| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 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 |
| 2021-05-14 | 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 |
| 2021-05-12 | 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-2020-24588 | 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 |
| 2021-05-06 | CVE-2021-31829 | Incorrect Authorization vulnerability in multiple products kernel/bpf/verifier.c in the Linux kernel through 5.12.1 performs undesirable speculative loads, leading to disclosure of stack content via side-channel attacks, aka CID-801c6058d14a. | 5.5 |
| 2021-04-20 | CVE-2021-29155 | Out-of-bounds Read vulnerability in multiple products An issue was discovered in the Linux kernel through 5.11.x. | 5.5 |
| 2021-04-19 | CVE-2021-3506 | Out-of-bounds Read vulnerability in multiple products An out-of-bounds (OOB) memory access flaw was found in fs/f2fs/node.c in the f2fs module in the Linux kernel in versions before 5.12.0-rc4. | 7.1 |
| 2021-04-08 | CVE-2021-29154 | Command Injection vulnerability in multiple products BPF JIT compilers in the Linux kernel through 5.11.12 have incorrect computation of branch displacements, allowing them to execute arbitrary code within the kernel context. | 7.8 |
| 2021-03-26 | CVE-2020-35508 | Improper Initialization vulnerability in multiple products A flaw possibility of race condition and incorrect initialization of the process id was found in the Linux kernel child/parent process identification handling while filtering signal handlers. | 4.5 |
| 2021-03-22 | CVE-2021-28971 | Improper Handling of Exceptional Conditions vulnerability in multiple products In intel_pmu_drain_pebs_nhm in arch/x86/events/intel/ds.c in the Linux kernel through 5.11.8 on some Haswell CPUs, userspace applications (such as perf-fuzzer) can cause a system crash because the PEBS status in a PEBS record is mishandled, aka CID-d88d05a9e0b6. | 5.5 |
