CVSS v3.1 |
| A improper access control vulnerability in Fortinet FortiClientEMS 7.4.5 through 7.4.6 may allow an unauthenticated attacker to execute unauthorized code or commands via crafted requests. |
| Totara LMS v19.1.5 and before is vulnerable to HTML Injection. An attacker can inject malicious HTML code in a message and send it to all the users in the application, resulting in executing the code and may lead to session hijacking and executing commands on the victim's browser. NOTE: The supplier states that the product name is Totara Learning and that the functionality referenced is the in app messaging client. They note that the in app messaging client only has the ability to embed a specific allowed list of HTML tags commonly used for text enhancement, which includes italic, bold, underline, strong, etc. Last, they state that the in app messaging client cannot embed <script>, <style>, <iframe>, <object>, <embed>, <form>, <input>, <button>, <svg>, <math>, etc., and any attempt to embed tags or attributes outside of the allowed list (including onerror, onaction, etc.) is sanitized via DOMPurify. |
| In the Linux kernel, the following vulnerability has been resolved:
netfilter: nf_conntrack_expect: use expect->helper
Use expect->helper in ctnetlink and /proc to dump the helper name.
Using nfct_help() without holding a reference to the master conntrack
is unsafe.
Use exp->master->helper in ctnetlink path if userspace does not provide
an explicit helper when creating an expectation to retain the existing
behaviour. The ctnetlink expectation path holds the reference on the
master conntrack and nf_conntrack_expect lock and the nfnetlink glue
path refers to the master ct that is attached to the skb. |
| Tenda W30E V2.0 V16.01.0.21 was found to contain a command injection vulnerability in the formSetUSBPartitionUmount function via the usbPartitionName parameter. This vulnerability allows attackers to execute arbitrary commands via a crafted request. |
| A vulnerability was detected in SourceCodester Pizzafy Ecommerce System 1.0. Affected is the function delete_category of the file /admin/ajax.php?action=delete_category. The manipulation of the argument ID results in sql injection. The attack can be launched remotely. The exploit is now public and may be used. |
| A flaw was found in libsoup. An integer underflow vulnerability occurs when processing content with a zero-length resource, leading to a buffer overread. This can allow an attacker to potentially access sensitive information or cause an application level denial of service. |
| Vulnerability in Spring Spring Security. If an application is using securityMatchers(String) and a PathPatternRequestMatcher.Builder bean to prepend a servlet path, matching requests to that filter chain may fail and its related security components will not be exercised as intended by the application. This can lead to the authentication, authorization, and other security controls being rendered inactive on intended requests.This issue affects Spring Security: from 7.0.0 through 7.0.4. |
| Vulnerability in Spring Spring Security. If an application uses <sec:intercept-url servlet-path="/servlet-path" pattern="/endpoint/**"/> to define the servlet path for computing a path matcher, then the servlet path is not included and the related authorization rules are not exercised. This can lead to an authorization bypass.This issue affects Spring Security: from 7.0.0 through 7.0.4. |
| A zone transition from NSEC to NSEC3 might trigger an internal inconsistency and cause a denial of service. |
| In the Linux kernel, the following vulnerability has been resolved:
netfs: Fix read abandonment during retry
Under certain circumstances, all the remaining subrequests from a read
request will get abandoned during retry. The abandonment process expects
the 'subreq' variable to be set to the place to start abandonment from, but
it doesn't always have a useful value (it will be uninitialised on the
first pass through the loop and it may point to a deleted subrequest on
later passes).
Fix the first jump to "abandon:" to set subreq to the start of the first
subrequest expected to need retry (which, in this abandonment case, turned
out unexpectedly to no longer have NEED_RETRY set).
Also clear the subreq pointer after discarding superfluous retryable
subrequests to cause an oops if we do try to access it. |
| In the Linux kernel, the following vulnerability has been resolved:
netfs: Fix kernel BUG in netfs_limit_iter() for ITER_KVEC iterators
When a process crashes and the kernel writes a core dump to a 9P
filesystem, __kernel_write() creates an ITER_KVEC iterator. This
iterator reaches netfs_limit_iter() via netfs_unbuffered_write(), which
only handles ITER_FOLIOQ, ITER_BVEC and ITER_XARRAY iterator types,
hitting the BUG() for any other type.
Fix this by adding netfs_limit_kvec() following the same pattern as
netfs_limit_bvec(), since both kvec and bvec are simple segment arrays
with pointer and length fields. Dispatch it from netfs_limit_iter() when
the iterator type is ITER_KVEC. |
| In the Linux kernel, the following vulnerability has been resolved:
ext4: fix use-after-free in update_super_work when racing with umount
Commit b98535d09179 ("ext4: fix bug_on in start_this_handle during umount
filesystem") moved ext4_unregister_sysfs() before flushing s_sb_upd_work
to prevent new error work from being queued via /proc/fs/ext4/xx/mb_groups
reads during unmount. However, this introduced a use-after-free because
update_super_work calls ext4_notify_error_sysfs() -> sysfs_notify() which
accesses the kobject's kernfs_node after it has been freed by kobject_del()
in ext4_unregister_sysfs():
update_super_work ext4_put_super
----------------- --------------
ext4_unregister_sysfs(sb)
kobject_del(&sbi->s_kobj)
__kobject_del()
sysfs_remove_dir()
kobj->sd = NULL
sysfs_put(sd)
kernfs_put() // RCU free
ext4_notify_error_sysfs(sbi)
sysfs_notify(&sbi->s_kobj)
kn = kobj->sd // stale pointer
kernfs_get(kn) // UAF on freed kernfs_node
ext4_journal_destroy()
flush_work(&sbi->s_sb_upd_work)
Instead of reordering the teardown sequence, fix this by making
ext4_notify_error_sysfs() detect that sysfs has already been torn down
by checking s_kobj.state_in_sysfs, and skipping the sysfs_notify() call
in that case. A dedicated mutex (s_error_notify_mutex) serializes
ext4_notify_error_sysfs() against kobject_del() in ext4_unregister_sysfs()
to prevent TOCTOU races where the kobject could be deleted between the
state_in_sysfs check and the sysfs_notify() call. |
| In the Linux kernel, the following vulnerability has been resolved:
ext4: validate p_idx bounds in ext4_ext_correct_indexes
ext4_ext_correct_indexes() walks up the extent tree correcting
index entries when the first extent in a leaf is modified. Before
accessing path[k].p_idx->ei_block, there is no validation that
p_idx falls within the valid range of index entries for that
level.
If the on-disk extent header contains a corrupted or crafted
eh_entries value, p_idx can point past the end of the allocated
buffer, causing a slab-out-of-bounds read.
Fix this by validating path[k].p_idx against EXT_LAST_INDEX() at
both access sites: before the while loop and inside it. Return
-EFSCORRUPTED if the index pointer is out of range, consistent
with how other bounds violations are handled in the ext4 extent
tree code. |
| In the Linux kernel, the following vulnerability has been resolved:
mm/pagewalk: fix race between concurrent split and refault
The splitting of a PUD entry in walk_pud_range() can race with a
concurrent thread refaulting the PUD leaf entry causing it to try walking
a PMD range that has disappeared.
An example and reproduction of this is to try reading numa_maps of a
process while VFIO-PCI is setting up DMA (specifically the
vfio_pin_pages_remote call) on a large BAR for that process.
This will trigger a kernel BUG:

