CVSS v3.1 |
| Dell Display and Peripheral Manager (DDPM Windows), versions prior to 2.3.0.17, contain an Authentication Bypass by Spoofing vulnerability. A low privileged attacker with local access could potentially exploit this vulnerability, leading to Elevation of Privileges and arbitrary code execution. |
| In the Linux kernel, the following vulnerability has been resolved:
cpu: hotplug: Preserve per instance callback errors
cpuhp_invoke_callback() unwinds earlier callbacks for the same
hotplug state when one instance fails. The rollback path currently
reuses ret, so a successful rollback can hide the original error and
make the failed transition look successful.
Keep the rollback result separate from the original error. |
| In the Linux kernel, the following vulnerability has been resolved:
tracing/user_events: Fix use-after-free in user_event_mm_dup()
user_event_mm_dup() walks the parent mm's enabler list locklessly under
rcu_read_lock() during fork() (from copy_process()); it does not take
event_mutex:
rcu_read_lock();
list_for_each_entry_rcu(enabler, &old_mm->enablers, mm_enablers_link)
enabler->event = user_event_get(orig->event);
user_event_enabler_destroy() removes an enabler from that list with
list_del_rcu() and then, without waiting for a grace period, drops the
enabler's user_event reference with user_event_put() and frees the enabler
with kfree(). A reader that loaded the enabler before the list_del_rcu()
can still be walking it, which leads to two use-after-frees:
- kfree(enabler) frees the enabler while that reader dereferences
enabler->event.
- user_event_put() may drop the last reference to the user_event, which
is then freed (via delayed_destroy_user_event() on a work queue), while
the same reader does user_event_get(orig->event) on it.
Both are reachable by an unprivileged task that can open user_events_data:
one multithreaded process that registers an enabler and then concurrently
unregisters it and calls fork() triggers the race. KASAN reports a
slab-use-after-free in user_event_mm_dup() during clone(), with a
"refcount_t: addition on 0" warning when the user_event is freed.
The enabler use-after-free was found first; the user_event one was reported
by XIAO WU, and the earlier enabler-only fix did not address it.
Defer both the user_event_put() and the kfree(enabler) to a work item
queued with queue_rcu_work(), so they run only after an RCU grace period,
once all readers walking the enabler list have finished. The put must run
in process context because user_event_put() takes event_mutex on the last
reference, so a work queue is used rather than call_rcu(). The now-unlocked
put lets the locked argument of user_event_enabler_destroy() be removed;
all callers are updated. |
| The Extra Product Options Builder for WooCommerce WordPress plugin before 1.2.176 does not verify that the requester is entitled to a customer-uploaded file before serving it, allowing unauthenticated users who obtain a file's stored name to retrieve it.
The Extra Product Options Builder for WooCommerce WordPress plugin before 1.2.176 writes a deny-all rule into its upload directories, so the disclosure only crosses a boundary on web servers that honour it, such as Apache. Where it is ignored, as on a default nginx setup, the same files are already served at their direct URL and the endpoint exposes nothing further. |
| In the Linux kernel, the following vulnerability has been resolved:
ASoC: codecs: simple-mux: Fix enum control bounds check
simple_mux_control_put() rejects values greater than e->items, but
enum control values are zero based. For the two-entry mux used by this
driver, valid values are 0 and 1, so value 2 must be rejected as well.
Accepting e->items can store an invalid mux state, pass it to the GPIO
setter, and pass it on to the DAPM mux update path where it is used as
an index into the enum text array.
Use the same >= e->items check used by the ASoC enum helpers. |
| In the Linux kernel, the following vulnerability has been resolved:
mac802154: remove interfaces with RCU list deletion
Queue wake, stop, and disable paths walk local->interfaces under RCU.
The bulk hardware teardown path removes entries with list_del(), so an
asynchronous transmit completion can follow a poisoned list node in
ieee802154_wake_queue().
Use list_del_rcu() as in the single-interface removal path. The following
unregister_netdevice() waits for in-flight RCU readers before freeing the
netdevice, so no separate grace-period wait is needed. |
| In the Linux kernel, the following vulnerability has been resolved:
scsi: target: core: Fix iSCSI ISID use-after-free in REGISTER AND MOVE
core_scsi3_emulate_pro_register_and_move() maps the PERSISTENT RESERVE OUT
parameter list with transport_kmap_data_sg() and parses the destination
TransportID with target_parse_pr_out_transport_id(). For an iSCSI
TransportID (FORMAT CODE 01b), iscsi_parse_pr_out_transport_id() returns
the ISID in iport_ptr as a raw pointer into that mapped buffer.
The function then unmaps the buffer with transport_kunmap_data_sg() before
dereferencing iport_ptr in strcmp(), __core_scsi3_locate_pr_reg() and
core_scsi3_alloc_registration(). When the parameter list spans more than
one page (PARAMETER LIST LENGTH > 4096), transport_kmap_data_sg() uses
vmap() and transport_kunmap_data_sg() does vunmap(), so the kernel virtual
address backing iport_ptr is torn down and every subsequent dereference is
a use-after-free read of the unmapped region.
