A race condition vulnerability was found in packetsetring that can lead to use after free on a function pointer. This vulnerability can be used to gain kernel code execution for the local attacker capable of creating AFPACKET sockets. This issue was introduced with following commit:
https://github.com/torvalds/linux/commit/f6fb8f100b807378fda19e83e5ac6828b638603a
A vulnerability was found in the Linux kernel. Payloads of NM entries are not supposed to contain NUL. When such entry is processed, only the part prior to the first NUL goes into the concatenation (i.e. the directory entry name being encoded by a bunch of NM entries). The process stops when the amount collected so far + the claimed amount in the current NM entry exceed 254.
However, the value returned as the total length is the sum of claimed sizes, not the actual amount collected. And that can grow pretty large - not unlimited, since you'd need to put CE entries in between to be able to get more than the maximum that could be contained in one isofs directory entry / continuation chunk and the process stops once it had encountered 32 CEs, but you can get about 8Kb easily. And that's what will be passed to readdir callback as the name length. 8Kb copytouser() from a buffer allocated by getfreepage()

A flaw in the Linux kernels implementation of the ath10k USB device driver could allow an attacker with the ability to plug in custom-crafted hardware to create a null pointer dereference via an incomplete address in an endpoint descriptor.
This will crash the system.

crypto/pcrypt.c in the Linux kernel before 4.14.13 mishandles freeing instances, allowing a local user able to access the AFALG-based AEAD interface (CONFIGCRYPTOUSERAPIAEAD) and pcrypt (CONFIGCRYPTOPCRYPT) to cause a denial of service (kfree of an incorrect pointer) or possibly have unspecified other impact by executing a crafted sequence of system calls.
ImageMagick 7.0.8-50 Q16 has a stack-based buffer overflow at coders/pnm.c in WritePNMImage because of off-by-one errors.
An integer overflow vulnerability was found in xtalloctableinfo, which on 32-bit systems can lead to small structure allocation and a copyfromuser based heap corruption.

It was reported that due to buffer overflow, it is possible for remote TCP endpoint to trigger the opposite TCP endpoint to write to a socket in sequence which causes the ethernet driver to send arbitrary kernel data over the ethernet interface instead of a portion of the intended packet data.
Initially this issue was believed to be present in a number of mainline drivers in 3.10.x and 4.4.2 vanilla kernel sources. After further investigation it was found that only [atl2] driver (code in drivers/net/ethernet/atheros/atlx/atl2.c) from the list of suspected drivers is vulnerable.
As a result, certain conditions should be met to trigger the issue: - the [atl2] driver and the corresponding network card (which believed to be not so frequently used) should be present on the target system - an application should make such a sequence of calls that a network buffer for the data to be transmitted is scattered - hardware checksumming should be enabled so the packet checksum is correct
The above makes this vulnerability less probable to be hit.
It was discovered that the glibc DNS resolver dereferenced a NULL pointer when processing a specific, but valid resource record type.

ImageMagick version 7.0.7-2 contains a memory leak in ReadYUVImage in coders/yuv.c.
A cache-related side channel was found in nettle's RSA and DSA decryption code. An attacker could use this flaw to recover the private key, from a co-located virtual-machine instance.
