|---|---|---|---|---|
| CVE-2020-28588 | 1 Linux | 1 Linux Kernel | 2024-11-21 | 5.5 Medium |
| An information disclosure vulnerability exists in the /proc/pid/syscall functionality of Linux Kernel 5.1 Stable and 5.4.66. More specifically, this issue has been introduced in v5.1-rc4 (commit 631b7abacd02b88f4b0795c08b54ad4fc3e7c7c0) and is still present in v5.10-rc4, so it’s likely that all versions in between are affected. An attacker can read /proc/pid/syscall to trigger this vulnerability, which leads to the kernel leaking memory contents. | ||||
| CVE-2020-28374 | 4 Debian, Fedoraproject, Linux and 1 more | 9 Debian Linux, Fedora, Linux Kernel and 6 more | 2024-11-21 | 8.1 High |
| In drivers/target/target_core_xcopy.c in the Linux kernel before 5.10.7, insufficient identifier checking in the LIO SCSI target code can be used by remote attackers to read or write files via directory traversal in an XCOPY request, aka CID-2896c93811e3. For example, an attack can occur over a network if the attacker has access to one iSCSI LUN. The attacker gains control over file access because I/O operations are proxied via an attacker-selected backstore. | ||||
| CVE-2020-28097 | 2 Linux, Netapp | 18 Linux Kernel, Cloud Backup, H300e and 15 more | 2024-11-21 | 5.9 Medium |
| The vgacon subsystem in the Linux kernel before 5.8.10 mishandles software scrollback. There is a vgacon_scrolldelta out-of-bounds read, aka CID-973c096f6a85. | ||||
| CVE-2020-27835 | 2 Linux, Redhat | 2 Infiniband Hfi1 Driver, Enterprise Linux | 2024-11-21 | 4.4 Medium |
| A use after free in the Linux kernel infiniband hfi1 driver in versions prior to 5.10-rc6 was found in the way user calls Ioctl after open dev file and fork. A local user could use this flaw to crash the system. | ||||
| 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-2020-27825 | 4 Debian, Linux, Netapp and 1 more | 9 Debian Linux, Linux Kernel, Cloud Backup and 6 more | 2024-11-21 | 5.7 Medium |
| A use-after-free flaw was found in kernel/trace/ring_buffer.c in Linux kernel (before 5.10-rc1). There was a race problem in trace_open and resize of cpu buffer running parallely on different cpus, may cause a denial of service problem (DOS). This flaw could even allow a local attacker with special user privilege to a kernel information leak threat. | ||||
| CVE-2020-27820 | 4 Fedoraproject, Linux, Oracle and 1 more | 6 Fedora, Linux Kernel, Communications Cloud Native Core Binding Support Function and 3 more | 2024-11-21 | 4.7 Medium |
| A vulnerability was found in Linux kernel, where a use-after-frees in nouveau's postclose() handler could happen if removing device (that is not common to remove video card physically without power-off, but same happens if "unbind" the driver). | ||||
| CVE-2020-27815 | 3 Debian, Linux, Netapp | 22 Debian Linux, Linux Kernel, Aff A250 and 19 more | 2024-11-21 | 7.8 High |
| A flaw was found in the JFS filesystem code in the Linux Kernel which allows a local attacker with the ability to set extended attributes to panic the system, causing memory corruption or escalating privileges. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability. | ||||
| CVE-2020-27786 | 3 Linux, Netapp, Redhat | 6 Linux Kernel, Cloud Backup, Solidfire Baseboard Management Controller and 3 more | 2024-11-21 | 7.8 High |
| A flaw was found in the Linux kernel’s implementation of MIDI, where an attacker with a local account and the permissions to issue ioctl commands to midi devices could trigger a use-after-free issue. A write to this specific memory while freed and before use causes the flow of execution to change and possibly allow for memory corruption or privilege escalation. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability. | ||||
| CVE-2020-27784 | 1 Linux | 1 Linux Kernel | 2024-11-21 | 5.5 Medium |
| A vulnerability was found in the Linux kernel, where accessing a deallocated instance in printer_ioctl() printer_ioctl() tries to access of a printer_dev instance. However, use-after-free arises because it had been freed by gprinter_free(). | ||||
