KVM: x86: Nullify irqfd->producer if updating IRTE for bypass fails
Nullify irqfd->producer if updating the IRTE for bypass fails, as leaving a
dangling pointer will result in a use-after-free if the irqfd is reachable
through KVM's routing, but the producer is freed separately. E.g. for VFIO
PCI, the producer is embedded in struct "vfio_pci_irq_ctx" and freed when
the vector is disabled, which can happen independent of routing updates.

| In the Linux kernel, the following vulnerability has been resolved:
ASoC: SOF: ipc4-control: Fix TOCTOU in sof_ipc4_bytes_put
In sof_ipc4_bytes_put(), the copy size is derived from the old
data->size in the buffer rather than the incoming new data's size
field from ucontrol. If the new data has a different size, the copy
uses the wrong length: it may truncate valid data or copy stale bytes.
Fix by validating and using the incoming data's sof_abi_hdr.size from
ucontrol before copying. |

| The Post Grid, Slider & Carousel Ultimate WordPress plugin before 1.8.1 does not sanitise and escape one of its custom post type settings before outputting it in an HTML attribute on the admin edit screen, allowing users with the Contributor role and above to inject JavaScript that executes in the session of any administrator who opens the affected item. |
| The FiboSearch WordPress plugin before 1.34.1 does not consistently exclude password-protected products from its unauthenticated AJAX endpoints, allowing unauthenticated users to disclose and enumerate password-protected products and their metadata without entering the product password. Two endpoints are affected: the autocomplete search endpoint (dgwt_wcas_ajax_search) and the Details Panel endpoint (dgwt_wcas_result_details) when queried for taxonomy details. |
| The ManageWP Worker WordPress plugin before 4.9.37 does not bind the account being logged in to the signature which authorises the login, nor prevent an already used login link from being replayed, allowing attackers who obtain such a link to gain a session as any user on the site, including an administrator. |
| The Tutor LMS WordPress plugin before 4.0.6 does not validate a stored file path before using it to stream media, allowing users with the instructor role to read arbitrary files on the server, including files outside the web root.
The readable files include the WordPress configuration file, which exposes the database credentials and the authentication keys and salts, so authentication cookies can be forged. |
| The Forminator Forms WordPress plugin before 1.57.0.5 does not restrict a network-wide setting to network administrators, allowing an administrator of any single site on a multisite network to execute arbitrary code across the entire network. |
| The Forminator Forms WordPress plugin before 1.57.0.7 does not consistently enforce the role restriction it applies to registration forms, allowing users who are permitted to build forms to configure one that assigns the administrator role to any visitor who registers through it. |

KVM: arm64: vgic: Handle race between interrupt affinity change and LPI disabling
Hyunwoo Kim reports some really bad races should the following
situation occur:
- LPI-I is pending in vcpu-B's AP list
- vcpu-A writes to vcpu-B's RD to disable its LPIs
- vcpu-C moves I from B to C
If the last two race nicely enough, vgic_prune_ap_list() can drop
the irq and AP list locks, reacquire them, and in the interval
the irq has been freed. UAF follows.
The fix is two-fold:
- Before dropping the irq and ap_list locks, take a reference on
the irq
- Do not try to handle migration of the pending bit: there is no
expectation that this state is retained, as per the architecture
With that, we're sure that the interrupt is still around, and we
safely remove it from the AP list as it has no target at this
stage (unless another interrupt fires, but that's another story). |
| In the Linux kernel, the following vulnerability has been resolved:
KVM: arm64: vgic: Check the interrupt is still ours before migrating it
vgic_prune_ap_list() drops both ap_list_lock and irq_lock while migrating
an interrupt to another vCPU. After reacquiring the locks it only checks
that the affinity is unchanged (target_vcpu == vgic_target_oracle(irq))
before moving the interrupt, which assumes that an interrupt whose affinity
is preserved is still queued on this vCPU's ap_list.
That assumption no longer holds if the interrupt is taken off the ap_list
while the locks are dropped. vgic_flush_pending_lpis() removes the
interrupt from the list and sets irq->vcpu to NULL, but leaves
enabled/pending/target_vcpu untouched. As the interrupt is still enabled
and pending, vgic_target_oracle() returns the same target_vcpu, so the
affinity check passes and list_del() is run a second time on an entry that
has already been removed.
Also check that the interrupt is still assigned to this vCPU
(irq->vcpu == vcpu) before moving it. |

| In the Linux kernel, the following vulnerability has been resolved:
drm/xe: free madvise VMA array on L2 flush failure
xe_vm_madvise_ioctl() allocates madvise_range.vmas in get_vmas().
After get_vmas() succeeds with at least one VMA, error paths must go
through free_vmas so the array is released before the madvise details are
destroyed.
The L2 flush validation path added for PAT madvise rejects some
SVM/userptr ranges after get_vmas() has succeeded, but jumps directly to
madv_fini. This skips kfree(madvise_range.vmas), leaking the VMA array on
each failed ioctl.
Jump to free_vmas instead, matching the other validation failure paths
after get_vmas() has succeeded.

