Privilege escalations (uid=0) 4

The headline result. These findings were not only reproduced — the bug was driven all the way to a root shell as an unprivileged user (or a jail/sandbox escape). Each carries a full exploit chain in its evidence pack. Sorted by CVSS, most severe first (click any column header to re-sort).

ID Sev CVSS Title Impact PoC
DF-2769 High 7.0 Stale unix98 pty master re-open admitted by ptcopen (ptcclose disarms all gates): cross-user session takeover with root command injection when /dev/ptm is exposed by devfs rules
Privilege escalation (general use) · sys/kern/tty_pty.c:585 · pass 2 · new

 uid0 → root reproduced fixed

Reproduced + fix verified 1554

These findings have a working PoC that reproduced the bug, and the proposed fix was then validated the hard way: the patch was applied to a fresh kernel, the kernel rebuilt, and the exact same PoC re-run to confirm the bad behavior is gone (baseline reproduced, patched kernel clean). The fix closes the hole.

ID Sev CVSS Title Impact PoC
DF-2748 High 9.1 Full-duplex journal ack-path loss permanently wedges all writers in uninterruptible, SIGKILL-immune kernel sleep — and mountctl -d frees the journal out from under the sleepers (demonstrated wake-through-reuse UAF)

 dos reproduced fixed
DF-2675 Critical 8.8 allocbuf() maps 17 pages into the 16-page MAXBSIZE per-header KVA slot when (loffset & PAGE_MASK)+size > MAXBSIZE — PTE written into the next buffer header's slot, aliasing one page between two live kernel buffers (cross-buffer R/W, info leak, panic)

Privilege escalation (general use) · sys/kern/kern_systimer.c:360 · pass 2 · new
 panic reproduced fixed
DF-3015 High 8.8 ufs_symlink controlled kernel heap overflow via unvalidated on-disk fs_maxsymlinklen — bcopy of up to 1023 attacker bytes into the 60-byte i_shortlink, ~919 bytes past the struct inode slab chunk

 panic reproduced fixed
DF-3003 High 8.2 hammer_update_itimes() in-place atime/mtime update writes past the inode record's 16KB block on crafted HAMMER1 images — no data_len validation at extraction and hammer_crc_test_leaf() accepts any wrong-length INODE record via the 0-return CRC bypass
Kernel memory corruption (UAF / OOB write) · sys/vfs/hammer/hammer_inode.c:1446 · pass 2 · new

DF-2875 High 8.0 Pipelined BLK_WRITE in one transaction: single-slot iost->data aux tracking frees the most-recent aux while its bio is still in flight (deterministic UAF on bp->b_data) and leaks all earlier aux
Kernel memory corruption (UAF / OOB write) · sys/kern/subr_diskiocom.c:440 · pass 2 · new

DF-2687 High 7.9 TIOCSCTTY reassignment orphans the old tty's t_session, yielding an unprivileged use-after-free of struct session (deterministic panic; ctty hijack of recycled sessions)
Kernel memory corruption (UAF / OOB write) · sys/kern/tty.c:1190 · pass 2 · new

DF-2950 Medium 7.9 Jailed uid-0 passes the sysctl write gate and can write every host-global RW MIB defined here — kern.securelevel raised irreversibly from inside a jail (host root gets EPERM lowering it), plus kern.hostid/domainname/bootfile/maxprocperuid/maxposixlocksperuid/tls_extra corruption; CTLFLAG_PRISON is dead
Privilege escalation (general use) · sys/kern/kern_mib.c:142 · pass 2 · new

DF-2691 High 7.8 EVFILT_SIGNAL knote use-after-free: knote stays linked into struct proc after the target is reaped; kqueue teardown runs SLIST_REMOVE on freed kernel memory
Kernel memory corruption (UAF / OOB write) · sys/kern/kern_sig.c:2667 · pass 2 · new
 panic reproduced fixed
DF-2747 High 7.8 Journal memfifo reservation protocol is not MP-safe: concurrent VOPs on a journaled mount overlap reservations and corrupt the raw record chain (unprivileged reproducible panic; release-kernel OOB-read/livelock)
Base system — kernel core (kern) · sys/kern/vfs_journal.c:527 · pass 2 · new

