kernel: race condition in snd_seq_write() may lead to UAF or OOB-access

ALSA sequencer core initializes the event pool on demand by invoking sndseqpoolinit when the first write happens and the pool is empty. A user can reset the pool size manually via ioctl concurrently, and this may lead to UAF or out-of-bound access...

Name of the Vulnerable Software and Affected Versions: Linux kernel versions through 5.1.5 Description: An issue was discovered in the MPT3COMMAND case in ctl ioctl main in drivers/scsi/mpt3sas/mpt3sas ctl.c. It allows local users to cause a denial of service or possibly have unspecified other...

CVE-2019-10142

A flaw was found in the Linux kernel's freescale hypervisor manager implementation, kernel versions 5.0.x up to, excluding 5.0.17. A parameter passed to an ioctl was incorrectly validated and used in size calculations for the page size calculation. An attacker can use this flaw to crash the syste...

Apple macOS < 10.14.5 / iOS < 12.3 XNU - Wild-read due to bad cast in stf_ioctl

/ Reproduction Tested on macOS 10.14.3: $ clang -o stfwildread stfwildread.cc $ ./stfwildread Explanation SIOCSIFADDR is an ioctl that sets the address of an interface. The stf interface ioctls are handled by the stfioctl function. The crash occurs in the following case where a struct ifreq is re...

CVE-2018-7191

In the tun subsystem in the Linux kernel before 4.13.14, devgetvalidname is not called before registernetdevice. This allows local users to cause a denial of service NULL pointer dereference and panic via an ioctlTUNSETIFF call with a dev name containing a / character. This is similar to...

Null pointer dereference

CVE-2018-7191

CVE-2018-7191 affects the Linux kernel tun subsystem prior to 4.13.14. Root cause: dev_get_valid_name is not called before register_netdevice, enabling a local user to trigger a NULL pointer dereference via ioctl(TUNSETIFF) with a device name containing a “/” character, potentially causing a deni...

Memory Corruption

Linux kernel is vulnerable to memory corruption vulnerability. This is because the ALSA sequencer core initializes the event pool on demand by invoking sndseqpoolinit when the first write happens and the pool is empty. A user can reset the pool size manually via ioctl concurrently causing an...
