CVSS v3.1 |
| A vulnerability was identified in krayin laravel-crm up to 2.2.5. This vulnerability affects the function ConfigurationForm::rules of the file packages/Webkul/Admin/src/Http/Requests/ConfigurationForm.php of the component Upload Functionality. The manipulation leads to cross site scripting. The attack is possible to be carried out remotely. The exploit is publicly available and might be used. Upgrading to version 2.2.6 is able to resolve this issue. The identifier of the patch is b9836530ec9f5ef0f51653bb0cbbc47ef7184f51. It is advisable to upgrade the affected component. |
| In the Linux kernel, the following vulnerability has been resolved:
tracing: Fix memory corruption from a "STACKTRACE" histogram key
"cpu", "CPU", "stacktrace" and "STACKTRACE" are generic fields, defined
with an offset and a size of zero so that the filter code can match them
by name. parse_field() maps them onto their common_* equivalents for
backward compatibility, but unlike the common_* names it hands the
placeholder back to the caller instead of NULL.
create_hist_field() takes a non-NULL field as a promise that the record
carries a stacktrace and picks HIST_FIELD_FN_STACK, so the __data_loc
word is read from offset 0, that is from common_type, and its low 16
bits are followed as an offset into the record. What is found there
becomes the length of an unbounded memcpy. Pick an event whose id is
small enough that the offset stays inside its own record and the length
is a kernel text address:
# cd /sys/kernel/tracing
# echo 'hist:keys=STACKTRACE' > events/ftrace/print/trigger
# echo hello > trace_marker
Oops: general protection fault, probably for non-canonical address

Kernel panic - not syncing: Fatal exception in interrupt
Leave the field NULL, which is what the comment above the branch says
the code does and what common_stacktrace already does. FILTER_CPU and
FILTER_COMM are left alone, their create_hist_field() branches never
look at the field. |
| In the Linux kernel, the following vulnerability has been resolved:
tracing: Fix memory corruption from the histogram stacktrace modifier
parse_field() sets HIST_FIELD_FL_STACKTRACE from the ".stacktrace"
modifier before it looks the field name up, and nothing afterwards
checks that the name resolved to a field which holds a stacktrace.
create_hist_field() picks HIST_FIELD_FN_STACK on the strength of the
field pointer alone, which reads a __data_loc word from the record and
follows its low 16 bits as an offset into the same record.
event_hist_trigger() takes the first word there as an entry count and
copies that many longs into a 31 entry array:
n_entries = *stack;
memcpy(entries, ++stack, n_entries * sizeof(unsigned long));
Neither end of that copy is bounded, and the count is whatever the event
holds at the offset, so any field will do:
# cd /sys/kernel/tracing/events/sched/sched_process_fork
# echo 'hist:keys=parent_pid.stacktrace' > trigger
# (true)
BUG: kernel NULL pointer dereference, address: 0000000000000008

The timer interrupt landed on the rbtree the copy had already run over.
No debug options are needed for this; KASAN reports the same write as an
out-of-bounds read of 13835058055416381440 bytes.
Documentation/trace/histogram.rst already states the rule, "must be a
long[] type", so enforce it once the name has been resolved. Names which
resolve to no field at all, "hitcount.stacktrace" and the common_*
pseudo-fields, are refused for the same reason: they hold no stacktrace
to read. |
| In the Linux kernel, the following vulnerability has been resolved:
ftrace: fork: Initialize function graph state before copy_exec_state()
dup_task_struct() copies the parent's task_struct, including ret_stack.
ftrace_graph_init_task() clears the copied function graph state, but it
currently runs after copy_exec_state().
For non-CLONE_VM forks, copy_exec_state() allocates a new task_exec_state.
If that allocation fails, copy_process() reaches bad_fork_free and
free_task() calls ftrace_graph_exit_task(). Since the child still carries
the parent's ret_stack pointer, the unwind frees the parent's active
function graph return stack. The parent subsequently accesses freed memory
from function_graph_enter_regs().

| In the Linux kernel, the following vulnerability has been resolved:
reboot: fix cad_pid use-after-free race
cad_pid is a single kernel-wide struct pid pointer. proc_do_cad_pid()
reads it and passes it to pid_vnr() without protecting the lifetime of
the referenced struct pid. A concurrent writer can replace cad_pid and
drop the final reference to the old struct pid after the reader has
loaded the pointer but before pid_vnr() has finished dereferencing it,
causing a use-after-free.
kill_cad_pid() has the same lifetime race when it passes cad_pid to
kill_pid().
At the time this issue was reported, an unprivileged user could reach the
sysctl through user and PID namespaces because cad_pid was registered in
pid_table[]. Moving cad_pid back to the global reboot sysctl table
corrected that namespace and permission mismatch, but did not fix the
underlying lifetime race.
Fix this by treating cad_pid as an RCU-protected pointer at both read
sites and by waiting for a grace period before dropping the old reference
on the write side.
call_rcu(&old_pid->rcu, ...) cannot be used here because free_pid()
also queues pid->rcu; queueing the same rcu_head twice can corrupt the
RCU callback list.
Original KASAN crash stack:
kernel/pid.c:545 pid_nr_ns() # reads freed pid->level
kernel/pid.c:556 pid_vnr() # calls pid_nr_ns()
kernel/pid.c:775 proc_do_cad_pid() # calls pid_vnr(cad_pid) |

