|---|---|---|---|---|---|---|---|---|
| CVE-2020-36516 | Med | 0.38 | 5.9 | 0.01 | Feb 26, 2022 | An issue was discovered in the Linux kernel through 5.16.11. The mixed IPID assignment method with the hash-based IPID assignment policy allows an off-path attacker to inject data into a victim's TCP session or terminate that session. | ||
| CVE-2020-8649 | Med | 0.38 | 5.9 | 0.00 | Feb 6, 2020 | There is a use-after-free vulnerability in the Linux kernel through 5.5.2 in the vgacon_invert_region function in drivers/video/console/vgacon.c. | ||
| CVE-2007-4774 | Med | 0.38 | 5.9 | 0.02 | Jan 15, 2020 | The Linux kernel before 2.4.36-rc1 has a race condition. It was possible to bypass systrace policies by flooding the ptraced process with SIGCONT signals, which can can wake up a PTRACED process. | ||
