| In the Linux kernel, the following vulnerability has been resolved:
PCI: mediatek: Protect root bus removal with rescan lock
Hold the pci_rescan_remove_lock lock while stopping and removing a root bus
to avoid racing with concurrent rescan or hotplug operations triggered via
sysfs. Such races may lead to use-after-free issues or system crashes.

| In the Linux kernel, the following vulnerability has been resolved:
perf: Fix addr_filter_ranges lifetime
Lee Jia Jie reported that since event::addr_filter_ranges is used
under RCU, it should be RCU freed. |
| In the Linux kernel, the following vulnerability has been resolved:
f2fs: validate inline dentry name lengths before conversion
Inline dentry conversion copies names out of the inline dentry area
before checking that each recorded name length fits in the available
filename slots.
A corrupted image can therefore make the conversion path read past
the inline filename storage while building the regular dentry block.
Validate each inline dentry name length against the inline filename
area before copying it. |
| In the Linux kernel, the following vulnerability has been resolved:
net: au1000: move free_irq out of the close-time spinlocked section
au1000_close() calls free_irq() while aup->lock is still held with
spin_lock_irqsave(). free_irq() can sleep because it takes the IRQ
descriptor request mutex, so it does not belong inside the close-time
spinlocked section.
This was found by our static analysis tool and then confirmed by manual
review of the in-tree au1000_close() .ndo_stop path. The reviewed path
keeps aup->lock held across the MAC reset, queue stop and
free_irq(dev->irq, dev).
A directed runtime validation kept that ndo_stop carrier and the same
free_irq(dev->irq, dev) operation under the driver lock. Lockdep reported
"BUG: sleeping function called from invalid context" and "Invalid wait
context" while free_irq() was taking desc->request_mutex, with
au1000_close() and free_irq() on the stack.
Drop aup->lock before freeing the IRQ. The protected close-time work still
stops the device and queue before IRQ teardown, but the sleepable IRQ core
path now runs outside the spinlocked section. |
| In the Linux kernel, the following vulnerability has been resolved:
spi: core: Abort active target transfer on controller suspend
When an SPI controller operating in target mode has a transfer in
progress at the time of system suspend, the suspend path proceeds
without aborting the ongoing transfer. This can leave the hardware in
an inconsistent state, potentially causing the system to hang or fail
to resume cleanly.
Fix this by invoking the controller's target_abort callback from
spi_controller_suspend() when the controller is in target mode and the
callback is registered. This ensures any active target transfer is
cleanly terminated before the controller is suspended. |
| In the Linux kernel, the following vulnerability has been resolved:

The itemsize matches the namelen, but the namelen is 4096, way larger
than normal name length limit (BTRFS_NAME_LEN, 255).
Meanwhile the memory of the @name is only 255 byte sized, this will cause
out-of-boundary access, and cause the above crash.
[FIX]
Add extra namelen verification for INODE_REF, just like what we have
done in ROOT_REF checks.
Now the crafted image can be rejected gracefully:
BTRFS critical (device dm-2): corrupt leaf: root=5 block=30572544 slot=14 ino=259, invalid inode ref name length, has 4096 expect [1, 255]

| In the Linux kernel, the following vulnerability has been resolved:
ksmbd: fix sd_ndr.data memory leak in ksmbd_vfs_set_sd_xattr
ndr_encode_v4_ntacl() allocates sd_ndr.data via kzalloc() at entry.
If any subsequent ndr_write_*() call returns error during encoding,
the allocated sd_ndr.data won't be freed and causes memory leak.
Move kfree(sd_ndr.data) into out label to ensure the buffer gets
released on all success and error return paths. |
| Termix is a web-based server management platform with SSH terminal, tunneling, and file editing capabilities. From 2.5.0 until 2.5.1, the /homepage/proxy endpoint accepts an authenticated user's url query parameter and passes it to http.get or https.get without destination restrictions. In src/backend/database/routes/homepage-proxy-routes.ts, new URL performs only syntactic validation, allowing requests to loopback, RFC1918, link-local, and cloud metadata destinations. The endpoint returns the complete fetched JSON response, so a low-privilege or self-registered account can exfiltrate internal service data and cloud credentials. This issue is fixed in version 2.5.1. |
| In the Linux kernel, the following vulnerability has been resolved:
ksmbd: Fix acl.sd_buf memory leak and invalid sd_size error handling
1. When ndr_decode_v4_ntacl() fails, the code jumped to free_n_data
which only freed n.data, skipping kfree(acl.sd_buf) and leaking
the buffer. Zero-initialize struct xattr_ntacl acl, reorder error
labels to out_free to release acl.sd_buf on all error paths.
2. if (acl.sd_size < sizeof(struct smb_ntsd)) is true, original code
returned success without freeing sd_buf and left stale *pntsd.
Set rc = -EINVAL before jumping to out_free to return error code and
free buffer. |

| In the Linux kernel, the following vulnerability has been resolved:
ALSA: usb-audio: caiaq: validate EP1 reply lengths
usb_ep1_command_reply_dispatch() uses buf[0] as a command byte and then
reads command-specific fixed items from the same URB buffer. Several
paths use buf + 1, buf[1], buf[2], or buf + 3 without first proving that
urb->actual_length contains those bytes.
Add per-command length checks, use a payload length derived from the
bytes after the command byte for the control-state copy, and reject short
analog input payloads before the input helper reads fixed offsets from
the EP1 reply. |
| In the Linux kernel, the following vulnerability has been resolved:
wifi: rsi: avoid reading TKIP MIC keys for non-TKIP ciphers
rsi_hal_load_key() copies tx_mic_key and rx_mic_key from data[16] and
data[24] whenever key data is present. Those offsets are only part of
the 32-byte TKIP key layout. Shorter keys used by other ciphers, such as
CCMP, do not provide those bytes, so the unconditional copies can read
past the supplied key buffer.
Only copy the MIC keys for TKIP, and reject malformed TKIP keys that are
shorter than the expected 32-byte layout.

