CVSS: 6.5EPSS: 0%CPEs: 324EXPL: 0CVE-2019-11135 – hw: TSX Transaction Asynchronous Abort (TAA)
https://notcve.org/view.php?id=CVE-2019-11135
TSX Asynchronous Abort condition on some CPUs utilizing speculative execution may allow an authenticated user to potentially enable information disclosure via a side channel with local access. Una condición de tipo TSX Asynchronous Abort en algunas CPU que utilizan ejecución especulativa puede habilitar a un usuario autenticado para permitir potencialmente una divulgación de información por medio de un canal lateral con acceso local. A flaw was found in the way Intel CPUs handle speculative execution of instructions when the TSX Asynchronous Abort (TAA) error occurs. A local authenticated attacker with the ability to monitor execution times could infer the TSX memory state by comparing abort execution times. This could allow information disclosure via this observed side-channel for any TSX transaction being executed while an attacker is able to observe abort timing. Intel's Transactional Synchronisation Extensions (TSX) are set of instructions which enable transactional memory support to improve performance of the multi-threaded applications, in the lock-protected critical sections. • http://lists.opensuse.org/opensuse-security-announce/2019-11/msg00045.html http://lists.opensuse.org/opensuse-security-announce/2019-11/msg00046.html http://lists.opensuse.org/opensuse-security-announce/2019-12/msg00042.html http://packetstormsecurity.com/files/155375/Slackware-Security-Advisory-Slackware-14.2-kernel-Updates.html http://www.openwall.com/lists/oss-security/2019/12/10/3 http://www.openwall.com/lists/oss-security/2019/12/10/4 http://www.openwall.com/lists/oss-security/2019/12 • CWE-203: Observable Discrepancy •

A memory leak in the ccp_run_sha_cmd() function in drivers/crypto/ccp/ccp-ops.c in the Linux kernel through 5.3.9 allows attackers to cause a denial of service (memory consumption), aka CID-128c66429247. Una pérdida de memoria en la función ccp_run_sha_cmd() en el archivo drivers/crypto/ccp/ccp-ops.c en el kernel de Linux versiones hasta 5.3.9, permite a atacantes causar una denegación de servicio (consumo de memoria), también se conoce como CID-128c66429247. A flaw was found in the AMD Cryptographic Co-processor driver in the Linux kernel. An attacker, able to send invalid SHA type commands, could cause the system to crash. The highest threat from this vulnerability is to system availability. • http://lists.opensuse.org/opensuse-security-announce/2020-03/msg00021.html http://www.openwall.com/lists/oss-security/2021/09/14/1 https://github.com/torvalds/linux/commit/128c66429247add5128c03dc1e144ca56f05a4e2 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/LYIFGYEDQXP5DVJQQUARQRK2PXKBKQGY https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/YWWOOJKZ4NQYN4RMFIVJ3ZIXKJJI3MKP https://security.netapp.com/advisory/ntap-20191205-0001 https://usn.ubun • CWE-400: Uncontrolled Resource Consumption CWE-401: Missing Release of Memory after Effective Lifetime •

https://notcve.org/view.php?id=CVE-2019-18683
An issue was discovered in drivers/media/platform/vivid in the Linux kernel through 5.3.8. It is exploitable for privilege escalation on some Linux distributions where local users have /dev/video0 access, but only if the driver happens to be loaded. There are multiple race conditions during streaming stopping in this driver (part of the V4L2 subsystem). These issues are caused by wrong mutex locking in vivid_stop_generating_vid_cap(), vivid_stop_generating_vid_out(), sdr_cap_stop_streaming(), and the corresponding kthreads. At least one of these race conditions leads to a use-after-free. • https://github.com/sanjana123-cloud/CVE-2019-18683 http://lists.opensuse.org/opensuse-security-announce/2019-12/msg00029.html http://packetstormsecurity.com/files/155890/Slackware-Security-Advisory-Slackware-14.2-kernel-Updates.html http://www.openwall.com/lists/oss-security/2019/11/05/1 https://lists.debian.org/debian-lts-announce/2020/03/msg00001.html https://lore.kernel.org/lkml/20191103221719.27118-1-alex.popov%40linux.com https://seclists.org/bugtraq/2020/Jan/10 https://security.net • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') CWE-416: Use After Free •
