| CVE-2022-0847 | HIGH 7.8 | fedoraproject fedora A flaw was found in the way the "flags" member of the new pipe buffer structure was lacking proper initialization in copy_page_to_iter_pipe and push_pipe functions in the Linux kernel and could thus contain stale values. An unprivileged local user could use th | 88.6% | |
| CVE-2016-5195 | HIGH 7.0 | canonical ubuntu_linux Race condition in mm/gup.c in the Linux kernel 2.x through 4.x before 4.8.3 allows local users to gain privileges by leveraging incorrect handling of a copy-on-write (COW) feature to write to a read-only memory mapping, as exploited in the wild in October 2016 | 83.5% | |
| CVE-2021-22555 | HIGH 8.3 | brocade fabric_operating_system A heap out-of-bounds write affecting Linux since v2.6.19-rc1 was discovered in net/netfilter/x_tables.c. This allows an attacker to gain privileges or cause a DoS (via heap memory corruption) through user name space | 78.7% | |
| CVE-1999-0128 | MED 5.0 | digital osf_1 Oversized ICMP ping packets can result in a denial of service, aka Ping o' Death. | 74.7% | — |
| CVE-2018-5390 | HIGH 7.5 | a10networks advanced_core_operating_system Linux kernel versions 4.9+ can be forced to make very expensive calls to tcp_collapse_ofo_queue() and tcp_prune_ofo_queue() for every incoming packet which can lead to a denial of service. | 73.7% | — |
| CVE-2003-0001 | MED 5.0 | freebsd freebsd Multiple ethernet Network Interface Card (NIC) device drivers do not pad frames with null bytes, which allows remote attackers to obtain information from previous packets or kernel memory by using malformed packets, as demonstrated by Etherleak. | 72.5% | — |
| CVE-2023-0210 | HIGH 7.5 | linux linux_kernel A bug affects the Linux kernel’s ksmbd NTLMv2 authentication and is known to crash the OS immediately in Linux-based systems. | 71.7% | — |
| CVE-1999-0513 | MED 5.0 | digital unix ICMP messages to broadcast addresses are allowed, allowing for a Smurf attack that can cause a denial of service. | 70.5% | — |
| CVE-2022-0435 | HIGH 8.8 | fedoraproject fedora A stack overflow flaw was found in the Linux kernel's TIPC protocol functionality in the way a user sends a packet with malicious content where the number of domain member nodes is higher than the 64 allowed.
