| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 2017-12-27 | CVE-2017-17862 | Improper Input Validation vulnerability in multiple products kernel/bpf/verifier.c in the Linux kernel through 4.14.8 ignores unreachable code, even though it would still be processed by JIT compilers. | 5.5 |
| 2017-12-20 | CVE-2017-17807 | Missing Authorization vulnerability in Linux Kernel The KEYS subsystem in the Linux kernel before 4.14.6 omitted an access-control check when adding a key to the current task's "default request-key keyring" via the request_key() system call, allowing a local user to use a sequence of crafted system calls to add keys to a keyring with only Search permission (not Write permission) to that keyring, related to construct_get_dest_keyring() in security/keys/request_key.c. | 3.3 |
| 2017-12-20 | CVE-2017-17806 | Out-of-bounds Write vulnerability in multiple products The HMAC implementation (crypto/hmac.c) in the Linux kernel before 4.14.8 does not validate that the underlying cryptographic hash algorithm is unkeyed, allowing a local attacker able to use the AF_ALG-based hash interface (CONFIG_CRYPTO_USER_API_HASH) and the SHA-3 hash algorithm (CONFIG_CRYPTO_SHA3) to cause a kernel stack buffer overflow by executing a crafted sequence of system calls that encounter a missing SHA-3 initialization. | 7.8 |
| 2017-12-20 | CVE-2017-17805 | Improper Input Validation vulnerability in multiple products 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. | 7.8 |
| 2017-12-18 | CVE-2017-17741 | Out-of-bounds Read vulnerability in multiple products The KVM implementation in the Linux kernel through 4.14.7 allows attackers to obtain potentially sensitive information from kernel memory, aka a write_mmio stack-based out-of-bounds read, related to arch/x86/kvm/x86.c and include/trace/events/kvm.h. | 6.5 |
| 2017-12-12 | CVE-2017-17558 | Out-of-bounds Write vulnerability in multiple products The usb_destroy_configuration function in drivers/usb/core/config.c in the USB core subsystem in the Linux kernel through 4.14.5 does not consider the maximum number of configurations and interfaces before attempting to release resources, which allows local users to cause a denial of service (out-of-bounds write access) or possibly have unspecified other impact via a crafted USB device. | 6.6 |
| 2017-12-07 | CVE-2017-17450 | Missing Authorization vulnerability in Linux Kernel net/netfilter/xt_osf.c in the Linux kernel through 4.14.4 does not require the CAP_NET_ADMIN capability for add_callback and remove_callback operations, which allows local users to bypass intended access restrictions because the xt_osf_fingers data structure is shared across all net namespaces. | 7.8 |
| 2017-12-07 | CVE-2017-17449 | Information Exposure vulnerability in Linux Kernel The __netlink_deliver_tap_skb function in net/netlink/af_netlink.c in the Linux kernel through 4.14.4, when CONFIG_NLMON is enabled, does not restrict observations of Netlink messages to a single net namespace, which allows local users to obtain sensitive information by leveraging the CAP_NET_ADMIN capability to sniff an nlmon interface for all Netlink activity on the system. | 4.7 |
| 2017-12-07 | CVE-2017-17448 | Missing Authorization vulnerability in Linux Kernel net/netfilter/nfnetlink_cthelper.c in the Linux kernel through 4.14.4 does not require the CAP_NET_ADMIN capability for new, get, and del operations, which allows local users to bypass intended access restrictions because the nfnl_cthelper_list data structure is shared across all net namespaces. | 7.8 |
| 2017-12-05 | CVE-2017-8824 | Use After Free vulnerability in Linux Kernel The dccp_disconnect function in net/dccp/proto.c in the Linux kernel through 4.14.3 allows local users to gain privileges or cause a denial of service (use-after-free) via an AF_UNSPEC connect system call during the DCCP_LISTEN state. | 7.8 |
