ksmbd: fix use-after-free of fp->owner.name in durable handle owner check
Two concurrent SMB2 durable reconnects (DH2C/DHnC) on the same
persistent_id race the fp->owner.name compare-read in
ksmbd_vfs_compare_durable_owner() against the kfree() in
ksmbd_reopen_durable_fd()'s reopen-success path. fp->owner.name is a
standalone kstrdup() buffer whose lifetime is independent of the fp
refcount, and the two sites share no lock: the compare reads the buffer
while the reopen frees it, so the strcmp() can dereference freed memory.
Commit 7ce4fc40018d ("ksmbd: fix durable reconnect double-bind race in
ksmbd_reopen_durable_fd") made the fp->conn claim atomic under
global_ft.lock (closing the owner.name double-free and the ksmbd_file
write-UAF), but the compare-read versus reopen-free pair was left
unserialized.

Serialize both sides of the race with fp->f_lock. The global durable
file-table lock still protects the durable reconnect claim, but
fp->owner.name is per-open state and does not need to block unrelated
durable table lookups or reconnects. The teardown is left at its
existing location after the reopen-success point so that an __open_id()
rollback still retains owner.name for a later legitimate reconnect to
verify. |

hwmon: (pmbus) Fix passing events to regulator core
Sashiko reports:
Commit 754bd2b4a084 ("hwmon: (pmbus/core) Protect regulator operations with
mutex") introduced a worker to batch regulator events over time using
atomic_or(). The delayed worker then passes the combined bitmask unmodified
to regulator_notifier_call_chain().
The core regulator subsystem's regulator_handle_critical() function
evaluates the event parameter using a strict switch statement. If
multiple distinct faults occur before the worker runs (e.g.,
REGULATOR_EVENT_UNDER_VOLTAGE | REGULATOR_EVENT_OVER_CURRENT), the combined
bitmask fails to match any case. This leaves the reason as NULL and
completely bypasses the critical hw_protection_trigger().
Fix the problem by passing events bit by bit to the regulator event
handler. |
| In the Linux kernel, the following vulnerability has been resolved:
hwmon: (pmbus/core) honor vrm_version in pmbus_data2reg_vid()
pmbus_data2reg_vid() hardcoded the VR11 encoding regardless of the
vrm_version configured by the driver, while pmbus_reg2data_vid()
already switched on it. Any driver that selects a non-VR11 VID mode
and exposes a regulator (or hwmon vout setter) sent dangerously
wrong codes to PMBUS_VOUT_COMMAND -- e.g. an nvidia195mv part asked
for 200 mV got the VR11 clamp to 500 mV encoded as 0xB2, which the
chip interprets as 1080 mV.
Mirror pmbus_reg2data_vid() so writes round-trip with reads. |
| In the Linux kernel, the following vulnerability has been resolved:
geneve: gate GRO hint in geneve_gro_complete() on gs->gro_hint
geneve_gro_receive() reads the GRO hint through geneve_sk_gro_hint_off(),
which honours it only when the socket enabled IFLA_GENEVE_GRO_HINT
(gs->gro_hint). geneve_gro_complete() instead calls the low-level
geneve_opt_gro_hint_off() and acts on the hint unconditionally.
On a tunnel without the hint, receive aggregates the frames as plain
ETH_P_TEB while complete still honours an attacker-supplied hint option: it
inflates gh_len by gro_hint->nested_hdr_len (u8) and redirects the dispatch
type, so the inner gro_complete handler runs at nhoff + gh_len, an offset
receive never pulled nor validated, reading out of bounds of the skb head:

ASoC: SDCA: Validate written enum value in ge_put_enum_double()
ge_put_enum_double() passes the user-supplied enumeration index
item[0] to snd_soc_enum_item_to_val() without checking it against the
number of items in the enum:
ret = snd_soc_enum_item_to_val(e, item[0]);
snd_soc_enum_item_to_val() indexes the heap-allocated e->values[] array
with that index (e->values is set from a devm_kcalloc() of e->items
entries), so a control write with an out-of-range item[0] reads past the
end of the values buffer. The bounds check in
snd_soc_dapm_put_enum_double() only runs afterwards, so it does not
prevent the read here.
Reject an out-of-range item before using it, matching the other enum put
handlers.
This issue was pointed out by the Sashiko AI review bot while reviewing a
related enum-validation series:

