| CVE-2020-35495 | 4 Broadcom, Fedoraproject, Gnu and 1 more | 9 Brocade Fabric Operating System Firmware, Fedora, Binutils and 6 more | 2024-11-21 | 5.5 Medium |
| There's a flaw in binutils /bfd/pef.c. An attacker who is able to submit a crafted input file to be processed by the objdump program could cause a null pointer dereference. The greatest threat from this flaw is to application availability. This flaw affects binutils versions prior to 2.34. | ||||

| CVE-2020-29652 | 2 Golang, Redhat | 4 Ssh, Container Native Virtualization, Enterprise Linux and 1 more | 2024-11-21 | 7.5 High |
| A nil pointer dereference in the golang.org/x/crypto/ssh component through v0.0.0-20201203163018-be400aefbc4c for Go allows remote attackers to cause a denial of service against SSH servers. | ||||
| CVE-2020-29571 | 3 Debian, Fedoraproject, Xen | 3 Debian Linux, Fedora, Xen | 2024-11-21 | 6.2 Medium |
| An issue was discovered in Xen through 4.14.x. A bounds check common to most operation time functions specific to FIFO event channels depends on the CPU observing consistent state. While the producer side uses appropriately ordered writes, the consumer side isn't protected against re-ordered reads, and may hence end up de-referencing a NULL pointer. Malicious or buggy guest kernels can mount a Denial of Service (DoS) attack affecting the entire system. Only Arm systems may be vulnerable. Whether a system is vulnerable depends on the specific CPU. x86 systems are not vulnerable. | ||||
| CVE-2020-29484 | 3 Debian, Fedoraproject, Xen | 3 Debian Linux, Fedora, Xen | 2024-11-21 | 6.0 Medium |
| An issue was discovered in Xen through 4.14.x. When a Xenstore watch fires, the xenstore client that registered the watch will receive a Xenstore message containing the path of the modified Xenstore entry that triggered the watch, and the tag that was specified when registering the watch. Any communication with xenstored is done via Xenstore messages, consisting of a message header and the payload. The payload length is limited to 4096 bytes. Any request to xenstored resulting in a response with a payload longer than 4096 bytes will result in an error. When registering a watch, the payload length limit applies to the combined length of the watched path and the specified tag. Because watches for a specific path are also triggered for all nodes below that path, the payload of a watch event message can be longer than the payload needed to register the watch. A malicious guest that registers a watch using a very large tag (i.e., with a registration operation payload length close to the 4096 byte limit) can cause the generation of watch events with a payload length larger than 4096 bytes, by writing to Xenstore entries below the watched path. This will result in an error condition in xenstored. This error can result in a NULL pointer dereference, leading to a crash of xenstored. A malicious guest administrator can cause xenstored to crash, leading to a denial of service. Following a xenstored crash, domains may continue to run, but management operations will be impossible. Only C xenstored is affected, oxenstored is not affected. | ||||
| CVE-2020-28941 | 3 Debian, Fedoraproject, Linux | 3 Debian Linux, Fedora, Linux Kernel | 2024-11-21 | 5.5 Medium |
| An issue was discovered in drivers/accessibility/speakup/spk_ttyio.c in the Linux kernel through 5.9.9. Local attackers on systems with the speakup driver could cause a local denial of service attack, aka CID-d41227544427. This occurs because of an invalid free when the line discipline is used more than once. | ||||
| CVE-2020-28346 | 1 Projectacrn | 1 Acrn | 2024-11-21 | 7.5 High |
| ACRN through 2.2 has a devicemodel/hw/pci/virtio/virtio.c NULL Pointer Dereference. | ||||
| CVE-2020-28345 | 1 Google | 1 Android | 2024-11-21 | 7.5 High |
| An issue was discovered on LG mobile devices with Android OS 10 software. The Wi-Fi subsystem may crash because of the lack of a NULL parameter check. The LG ID is LVE-SMP-200025 (November 2020). | ||||
| CVE-2020-28344 | 1 Google | 1 Android | 2024-11-21 | 7.5 High |
| An issue was discovered on LG mobile devices with Android OS 8.0, 8.1, 9.0, and 10 software. System services may crash because of the lack of a NULL parameter check. The LG ID is LVE-SMP-200024 (November 2020). | ||||
| CVE-2020-28203 | 1 Foxitsoftware | 2 Foxit Reader, Phantompdf | 2024-11-21 | 5.5 Medium |
| An issue was discovered in Foxit Reader and PhantomPDF 10.1.0.37527 and earlier. There is a null pointer access/dereference while opening a crafted PDF file, leading the application to crash (denial of service). | ||||
| CVE-2020-27830 | 2 Debian, Linux | 2 Debian Linux, Linux Kernel | 2024-11-21 | 5.5 Medium |
| A vulnerability was found in Linux Kernel where in the spk_ttyio_receive_buf2() function, it would dereference spk_ttyio_synth without checking whether it is NULL or not, and may lead to a NULL-ptr deref crash. | ||||
| CVE-2020-27819 | 1 Libxls Project | 1 Libxls | 2024-11-21 | 5.5 Medium |
| An issue was discovered in libxls before and including 1.6.1 when reading Microsoft Excel files. A NULL pointer dereference vulnerability exists when parsing XLS cells in libxls/xls2csv.c:199. It could allow a remote attacker to cause a denial of service via crafted XLS file. | ||||
| CVE-2020-27675 | 3 Debian, Fedoraproject, Linux | 3 Debian Linux, Fedora, Linux Kernel | 2024-11-21 | 4.7 Medium |
| An issue was discovered in the Linux kernel through 5.9.1, as used with Xen through 4.14.x. drivers/xen/events/events_base.c allows event-channel removal during the event-handling loop (a race condition). This can cause a use-after-free or NULL pointer dereference, as demonstrated by a dom0 crash via events for an in-reconfiguration paravirtualized device, aka CID-073d0552ead5. | ||||
| CVE-2020-27289 | 1 Deltaww | 1 Cncsoft-b | 2024-11-21 | 7.8 High |

| CVE-2020-27279 | 1 Redlion | 1 Crimson | 2024-11-21 | 7.5 High |
| A NULL pointer deference vulnerability has been identified in the protocol converter. An attacker could send a specially crafted packet that could reboot the device running Crimson 3.1 (Build versions prior to 3119.001). | ||||
| CVE-2020-27277 | 1 Deltaww | 1 Dopsoft | 2024-11-21 | 7.8 High |

| CVE-2020-26991 | 1 Siemens | 2 Jt2go, Teamcenter Visualization | 2024-11-21 | 8.8 High |
| A vulnerability has been identified in JT2Go (All versions < V13.1.0.2), Teamcenter Visualization (All versions < V13.1.0.2). Affected applications lack proper validation of user-supplied data when parsing ASM files. This could lead to pointer dereferences of a value obtained from untrusted source. An attacker could leverage this vulnerability to execute code in the context of the current process. (ZDI-CAN-11899) | ||||
