| CVE-2017-7616 | 2 Linux, Redhat | 3 Linux Kernel, Enterprise Linux, Rhel Extras Rt | 2025-04-20 | N/A |
| Incorrect error handling in the set_mempolicy and mbind compat syscalls in mm/mempolicy.c in the Linux kernel through 4.10.9 allows local users to obtain sensitive information from uninitialized stack data by triggering failure of a certain bitmap operation. | ||||
| CVE-2017-17805 | 7 Canonical, Debian, Linux and 4 more | 10 Ubuntu Linux, Debian Linux, Linux Kernel and 7 more | 2025-04-20 | 7.8 High |
| The Salsa20 encryption algorithm in the Linux kernel before 4.14.8 does not correctly handle zero-length inputs, allowing a local attacker able to use the AF_ALG-based skcipher interface (CONFIG_CRYPTO_USER_API_SKCIPHER) to cause a denial of service (uninitialized-memory free and kernel crash) or have unspecified other impact by executing a crafted sequence of system calls that use the blkcipher_walk API. Both the generic implementation (crypto/salsa20_generic.c) and x86 implementation (arch/x86/crypto/salsa20_glue.c) of Salsa20 were vulnerable. | ||||
| CVE-2017-1000111 | 3 Debian, Linux, Redhat | 11 Debian Linux, Linux Kernel, Enterprise Linux and 8 more | 2025-04-20 | 7.8 High |
| Linux kernel: heap out-of-bounds in AF_PACKET sockets. This new issue is analogous to previously disclosed CVE-2016-8655. In both cases, a socket option that changes socket state may race with safety checks in packet_set_ring. Previously with PACKET_VERSION. This time with PACKET_RESERVE. The solution is similar: lock the socket for the update. This issue may be exploitable, we did not investigate further. As this issue affects PF_PACKET sockets, it requires CAP_NET_RAW in the process namespace. But note that with user namespaces enabled, any process can create a namespace in which it has CAP_NET_RAW. | ||||
| CVE-2017-1000410 | 3 Debian, Linux, Redhat | 13 Debian Linux, Linux Kernel, Enterprise Linux and 10 more | 2025-04-20 | N/A |
| The Linux kernel version 3.3-rc1 and later is affected by a vulnerability lies in the processing of incoming L2CAP commands - ConfigRequest, and ConfigResponse messages. This info leak is a result of uninitialized stack variables that may be returned to an attacker in their uninitialized state. By manipulating the code flows that precede the handling of these configuration messages, an attacker can also gain some control over which data will be held in the uninitialized stack variables. This can allow him to bypass KASLR, and stack canaries protection - as both pointers and stack canaries may be leaked in this manner. Combining this vulnerability (for example) with the previously disclosed RCE vulnerability in L2CAP configuration parsing (CVE-2017-1000251) may allow an attacker to exploit the RCE against kernels which were built with the above mitigations. These are the specifics of this vulnerability: In the function l2cap_parse_conf_rsp and in the function l2cap_parse_conf_req the following variable is declared without initialization: struct l2cap_conf_efs efs; In addition, when parsing input configuration parameters in both of these functions, the switch case for handling EFS elements may skip the memcpy call that will write to the efs variable: ... case L2CAP_CONF_EFS: if (olen == sizeof(efs)) memcpy(&efs, (void *)val, olen); ... The olen in the above if is attacker controlled, and regardless of that if, in both of these functions the efs variable would eventually be added to the outgoing configuration request that is being built: l2cap_add_conf_opt(&ptr, L2CAP_CONF_EFS, sizeof(efs), (unsigned long) &efs); So by sending a configuration request, or response, that contains an L2CAP_CONF_EFS element, but with an element length that is not sizeof(efs) - the memcpy to the uninitialized efs variable can be avoided, and the uninitialized variable would be returned to the attacker (16 bytes). | ||||
| CVE-2017-10661 | 3 Debian, Linux, Redhat | 12 Debian Linux, Linux Kernel, Enterprise Linux and 9 more | 2025-04-20 | 7.0 High |
| Race condition in fs/timerfd.c in the Linux kernel before 4.10.15 allows local users to gain privileges or cause a denial of service (list corruption or use-after-free) via simultaneous file-descriptor operations that leverage improper might_cancel queueing. | ||||
| CVE-2017-14140 | 2 Linux, Redhat | 3 Linux Kernel, Enterprise Linux, Rhel Extras Rt | 2025-04-20 | N/A |
| The move_pages system call in mm/migrate.c in the Linux kernel before 4.12.9 doesn't check the effective uid of the target process, enabling a local attacker to learn the memory layout of a setuid executable despite ASLR. | ||||
