FreeBSD -- TOCTOU race in POSIX shared memory large page configuration

Problem Description: The FIOSSHMLPGCNF ioctl2 operation configures the page size for a largepage shared memory object. This is intended to be used immediately after creating the object, before any memory is allocated for the object. The handler checked whether a page size had already been...

The vulnerability of the xe_vm_madvise_ioctl() function in the drivers/gpu/drm/xe/xe_vm_madvise.c module of the Direct Rendering Infrastructure (DRI) driver for the Linux operating system allows a attacker to cause a service failure.

The vulnerability of the xevmmadviseioctl function in the drivers/gpu/drm/xe/xevmmadvise.c module of the Direct Rendering Infrastructure DRI driver for the Linux operating system is related to improper memory release memory leak. Exploiting this vulnerability can allow an attacker to cause a...

Vulnerability of functions __ext4_iget() (fs/ext4/inode.c) and swap_inode_boot_loader() (fs/ext4/ioctl.c) in the Ext4 file system of the Linux operating system, which allows a hacker to trigger a service failure

The vulnerability of the ext4iget function fs/ext4/inode.c and the swapinodebootloader function fs/ext4/ioctl.c in the Ext4 file system of the Linux operating system is related to insufficient handling of exceptional conditions. Exploiting this vulnerability can allow an attacker to cause a servi...

FreeBSD -- Kernel use-after-free via tty ioctls

Problem Description: The TIOCSCTTY ioctl handler drops the tty lock in order to acquire the process tree lock. After reacquiring the tty lock, the handler did not revalidate the state of the terminal, and could proceed to link a terminal that was concurrently being destroyed to the calling proces...

FreeBSD -- Kernel use-after-free via the SNDCTL_DSP_SYNCSTART ioctl

Problem Description: The implementation of this ioctl attempts to acquire locks on all channels in a sync group. If locking a channel would block, it releases the sync group list lock and sleeps. Upon reawakening, it is possible that the sync group structure is freed, but the implementation did n...