| In the Linux kernel, the following vulnerability has been resolved:
netfilter: nf_conncount: prevent connlimit drops for early confirmed ct
Commit 69894e5b4c5e ("netfilter: nft_connlimit: update the count if add
was skipped") introduced a regression where packets for valid
connections are dropped when using connlimit for soft-limiting
scenarios.
The issue occurs when a new connection reuses a socket currently in
the TIME_WAIT state. In this scenario, the connection tracking entry
is evaluated as already confirmed. Previously, __nf_conncount_add()
assumed that if a connection was confirmed and did not originate from
the loopback interface, it should skip the addition and return -EEXIST.
Skipping the addition triggers a garbage collection run that cleans up
the TIME_WAIT connection. Consequently, the active connection count
drops to 0, which xt_connlimit mishandles, leading to the false rejection
of the perfectly valid new connection.
Fix this by replacing the interface check with protocol-agnostic state
checks. We now skip the tree insertion and preserve the lockless garbage
collection optimization only if the connection is IPS_ASSURED. This
allows early-confirmed setup packets (such as reused TIME_WAIT sockets
or locally generated SYN-ACKs) to be properly evaluated and counted
without falsely dropping. The goto check_connections path is maintained
to ensure these setup packets are deduplicated correctly.
This has been tested with slowhttptest and HTTP server configured
locally to ensure we are not breaking soft-limiting scenarios for local
or external connections. In addition, it was tested with a OVS zone
limit too. |
| In the Linux kernel, the following vulnerability has been resolved:
md/raid10: fix writes_pending and barrier reference leaks on discard failures
raid10_make_request() acquires a writes_pending reference with
md_write_start() before calling raid10_handle_discard(). Several failure
paths in raid10_handle_discard() complete the bio and return without
releasing the corresponding reference, causing md_write_end() to be
skipped.
Call md_write_end() before returning from these failure paths to keep
writes_pending accounting balanced.
Additionally, discard split allocation failures can occur after
wait_barrier() succeeds. Those paths return without calling
allow_barrier(), leaking the associated barrier reference.
Release the barrier before returning from those paths. |

| Improper Handling of Case Sensitivity vulnerability in elixir-tesla tesla allows credential leakage to a third-party origin on cross-origin redirects.
Tesla.Middleware.FollowRedirects strips security-sensitive headers on cross-origin redirects using a case-sensitive string comparison against a lowercase filter list (@filter_headers ["authorization", "host"]). HTTP header names are case-insensitive per RFC 7230, but Tesla preserves header keys verbatim as supplied by the caller without normalizing case. A header set as {"Authorization", "Bearer …"} (the RFC 7235 canonical casing used by virtually all HTTP libraries and documentation) does not match the lowercase filter entry and is forwarded to the redirect destination. An attacker who can control or influence a Location: response seen by the client (via their own endpoint, a redirect-open upstream, or a compromised origin) receives the bearer token or other Authorization material on the cross-origin request.
This issue affects tesla: from 1.4.0 before 1.18.3. |

| In the Linux kernel, the following vulnerability has been resolved:
can: bcm: fix stale rx/tx ops after device removal
RX: an RX_SETUP update(!) for an existing op skipped can_rx_register()
unconditionally, even when a concurrent NETDEV_UNREGISTER had already
torn down its registration (op->rx_reg_dev == NULL). This silently
did not re-enable frame delivery for that updated filter. bcm_rx_setup()
now re-registers in that case, while leaving rx_ops with ifindex = 0
(all CAN devices) which never carry a tracked rx_reg_dev registered as-is.
TX: bcm_notify() only handled bo->rx_ops on NETDEV_UNREGISTER, leaving
tx_ops with an active cyclic transmission re-arming its hrtimer
indefinitely to execute bcm_tx_timeout_handler(). Cancelling the hrtimer
prevents the runaway timer and any injection into a later reused ifindex,
since nothing else calls bcm_can_tx() for the op until an explicit
TX_SETUP update re-arms it.
Unlike bcm_rx_unreg(), which clears the tracked rx_reg_dev for rx_ops,
the ifindex is intentionally left unchanged for tx_ops. bcm_tx_setup()
always rejects ifindex 0, so clearing it would strand the op: neither a
later TX_SETUP (bcm_find_op()) nor TX_DELETE (bcm_delete_tx_op()) could
ever find it again, since both require an exact ifindex match. |
| In the Linux kernel, the following vulnerability has been resolved:
xfrm: xfrm_interface: require CAP_NET_ADMIN in the device netns for changelink
xfrmi_changelink() operates on at most two netns, dev_net(dev) and the
interface link netns xi->net. They differ once the device is created in
or moved to a netns other than the one the request runs in. The rtnl
changelink path checks CAP_NET_ADMIN only against dev_net(dev), so a
caller privileged there but not in xi->net can rewrite an interface that
lives in xi->net.
Gate xfrmi_changelink() on rtnl_dev_link_net_capable() at its top,
before any attribute is parsed. |
| In the Linux kernel, the following vulnerability has been resolved:
landlock: Fix LANDLOCK_SCOPE_SIGNAL bypass on the SIGIO path
LANDLOCK_SCOPE_SIGNAL must prevent a sandboxed process from signaling
processes outside its Landlock domain. It can be bypassed through the
asynchronous SIGIO delivery path.
A sandboxed process that owns any file or socket can arm it with
fcntl(fd, F_SETOWN, -pgid), fcntl(fd, F_SETSIG, SIGKILL) and O_ASYNC, so
that an I/O event makes the kernel deliver the chosen signal to the
whole process group. As the head of its process group's task list (the
default position right after fork()) that group can also hold the
non-sandboxed process that launched it, e.g. a supervisor or a security
monitor. The sandbox can thus kill or signal the processes
LANDLOCK_SCOPE_SIGNAL is meant to protect from it.
The scope is enforced in hook_file_send_sigiotask() against the Landlock
domain recorded at F_SETOWN time, not the live domain of the sender.
control_current_fowner() decides whether to record that domain and skips
recording it when the fowner target is in the caller's thread group,
which is safe only for a single-task target (PIDTYPE_PID, PIDTYPE_TGID).
For a process group (PIDTYPE_PGID) pid_task() returns only one member;
recording is skipped whenever that member shares the caller's thread
group, and hook_file_send_sigiotask() then lets the signal fan out to
the whole group unchecked.
Record the domain for every non single-process target so the scope is
enforced against each group member at delivery time.
That recording is necessary but not sufficient on its own: the kernel
signals a process group through its members' thread-group leaders, and
the leader of the registrant's own process can carry a different
Landlock domain than the sibling thread that armed the owner.
domain_is_scoped() would then deny that leader, even though commit
18eb75f3af40 ("landlock: Always allow signals between threads of the
same process") requires same-process delivery to be allowed.
hook_task_kill() avoids this by evaluating same_thread_group() live, per
recipient; the SIGIO path instead delegates the whole decision to a
single registration-time check, which a process-group fan-out cannot
honor.
So also record the registrant's thread group next to its domain and
exempt it at delivery: hook_file_send_sigiotask() allows the signal
whenever the recipient belongs to the registrant's own process,
restoring the same-process guarantee while keeping out-of-domain group
members blocked. The direct kill() path (hook_task_kill) already
evaluates the live domain and is unaffected.

