| In the Linux kernel, the following vulnerability has been resolved:
ksmbd: fix null pointer dereference in compare_guid_key()
session_fd_check() walks the per-inode m_op_list during durable-handle
session teardown and sets op->conn = NULL for every opinfo whose conn
matched the closing session's connection. The matching opinfo, however,
stays linked in its per-ClientGuid lease_table_list entry's lb->lease_list
because destroy_lease_table() only runs on full TCP-connection teardown,
not on SESSION_LOGOFF.
If the same TCP connection then negotiates a fresh session with the
same ClientGuid (ClientGuid is bound to NEGOTIATE, not the session, and
is unchanged across LOGOFF + SETUP) and issues a SMB2 CREATE with a
lease context on a different inode, find_same_lease_key() walks
lb->lease_list, reaches the stale opinfo, and calls compare_guid_key(),
which unconditionally dereferences opinfo->conn->ClientGUID. The conn
pointer is NULL and the kernel panics.
Reproducer requires only a successful SMB2 SESSION_SETUP and a share
configured with 'durable handles = yes'. KASAN report on mainline
70390501d194:
general protection fault, probably for non-canonical address
0xdffffc0000000069: 0000 [#1] SMP KASAN PTI
KASAN: null-ptr-deref in range [0x0000000000000348-0x000000000000034f]
Workqueue: ksmbd-io handle_ksmbd_work
RIP: 0010:bcmp+0x5b/0x230
Call Trace:
compare_guid_key+0x4b/0xd0
find_same_lease_key+0x324/0x690
smb2_open+0x6aea/0x8e60
handle_ksmbd_work+0x796/0xee0
...
Faulting address 0x348 is the offset of ClientGUID within struct
ksmbd_conn, confirming opinfo->conn was NULL.
Read opinfo->conn once and bail out if it has been cleared by a
concurrent session_fd_check(). A half-detached opinfo cannot be the
owner of an active lease, so returning 0 is the correct match result. |
| In the Linux kernel, the following vulnerability has been resolved:
xfs: resample the data fork mapping after cycling ILOCK
xfs_reflink_fill_{cow_hole,delalloc} are both presented with an inode,
a data fork mapping, and a cow fork mapping. Unfortunately, these two
helpers cycle the ILOCK to grab a transaction, which means that the
mappings are stale as soon as we reacquire the ILOCK. Currently we
refresh the cow fork mapping by re-calling xfs_find_trim_cow_extent, but
we don't refresh the data fork mapping beforehand, which means that the
xfs_bmap_trim_cow in that function queries the refcount btree about the
wrong physical blocks and returns an inaccurate value in *shared.
If *shared is now false, the directio write proceeds with a stale data
fork mapping. Fix this by querying the data fork mapping if the
sequence counter changes across the ILOCK cycle. |
| In the Linux kernel, the following vulnerability has been resolved:
rxrpc: Fix RxGK token loading to check bounds
rxrpc_preparse_xdr_yfs_rxgk() reads the raw key length and ticket length
from the XDR token as u32 values and passes each through round_up(x, 4)
before using the rounded value for validation and allocation. When the raw
length is >= 0xfffffffd, round_up() wraps to 0, so the bounds check and
kzalloc both use 0 while the subsequent memcpy still copies the original
~4 GiB value, producing a heap buffer overflow reachable from an
unprivileged add_key() call.
Fix this by:
(1) Rejecting raw key lengths above AFSTOKEN_GK_KEY_MAX and raw ticket
lengths above AFSTOKEN_GK_TOKEN_MAX before rounding, consistent with
the caps that the RxKAD path already enforces via AFSTOKEN_RK_TIX_MAX.
(2) Sizing the flexible-array allocation from the validated raw key
length via struct_size_t() instead of the rounded value.
(3) Caching the raw lengths so that the later field assignments and
memcpy calls do not re-read from the token, eliminating a class of
TOCTOU re-parse.
The control path (valid token with lengths within bounds) is unaffected. |
| A vulnerability was identified in code-projects Task Management System 1.0. This affects the function Operation::select_with_multiple_condition of the file /index.php of the component Login Form. Such manipulation of the argument email leads to sql injection. It is possible to launch the attack remotely. The exploit is publicly available and might be used. |
| IBM Storage Scale 5.2.3.0 through 5.2.3.8, and 6.0.0.0 through 6.0.1.0 Secrets may be disclosed in log files in IBM Storage Scale Management GUI The admin password is logged into the GUI log of IBM Storage Scale Systems Deploy and Upgrade from GUI. Secrets may be disclosed in information related to exceptions in IBM Storage Scale Management GUI. |
| Heap-based buffer overflow in Windows DNS allows an authorized attacker to elevate privileges locally. |
| Improper Neutralization of CRLF Sequences ('CRLF Injection') vulnerability in ninenines cowlib allows HTTP request splitting and cookie smuggling via unvalidated cookie name and value fields.
cow_cookie:cookie/1 in cowlib builds a client-side Cookie: request header from a list of name-value pairs without validating either field. An attacker who controls the cookie names or values passed to this function can inject ;, ,, CR, LF, or TAB characters into the serialized header. This enables two classes of attack: cookie smuggling within a single header (e.g. injecting ; admin=1 to introduce a phantom cookie that the receiving server treats as authentic) and HTTP request header splitting (injecting CRLF to append arbitrary headers or smuggle a complete second request against a shared upstream proxy). The decoder side (parse_cookie_name/1, parse_cookie_value/1) and setcookie/3 already validate and reject these characters; the encoder alone is missing the check.
