https://notcve.org/view.php?id=CVE-2022-1011
A use-after-free flaw was found in the Linux kernel’s FUSE filesystem in the way a user triggers write(). This flaw allows a local user to gain unauthorized access to data from the FUSE filesystem, resulting in privilege escalation. Se ha encontrado un fallo de uso después de libre en el sistema de archivos FUSE del kernel de Linux en la forma en que un usuario activa write(). Este defecto permite a un usuario local obtener acceso no autorizado a los datos del sistema de archivos FUSE, lo que resulta en una escalada de privilegios Linux suffers from a vulnerability where FUSE allows use-after-free reads of write() buffers, allowing theft of (partial) /etc/shadow hashes. • https://github.com/xkaneiki/CVE-2022-1011 https://bugzilla.redhat.com/show_bug.cgi?id=2064855 https://git.kernel.org/pub/scm/linux/kernel/git/mszeredi/fuse.git/commit/?h=for-next https://lists.debian.org/debian-lts-announce/2022/07/msg00000.html https://www.debian.org/security/2022/dsa-5173 https://www.oracle.com/security-alerts/cpujul2022.html https://access.redhat.com/security/cve/CVE-2022-1011 • CWE-416: Use After Free •

A memory leak flaw was found in the Linux kernel in the ccp_run_aes_gcm_cmd() function in drivers/crypto/ccp/ccp-ops.c, which allows attackers to cause a denial of service (memory consumption). This vulnerability is similar with the older CVE-2019-18808. Se ha encontrado un fallo de pérdida de memoria en el kernel de Linux en la función ccp_run_aes_gcm_cmd() en el archivo drivers/crypto/ccp/ccp-ops.c, que permite a atacantes causar una denegación de servicio (consumo de memoria). Esta vulnerabilidad es similar a la anterior CVE-2019-18808 A flaw was found in the Linux kernel. A memory leak in the ccp-ops crypto driver can allow attackers to cause a denial of service. • http://www.openwall.com/lists/oss-security/2021/09/14/1 https://bugzilla.redhat.com/show_bug.cgi?id=2000627 https://github.com/torvalds/linux/commit/505d9dcb0f7ddf9d075e729523a33d38642ae680 https://kernel.googlesource.com/pub/scm/linux/kernel/git/herbert/crypto-2.6/+/505d9dcb0f7ddf9d075e729523a33d38642ae680%5E%21/#F0 https://lists.debian.org/debian-lts-announce/2022/03/msg00012.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/7BLLVKYAIETEORUPTFO3TR3C33ZPFXQM https: • CWE-401: Missing Release of Memory after Effective Lifetime •

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 •
CVSS: 7.8EPSS: 0%CPEs: 43EXPL: 22CVE-2019-13272 – Linux Kernel Improper Privilege Management Vulnerability
https://notcve.org/view.php?id=CVE-2019-13272
In the Linux kernel before 5.1.17, ptrace_link in kernel/ptrace.c mishandles the recording of the credentials of a process that wants to create a ptrace relationship, which allows local users to obtain root access by leveraging certain scenarios with a parent-child process relationship, where a parent drops privileges and calls execve (potentially allowing control by an attacker). One contributing factor is an object lifetime issue (which can also cause a panic). Another contributing factor is incorrect marking of a ptrace relationship as privileged, which is exploitable through (for example) Polkit's pkexec helper with PTRACE_TRACEME. NOTE: SELinux deny_ptrace might be a usable workaround in some environments. En el kernel de Linux anterior a versión 5.1.17, ptrace_link en el archivo kernel/ptrace.c maneja inapropiadamente la grabación de las credenciales de un proceso que desea crear una relación de ptrace, que permite a los usuarios locales obtener acceso de root aprovechando determinados escenarios con un relación de proceso padre-hijo, donde un padre elimina los privilegios y llama a execve (permitiendo potencialmente el control por parte de un atacante). • https://www.exploit-db.com/exploits/47133 https://www.exploit-db.com/exploits/47163 https://www.exploit-db.com/exploits/50541 https://www.exploit-db.com/exploits/47543 https://github.com/jas502n/CVE-2019-13272 https://github.com/Cyc1eC/CVE-2019-13272 https://github.com/oneoy/CVE-2019-13272 https://github.com/polosec/CVE-2019-13272 https://github.com/MDS1GNAL/ptrace_scope-CVE-2019-13272-privilege-escalation https://github.com/datntsec/CVE-2019-13272 https://github • CWE-271: Privilege Dropping / Lowering Errors •

https://notcve.org/view.php?id=CVE-2019-11833
fs/ext4/extents.c in the Linux kernel through 5.1.2 does not zero out the unused memory region in the extent tree block, which might allow local users to obtain sensitive information by reading uninitialized data in the filesystem. fs / ext4 / extents.c en el kernel de Linux hasta 5.1.2 no pone a cero la región de memoria no utilizada en el bloque del árbol de extensión, lo que podría permitir a los usuarios locales obtener información confidencial al leer datos no inicializados en el sistema de archivos. A flaw was found in the Linux kernel's implementation of ext4 extent management. The kernel doesn't correctly initialize memory regions in the extent tree block which may be exported to a local user to obtain sensitive information by reading empty/uninitialized data from the filesystem. • http://lists.opensuse.org/opensuse-security-announce/2019-05/msg00071.html http://lists.opensuse.org/opensuse-security-announce/2019-06/msg00039.html http://lists.opensuse.org/opensuse-security-announce/2019-06/msg00048.html http://packetstormsecurity.com/files/154951/Kernel-Live-Patch-Security-Notice-LSN-0058-1.html http://www.securityfocus.com/bid/108372 https://access.redhat.com/errata/RHSA-2019:2029 https://access.redhat.com/errata/RHSA-2019:2043 https://access.redhat.com/errata/RHSA-2019 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-908: Use of Uninitialized Resource •
