| CVE-2020-27675 | 3 Debian, Fedoraproject, Linux | 3 Debian Linux, Fedora, Linux Kernel | 2024-08-04 | 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 | 2024-08-04 | 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 | 2024-08-04 | 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-2020-27170 | 5 Canonical, Debian, Fedoraproject and 2 more | 6 Ubuntu Linux, Debian Linux, Fedora and 3 more | 2024-08-04 | 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-2020-27171 | 4 Canonical, Debian, Fedoraproject and 1 more | 4 Ubuntu Linux, Debian Linux, Fedora and 1 more | 2024-08-04 | 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-2020-27152 | 2 Linux, Redhat | 2 Linux Kernel, Enterprise Linux | 2024-08-04 | 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-2020-26541 | 2 Linux, Redhat | 4 Linux Kernel, Enterprise Linux, Rhel Eus and 1 more | 2024-08-04 | 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-2020-26558 | 6 Bluetooth, Debian, Fedoraproject and 3 more | 35 Bluetooth Core Specification, Debian Linux, Fedora and 32 more | 2024-08-04 | 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-2020-26147 | 5 Arista, Debian, Linux and 2 more | 15 C-65, C-65 Firmware, C-75 and 12 more | 2024-08-04 | 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. | ||||
| CVE-2020-26088 | 4 Canonical, Debian, Linux and 1 more | 4 Ubuntu Linux, Debian Linux, Linux Kernel and 1 more | 2024-08-04 | 5.5 Medium |
| A missing CAP_NET_RAW check in NFC socket creation in net/nfc/rawsock.c in the Linux kernel before 5.8.2 could be used by local attackers to create raw sockets, bypassing security mechanisms, aka CID-26896f01467a. | ||||
| CVE-2020-25669 | 3 Debian, Linux, Netapp | 21 Debian Linux, Linux Kernel, Cloud Backup and 18 more | 2024-08-04 | 7.8 High |
| A vulnerability was found in the Linux Kernel where the function sunkbd_reinit having been scheduled by sunkbd_interrupt before sunkbd being freed. Though the dangling pointer is set to NULL in sunkbd_disconnect, there is still an alias in sunkbd_reinit causing Use After Free. | ||||
| CVE-2020-25668 | 3 Debian, Linux, Netapp | 26 Debian Linux, Linux Kernel, 500f and 23 more | 2024-08-04 | 7.0 High |

| CVE-2020-25645 | 6 Canonical, Debian, Linux and 3 more | 10 Ubuntu Linux, Debian Linux, Linux Kernel and 7 more | 2024-08-04 | 7.5 High |
| A flaw was found in the Linux kernel in versions before 5.9-rc7. Traffic between two Geneve endpoints may be unencrypted when IPsec is configured to encrypt traffic for the specific UDP port used by the GENEVE tunnel allowing anyone between the two endpoints to read the traffic unencrypted. The main threat from this vulnerability is to data confidentiality. | ||||
| CVE-2020-25641 | 5 Canonical, Debian, Linux and 2 more | 6 Ubuntu Linux, Debian Linux, Linux Kernel and 3 more | 2024-08-04 | 5.5 Medium |
| A flaw was found in the Linux kernel's implementation of biovecs in versions before 5.9-rc7. A zero-length biovec request issued by the block subsystem could cause the kernel to enter an infinite loop, causing a denial of service. This flaw allows a local attacker with basic privileges to issue requests to a block device, resulting in a denial of service. The highest threat from this vulnerability is to system availability. | ||||
