A use-after-free flaw was found in the Linux kernel’s Bluetooth subsystem in the way user calls connect to the socket and disconnect simultaneously due to a race condition. This flaw allows a user to crash the system or escalate their privileges. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability. Se ha encontrado un fallo de uso de memoria previamente liberada en el subsistema Bluetooth del kernel de Linux en la forma en que las llamadas de usuario son conectadas al socket y son desconectadas simultáneamente debido a una condición de carrera. Este fallo permite a un usuario bloquear el sistema o escalar sus privilegios. • https://bugzilla.redhat.com/show_bug.cgi?id=1999544 https://lists.debian.org/debian-lts-announce/2022/03/msg00011.html https://lists.debian.org/debian-lts-announce/2022/03/msg00012.html https://lore.kernel.org/lkml/20211115165435.133245729%40linuxfoundation.org https://security.netapp.com/advisory/ntap-20220318-0009 https://www.debian.org/security/2022/dsa-5096 https://www.openwall.com/lists/oss-security/2021/09/15/4 https://www.oracle.com/security-alerts/cpujul2022.html https:/ • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') CWE-416: Use After Free •

A flaw was found in the KVM's AMD code for supporting SVM nested virtualization. The flaw occurs when processing the VMCB (virtual machine control block) provided by the L1 guest to spawn/handle a nested guest (L2). Due to improper validation of the "virt_ext" field, this issue could allow a malicious L1 to disable both VMLOAD/VMSAVE intercepts and VLS (Virtual VMLOAD/VMSAVE) for the L2 guest. As a result, the L2 guest would be allowed to read/write physical pages of the host, resulting in a crash of the entire system, leak of sensitive data or potential guest-to-host escape. Se ha encontrado un fallo en el código AMD de KVM para soportar la virtualización anidada SVM. • https://github.com/rami08448/CVE-2021-3656-Demo https://bugzilla.redhat.com/show_bug.cgi?id=1983988 https://git.kernel.org/pub/scm/virt/kvm/kvm.git/commit/?id=c7dfa4009965a9b2d7b329ee970eb8da0d32f0bc https://github.com/torvalds/linux/commit/c7dfa4009965a9b2d7b329ee970eb8da0d32f0bc https://www.openwall.com/lists/oss-security/2021/08/16/1 https://access.redhat.com/security/cve/CVE-2021-3656 • CWE-862: Missing Authorization •

A vulnerability was found in Linux Kernel, where a Heap Overflow was found in mwifiex_set_wmm_params() function of Marvell Wifi Driver. Se encontró una vulnerabilidad en Linux Kernel, donde se encontró un desbordamiento de pila en la función mwifiex_set_wmm_params () del controlador Marvell Wifi. A vulnerability found in the Linux kernel's WMM implementation for Marvell WiFi-based hardware (mwifiex) could lead to a denial of service or allow arbitrary code execution. For this flaw to be executed, the attacker must be both local and privileged. There is no mitigation to this flaw. • https://access.redhat.com/errata/RHSA-2020:0174 https://access.redhat.com/errata/RHSA-2020:0328 https://access.redhat.com/errata/RHSA-2020:0339 https://access.redhat.com/security/cve/cve-2019-14815 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2019-14815 https://github.com/torvalds/linux/commit/7caac62ed598a196d6ddf8d9c121e12e082cac3a https://lists.debian.org/debian-lts-announce/2020/03/msg00001.html https://lore.kernel.org/linux-wireless/20190828020751.13625-1-huangwenabc%40gmail.com https:&# • CWE-122: Heap-based Buffer Overflow CWE-787: Out-of-bounds Write •

There is heap-based buffer overflow in kernel, all versions up to, excluding 5.3, in the marvell wifi chip driver in Linux kernel, that allows local users to cause a denial of service(system crash) or possibly execute arbitrary code. Se presenta un desbordamiento del búfer en la región heap de la memoria en el kernel, todas las versiones hasta 5.3 (excluyéndola), en el controlador de chip wifi marvell en el kernel de Linux, que permite a usuarios locales causar una denegación de servicio (bloqueo del sistema) o posiblemente ejecutar código arbitrario. A vulnerability was found in the Linux kernel's Marvell WiFi chip driver. Where, while parsing vendor-specific informational attributes, an attacker on the same WiFi physical network segment could cause a system crash, resulting in a denial of service, or potentially execute arbitrary code. This flaw affects the network interface at the most basic level meaning the attacker only needs to affiliate with the same network device as the vulnerable system to create an attack path. • http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00064.html http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00066.html http://packetstormsecurity.com/files/154951/Kernel-Live-Patch-Security-Notice-LSN-0058-1.html http://packetstormsecurity.com/files/155212/Slackware-Security-Advisory-Slackware-14.2-kernel-Updates.html http://www.openwall.com/lists/oss-security/2019/08/28/1 https://access.redhat.com/errata/RHSA-2020:0174 https://access.redhat.com/errata/RHSA-2020:0204&# • CWE-122: Heap-based Buffer Overflow CWE-787: Out-of-bounds Write •