octeontx2-af: fix VF bringup affecting PF promiscuous state
Mbox handling of nix_set_rx_mode for a VF with promiscuous and
all_multi flags set to false causes deletion of the PF's promiscuous
and allmulti MCAM rules. This occurs because the APIs that
enable/disable these rules operate only on the PF, even when the
mbox request is made via a VF interface.
Guard both rvu_npc_enable_allmulti_entry() and
rvu_npc_enable_promisc_entry() disable paths with an is_vf() check so
that a VF bringing up or tearing down its interface cannot inadvertently
clear the PF's MCAM rules. |

drm/fb-helper: Only consider active CRTCs for vblank sync
Only synchronize fbdev output to the vblank of an active CRTC. Go over
the list of CRTCs and pick the first that matches. Fixes warnings as
the one shown below
[ 77.201354] WARNING: drivers/gpu/drm/drm_vblank.c:1320 at drm_crtc_wait_one_vblank+0x194/0x1cc [drm], CPU#1: kworker/1:7/1867
[ 77.201354] omapdrm omapdrm.0: [drm] vblank wait timed out on crtc 0
This currently happens if the fbdev output is not on CRTC 0.
Atomic and non-atomic drivers require distinct code paths. As for other
fbdev operations, implement both and select the correct one at runtime.
Not finding an active CRTC is not a bug. Do not wait in this case, but
flush the display update as before.
v4:
- avoid possible deadlocks with locking context (Sashiko)
v3:
- drop excessive state validation (Jani)
- acquire plane and CRTC mutices (Sashiko)
v2:
- move look-up code into separate helper
- support drivers with legacy modesetting

smb: client: fix busy dentry warning on unmount after DIO
Commit c68337442f03 ("cifs: Fix busy dentry used after unmounting") fixed
the issue in cifs where deferred close of a file led to a dentry reference
count not being released in umount, by flushing deferredclose_wq in
cifs_kill_sb() to solve it.
However, the cifs DIO path suffers from the same busy-dentry problem caused
by a delayed dentry reference-count release:

...
cifs_demultiplex_thread

--cfile->count
queue_work(fileinfo_put_wq, xxx)
[fileinfo_put_wq] [6]
cifsFileInfo_put_work
cifsFileInfo_put_final
dput
If the umount path is triggered before [5], it results warning:
BUG: Dentry 00000000eab1f070{i=9a917b66ae404fec,n=test} still in use (1)
[unmount of cifs cifs]
The existing per-inode ictx->io_count wait in cifs_evict_inode() does not
help: it lives in the inode eviction path, which runs after
shrink_dcache_for_umount() has already warned about the busy dentries.
Fix it by adding a per-superblock outstanding-rreq counter that is
incremented in cifs_init_request() and decremented in cifs_free_request().
In cifs_kill_sb(), before kill_anon_super(), wait for this counter to reach
0 - which guarantees that all cleanup_work for this sb have run and thus
all relevant cfile puts are queued on fileinfo_put_wq or serverclose_wq.
Then drain the workqueue so the dentry refs are dropped.
This is a targeted wait, not a flush of the system-wide system_dfl_wq. |

SUNRPC: pin upper rpc_clnt across the TLS connect_worker
The TLS connect path has a use-after-free: nothing pins the
upper rpc_clnt across the delayed connect_worker. xs_connect()
stores task->tk_client in sock_xprt::clnt as a raw pointer
and queues the worker; for TLS-secured transports that worker
is xs_tcp_tls_setup_socket(), which reads several fields out
of the saved pointer (cl_timeout, cl_program, cl_prog,
cl_vers, cl_cred, cl_stats) to construct the args for the
inner handshake rpc_clnt.
The xprt does not reference the rpc_clnt; the rpc_clnt
references the xprt. xs_destroy() does cancel the
connect_worker, but it runs only when the xprt's refcount
drops to zero, which cannot happen until the rpc_clnt
releases its cl_xprt reference in rpc_free_client_work().
When a TLS handshake fails fatally (for example, an mTLS
mount whose client cert does not match the server), the
connecting task is woken with -EACCES and exits, the mount
caller invokes rpc_shutdown_client(), and the upper rpc_clnt
is freed before the queued connect_worker fires.
xs_tcp_tls_setup_socket() then dereferences the freed clnt,
producing the refcount_t underflow Michael Nemanov reported.
Take a reference on the upper rpc_clnt in xs_connect() for
TLS transports via a new rpc_hold_client() helper, and drop
it in the connect_worker's exit path with rpc_release_client().
The xprt_lock_connect() / xprt_unlock_connect() pairing
already serialises xs_connect() with xs_tcp_tls_setup_socket(),
so the take and release are balanced one-for-one.
The non-TLS connect worker (xs_tcp_setup_socket) never reads
sock_xprt::clnt, so leave that path alone and avoid the
clnt-holds-xprt-holds-clnt cycle that would otherwise prevent
xprt destruction. |
