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-2022-1789
With shadow paging enabled, the INVPCID instruction results in a call to kvm_mmu_invpcid_gva. If INVPCID is executed with CR0.PG=0, the invlpg callback is not set and the result is a NULL pointer dereference. Con shadow paging habilitada, la instrucción INVPCID resulta en una llamada a kvm_mmu_invpcid_gva. Si INVPCID es ejecutado con CR0.PG=0, la llamada de retorno invlpg no es establecida y el resultado es una desreferencia de puntero NULL A flaw was found in KVM. With shadow paging enabled if INVPCID is executed with CR0.PG=0, the invlpg callback is not set, and the result is a NULL pointer dereference. • https://bugzilla.redhat.com/show_bug.cgi?id=1832397 https://francozappa.github.io/about-bias https://kb.cert.org/vuls/id/647177 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/H6JP355XFVAB33X4BNO3ERVTURFYEDB7 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/IBUOQTNTQ4ZCXHOCNKYIL2ZUIAZ675RD https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/KCEAPIVPRTJHKPF2A2HVF5XHD5XJT3MN https://www.debian.org/security • CWE-476: NULL Pointer Dereference •

Linux Kernel could allow a local attacker to execute arbitrary code on the system, caused by a concurrency use-after-free flaw in the bad_flp_intr function. By executing a specially-crafted program, an attacker could exploit this vulnerability to execute arbitrary code or cause a denial of service condition on the system. El Kernel de Linux podría permitir a un atacante local ejecutar código arbitrario en el sistema, causado por un fallo de uso de memoria previamente liberada concurrente en la función bad_flp_intr. Al ejecutar un programa especialmente diseñado, un atacante podría explotar esta vulnerabilidad para ejecutar código arbitrario o causar una condición de denegación de servicio en el sistema • https://bugzilla.redhat.com/show_bug.cgi?id=1832397 https://francozappa.github.io/about-bias https://kb.cert.org/vuls/id/647177 https://security.netapp.com/advisory/ntap-20220722-0002 https://www.debian.org/security/2022/dsa-5173 • CWE-416: Use After Free •

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. El problema es producido en la forma en que un usuario desencadena una condición de carrera usando los ioctls TIOCSPTLCK y TIOCGPTPEER y TIOCSTI y TCXONC con fuga de memoria en la función flush_to_ldisc. • https://bugzilla.redhat.com/show_bug.cgi?id=2078466 https://lists.debian.org/debian-lts-announce/2022/10/msg00000.html https://seclists.org/oss-sec/2022/q2/155 https://access.redhat.com/security/cve/CVE-2022-1462 • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') CWE-366: Race Condition within a Thread •

A denial of service (DOS) issue was found in the Linux kernel’s smb2_ioctl_query_info function in the fs/cifs/smb2ops.c Common Internet File System (CIFS) due to an incorrect return from the memdup_user function. This flaw allows a local, privileged (CAP_SYS_ADMIN) attacker to crash the system. Se encontró un problema de denegación de servicio (DOS) en la función smb2_ioctl_query_info del kernel de Linux en el archivo fs/cifs/smb2ops.c Common Internet File System (CIFS) debido a un retorno incorrecto de la función memdup_user. Este fallo permite a un atacante local privilegiado (CAP_SYS_ADMIN) bloquear el sistema. • https://access.redhat.com/security/cve/CVE-2022-0168 https://bugzilla.redhat.com/show_bug.cgi?id=2037386 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=d6f5e358452479fa8a773b5c6ccc9e4ec5a20880 • CWE-476: NULL Pointer Dereference •
