| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 2018-01-12 | CVE-2018-5344 | Use After Free vulnerability in multiple products In the Linux kernel through 4.14.13, drivers/block/loop.c mishandles lo_release serialization, which allows attackers to cause a denial of service (__lock_acquire use-after-free) or possibly have unspecified other impact. | 4.6 |
| 2018-01-11 | CVE-2018-5333 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel through 4.14.13, the rds_cmsg_atomic function in net/rds/rdma.c mishandles cases where page pinning fails or an invalid address is supplied, leading to an rds_atomic_free_op NULL pointer dereference. | 4.9 |
| 2018-01-11 | CVE-2018-5332 | Out-of-bounds Write vulnerability in multiple products In the Linux kernel through 3.2, the rds_message_alloc_sgs() function does not validate a value that is used during DMA page allocation, leading to a heap-based out-of-bounds write (related to the rds_rdma_extra_size function in net/rds/rdma.c). | 7.8 |
| 2017-12-30 | CVE-2017-17975 | Use After Free vulnerability in Linux Kernel Use-after-free in the usbtv_probe function in drivers/media/usb/usbtv/usbtv-core.c in the Linux kernel through 4.14.10 allows attackers to cause a denial of service (system crash) or possibly have unspecified other impact by triggering failure of audio registration, because a kfree of the usbtv data structure occurs during a usbtv_video_free call, but the usbtv_video_fail label's code attempts to both access and free this data structure. | 4.9 |
| 2017-12-27 | CVE-2017-17864 | Information Exposure vulnerability in Linux Kernel kernel/bpf/verifier.c in the Linux kernel through 4.14.8 mishandles states_equal comparisons between the pointer data type and the UNKNOWN_VALUE data type, which allows local users to obtain potentially sensitive address information, aka a "pointer leak." | 2.1 |
| 2017-12-27 | CVE-2017-17862 | Improper Input Validation vulnerability in Linux Kernel 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. | 4.9 |
| 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. | 2.1 |
| 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 Linux Kernel 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. | 2.1 |
