| In the Linux kernel, the following vulnerability has been resolved:
scsi: fnic: Fix crash in fnic_wq_cmpl_handler when FDMI times out
When both the RHBA and RPA FDMI requests time out, fnic reuses a frame to
send ABTS for each of them. On send completion, this causes an attempt to
free the same frame twice that leads to a crash.
Fix crash by allocating separate frames for RHBA and RPA, and modify ABTS
logic accordingly.
Tested by checking MDS for FDMI information.
Tested by using instrumented driver to:
- Drop PLOGI response
- Drop RHBA response
- Drop RPA response
- Drop RHBA and RPA response
- Drop PLOGI response + ABTS response
- Drop RHBA response + ABTS response
- Drop RPA response + ABTS response
- Drop RHBA and RPA response + ABTS response for both of them |

The reason is simple, readahead brought some order 0 folio in swap cache,
and the swapin mTHP folio being allocated is in conflict with it, so
swapcache_prepare fails and causes shmem_swap_alloc_folio to return
-EEXIST, and shmem simply retries again and again causing this loop.
Fix it by applying a similar fix for anon mTHP swapin.
The performance change is very slight, time of swapin 10g zero folios
with shmem (test for 12 times):
Before: 2.47s
After: 2.48s

| In the Linux kernel, the following vulnerability has been resolved:
mm: userfaultfd: fix race of userfaultfd_move and swap cache
This commit fixes two kinds of races, they may have different results:
Barry reported a BUG_ON in commit c50f8e6053b0, we may see the same
BUG_ON if the filemap lookup returned NULL and folio is added to swap
cache after that.
If another kind of race is triggered (folio changed after lookup) we
may see RSS counter is corrupted:
[ 406.893936] BUG: Bad rss-counter state mm:ffff0000c5a9ddc0
type:MM_ANONPAGES val:-1
[ 406.894071] BUG: Bad rss-counter state mm:ffff0000c5a9ddc0
type:MM_SHMEMPAGES val:1
Because the folio is being accounted to the wrong VMA.
I'm not sure if there will be any data corruption though, seems no.
The issues above are critical already.
On seeing a swap entry PTE, userfaultfd_move does a lockless swap cache
lookup, and tries to move the found folio to the faulting vma. Currently,
it relies on checking the PTE value to ensure that the moved folio still
belongs to the src swap entry and that no new folio has been added to the
swap cache, which turns out to be unreliable.
While working and reviewing the swap table series with Barry, following
existing races are observed and reproduced [1]:
In the example below, move_pages_pte is moving src_pte to dst_pte, where
src_pte is a swap entry PTE holding swap entry S1, and S1 is not in the
swap cache:
CPU1 CPU2
userfaultfd_move
move_pages_pte()
entry = pte_to_swp_entry(orig_src_pte);
// Here it got entry = S1
... < interrupted> ...
<swapin src_pte, alloc and use folio A>
// folio A is a new allocated folio
// and get installed into src_pte
<frees swap entry S1>
// src_pte now points to folio A, S1
// has swap count == 0, it can be freed
// by folio_swap_swap or swap
// allocator's reclaim.
<try to swap out another folio B>
// folio B is a folio in another VMA.
<put folio B to swap cache using S1 >
// S1 is freed, folio B can use it
// for swap out with no problem.
...
folio = filemap_get_folio(S1)
// Got folio B here !!!
... < interrupted again> ...
<swapin folio B and free S1>
// Now S1 is free to be used again.
<swapout src_pte & folio A using S1>
// Now src_pte is a swap entry PTE
// holding S1 again.
folio_trylock(folio)
move_swap_pte
double_pt_lock
is_pte_pages_stable
// Check passed because src_pte == S1
folio_move_anon_rmap(...)
// Moved invalid folio B here !!!
The race window is very short and requires multiple collisions of multiple
rare events, so it's very unlikely to happen, but with a deliberately
constructed reproducer and increased time window, it can be reproduced
easily.
This can be fixed by checking if the folio returned by filemap is the
valid swap cache folio after acquiring the folio lock.
Another similar race is possible: filemap_get_folio may return NULL, but
folio (A) could be swapped in and then swapped out again using the same
swap entry after the lookup. In such a case, folio (A) may remain in the
swap cache, so it must be moved too:
CPU1 CPU2
userfaultfd_move
move_pages_pte()
entry = pte_to_swp_entry(orig_src_pte);
// Here it got entry = S1, and S1 is not in swap cache
folio = filemap_get

| In the Linux kernel, the following vulnerability has been resolved:
btrfs: fix invalid inode pointer dereferences during log replay
In a few places where we call read_one_inode(), if we get a NULL pointer
we end up jumping into an error path, or fallthrough in case of
__add_inode_ref(), where we then do something like this:
iput(&inode->vfs_inode);
which results in an invalid inode pointer that triggers an invalid memory
access, resulting in a crash.
Fix this by making sure we don't do such dereferences. |

