CVE-2026-58086

As an inadvertent side effect of an unrelated code change, PRIVKTRACE was always denied to a jailed root user. Tracing configured by a jailed root user was therefore not flagged as privileged. An unprivileged user in a jail that has permission to debug the target process can modify the jailed roo...

EUVD-2026-62365

The ELF core dump code counted the number of dumpable VM map entries, allocated a buffer for the corresponding program headers, then iterated over the map a second time to populate them. A process sharing the address space via rfork2 can mutate the map between the two passes, causing the second...

CVE-2026-58086

FreeBSD 15.0 and 15.1 are affected by a privilege validation flaw in the ktrace(2) facility within jails. Due to an unrelated code change, PRIV_KTRACE was always denied to a jailed root user, so tracing they configured was not flagged as privileged. As a result, an unprivileged user in the same j...

CVE-2026-58086 ktrace(2) privilege incorrectly validated in jails

As an inadvertent side effect of an unrelated code change, PRIVKTRACE was always denied to a jailed root user. Tracing configured by a jailed root user was therefore not flagged as privileged.

EUVD-2026-62339

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...

CVE-2026-49427

Pages belonging to largepage shared memory objects were not explicitly wired. When sendfile2 transmitted such an object with the SFNOCACHE flag, it freed the underlying pages after transmission even though existing mappings still referred to them. An unprivileged local user can abuse the bug to...

CVE-2026-49419

When the JAILATDESC flag is specified, kernjailset and kernjailget released the reference to the caller's current prison before looking up the jail descriptor. If the descriptor lookup failed, error-handling paths released the same reference a second time. An unprivileged local user can trigger a...

CVE-2026-49419

FreeBSD 15.0+ kernel contains a double-free bug in kern_jail_set() and kern_jail_get(): when the JAIL_AT_DESC flag is used, the caller's current prison reference is released before descriptor lookup, then released again on error paths. An unprivileged local user can trigger a prison reference cou...