DF-2815 Medium 7.8 Unserialized global dumper: set_dumper() EBUSY-check TOCTOU / torn struct copy, and clear-or-swap landing during an active dumpsys() → NULL di->priv dereferenced by dev_ddump() (kernel page fault while dumping) and torn-geometry dump misdirection to the wrong device
Privilege escalation (general use) · sys/kern/kern_shutdown.c:948 · pass 2 · new
 panic reproduced fixed
DF-3017 High 7.7 devfs node/cdev lifetime hole: nresolve→devfs_allocv drops devfs_lock on a raw devfs_node; concurrent unpriv pty teardown frees node+cdev → UAF write + sysref_get on freed cdev (proven panic 2/2)
Kernel memory corruption (UAF / OOB write) · sys/vfs/devfs/devfs_vnops.c:474 · pass 2 · new
 panic reproduced fixed
DF-2902 High 7.6 mbrinit/mbr_extended trust device-reported d_media_blksize — up to 2 GiB synchronous read into a MAXPHYS (128 KB) pbuf: assertion-cast bypass (all kernels) or INVARIANTS panic; proven OOB write with attacker-controlled content/length
Kernel memory corruption (UAF / OOB write) · sys/kern/subr_diskmbr.c:127 · pass 2 · new

DF-2685 High 7.1 mlock()/mlockall()/wiring faults zero-fill non-resident (swapped-out) pages instead of paging them in — silent memory destruction in privileged processes
Base system — virtual memory · sys/vm/vm_fault.c:383 · pass 2 · new
 dos reproduced fixed
DF-2716 High 7.1 nlookup() misclassifies a leaf component followed by a trailing slash as an intermediate directory, dropping NLC_STICKY/NLC_APPENDONLY feedback — sticky-bit and append-only-directory deletion/rename restriction bypass
Privilege escalation (general use) · sys/kern/vfs_nlookup.c:653 · pass 2 · new
 authz_bypass (sticky-bit / append-only-dir deletion+rename restriction bypass; not uid0/panic/leak class) reproduced fixed
DF-2920 High 7.1 Beyond-EOF VM pages retained for the last buffer remain faultable: nvnode_pager_setsize()'s unmap is the only EOF enforcement, so mmap reads/writes past EOF succeed on every filesystem, pre-truncate content (incl. recycled disk-block residue) is served during the truncate zero-fill window, and on tmpfs beyond-EOF writes become file data
Kernel memory corruption (UAF / OOB write) · sys/kern/vfs_vm.c:42 · pass 2 · new
 leak reproduced fixed
DF-2940 High 7.1 mpipe_done() tears down the malloc pipeline with no synchronization against in-flight users — its only teardown caller (dm-crypt) destroys tables while bios still hold mpipe buffers: KKASSERT panic / UAF write on production kernels / reproduced permanent kernel wedge
Kernel memory corruption (UAF / OOB write) · sys/kern/kern_mpipe.c:122 · pass 2 · new

 panic reproduced fixed
DF-2779 High 7.0 mq_send1 re-reads mq_sig_notify.sigev_signo after releasing mq_mtx: concurrent mq_notify re-registration (SIGEV_NONE bypasses signo validation) smuggles an attacker-chosen int into ksignal — panic on INVARIANTS, OOB atomic sigset write on production kernels
Base system — kernel core (kern) · sys/kern/sys_mqueue.c:877 · pass 2 · new

DF-2853 High 7.0 rman_reserve_resource alignment-roundup unsigned wrap grants resources outside the scanned free fragment — overlapping allocations with live owners and free-fragment inflation across neighbors
Kernel memory corruption (UAF / OOB write) · sys/kern/subr_rman.c:247 · pass 2 · new
 dos reproduced fixed
DF-2938 High 7.0 OBJT_DEVICE pager objects never reference the cdev: device teardown while a mapping persists leaves a dangling object->handle → cdev use-after-free in old_dev_pager_fault (indirect call via freed si_ops) and old_dev_pager_dtor (assert + NULL write)
Kernel memory corruption (UAF / OOB write) · sys/vm/device_pager.c:124 · pass 2 · new

