CVE-2026-58094: Time-of-check Time-of-use (TOCTOU) Race Condition

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 configured without holding t...

Denial Of Service (DoS)

kernel is vulnerable to denial of service DoS.Lack of validation in getrawsocket in drivers/vhost/net.c of an skfamily field allows to attacker perform ioctl2 calls on the '/dev/vhost-net' device may use this flaw to crash the kernel...

CVE-2019-7303 Snapd seccomp filter TIOCSTI ioctl bypass

A vulnerability in the seccomp filters of Canonical snapd before version 2.37.4 allows a strict mode snap to insert characters into a terminal on a 64-bit host. The seccomp rules were generated to match 64-bit ioctl2 commands on a 64-bit platform; however, the Linux kernel only uses the lower 32...

FreeBSD -- Insufficient credential checks in network ioctl(2)

Problem Description: As is commonly the case, the IPv6 and ATM network layer ioctl request handlers are written in such a way that an unrecognized request is passed on unmodified to the link layer, which will either handle it or return an error code. Network interface drivers, however, assume tha...
