CVE-2019-7303 is a high-severity vulnerability affecting Canonical snapd versions prior to 2.37.4, where a flaw in seccomp filters allows a strict mode snap to inject characters into a terminal on 64-bit Linux hosts. This issue arises because the seccomp rules were incorrectly generated for 64-bit ioctl(2) commands, while the kernel only uses the lower 32 bits. With a CVSS score of 7.5, the vulnerability has a network attack vector and low attack complexity, potentially leading to high integrity impact. While not observed in active exploitation and not listed on the KEV catalog, a public exploit (EDB-46594) exists, though there is minimal community discussion or media coverage surrounding this CVE.
