https://notcve.org/view.php?id=CVE-2022-1263
A NULL pointer dereference issue was found in KVM when releasing a vCPU with dirty ring support enabled. This flaw allows an unprivileged local attacker on the host to issue specific ioctl calls, causing a kernel oops condition that results in a denial of service. Se encontró un problema de desreferencia de puntero NULL en KVM cuando es liberada una vCPU con el soporte de anillo sucio habilitado. Este fallo permite a un atacante local no privilegiado en el host emitir llamadas ioctl específicas, causando una condición de oops en el kernel que resulta en una denegación de servicio • https://access.redhat.com/security/cve/CVE-2022-1263 https://bugzilla.redhat.com/show_bug.cgi?id=2072698 https://github.com/torvalds/linux/commit/5593473a1e6c743764b08e3b6071cb43b5cfa6c4 https://www.openwall.com/lists/oss-security/2022/04/07/1 • CWE-476: NULL Pointer Dereference •
CVSS: 7.8EPSS: 0%CPEs: 14EXPL: 1CVE-2022-1708 – cri-o: memory exhaustion on the node when access to the kube api
https://notcve.org/view.php?id=CVE-2022-1708
A vulnerability was found in CRI-O that causes memory or disk space exhaustion on the node for anyone with access to the Kube API. The ExecSync request runs commands in a container and logs the output of the command. This output is then read by CRI-O after command execution, and it is read in a manner where the entire file corresponding to the output of the command is read in. Thus, if the output of the command is large it is possible to exhaust the memory or the disk space of the node when CRI-O reads the output of the command. The highest threat from this vulnerability is system availability. • https://bugzilla.redhat.com/show_bug.cgi?id=2085361 https://github.com/cri-o/cri-o/commit/f032cf649ecc7e0c46718bd9e7814bfb317cb544 https://github.com/cri-o/cri-o/security/advisories/GHSA-fcm2-6c3h-pg6j https://access.redhat.com/security/cve/CVE-2022-1708 • CWE-400: Uncontrolled Resource Consumption CWE-770: Allocation of Resources Without Limits or Throttling •

An access control bypass vulnerability found in 389-ds-base. That mishandling of the filter that would yield incorrect results, but as that has progressed, can be determined that it actually is an access control bypass. This may allow any remote unauthenticated user to issue a filter that allows searching for database items they do not have access to, including but not limited to potentially userPassword hashes and other sensitive data. Una vulnerabilidad de omisión de control de acceso encontrada en 389-ds-base. Ese manejo inapropiado del filtro que daría resultados incorrectos, pero a medida que ha avanzado, puede determinarse que en realidad es una omisión de control de acceso. • https://bugzilla.redhat.com/show_bug.cgi?id=2091781 • CWE-639: Authorization Bypass Through User-Controlled Key •

https://notcve.org/view.php?id=CVE-2022-1462
An out-of-bounds read flaw was found in the Linux kernel’s TeleTYpe subsystem. The issue occurs in how a user triggers a race condition using ioctls TIOCSPTLCK and TIOCGPTPEER and TIOCSTI and TCXONC with leakage of memory in the flush_to_ldisc function. This flaw allows a local user to crash the system or read unauthorized random data from memory. Se ha encontrado un fallo de lectura fuera de límites en el subsistema TeleTYpe del kernel de Linux.
