| CVE-2019-14821 | An out-of-bounds access issue was found in the Linux kernel, all versions through 5.3, in the way Linux kernel's KVM hypervisor implements the Coalesced MMIO write operation. It operates on an MMIO ring buffer 'struct kvm_coalesced_mmio' object, wherein write indices 'ring->first' and 'ring->last' value could be supplied by a host user-space process. An unprivileged host user or process with access to '/dev/kvm' device could use this flaw to crash the host kernel, resulting in a denial of servic | [email protected] | 8.8 | 0.76% | 2019-09-19 | 2026-06-16 |
| CVE-2019-14835 | A buffer overflow flaw was found, in versions from 2.6.34 to 5.2.x, in the way Linux kernel's vhost functionality that translates virtqueue buffers to IOVs, logged the buffer descriptors during migration. A privileged guest user able to pass descriptors with invalid length to the host when migration is underway, could use this flaw to increase their privileges on the host. | [email protected] | 7.8 | 0.63% | 2019-09-17 | 2026-06-16 |
| CVE-2019-1125 | An information disclosure vulnerability exists when certain central processing units (CPU) speculatively access memory. An attacker who successfully exploited the vulnerability could read privileged data across trust boundaries. To exploit this vulnerability, an attacker would have to log on to an affected system and run a specially crafted application. The vulnerability would not allow an attacker to elevate user rights directly, but it could be used to obtain information that could be used to | [email protected] | 5.6 | 4.52% | 2019-09-03 | 2026-06-16 |
| CVE-2019-10161 | It was discovered that libvirtd before versions 4.10.1 and 5.4.1 would permit read-only clients to use the virDomainSaveImageGetXMLDesc() API, specifying an arbitrary path which would be accessed with the permissions of the libvirtd process. An attacker with access to the libvirtd socket could use this to probe the existence of arbitrary files, cause denial of service or cause libvirtd to execute arbitrary programs. | [email protected] | 7.8 | 0.52% | 2019-07-30 | 2026-06-16 |
| CVE-2019-11479 | Jonathan Looney discovered that the Linux kernel default MSS is hard-coded to 48 bytes. This allows a remote peer to fragment TCP resend queues significantly more than if a larger MSS were enforced. A remote attacker could use this to cause a denial of service. This has been fixed in stable kernel releases 4.4.182, 4.9.182, 4.14.127, 4.19.52, 5.1.11, and is fixed in commits 967c05aee439e6e5d7d805e195b3a20ef5c433d6 and 5f3e2bf008c2221478101ee72f5cb4654b9fc363. | [email protected] | 7.5 | 91.66% | 2019-06-18 | 2026-06-16 |
| CVE-2019-3888 | A vulnerability was found in Undertow web server before 2.0.21. An information exposure of plain text credentials through log files because Connectors.executeRootHandler:402 logs the HttpServerExchange object at ERROR level using UndertowLogger.REQUEST_LOGGER.undertowRequestFailed(t, exchange) | [email protected] | 9.8 | 3.41% | 2019-06-12 | 2026-06-16 |
| CVE-2019-3460 | A heap data infoleak in multiple locations including L2CAP_PARSE_CONF_RSP was found in the Linux kernel before 5.1-rc1. | [email protected] | 6.5 | 1.84% | 2019-04-11 | 2026-06-16 |
| CVE-2019-1559 | If an application encounters a fatal protocol error and then calls SSL_shutdown() twice (once to send a close_notify, and once to receive one) then OpenSSL can respond differently to the calling application if a 0 byte record is received with invalid padding compared to if a 0 byte record is received with an invalid MAC. If the application then behaves differently based on that in a way that is detectable to the remote peer, then this amounts to a padding oracle that could be used to decrypt dat | [email protected] | 5.9 | 17.14% | 2019-02-27 | 2026-06-16 |
| CVE-2018-16881 | A denial of service vulnerability was found in rsyslog in the imptcp module. An attacker could send a specially crafted message to the imptcp socket, which would cause rsyslog to crash. Versions before 8.27.0 are vulnerable. | [email protected] | 7.5 | 2.24% | 2019-01-25 | 2026-06-16 |
| CVE-2018-18397 | The userfaultfd implementation in the Linux kernel before 4.19.7 mishandles access control for certain UFFDIO_ ioctl calls, as demonstrated by allowing local users to write data into holes in a tmpfs file (if the user has read-only access to that file, and that file contains holes), related to fs/userfaultfd.c and mm/userfaultfd.c. | [email protected] | 5.5 | 0.51% | 2018-12-12 | 2026-06-16 |
| CVE-2018-14660 | A flaw was found in glusterfs server through versions 4.1.4 and 3.1.2 which allowed repeated usage of GF_META_LOCK_KEY xattr. A remote, authenticated attacker could use this flaw to create multiple locks for single inode by using setxattr repetitively resulting in memory exhaustion of glusterfs server node. | [email protected] | 6.5 | 2.51% | 2018-11-01 | 2026-06-16 |
| CVE-2018-14661 | It was found that usage of snprintf function in feature/locks translator of glusterfs server 3.8.4, as shipped with Red Hat Gluster Storage, was vulnerable to a format string attack. A remote, authenticated attacker could use this flaw to cause remote denial of service. | [email protected] | 6.5 | 2.66% | 2018-10-31 | 2026-06-16 |