DF-2741 High 6.7 DIOCGSLICEINFO: dsioctl bcopy uses runtime dss_nslices (GPT disks: up to 130) against the 16-record ioctl type — 29,184-byte kernel heap OOB write per ioctl

DF-2800 Medium 6.7 prison_priv_check allows SYSCAP_NOSETTIME in jails — jailed uid-0 sets the HOST system clock (settimeofday/clock_settime/adjtime/ntp_adjtime)
Privilege escalation (general use) · sys/kern/kern_jail.c:858 · pass 2 · new
 dos reproduced fixed
DF-2808 Medium 6.7 Cross-segment mapsize under-sizing: mapsize derives only from segs[0]'s start and segs[1]'s end, so segs[0]'s extent is never covered → file-controlled kernel heap overflow (DF-2771 analogue in the EXEC loader)
Kernel memory corruption (UAF / OOB write) · sys/kern/link_elf.c:541 · pass 2 · new
 panic reproduced fixed
DF-2832 Medium 6.7 Syncer-trigger API (trigger_syncer*/speedup_syncer) has no lifetime interlock against vn_syncer_thr_stop — UAF atomic-write on freed syncer ctx (and NULL-ctx / freed-mount reads)
Kernel memory corruption (UAF / OOB write) · sys/kern/vfs_sync.c:561 · pass 2 · new

Kernel memory corruption (UAF / OOB write) · sys/kern/kern_environment.c:580 · pass 2 · new
 panic reproduced fixed
DF-2984 Medium 6.7 syscall_deregister() writes sysent[*offset] through an unvalidated index with an unvalidated value: MOD_LOAD-failure rollback destroys a live syscall slot (EEXIST) → any unprivileged user's syscall(N) is a kernel NULL function call — deterministic persistent panic; EINVAL variant = arbitrary-index 24-byte kernel zero-write; ENFILE variant = sysent[-1] OOB write
Kernel memory corruption (UAF / OOB write) · sys/kern/kern_syscalls.c:72 · pass 2 · new
 panic reproduced fixed
DF-2745 High 6.6 exit1() p_peers unlink race: lost unlink leaves leader permanently wedged in uninterruptible exit (pre-fdfree, pinning fds+vmspace) and members freed while still linked — kernel heap UAF read/write
Kernel memory corruption (UAF / OOB write) · sys/kern/kern_exit.c:384 · pass 2 · new

DF-2898 Medium 6.5 sysent[0]/sysent[198] indirect-syscall gateway dispatches itself: unprivileged one-line syscall(SYS_syscall,0) deterministically panics the kernel (double fault on the kernel-stack guard)
Privilege escalation (general use) · sys/kern/init_sysent.c:17 · pass 2 · new
 panic reproduced fixed
DF-2963 Medium 6.5 GPT entry #127 maps to slice index 128, which dkmakeminor() silently truncates to 7 bits: duplicate major:minor cdevs and s127<->s0 cross-slice data aliasing (reads AND writes)

DF-2621 High 6.3 hammer2_xop_helper_create() re-kmallocs pmp->xop_groups unconditionally — leaked thread array and orphaned threads that use-after-free the pmp
Hammer2 · sys/vfs/hammer2/hammer2_admin.c:431 · pass 2 · new
 dos reproduced fixed
DF-2798 Low 6.3 Out-of-domain free discipline: production kernels silently accept a full-child free beyond bl_blocks (unbounded full-cover branch) and poison parent meta bits to ALL-FREE; the likewise-unbounded direct-allocation path then returns block numbers >= bl_blocks (wild PHYS_TO_VM_PAGE precursor); bl_root allocated without M_ZERO
Base system — kernel core (kern) · sys/kern/subr_alist.c:286 · pass 2 · new

 panic reproduced fixed
DF-2973 Low 6.0 eventhandler_deregister() performs no tag/list validation — wrong-list or stale tag deterministically corrupts both lists' tail sentinels (write-after-free, cross-list handler aliasing, double free); tag==NULL silently frees an entire shared list
