kernel: MIDI driver race condition leads to a double-free

It was found that the raw midi kernel driver does not protect against concurrent access which leads to a double realloc double free in sndrawmidiinputparams and sndrawmidioutputstatus which are part of sndrawmidiioctl handler in rawmidi.c file. A malicious local attacker could possibly use this f...

Design/Logic Flaw

The LHA.sys driver before 1.1.1811.2101 in LG Device Manager exposes functionality that allows low-privileged users to read and write arbitrary physical memory via specially crafted IOCTL requests and elevate system privileges. This occurs because the device object has an associated symbolic link...

CVE-2019-8372

CVE-2019-8372 affects the LHA.sys driver in LG Device Manager (versions prior to 1.1.1811.2101). The root cause is that the device object has a symbolic link and an open DACL, enabling low-privileged users to read/write arbitrary physical memory via specially crafted IOCTL requests, thereby eleva...

Denial Of Service (DoS)

Linux kernel is vulnerable to denial of service. Local users are able to exploit a race condition in the ALSA subsystem to crash the application via malicious /dev/snd/seq ioctl calls. The crash is a result of a use-after-free UAF bug in sndseqioctlcreateport...

Authorization Bypass

Linux kernel-rt is vulnerable to authorization bypass. The default SCSI command filter block/scsiioctl.c does not accommodate commands that overlap across device classes, allowing local users to bypass intended access restrictions to write arbitrary data to a read-only LUN via an SGIO ioctl call...
