CVE-2026-22078

CVE-2026-22078 concerns O+ Connect where an unauthenticated IPC service allows a local attacker to escalate privileges via the IPC channel. The root cause is lack of client authentication on the IPC interface, enabling external applications to perform sensitive actions with elevated privileges. T...

CVE-2026-22078 O+ Connect's lack of authentication for IPC channels led to a local privilege escalation vulnerability.

Because O+ Connect's IPC service does not authenticate clients, external applications can escalate privileges and perform sensitive actions through the IPC channel...

CVE-2026-49416

The CONSHISTORY ioctl handler did not adequately validate the requested history size. A large value caused an integer overflow in the buffer size calculation, resulting in a heap allocation smaller than expected. Subsequent initialization of the buffer wrote beyond the end of the allocation. An...

CVE-2026-49416

The CVE-2026-49416 issue affects FreeBSD vt(4) CONS_HISTORY: the ioctl handler validates the requested history size, but large values trigger an integer overflow in the buffer size calculation, causing a smaller heap allocation and an out-of-bounds write on initialization. This can enable an unpr...

CVE-2026-49412 Use-after-free bug in the IPV6_MSFILTER socket option handler

The kernel handler for IPV6MSFILTER dropped a serializing lock in order to copy the source-filter list from userspace, then reacquired the lock. During this window another thread could free the multicast filter structure, leaving the handler with a stale pointer to freed memory. An unprivileged...
