FreeBSD -- Unauthorized credential switching

Problem Description: In FreeBSD 15.0, the kernel structure used to represent user credentials changed: previously the primary group ID was stored in the first element of the array containing the list of supplementary group IDs, whereas now the primary group ID is stored in a dedicated field. This...

FreeBSD -- Use-after-free in unix SOCK_STREAM message handling

Problem Description: The SOCKSTREAM receive path in the unix socket implementation failed to fully detach control messages from the socket buffer before processing them. Some error paths would free those messages, leaving freed data mbufs in the receive socket buffer. Impact: An unprivileged loca...

FreeBSD -- hwpmc fails to detach PMCs during exec credential transitions

Problem Description: When a process calls execve2 to execute a setuid or setgid image, hwpmc4 is supposed to detach PMCs owned by unprivileged processes. An inverted check meant that this scenario was not handled properly. Impact: An unprivileged local user who has attached PMCs to a process can...

FreeBSD -- Multiple vulnerabilities in ppp(8)

Problem Description: ppp8 contained three memory safety errors in its handling of multilink endpoint discriminator options. mpEnddisc used incorrect length calculations when formatting endpoint discriminator addresses for display, allowing a received endpoint option to overflow a global result...

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...

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...

Astra Linux – Vulnerability in Linux

A issue was discovered in Xen through version 4.14.x. Some operating systems, such as Linux, FreeBSD, and NetBSD, process watch events using a single thread. If these events are received faster than the thread can handle them, they will be queued up. Since the queue is unbounded, a guest system m...

CVE-2026-58083

While the kernel was copying knotes during fork, a knote with a timer-based filter could fire and be enqueued on the kqueue's active list before the copy was complete. The copy routine did not account for this and could enqueue the new knote a second time, corrupting the active list. In addition,...

CVE-2026-58085

After dispatching a decrypt operation to OCF and receiving the result, the wg4 driver failed to check whether the MAC verification step succeeded. The driver thus silently accepted packets with an invalid Poly1305 authentication tag. A remote attacker who can send UDP packets to a WireGuard...
