The netfilter subsystem in the linux kerneldid not properly validate passed user register indices.
The marvell wifi-ex usb device driverin the linux kernel did not properly handle some error conditions.
The f2fs file system implementation in thelinux kernel did not properly validate inode types while performing garbagecollection.
The udf file system implementation in the linuxkernel could attempt to dereference a null pointer in some situations.
The netfilter subsystem in the linux kerneldid not initialize memory in some situations.
The nfs implementation in the linux kernel did notproperly handle requests to open a directory on a regular file.

The yam ax.

A local attackercould use this to cause a denial of service or possibly execute arbitrarycode.
Aphysically proximate attacker could use this to cause a denial of service(system crash).
An attacker could use this to construct a malicious f2fs imagethat, when mounted and operated on, could cause a denial of service (systemcrash).
Anattacker could use this to construct a malicious udf image that, whenmounted and operated on, could cause a denial of service (system crash).
A local attacker could usethis to expose sensitive information (kernel memory).
A localattacker could use this to expose sensitive information (kernel memory).
A local attackercould possibly use this to cause a denial of service (memory exhaustion).
25 device driver in the linux kernel didnot properly deallocate memory in some error conditions.
A local privilegedattacker could use this to cause a denial of service (kernel memoryexhaustion).
