attribute if they were built in approximately 2003 (e.g., with GCC 3.2.2 and Linux kernel 2.4.20). This can cause execution of bytes located in supposedly non-executable regions of a file. En el kernel de Linux versiones hasta 5.16.10, determinados archivos binarios pueden tener el atributo exec-all si fueron construidos aproximadamente en 2003 (por ejemplo, con GCC versión 3.2.2 y el kernel de Linux versión 2.4.20).