Keep the parameter list mapped until iport_ptr is no longer needed: drop
the early transport_kunmap_data_sg() and unmap once on the success path,
right before returning. The error paths already unmap through the existing
"if (buf) transport_kunmap_data_sg(cmd)" at the out: label, which now runs
on every post-map error exit because buf is no longer cleared early. Only
reads of the mapping happen while spinlocks are held; the map and unmap
calls remain outside any lock. The sibling caller
core_scsi3_decode_spec_i_port() already uses the buffer before unmapping it
and is left unchanged. |
| In the Linux kernel, the following vulnerability has been resolved:
accel/ivpu: Reject firmware log with size smaller than header
fw_log_from_bo() validates the tracing buffer header_size and that the
log fits within the BO, but never checks that log->size is at least
log->header_size. fw_log_print_buffer() then computes:
u32 data_size = log->size - log->header_size;
which underflows to a near-U32_MAX value when firmware reports a log whose
size is smaller than its header. That huge data_size defeats the
log_start/log_end bounds clamps added by commit dd1311bcf0e6 ("accel/ivpu:
Add bounds checks for firmware log indices"), so fw_log_print_lines() reads
far past the small real data region of the BO. A size of 0 also makes
fw_log_from_bo() advance the offset by 0, causing the callers to loop
forever on the same header.
Reject logs whose size is smaller than the header (which also rejects
size == 0). |
| In the Linux kernel, the following vulnerability has been resolved:
dma-fence: Make dma_fence_dedup_array() robust against 0-count input
dma_fence_dedup_array() returns 1 when called with num_fences == 0:
the for-loop body never executes, j stays at 0, and the final
`return ++j` yields 1. This contradicts both the kernel-doc ("Return:
Number of unique fences remaining in the array") and the natural
expectation that 0 input gives 0 output.
The caller __dma_fence_unwrap_merge() bails out via the
`if (count == 0 || count == 1)` fast path and so is save.
But amdgpu_userq_wait_*() could reach the dedup call with a zero local
count and dereference an uninitialized fence slot in the array.
Make the contract match the documentation by returning 0 early. This
also skips an unnecessary sort() call on an empty array. |
| In the Linux kernel, the following vulnerability has been resolved:
dm era: fix out-of-bounds memory access for non-zero start sector
dm-era tracks writes in target-relative blocks, but era_map() calculates
the writeset block before applying the target offset. Tables with a
non-zero start sector can therefore pass an absolute mapped-device block
to metadata_current_marked().
If the absolute block is beyond the current writeset size,
writeset_marked() tests past the end of the in-core bitset. KASAN reports
this as a vmalloc-out-of-bounds access.
Apply the target offset before calculating the era block so writeset
lookups use the target-relative block number. |
| The Simple JWT Login WordPress plugin before 3.6.8 does not validate the audience of the Google identity tokens it accepts, allowing unauthenticated users to authenticate as any user whose email address such a token carries, up to and including an administrator. Every site with the Simple JWT Login WordPress plugin before 3.6.8's Google sign-in enabled is affected. |
| The WPvivid — Backup, Migration & Staging WordPress plugin before 0.9.131 does not sanitise a value taken from an unauthenticated request before using it to build a log file path, allowing an attacker holding a site to site transfer key to create a log file in any existing writable directory of the site, including the web root.
The file name always carries a fixed suffix and the contents are always the WPvivid — Backup, Migration & Staging WordPress plugin before 0.9.131's own log header, so only the location of the file is attacker controlled. |
| An issue in Tneda W20E v.16.01.0.6(2782) allows a remote attacker to execute arbitrary code via the url_need_login function |
| Buffer Overflow vulnerability in SteelSeries GG (macOS) v.107.0.0 allows a remote attacker to execute arbitrary code via the libSSEdevice.dylib, dup_wcs components |
| A flaw was found in libssh. If data packets are processed after a channel is closed, channel data callbacks can be invoked after the associated data has already been freed, leading to crashes or possible use-after-free conditions. |
| A flaw was found in libssh. A malicious SFTP server can send responses for unknown request IDs that libssh clients keep queued indefinitely, causing unbounded memory growth and client-side denial of service. |
| A flaw was found in libssh. Incorrect AES-GCM finalization checks in builds using the OpenSSL backend can effectively remove integrity protection, allowing an in-path attacker to modify plaintext on the wire without detection. |
| A flaw was found in libssh. When ProxyCommand is used, an unchecked fork() failure can be stored as process ID -1; during cleanup, signals may then be sent across the caller's accessible process tree, leading to local denial of service. |
| A flaw was found in libssh. A remote authenticated client can issue SSH_FXP_READ requests with an arbitrarily large length, causing a libssh SFTP server to allocate excessive memory and potentially exhaust it through repeated requests. |
| A flaw was found in libssh. A remote authenticated peer can advertise a zero maximum packet size in SSH_MSG_CHANNEL_OPEN, causing later channel writes to loop indefinitely and consume CPU, leading to denial of service. |
