SUSE CVE-2013-4738

Multiple stack-based buffer overflows in the MSM camera driver for the Linux kernel 3.x, as used in Qualcomm Innovation Center QuIC Android contributions for MSM devices and other products, allow attackers to gain privileges via 1 a crafted VIDIOCMSMVPEDEQUEUESTREAMBUFFINFO ioctl call, related to...

SUSE CVE-2013-6382

Multiple buffer underflows in the XFS implementation in the Linux kernel through 3.12.1 allow local users to cause a denial of service memory corruption or possibly have unspecified other impact by leveraging the CAPSYSADMIN capability for a 1 XFSIOCATTRLISTBYHANDLE or 2 XFSIOCATTRLISTBYHANDLE32...

SUSE CVE-2016-10150

Use-after-free vulnerability in the kvmioctlcreatedevice function in virt/kvm/kvmmain.c in the Linux kernel before 4.8.13 allows host OS users to cause a denial of service host OS crash or possibly gain privileges via crafted ioctl calls on the /dev/kvm device...

SUSE CVE-2018-6412

In the function sbusfbioctlhelper in drivers/video/fbdev/sbuslib.c in the Linux kernel through 4.15, an integer signedness error allows arbitrary information leakage for the FBIOPUTCMAPSPARC and FBIOGETCMAPSPARC commands...

SUSE CVE-2019-14284

In the Linux kernel before 5.2.3, drivers/block/floppy.c allows a denial of service by setupformatparams division-by-zero. Two consecutive ioctls can trigger the bug: the first one should set the drive geometry with .sect and .rate values that make FSECTPERTRACK be zero. Next, the floppy format...

SUSE CVE-2023-0615

A memory leak flaw and potential divide by zero and Integer overflow was found in the Linux kernel V4L2 and vivid test code functionality. This issue occurs when a user triggers ioctls, such as VIDIOCSDVTIMINGS ioctl. This could allow a local user to crash the system if vivid test code enabled...

kernel: race condition in snd_pcm_hw_free leading to use-after-free

A use-after-free flaw was found in the Linux kernel’s sound subsystem in the way a user triggers concurrent calls of PCM hwparams. The hwfree ioctls or similar race condition happens inside ALSA PCM for other ioctls. This flaw allows a local user to crash or potentially escalate their privileges ...

kernel: dm ioctl: prevent potential spectre v1 gadget

A vulnerability was found in the Linux kernel's dm-ioctl interface in the lookupioctl function, which accepts a user-provided cmd value that is used to index the ioctls array directly. This issue could lead to an out-of-bounds access if the CPU speculatively executes the array access before cmd i...