| CVE-2017-1000252 | 2 Linux, Redhat | 4 Linux Kernel, Enterprise Linux, Rhel Eus and 1 more | 2025-04-20 | N/A |
| The KVM subsystem in the Linux kernel through 4.13.3 allows guest OS users to cause a denial of service (assertion failure, and hypervisor hang or crash) via an out-of bounds guest_irq value, related to arch/x86/kvm/vmx.c and virt/kvm/eventfd.c. | ||||
| CVE-2017-1000112 | 2 Linux, Redhat | 8 Linux Kernel, Enterprise Linux, Enterprise Mrg and 5 more | 2025-04-20 | 7.0 High |
| Linux kernel: Exploitable memory corruption due to UFO to non-UFO path switch. When building a UFO packet with MSG_MORE __ip_append_data() calls ip_ufo_append_data() to append. However in between two send() calls, the append path can be switched from UFO to non-UFO one, which leads to a memory corruption. In case UFO packet lengths exceeds MTU, copy = maxfraglen - skb->len becomes negative on the non-UFO path and the branch to allocate new skb is taken. This triggers fragmentation and computation of fraggap = skb_prev->len - maxfraglen. Fraggap can exceed MTU, causing copy = datalen - transhdrlen - fraggap to become negative. Subsequently skb_copy_and_csum_bits() writes out-of-bounds. A similar issue is present in IPv6 code. The bug was introduced in e89e9cf539a2 ("[IPv4/IPv6]: UFO Scatter-gather approach") on Oct 18 2005. | ||||
| CVE-2016-8399 | 2 Linux, Redhat | 4 Linux Kernel, Enterprise Linux, Rhel Eus and 1 more | 2025-04-20 | 7.0 High |
| An elevation of privilege vulnerability in the kernel networking subsystem could enable a local malicious application to execute arbitrary code within the context of the kernel.

| CVE-2017-12192 | 2 Linux, Redhat | 4 Linux Kernel, Enterprise Linux, Enterprise Mrg and 1 more | 2025-04-20 | N/A |
| The keyctl_read_key function in security/keys/keyctl.c in the Key Management subcomponent in the Linux kernel before 4.13.5 does not properly consider that a key may be possessed but negatively instantiated, which allows local users to cause a denial of service (OOPS and system crash) via a crafted KEYCTL_READ operation. | ||||
| CVE-2017-7184 | 3 Canonical, Linux, Redhat | 8 Ubuntu Linux, Linux Kernel, Enterprise Linux and 5 more | 2025-04-20 | 7.8 High |
| The xfrm_replay_verify_len function in net/xfrm/xfrm_user.c in the Linux kernel through 4.10.6 does not validate certain size data after an XFRM_MSG_NEWAE update, which allows local users to obtain root privileges or cause a denial of service (heap-based out-of-bounds access) by leveraging the CAP_NET_ADMIN capability, as demonstrated during a Pwn2Own competition at CanSecWest 2017 for the Ubuntu 16.10 linux-image-* package 4.8.0.41.52. | ||||
| CVE-2017-6214 | 2 Linux, Redhat | 4 Linux Kernel, Enterprise Linux, Enterprise Mrg and 1 more | 2025-04-20 | N/A |
| The tcp_splice_read function in net/ipv4/tcp.c in the Linux kernel before 4.9.11 allows remote attackers to cause a denial of service (infinite loop and soft lockup) via vectors involving a TCP packet with the URG flag. | ||||
| CVE-2017-9074 | 2 Linux, Redhat | 4 Linux Kernel, Enterprise Linux, Enterprise Mrg and 1 more | 2025-04-20 | 7.8 High |
| The IPv6 fragmentation implementation in the Linux kernel through 4.11.1 does not consider that the nexthdr field may be associated with an invalid option, which allows local users to cause a denial of service (out-of-bounds read and BUG) or possibly have unspecified other impact via crafted socket and send system calls. | ||||
| CVE-2017-12190 | 2 Linux, Redhat | 5 Linux Kernel, Enterprise Linux, Enterprise Mrg and 2 more | 2025-04-20 | N/A |
| The bio_map_user_iov and bio_unmap_user functions in block/bio.c in the Linux kernel before 4.13.8 do unbalanced refcounting when a SCSI I/O vector has small consecutive buffers belonging to the same page. The bio_add_pc_page function merges them into one, but the page reference is never dropped. This causes a memory leak and possible system lockup (exploitable against the host OS by a guest OS user, if a SCSI disk is passed through to a virtual machine) due to an out-of-memory condition. | ||||
| CVE-2017-6951 | 2 Linux, Redhat | 4 Linux Kernel, Enterprise Linux, Enterprise Mrg and 1 more | 2025-04-20 | N/A |
| The keyring_search_aux function in security/keys/keyring.c in the Linux kernel through 3.14.79 allows local users to cause a denial of service (NULL pointer dereference and OOPS) via a request_key system call for the "dead" type. | ||||