Fix this by validating the PUD entry in walk_pmd_range() using a stable
snapshot (pudp_get()). If the PUD is not present or is a leaf, retry the
walk via ACTION_AGAIN instead of descending further. This mirrors the
retry logic in walk_pte_range(), which lets walk_pmd_range() retry if the
PTE is not being got by pte_offset_map_lock(). |
| Improper Verification of Cryptographic Signature (CWE-347) in Elastic Package Registry could allow an attacker positioned to intercept network traffic, or to otherwise influence the contents served to a self-hosted registry, to substitute a tampered package without the integrity check failing closed. |
| Snap One WattBox 800 and 820 series firmware versions prior to 2.10.0.0 contain undisclosed diagnostic HTTP endpoints that require only the device MAC address and service tag for authentication, both of which are printed in plaintext on the physical device label. Attackers with access to the device label or documentation containing these values can authenticate to the several endpoints and execute arbitrary commands as root on the device. |
| A flaw has been found in elinsky execution-system-mcp 0.1.0. The impacted element is the function _get_context_file_path of the file src/execution_system_mcp/server.py of the component add_action Tool. This manipulation of the argument context causes path traversal. The attack can be initiated remotely. The exploit has been published and may be used. |
| In the Linux kernel, the following vulnerability has been resolved:
ksmbd: do not expire session on binding failure
When a multichannel session binding request fails (e.g. wrong password),
the error path unconditionally sets sess->state = SMB2_SESSION_EXPIRED.
However, during binding, sess points to the target session looked up via
ksmbd_session_lookup_slowpath() -- which belongs to another connection's
user. This allows a remote attacker to invalidate any active session by
simply sending a binding request with a wrong password (DoS).
Fix this by skipping session expiration when the failed request was
a binding attempt, since the session does not belong to the current
connection. The reference taken by ksmbd_session_lookup_slowpath() is
still correctly released via ksmbd_user_session_put(). |

Which seems to hint that the vma we are re-inserting for the ops unwind
is either invalid or overlapping with something already inserted in the
vm. It shouldn't be invalid since this is a re-insertion, so must have
worked before. Leaving the likely culprit as something already placed
where we want to insert the vma.
Following from that, for the case where we do something like a rebind in
the middle of a vma, and one or both mapped ends are already compatible,
we skip doing the rebind of those vma and set next/prev to NULL. As well
as then adjust the original unmap va range, to avoid unmapping the ends.
However, if we trigger the unwind path, we end up with three va, with
the two ends never being removed and the original va range in the middle
still being the shrunken size.
If this occurs, one failure mode is when another unwind op needs to
interact with that range, which can happen with a vector of binds. For
example, if we need to re-insert something in place of the original va.
In this case the va is still the shrunken version, so when removing it
and then doing a re-insert it can overlap with the ends, which were
never removed, triggering a warning like above, plus leaving the vm in a
bad state.
With that, we need two things here:
1) Stop nuking the prev/next tracking for the skip cases. Instead
relying on checking for skip prev/next, where needed. That way on the
unwind path, we now correctly remove both ends.
2) Undo the unmap va shrinkage, on the unwind path. With the two ends
now removed the unmap va should expand back to the original size again,
before re-insertion.
v2:
- Update the explanation in the commit message, based on an actual IGT of
triggering this issue, rather than conjecture.
- Also undo the unmap shrinkage, for the skip case. With the two ends
now removed, the original unmap va range should expand back to the
original range.
v3:
- Track the old start/range separately. vma_size/start() uses the va
info directly.

spi: use generic driver_override infrastructure
When a driver is probed through __driver_attach(), the bus' match()
callback is called without the device lock held, thus accessing the
driver_override field without a lock, which can cause a UAF.
Fix this by using the driver-core driver_override infrastructure taking
care of proper locking internally.
Note that calling match() from __driver_attach() without the device lock
held is intentional. [1]
Also note that we do not enable the driver_override feature of struct
bus_type, as SPI - in contrast to most other buses - passes "" to
sysfs_emit() when the driver_override pointer is NULL. Thus, printing
"\n" instead of "(null)\n". |
