| CVE-2023-31082 | MED 5.5 | linux linux_kernel An issue was discovered in drivers/tty/n_gsm.c in the Linux kernel 6.2. There is a sleeping function called from an invalid context in gsmld_write, which will block the kernel. Note: This has been disputed by 3rd parties as not a valid vulnerability. | 0.4% | — |
| CVE-2020-29368 | HIGH 7.0 | linux linux_kernel An issue was discovered in __split_huge_pmd in mm/huge_memory.c in the Linux kernel before 5.7.5. The copy-on-write implementation can grant unintended write access because of a race condition in a THP mapcount check, aka CID-c444eb564fb1. | 0.4% | — |
| CVE-2018-16882 | HIGH 8.8 | canonical ubuntu_linux A use-after-free issue was found in the way the Linux kernel's KVM hypervisor processed posted interrupts when nested(=1) virtualization is enabled. In nested_get_vmcs12_pages(), in case of an error while processing posted interrupt address, it unmaps the 'pi_ | 0.4% | — |
