|---|---|---|---|
| 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 |
| 2021-05-11 | CVE-2020-24586 | The 802.11 standard that underpins Wi-Fi Protected Access (WPA, WPA2, and WPA3) and Wired Equivalent Privacy (WEP) doesn't require that received fragments be cleared from memory after (re)connecting to a network. | 2.9 |
| 2021-05-11 | CVE-2020-24587 | Use of a Broken or Risky Cryptographic Algorithm vulnerability in multiple products The 802.11 standard that underpins Wi-Fi Protected Access (WPA, WPA2, and WPA3) and Wired Equivalent Privacy (WEP) doesn't require that all fragments of a frame are encrypted under the same key. | 1.8 |
| 2021-05-11 | CVE-2020-24588 | Use of a Broken or Risky Cryptographic Algorithm vulnerability in multiple products The 802.11 standard that underpins Wi-Fi Protected Access (WPA, WPA2, and WPA3) and Wired Equivalent Privacy (WEP) doesn't require that the A-MSDU flag in the plaintext QoS header field is authenticated. | 3.5 |
| 2021-05-11 | CVE-2020-26147 | An issue was discovered in the Linux kernel 5.8.9. | 3.2 |
| 2021-05-10 | CVE-2021-32399 | Race Condition vulnerability in multiple products net/bluetooth/hci_request.c in the Linux kernel through 5.12.2 has a race condition for removal of the HCI controller. | 4.4 |
| 2021-05-06 | CVE-2021-31916 | Out-of-bounds Write vulnerability in multiple products An out-of-bounds (OOB) memory write flaw was found in list_devices in drivers/md/dm-ioctl.c in the Multi-device driver module in the Linux kernel before 5.12. | 6.1 |
