| CVE-2020-25673 | Med | 0.36 | 5.5 | 0.00 | May 26, 2021 | A vulnerability was found in Linux kernel where non-blocking socket in llcp_sock_connect() leads to leak and eventually hanging-up the system. | ||
| CVE-2020-27830 | Med | 0.36 | 5.5 | 0.00 | May 13, 2021 | 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. | ||
| CVE-2020-26147 | Med | 0.36 | 5.4 | 0.08 | May 11, 2021 | An issue was discovered in the Linux kernel 5.8.9.