| In the Linux kernel, the following vulnerability has been resolved:
wifi: cfg80211: validate assoc response length before status and IE access
cfg80211_rx_assoc_resp() initialises the status and response-IE fields
of cfg80211_connect_resp_params from the management frame before
proving that the frame is long enough for those offsets. S1G and
regular association responses also have different IE offsets, but the
S1G path only patched resp_ie after the unsafe initialiser had already
run.
Defer resp_ie, resp_ie_len, and status to after the link-iteration
loop. Use a bool to remember whether the frame is S1G, then validate
the appropriate minimum length and set all three fields in a single
if/else block. Funnel short-frame and SME-reject cleanup through a
shared free_bss label for the abandon paths. |
| In the Linux kernel, the following vulnerability has been resolved:
wifi: cfg80211: validate rx/tx MLME callback frame lengths before access
cfg80211_rx_mlme_mgmt() and cfg80211_tx_mlme_mgmt() call tracepoints
before rejecting frames shorter than the frame-control field. After
that, they only require len >= 2 before dispatching into subtype
handlers that assume their fixed fields are present.
The frames that trip this are not shorter than 2 bytes; they are short
relative to their subtype. mwifiex is a concrete in-tree example on the
length side: mwifiex_process_mgmt_packet() only requires a 4-address
ieee80211_hdr plus the 2-byte firmware length prefix before handing the
frame to cfg80211_rx_mlme_mgmt(). After stripping the length prefix and
removing addr4, pkt_len can be exactly 24: a bare 3-address management
header with no reason-code body. The existing WARN_ON(len < 2) does not
fire on such a frame, and cfg80211_process_deauth() then reads
u.deauth.reason_code as a two-byte access starting at offset 24,
immediately past the 24-byte buffer.
Add a frame-control length gate, then validate each subtype's minimum
frame size in an if/else-if chain that mirrors the dispatch logic. Trace
only after the frame is known to be well-formed.
Side effects of this change:
- The WARN_ON(len < 2) is dropped. It only guarded the frame_control
read, never the subtype fixed fields, and it does not fire on the
frames that actually trigger the out-of-bounds read (which are >= 2).
The len >= 2 check is kept as the guard before dereferencing
frame_control, but without the warning: these are exported callbacks
and a malformed frame from a driver should be dropped silently rather
than backtraced.
- cfg80211_tx_mlme_mgmt() previously routed every non-deauth subtype
through disassociation handling; it now silently ignores unrecognised
subtypes. |
| In the Linux kernel, the following vulnerability has been resolved:
wifi: mac80211: ibss: wait for in-flight TX on disconnect
While leaving an IBSS in ieee80211_ibss_disconnect() mac80211 flushes
stations, turns the carrier off and immediately tells the driver to
leave as well. While there may be synchronize_net() in station flush
and in this code later, packets can still be transmitted due to
cross-CPU race conditions after carrier off is set.
Therefore, it's possible for a race to happen where a TX to the
driver occurs while or after telling it to leave the IBSS. This can
be confusing to drivers, and in the case of iwlwifi leads to an
attempt to use invalid queues.
Move netif_carrier_off() to occur before sta_info_flush() during
IBSS disconnect, and add synchronize_net() if flushing didn't,
so that the synchronize_net() always happens between turning the
carrier off and telling the driver, avoiding this race. |
| In the Linux kernel, the following vulnerability has been resolved:
wifi: libipw: fix key index receive bound checks
libipw_rx() reads skb->data[hdrlen + 3] to extract the WEP key index in
both the software-decrypt key selection path and the hardware-decrypted
IV/ICV strip path. In both places the existing guard only checks
skb->len >= hdrlen + 3, which proves bytes up to hdrlen + 2 but not the
byte at hdrlen + 3.
Require hdrlen + 4 bytes before reading that item in both paths. This is
a local source-boundary check only; it does not change the key index
semantics. |
| In the Linux kernel, the following vulnerability has been resolved:
wifi: rsi: validate beacon length before fixed buffer copy
rsi_prepare_beacon() copies the mac80211 beacon frame after
FRAME_DESC_SZ into a management skb whose usable tailroom may be smaller
than MAX_MGMT_PKT_SIZE after alignment.
Validate the beacon length against the actual tailroom before the copy
and skb_put(). Leave ownership of the management skb with the caller on
error, matching the existing rsi_send_beacon() cleanup path. |
| In the Linux kernel, the following vulnerability has been resolved:
smb/client: zero-initialize stack-allocated cifs_open_info_data
Stack-allocated cifs_open_info_data may contain random data.
This can make some fields have wrong value if they are not set later. |
