| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 2021-05-26 | CVE-2020-25668 | Improper Synchronization vulnerability in multiple products A flaw was found in Linux Kernel because access to the global variable fg_console is not properly synchronized leading to a use after free in con_font_op. | 7.0 |
| 2021-05-26 | CVE-2020-25669 | Use After Free vulnerability in multiple products A vulnerability was found in the Linux Kernel where the function sunkbd_reinit having been scheduled by sunkbd_interrupt before sunkbd being freed. | 7.8 |
| 2021-05-26 | CVE-2020-25670 | Use After Free vulnerability in multiple products A vulnerability was found in Linux Kernel where refcount leak in llcp_sock_bind() causing use-after-free which might lead to privilege escalations. | 7.8 |
| 2021-05-26 | CVE-2020-25671 | Use After Free vulnerability in multiple products A vulnerability was found in Linux Kernel, where a refcount leak in llcp_sock_connect() causing use-after-free which might lead to privilege escalations. | 7.8 |
| 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 |
| 2021-05-17 | CVE-2021-3483 | Use After Free vulnerability in multiple products A flaw was found in the Nosy driver in the Linux kernel. | 4.6 |
| 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. | 4.6 |
| 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 | NULL Pointer Dereference vulnerability in multiple products 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. | 2.1 |
| 2021-05-12 | CVE-2021-23134 | Use After Free vulnerability in multiple products Use After Free vulnerability in nfc sockets in the Linux Kernel before 5.12.4 allows local attackers to elevate their privileges. | 7.8 |