ntfs: fix WARN_ON for resident attribute in ntfs_map_runlist_nolock()
When ntfs_map_runlist_nolock() needs to look up the attribute extent
containing a target VCN (ctx_needs_reset == true), it calls
ntfs_attr_lookup() and then expects the result to be a non-resident
attribute, since only non-resident attributes have a mapping pairs
array to decompress.
A crafted NTFS image can place a resident attribute where a non-resident
one is expected, causing ntfs_attr_lookup() to succeed but return a
resident attribute record. Previously this was caught only by a
WARN_ON(), which does not stop execution. The code then falls through to
read a->data.non_resident.highest_vcn from what is actually a resident
attribute, accessing the wrong union member and corrupting the VCN range
check.
The caller path triggering this warning during mount is:
ntfs_map_runlist_nolock
ntfs_empty_logfile
load_system_files
ntfs_fill_super
In this path ctx is NULL, so ntfs_map_runlist_nolock() allocates a
temporary search context internally and sets ctx_needs_reset = true.
The existing resident-attribute guard in the ctx != NULL branch already
returns -EIO silently for the same condition; make the ctx_needs_reset
path consistent by replacing the WARN_ON() with the same -EIO error
return.
This causes the crafted image to be rejected with a mount error instead
of triggering a kernel warning. |
| In the Linux kernel, the following vulnerability has been resolved:
ntfs: make system files immutable to prevent corruption
When a system file such as $Bitmap is exposed via show_sys_files and
written from userspace, the volume is corrupted and, because the cluster
allocator scans $Bitmap through the same inode's page cache, a write to
$Bitmap also deadlocks writeback against the folio it already holds locked.
These files are maintained by the driver itself and have no valid reason
to be written through the file interface. Mark base metadata files
(mft_no < FILE_first_user) as immutable during inode read so the VFS
rejects write, mmap, truncate and unlink with -EPERM. Directories are
skipped so the root and $Extend remain usable. Internal metadata updates
do not go through the VFS write path and are unaffected. |
| In the Linux kernel, the following vulnerability has been resolved:
ntfs: sanitize MFT references returned from ntfs_lookup_inode_by_name()
ntfs_lookup_inode_by_name() returns MFT references read from directory
index entries on disk. These values are untrusted, but the function can
currently return an error-marked MFT reference to its callers without
validating it.
Callers later decode lookup failures with MREF_ERR(). A crafted NTFS image
can set the MREF error bit while leaving the low bits as an arbitrary
value, causing callers to consume a bogus pseudo-errno instead of treating
the lookup result as corrupted on-disk metadata.
Fix this at the source by normalizing every error-marked MFT reference
returned from ntfs_lookup_inode_by_name() to ERR_MREF(-EIO). Apply this to
all four directory lookup return paths so every caller gets a validated
result without needing additional checks or an API change.
This keeps the sanitization in the common lookup helper, which is cleaner
than duplicating validation in each caller. |
