CVE-2021-43267 | 3 Fedoraproject, Linux, Netapp | 16 Fedora, Linux Kernel, H300e and 13 more | 2023-11-07 | 7.5 HIGH | 9.8 CRITICAL |
An issue was discovered in net/tipc/crypto.c in the Linux kernel before 5.14.16. The Transparent Inter-Process Communication (TIPC) functionality allows remote attackers to exploit insufficient validation of user-supplied sizes for the MSG_CRYPTO message type. | |||||
CVE-2021-3506 | 3 Debian, Linux, Netapp | 20 Debian Linux, Linux Kernel, Cloud Backup and 17 more | 2023-11-07 | 5.6 MEDIUM | 7.1 HIGH |
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. A bounds check failure allows a local attacker to gain access to out-of-bounds memory leading to a system crash or a leak of internal kernel information. The highest threat from this vulnerability is to system availability. | |||||

CVE-2021-25219 | 6 Debian, Fedoraproject, Isc and 3 more | 23 Debian Linux, Fedora, Bind and 20 more | 2023-11-07 | 5.0 MEDIUM | 5.3 MEDIUM |
In BIND 9.3.0 -> 9.11.35, 9.12.0 -> 9.16.21, and versions 9.9.3-S1 -> 9.11.35-S1 and 9.16.8-S1 -> 9.16.21-S1 of BIND Supported Preview Edition, as well as release versions 9.17.0 -> 9.17.18 of the BIND 9.17 development branch, exploitation of broken authoritative servers using a flaw in response processing can cause degradation in BIND resolver performance. The way the lame cache is currently designed makes it possible for its internal data structures to grow almost infinitely, which may cause significant delays in client query processing. | |||||
CVE-2021-25215 | 6 Debian, Fedoraproject, Isc and 3 more | 25 Debian Linux, Fedora, Bind and 22 more | 2023-11-07 | 5.0 MEDIUM | 7.5 HIGH |

CVE-2021-23133 | 5 Broadcom, Debian, Fedoraproject and 2 more | 24 Brocade Fabric Operating System, Debian Linux, Fedora and 21 more | 2023-11-07 | 6.9 MEDIUM | 7.0 HIGH |
A race condition in Linux kernel SCTP sockets (net/sctp/socket.c) before 5.12-rc8 can lead to kernel privilege escalation from the context of a network service or an unprivileged process. If sctp_destroy_sock is called without sock_net(sk)->sctp.addr_wq_lock then an element is removed from the auto_asconf_splist list without any proper locking. This can be exploited by an attacker with network service privileges to escalate to root or from the context of an unprivileged user directly if a BPF_CGROUP_INET_SOCK_CREATE is attached which denies creation of some SCTP socket. | |||||
CVE-2020-8835 | 4 Canonical, Fedoraproject, Linux and 1 more | 47 Ubuntu Linux, Fedora, Linux Kernel and 44 more | 2023-11-07 | 7.2 HIGH | 7.8 HIGH |
In the Linux kernel 5.5.0 and newer, the bpf verifier (kernel/bpf/verifier.c) did not properly restrict the register bounds for 32-bit operations, leading to out-of-bounds reads and writes in kernel memory. The vulnerability also affects the Linux 5.4 stable series, starting with v5.4.7, as the introducing commit was backported to that branch. This vulnerability was fixed in 5.6.1, 5.5.14, and 5.4.29. (issue is aka ZDI-CAN-10780) | |||||
CVE-2020-7595 | 7 Canonical, Debian, Fedoraproject and 4 more | 32 Ubuntu Linux, Debian Linux, Fedora and 29 more | 2023-11-07 | 5.0 MEDIUM | 7.5 HIGH |

ntpd in ntp 4.2.8 before 4.2.8p15 and 4.3.x before 4.3.101 allows remote attackers to cause a denial of service (memory consumption) by sending packets, because memory is not freed in situations where a CMAC key is used and associated with a CMAC algorithm in the ntp.keys file. |
