CVSS v3.1 |
| XenForo before 2.3.13 contains a missing authorization vulnerability in the ACP cache-rebuild dispatcher that allows limited administrators with only the rebuildCache permission to perform unauthorized approval queue actions by supplying an arbitrary job class and actor user ID in the POST body. Attackers can invoke the approval queue job under any user identity to approve queued user registrations without holding the required approval-queue or moderator permissions, causing the moderation log to attribute actions to an impersonated account. |
| In the Linux kernel, the following vulnerability has been resolved:
usb: typec: thunderbolt: Disable work before freeing tbt on remove
tbt_altmode_remove() drops the plug and cable references without
draining tbt->work. The work function dereferences those references,
and can also requeue itself in its error path. The VDM callbacks can
queue the same work item.
Disable and drain tbt->work before dropping the references. This waits
for an existing invocation and prevents subsequent schedule_work()
calls from queueing it during teardown.
This issue was found by an in-house static analysis tool and confirmed
by manual code review. |
| In the Linux kernel, the following vulnerability has been resolved:
NFSD: Prevent post-shutdown use-after-free in unlock_filesystem
Writing a filesystem path to /proc/fs/nfsd/unlock_filesystem runs
nfsd4_cancel_copy_by_sb() before nfsd_mutex is held and before the
handler confirms that nn->nfsd_serv is set. Once nfsd has shut down,
nfs4_state_destroy_net() has freed nn->conf_id_hashtbl but left the
pointer intact, so the cancel helper iterates freed slab memory as an
array of struct list_head and then dereferences a bogus nfs4_client
when it takes clp->async_lock. A local administrator holding
CAP_SYS_ADMIN can reach this use-after-free by stopping the server and
then writing to unlock_filesystem; KASAN reports a slab-use-after-free
read in nfsd4_cancel_copy_by_sb().
nfsd4_revoke_states() walks the same state tables and for that reason
already runs only under nfsd_mutex with nn->nfsd_serv confirmed
present. Move the async COPY cancel into that protected section so
every NFSv4 state-table walker on this path observes a running server.
Async copies exist only while the server runs, so gating the cancel on
nn->nfsd_serv loses nothing. |
| In the Linux kernel, the following vulnerability has been resolved:
dm-io: clone the source bio instead of copying its biovec
For DM_IO_BIO requests, do_region() built each destination bio by walking
the source bio's biovec and re-adding the pages one at a time, tracking
the remaining transfer in sectors. The vector lengths are byte granular
and need not be sector aligned (e.g. a misaligned O_DIRECT buffer split
across pages), so the sector-based accounting could lose a sub-sector
fragment: to_sector() truncated the remainder and the outer loop spun
forever submitting empty bios, hanging the I/O.
There is no need to rebuild the biovec at all. The destination reads into
(or writes from) exactly the same pages as the source bio, so the bio can
simply clone the source's biovec with bio_alloc_clone() and remap it to
the target device. The clone inherits the source's iterator and alignment,
and the block layer splits it to the target's limits on submission, so the
whole region maps to a single cloned bio with no manual page copying or
sector accounting.
This removes the per-page copy path (and its open-coded bvec dpages
helpers) for bio-backed I/O and fixes the hang on misaligned direct I/O to
a dm-mirror device. Page-list, vma and kmem sources keep the existing copy
path. |
| In the Linux kernel, the following vulnerability has been resolved:
sched_ext: Fix this_rq() assumptions in dispatch kfuncs
Under core scheduling, dispatch runs from within the core-wide pick and can
target a sibling rq, so ops.dispatch() may execute on a CPU different from
the dispatched rq's. Several kfunc paths assumed the two always coincide:
- scx_dsq_move() decided whether an rq lock is held by testing this_rq()'s
rq flags and lock-danced accordingly. A dispatch for a sibling took the
unlocked-context branch and acquired the source rq lock on top of the
already held dispatched rq lock which could deadlock.
- scx_bpf_sub_dispatch() dispatched this_rq() with its stashed
sub_dispatch_prev, which is NULL when dispatching for a sibling.