| CVE-2020-27777 | 2 Linux, Redhat | 3 Linux Kernel, Enterprise Linux, Openshift Container Platform | 2024-11-21 | 6.7 Medium |
| A flaw was found in the way RTAS handled memory accesses in userspace to kernel communication. On a locked down (usually due to Secure Boot) guest system running on top of PowerVM or KVM hypervisors (pseries platform) a root like local user could use this flaw to further increase their privileges to that of a running kernel. | ||||
| 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-2020-27673 | 4 Debian, Linux, Opensuse and 1 more | 4 Debian Linux, Linux Kernel, Leap and 1 more | 2024-11-21 | 5.5 Medium |
| An issue was discovered in the Linux kernel through 5.9.1, as used with Xen through 4.14.x. Guest OS users can cause a denial of service (host OS hang) via a high rate of events to dom0, aka CID-e99502f76271. | ||||
| CVE-2020-27194 | 1 Linux | 1 Linux Kernel | 2024-11-21 | 5.5 Medium |
| An issue was discovered in the Linux kernel before 5.8.15. scalar32_min_max_or in kernel/bpf/verifier.c mishandles bounds tracking during use of 64-bit values, aka CID-5b9fbeb75b6a. | ||||
| CVE-2020-27171 | 4 Canonical, Debian, Fedoraproject and 1 more | 4 Ubuntu Linux, Debian Linux, Fedora and 1 more | 2024-11-21 | 6.0 Medium |
| An issue was discovered in the Linux kernel before 5.11.8. kernel/bpf/verifier.c has an off-by-one error (with a resultant integer underflow) affecting out-of-bounds speculation on pointer arithmetic, leading to side-channel attacks that defeat Spectre mitigations and obtain sensitive information from kernel memory, aka CID-10d2bb2e6b1d. | ||||
| CVE-2020-27170 | 5 Canonical, Debian, Fedoraproject and 2 more | 6 Ubuntu Linux, Debian Linux, Fedora and 3 more | 2024-11-21 | 4.7 Medium |
| An issue was discovered in the Linux kernel before 5.11.8. kernel/bpf/verifier.c performs undesirable out-of-bounds speculation on pointer arithmetic, leading to side-channel attacks that defeat Spectre mitigations and obtain sensitive information from kernel memory, aka CID-f232326f6966. This affects pointer types that do not define a ptr_limit. | ||||
| CVE-2020-27152 | 2 Linux, Redhat | 2 Linux Kernel, Enterprise Linux | 2024-11-21 | 5.5 Medium |
| An issue was discovered in ioapic_lazy_update_eoi in arch/x86/kvm/ioapic.c in the Linux kernel before 5.9.2. It has an infinite loop related to improper interaction between a resampler and edge triggering, aka CID-77377064c3a9. | ||||
| CVE-2020-26558 | 6 Bluetooth, Debian, Fedoraproject and 3 more | 35 Bluetooth Core Specification, Debian Linux, Fedora and 32 more | 2024-11-21 | 4.2 Medium |
| Bluetooth LE and BR/EDR secure pairing in Bluetooth Core Specification 2.1 through 5.2 may permit a nearby man-in-the-middle attacker to identify the Passkey used during pairing (in the Passkey authentication procedure) by reflection of the public key and the authentication evidence of the initiating device, potentially permitting this attacker to complete authenticated pairing with the responding device using the correct Passkey for the pairing session. The attack methodology determines the Passkey value one bit at a time. | ||||
| CVE-2020-26541 | 2 Linux, Redhat | 4 Linux Kernel, Enterprise Linux, Rhel Eus and 1 more | 2024-11-21 | 6.5 Medium |
| The Linux kernel through 5.8.13 does not properly enforce the Secure Boot Forbidden Signature Database (aka dbx) protection mechanism. This affects certs/blacklist.c and certs/system_keyring.c. | ||||
| CVE-2020-26147 | 5 Arista, Debian, Linux and 2 more | 15 C-65, C-65 Firmware, C-75 and 12 more | 2024-11-21 | 5.4 Medium |
| An issue was discovered in the Linux kernel 5.8.9. The WEP, WPA, WPA2, and WPA3 implementations reassemble fragments even though some of them were sent in plaintext. This vulnerability can be abused to inject packets and/or exfiltrate selected fragments when another device sends fragmented frames and the WEP, CCMP, or GCMP data-confidentiality protocol is used. | ||||