x86/amd_node: Fix potential NULL pointer dereference
amd_smn_read/write() are exported functions around __amd_smn_rw(), so
they are always available even if amd_smn_init() fails. In that case,
'amd_roots' is NULL and __amd_smn_rw() will access uninitialized memory.
Then, commit:
83518453074d ("x86/amd_node: Add SMN offsets to exclusive region access")
added the 'smn_exclusive' flag, which indicated the calls to
pci_request_config_region_exclusive() succeeded, to prevent
concurrent userspace access.
Commit:
0a4b61d9c2e4 ("x86/amd_node: Fix AMD root device caching")
re-ordered initialization so pci_request_config_region_exclusive() is
called earlier and a failure exits amd_smn_init() before allocating
'amd_roots'. The setting of 'smn_exclusive' moved to the end of
amd_smn_init(), after 'amd_roots' is allocated. It became redundant
and can be removed.
Replace 'smn_exclusive' with directly checking 'amd_roots', to fix a
potential NULL pointer dereference and to simplify the logic.

| In the Linux kernel, the following vulnerability has been resolved:
configfs: pin the symlink target's dirent instead of chasing ->ci_dentry
create_link() reads the target's configfs_dirent from
item->ci_dentry->d_fsdata, relying on the item reference taken by
get_target(). That reference pins the item, not its dentry: the dentry is
pinned by DCACHE_PERSISTENT, which configfs_remove_dir() releases via
simple_rmdir() while the item is still alive. A symlink racing with rmdir
of its target can therefore find ->ci_dentry freed and its dirent
released, triggering WARN_ON(!atomic_read(&sd->s_count)) in configfs_get().
Take the dirent in get_target() as well, under ->d_lock and atomically
with the item reference, and pass it down to create_link(). A hashed
dentry has not been killed yet, so its ->d_fsdata reference keeps the
dirent alive there. |

net/rds: fix tcp stream corruption with large pages
rds_message_map_pages() assigns PAGE_SIZE bytes to every
scatterlist entry, even when total_len ends in a partial page. The RDS
congestion map is defined as 8192 bytes, so on systems with PAGE_SIZE
greater than 8192 the scatterlist maps bytes beyond the end of the
congestion map. RDS-TCP transmits the SG contents according to those
lengths, so the extra bytes become part of the TCP RDS stream and are
interpreted as subsequent RDS message headers, corrupting the stream.
Limit the final scatterlist mapping to the number of bytes remaining.
This has no effect on systems with a 4K page size and allows RDS-TCP to
be used on systems with 16K and larger page sizes.
The RDS selftest, which previously hung on 16K pages, now passes. |

| Zammad is a web based open source helpdesk/customer support system. Prior to 7.1.2, when a Microsoft Graph request fails, Zammad logs the error including the authentication token used to access the mailbox. The system attempts to hide this token in the log, but the masking is incomplete: for the token format Microsoft uses (JWT), only the first part is hidden, while the remaining parts remain readable in plain text. A Zammad admin with Microsoft Graph channel access can view these logs and see the partial token, which may reveal sensitive claims such as the account scope, tenant, or timing, and could assist in reconstructing the full token while it is still valid. This issue is fixed in version 7.1.2. |
| Zammad is a web based open source helpdesk/customer support system. Prior to 7.1.2, attacker-controlled HTML in inbound emails or tickets could bypass the image URL sanitizer using path traversal sequences. When an authenticated agent views the content, the browser resolves the URL to a protected API endpoint and sends the request with the agent's session cookie, enabling side effects such as forced logout without any user interaction. This issue is fixed in version 7.1.2. |
| Zammad is a web based open source helpdesk/customer support system. Prior to 7.1.2, an authenticated user with agent permissions can supply an arbitrary AI analytics run identifier to the ticket summarize endpoint and receive the AI provider error message stored for that run, even if the run belongs to a ticket the agent is not authorized to access. The disclosure is limited to the provider error string; ticket content is not exposed. This issue is fixed in version 7.1.2. |
| Zammad is a web based open source helpdesk/customer support system. In 7.0.3 and 7.1.1, under certain conditions, Zammad's verification of inbound PGP-signed email can mark a message as carrying a valid ("Good") PGP signature from a registered sender key, even though the displayed message content is not actually covered by that signature. As a result, the inbound article may be stored with a successful signature status that does not reflect the authenticity of the shown content. This can mislead agents who rely on the signature indicator when assessing the trustworthiness of incoming mail. This issue is fixed in version 7.1.2. |
| Zammad is a web based open source helpdesk/customer support system. Prior to 7.1.2, the two-factor login step let an attacker try unlimited password guesses for any account without triggering Zammad's normal lockout or rate limiting. The response also revealed whether a guess was correct, even before two-factor authentication was checked. This made it possible to brute-force weak or reused passwords. This issue is fixed in version 7.1.2. |
| Zammad is a web based open source helpdesk/customer support system. In 7.0.3 and 7.1.1, an authenticated administrator can obtain stored integration credentials in cleartext through the integration administration API. Certain responses do not consistently mask sensitive fields, so configured secrets can be returned in plain text instead of the expected masked placeholder. Both the LDAP and Exchange integrations are affected. This issue is fixed in version 7.1.2. |
| Adobe Connect is affected by an Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') vulnerability that could result in arbitrary code execution in the context of the current user. A low-privileged attacker could exploit this vulnerability to execute arbitrary SQL commands, potentially gaining elevated access or control over the victim's account or session. Exploitation of this issue does not require user interaction. Scope is changed. |