- finish_dispatch(), scx_bpf_dsq_reenq() and scx_bpf_dsq_nr_queued()
resolved SCX_DSQ_LOCAL to this CPU's local DSQ rather than the dispatched
rq's. The latter two are callable from other rq-locked operations too,
where SCX_DSQ_LOCAL now likewise resolves to the op's rq. This changes
behavior also without core scheduling, e.g. for ops.enqueue() running a
remote wakeup on the waking CPU, and is intended: which CPU happens to
execute an operation is incidental, the op's rq is what it is operating
on, and the resolution now matches the insert side where SCX_DSQ_LOCAL
dispatches land on the task's rq.
Use the rq tracked by scx_locked_rq(), which is set to the dispatched rq
around ops invocations and NULL in unlocked contexts. |
| In the Linux kernel, the following vulnerability has been resolved:
sched_ext: Don't BUG_ON a destroyed DSQ in process_deferred_reenq_users
scx_bpf_dsq_reenq() queues a deferred reenq (dru) that runs from
run_deferred(), not ops.dispatch(). If the DSQ is destroyed before the dru
runs, process_deferred_reenq_users() sees dsq->id == SCX_DSQ_INVALID and
hits the BUG_ON. destroy_dsq() doesn't flush pending drus, so just skip.
tj: Read dsq->id once with READ_ONCE(). Reading it separately in the INVALID
check and the BUG_ON would leave a window where destroy_dsq() can
invalidate the id between the two reads and still trigger the BUG_ON. |
| In the Linux kernel, the following vulnerability has been resolved:
RDMA/uverbs: Guard legacy bundles without method_elm
The legacy write() path dispatches through a uverbs_api_write_method, but
the uverbs_attr_bundle passed to provider code does not have an ioctl
method element. If malformed provider input causes the common uverbs
validation code to emit an error message, uverbs_get_handler_fn()
dereferences the uninitialized method_elm pointer.
Initialize method_elm explicitly for legacy bundles and make
uverbs_get_handler_fn() return NULL when no ioctl method is present. The
legacy dispatcher continues to use its local write method, while the ioctl
path continues to use the registered ioctl handler. |
| In the Linux kernel, the following vulnerability has been resolved:
PCI: plda: Fix use-after-free of event IRQs during teardown
plda_pcie_irq_domain_deinit() removes pcie->event_domain via
irq_domain_remove(), but the per-event IRQs mapped from that domain
are requested with devm_request_irq() in plda_init_interrupts(). The
actual free_irq() for a devm-managed IRQ is deferred by devres until
after the calling probe()/remove() function returns.
This means irq_domain_remove() can free the domain's internal data
before the deferred free_irq() for IRQs still mapped into it has run.
When devres later processes that deferred cleanup, it can end up
dereferencing the already-freed domain.
Free each event IRQ explicitly with devm_free_irq() before removing
the domain. This triggers the free immediately and removes the IRQ
from the devres tracking list, so devres will not attempt to free it
a second time later.
Also dispose of the event, INTx, and MSI IRQ mappings with
irq_dispose_mapping() before their owning domains are removed.
Finally, guard the calls to irq_set_chained_handler_and_data() for
pcie->irq, pcie->msi_irq, and pcie->intx_irq so they only run when
those fields hold a valid (>0) IRQ number.
This is a pre-existing issue, flagged by automated review during work
on an earlier, unrelated patch to this driver.

| Forgejo before 16.0.4 allows use of restricted API tokens for unintended access to the "allow maintainer edit" feature. |
| In the Linux kernel, the following vulnerability has been resolved:
dm-pcache: detect a cycle in the last-kset chain during replay
cache_replay() follows the on-media last-kset chain by next_cache_seg_id
with no cond_resched(). A forged chain that points back into a segment it
has already visited makes the replay loop follow it forever.
Cap the last-kset hops at cache->n_segs; a valid chain visits each segment
at most once. |
| In the Linux kernel, the following vulnerability has been resolved:
dm-pcache: only hand out initialized cache segments
get_cache_segment() scans the segment map up to cache->n_segs, the
physical device segment count, but cache_segs_init() only initializes
the first cache_info->n_segs segments. A crafted image with
cache_info->n_segs smaller than the device count leaves the remaining
pcache_cache_segment structs zeroed (segment.data == NULL), and the
allocator can hand one to cache_kset_close(), which writes through the
returned segment's data pointer with no NULL check.
Bound the allocator's search to cache_info->n_segs so only initialized
segments are ever returned. A conforming cache sets n_segs equal to the
device segment count, so this rejects nothing legitimate. |