| In danny-avila/librechat version 0.7.9, there is an insecure API design issue in the 2-Factor Authentication (2FA) flow. The system allows users to disable 2FA without requiring a valid OTP or backup code, bypassing the intended verification process. This vulnerability occurs because the backend does not properly validate the OTP or backup code when the API endpoint '/api/auth/2fa/disable' is directly accessed. This flaw can be exploited by authenticated users to weaken the security of their own accounts, although it does not lead to full account compromise. |
| Notepad++ v8.8.3 has a DLL hijacking vulnerability, which can replace the original DLL file to execute malicious code. NOTE: this is disputed by multiple parties because the behavior only occurs when a user installs the product into a directory tree that allows write access by arbitrary unprivileged users. |
| A vulnerability in the RADIUS setting Reject RADIUS requests from clients with repeated failures on Cisco Identity Services Engine (ISE) could allow an unauthenticated, remote attacker to cause Cisco ISE to restart unexpectedly.
This vulnerability is due to a logic error when processing a RADIUS access request for a MAC address that is already a rejected endpoint. An attacker could exploit this vulnerability by sending a specific sequence of multiple crafted RADIUS access request messages to Cisco ISE. A successful exploit could allow the attacker to cause a denial of service (DoS) condition when Cisco ISE restarts. |
| Directus is a real-time API and App dashboard for managing SQL database content. A stored cross-site scripting (XSS) vulnerability exists in versions prior to 11.13.0 that allows users with `upload files` and `edit item` permissions to inject malicious JavaScript through the Block Editor interface. Attackers can bypass Content Security Policy (CSP) restrictions by combining file uploads with iframe srcdoc attributes, resulting in persistent XSS execution. Version 11.13.0 fixes the issue. |
| Directus is a real-time API and App dashboard for managing SQL database content. The Comment feature has implemented a filter to prevent users from adding restricted characters, such as HTML tags. However, this filter operates on the client-side, which can be bypassed, making the application vulnerable to HTML Injection. This vulerability is fixed in 10.13.4 and 11.2.0. |
| A flaw was found in Red Hat Openshift AI Service. The TrustyAI component is granting all service accounts and users on a cluster permissions to get, list, watch any pod in any namespace on the cluster.
TrustyAI is creating a role `trustyai-service-operator-lmeval-user-role` and a CRB `trustyai-service-operator-default-lmeval-user-rolebinding` which is being applied to `system:authenticated` making it so that every single user or service account can get a list of pods running in any namespace on the cluster
Additionally users can access all `persistentvolumeclaims` and `lmevaljobs` |
| In the Linux kernel, the following vulnerability has been resolved:
iommu: Fix two issues in iommu_copy_struct_from_user()
In the review for iommu_copy_struct_to_user() helper, Matt pointed out that
a NULL pointer should be rejected prior to dereferencing it:
https://lore.kernel.org/all/86881827-8E2D-461C-BDA3-FA8FD14C343C@nvidia.com
And Alok pointed out a typo at the same time:
https://lore.kernel.org/all/480536af-6830-43ce-a327-adbd13dc3f1d@oracle.com
Since both issues were copied from iommu_copy_struct_from_user(), fix them
first in the current header. |
| In the Linux kernel, the following vulnerability has been resolved:
powerpc64/ftrace: fix module loading without patchable function entries
get_stubs_size assumes that there must always be at least one patchable
function entry, which is not always the case (modules that export data
but no code), otherwise it returns -ENOEXEC and thus the section header
sh_size is set to that value. During module_memory_alloc() the size is
passed to execmem_alloc() after being page-aligned and thus set to zero
which will cause it to fail the allocation (and thus module loading) as
__vmalloc_node_range() checks for zero-sized allocs and returns null:
[ 115.466896] module_64: cast_common: doesn't contain __patchable_function_entries.
[ 115.469189] ------------[ cut here ]------------
[ 115.469496] WARNING: CPU: 0 PID: 274 at mm/vmalloc.c:3778 __vmalloc_node_range_noprof+0x8b4/0x8f0

[ 115.478574] ---[ end trace 0000000000000000 ]---
[ 115.479545] execmem: unable to allocate memory
Fix this by removing the check completely, since it is anyway not
helpful to propagate this as an error upwards. |
| In the Linux kernel, the following vulnerability has been resolved:
wifi: plfxlc: Remove erroneous assert in plfxlc_mac_release
plfxlc_mac_release() asserts that mac->lock is held. This assertion is
incorrect, because even if it was possible, it would not be the valid
behaviour. The function is used when probe fails or after the device is
disconnected. In both cases mac->lock can not be held as the driver is
not working with the device at the moment. All functions that use mac->lock
unlock it just after it was held. There is also no need to hold mac->lock
for plfxlc_mac_release() itself, as mac data is not affected, except for
mac->flags, which is modified atomically.
This bug leads to the following warning:

================================================================
Found by Linux Verification Center (linuxtesting.org) with Syzkaller. |
| An unauthenticated file download vulnerability exists in LimeSurvey versions from 2.0+ up to and including 2.06+ Build 151014. The application fails to validate serialized input to the admin backup endpoint (`index.php/admin/update/sa/backup`), allowing attackers to specify arbitrary file paths using a crafted `datasupdateinfo` payload. The files are packaged in a ZIP archive and made available for download without authentication. This vulnerability can be exploited to read arbitrary files on the host system, including sensitive OS and configuration files. |
| A remote code execution vulnerability exists in multiple Netcore and Netis routers models with firmware released prior to August 2014 due to the presence of an undocumented backdoor listener on UDP port 53413. Exact version boundaries remain undocumented. An unauthenticated remote attacker can send specially crafted UDP packets to execute arbitrary commands on the affected device. This backdoor uses a hardcoded authentication mechanism and accepts shell commands post-authentication. Some device models include a non-standard implementation of the `echo` command, which may affect exploitability. |
| A remote command execution vulnerability exists in IPFire before version 2.19 Core Update 101 via the 'proxy.cgi' CGI interface. An authenticated attacker can inject arbitrary shell commands through crafted values in the NCSA user creation form fields, leading to command execution with web server privileges. |
| An unauthenticated command injection vulnerability exists in VICIdial versions 2.9 RC1 through 2.13 RC1, within the vicidial_sales_viewer.php component when password encryption is enabled (a non-default configuration). The application improperly passes the HTTP Basic Authentication password directly to a call to exec() without adequate sanitation. This allows remote attackers to inject and execute arbitrary operating system commands as the web server user. NOTE: This vulnerability was mitigated in 2017. |