This issue affects cowlib: from 2.9.0 onward. |
| DOMPurify before 3.4.13 contains a cross-site scripting vulnerability in IN_PLACE sanitization where element-removal hooks fail to neutralize detached subtrees. Attackers can supply HTML with event handlers on descendant elements that execute after sanitization completes, even though the returned root appears clean. |
| Grav before 2.0.14 contains a stored cross-site scripting vulnerability in the Security::detectXss() function (system/src/Grav/Common/Security.php). All XSS detection patterns use the PCRE /u (UTF-8) modifier, so a single invalid UTF-8 byte anywhere in page content causes preg_match() to return false for every pattern, silently bypassing the save-time XSS safety gate (Validation::checkSafety()). An authenticated attacker with page-edit permissions (without the security.xss_whitelist privilege) can store malicious JavaScript that executes in the browser of a visitor who views the affected page. |
| grav-plugin-api versions before 1.0.15 fail to validate Twig content in the translate() endpoint, allowing attackers with api.pages.write permission to persist pages with process.twig enabled. Attackers can submit crafted header and content parameters to execute server-side template injection payloads that are evaluated at render time. |
| phpMyFAQ before 4.1.6 contains a privilege escalation vulnerability in GroupController::updateMembers() that allows administrators with only group-management permissions to join privileged groups without verification of required rights. Attackers can add themselves to pre-existing groups holding user-management rights and immediately inherit those permissions to modify or delete user accounts. |
| Dell Wyse Management Suite (WMS), versions prior to 2605.0.2, contain an Unrestricted Upload of File with Dangerous Type vulnerability. A high privileged attacker with remote access could potentially exploit this vulnerability, leading to Remote Code Execution. |
| A vulnerability was found in karakeep-app karakeep up to 0.32.0. The affected element is the function authorize of the file apps/web/server/auth.ts of the component Login Endpoint. The manipulation results in improper restriction of excessive authentication attempts. The attack may be performed from remote. This attack is characterized by high complexity. The exploitability is described as difficult. The exploit has been made public and could be used. Upgrading to version 0.33.0 is sufficient to fix this issue. The patch is identified as f7d042971d0d2bcc7119654830cf1eb93eabbf24. It is advisable to upgrade the affected component. |
| A security vulnerability has been detected in OpenBoxes up to 0.9.1. This issue affects the function DocumentController of the file grails-app/controllers/org/pih/warehouse/core/DocumentController.groovy of the component Document Upload Controller. The manipulation leads to unrestricted upload. It is possible to initiate the attack remotely. The exploit has been disclosed publicly and may be used. Upgrading to version 0.9.2 is capable of addressing this issue. The identifier of the patch is e945d6bfcec29642f514e7d298dfba2cc6cd7cd4. Upgrading the affected component is recommended. |

| calibre is an e-book manager. Prior to 9.10.0, a malicious EPUB, OPF, or PDF file can execute arbitrary Python code when its metadata is read by calibre, including through Add books or Edit books, by embedding a custom column definition with a python: template in calibre:user_metadata that is passed unsanitized to exec() in the template formatter. This issue is fixed in version 9.10.0. |
| In the Linux kernel, the following vulnerability has been resolved:
fbcon: fix NULL pointer dereference for a console without vc_data
fbcon_new_modelist() runs when a framebuffer's modelist changes. For each
console mapped to it with fb_display[i].mode set, it reads vc_cons[i].d and
passes the vc_num to fbcon_set_disp(). This assumes a console with a mode
set has a vc_data, but it can be NULL. fbcon_set_disp() sets
fb_display[i].mode before it checks vc_data, and fbcon_deinit() leaves the
mode set after the vc_data is freed. fbcon_new_modelist() then dereferences
the NULL vc_data.
Keep fb_display[i].mode set only while the console has a vc_data. Check
vc_data before setting the mode in fbcon_set_disp(), and clear the mode in
fbcon_deinit(). The existing mode check in fbcon_new_modelist() then skips
such consoles. |
| In the Linux kernel, the following vulnerability has been resolved:
selinux: check connect-related permissions on TCP Fast Open
Similar to Landlock, SELinux was not updated when TCP Fast Open
support was introduced to ensure connect-related permissions are
checked when using TCP Fast Open. Update its socket_sendmsg() hook to
call selinux_socket_connect() when MSG_FASTOPEN is passed. |
| In the Linux kernel, the following vulnerability has been resolved:
ntfs: add bounds check before accessing EA entries
in ntfs_ea_lookup and ntfs_listxattr, this verifies that there is enough
space in the EA entry before accessing the next_entry_offset field of
the EA entry. |
| In the Linux kernel, the following vulnerability has been resolved:
ntfs: not change 0-byte $DATA attribute to non-resident
When ntfs_resident_attr_resize() cannot grow a resident attribute in
place, it retries after converting other resident attributes to
non-resident to free space in the MFT recrord.
Do not select zero-length resident $DATA attributes for this conversion.
fsck treats 0-byte non-resident $DATA attribute as corruptions. |
