| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 2021-05-26 | CVE-2021-22543 | Improper Restriction of Operations within the Bounds of a Memory Buffer vulnerability in multiple products An issue was discovered in Linux: KVM through Improper handling of VM_IO|VM_PFNMAP vmas in KVM can bypass RO checks and can lead to pages being freed while still accessible by the VMM and guest. | 7.8 |
| 2021-05-25 | CVE-2020-25672 | A memory leak vulnerability was found in Linux kernel in llcp_sock_connect | 7.5 |
| 2021-05-24 | CVE-2020-26558 | Improper Authentication vulnerability in multiple products 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. | 4.2 |
| 2021-05-21 | CVE-2021-31440 | This vulnerability allows local attackers to escalate privileges on affected installations of Linux Kernel 5.11.15. | 7.0 |
| 2021-05-18 | CVE-2002-2438 | Unspecified vulnerability in Linux Kernel TCP firewalls could be circumvented by sending a SYN Packets with other flags (like e.g. | 7.5 |
| 2021-05-17 | CVE-2021-3483 | A flaw was found in the Nosy driver in the Linux kernel. | 7.8 |
| 2021-05-14 | CVE-2019-25044 | Use After Free vulnerability in multiple products The block subsystem in the Linux kernel before 5.2 has a use-after-free that can lead to arbitrary code execution in the kernel context and privilege escalation, aka CID-c3e2219216c9. | 7.8 |
| 2021-05-14 | CVE-2021-33033 | Use After Free vulnerability in Linux Kernel The Linux kernel before 5.11.14 has a use-after-free in cipso_v4_genopt in net/ipv4/cipso_ipv4.c because the CIPSO and CALIPSO refcounting for the DOI definitions is mishandled, aka CID-ad5d07f4a9cd. | 7.8 |
| 2021-05-14 | CVE-2021-33034 | Use After Free vulnerability in multiple products In the Linux kernel before 5.12.4, net/bluetooth/hci_event.c has a use-after-free when destroying an hci_chan, aka CID-5c4c8c954409. | 7.8 |
| 2021-05-13 | CVE-2020-27830 | 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. | 5.5 |
