| In the Linux kernel, the following vulnerability has been resolved:
thermal: core: Fix thermal zone governor cleanup issues
If thermal_zone_device_register_with_trips() fails after adding
a thermal governor to the thermal zone being registered, the
governor is not removed from it as appropriate which may lead to
a memory leak.
In turn, thermal_zone_device_unregister() calls thermal_set_governor()
without acquiring the thermal zone lock beforehand which may race with
a governor update via sysfs and may lead to a use-after-free in that
case.
Address these issues by adding two thermal_set_governor() calls, one to
thermal_release() to remove the governor from the given thermal zone,
and one to the thermal zone registration error path to cover failures
preceding the thermal zone device registration. |
| In the Linux kernel, the following vulnerability has been resolved:
misc: ibmasm: fix OOB MMIO read in ibmasm_handle_mouse_interrupt()
ibmasm_handle_mouse_interrupt() performs an out-of-bounds MMIO read
when the queue reader or writer index from hardware exceeds
REMOTE_QUEUE_SIZE (60).
A compromised service processor can trigger this by writing an
out-of-range value to the reader or writer MMIO register before
asserting an interrupt. Since writer is re-read from hardware on
every loop iteration, it can also be set to an out-of-range value
after the loop has already started.
The root cause is that get_queue_reader() and get_queue_writer() return
raw readl() values that are passed directly into get_queue_entry(),
which computes:
queue_begin + reader * sizeof(struct remote_input)
with no bounds check. This unchecked MMIO address is then passed to
memcpy_fromio(), reading 8 bytes from unintended device registers.
For sufficiently large values the address falls outside the PCI BAR
mapping entirely, triggering a machine check exception.
Fix by checking both indices against REMOTE_QUEUE_SIZE at the top of
the loop body, before any call to get_queue_entry(). On an out-of-range
value, reset the reader register to 0 via set_queue_reader() before
breaking, so that normal queue operation can resume if the corrupted
hardware state is transient. |
| In the Linux kernel, the following vulnerability has been resolved:
dm mirror: fix integer overflow in create_dirty_log()
The argument count calculation in create_dirty_log() performs
`*args_used = 2 + param_count` before validating against argc. When a
user provides a param_count close to UINT_MAX via the device mapper
table string, this unsigned addition wraps around to a small value,
causing the subsequent `argc < *args_used` check to be bypassed.
The overflowed param_count is then passed as argc to dm_dirty_log_create(),
where it can cause out-of-bounds reads on the argv array.
Fix by comparing param_count against argc - 2 before performing the
addition, following the same pattern used by parse_features() in the
same file. Since argc >= 2 is already guaranteed, the subtraction is
safe. |
| In the Linux kernel, the following vulnerability has been resolved:
libceph: Prevent potential null-ptr-deref in ceph_handle_auth_reply()
If a message of type CEPH_MSG_AUTH_REPLY contains a zero value for both
protocol and result, this is currently not treated as an error. In case
of ac->negotiating == true and ac->protocol > 0, this leads to setting
ac->protocol = 0 and ac->ops = NULL. Thereafter, the check for
ac->protocol != protocol returns false, and init_protocol() is not
called. Subsequently, ac->ops->handle_reply() is called, which leads to
a null pointer dereference, because ac->ops is still NULL.
This patch changes the check for ac->protocol != protocol to
!ac->protocol, as this also includes the case when the protocol was set
to zero in the message. This causes the message to be treated as
containing a bad auth protocol. |

mm/damon/core: fix damon_call() vs kdamond_fn() exit race
Patch series "mm/damon/core: fix damon_call()/damos_walk() vs kdmond exit
race".
damon_call() and damos_walk() can leak memory and/or deadlock when they
race with kdamond terminations. Fix those.
This patch (of 2);
When kdamond_fn() main loop is finished, the function cancels all
remaining damon_call() requests and unset the damon_ctx->kdamond so that
API callers and API functions themselves can know the context is
terminated. damon_call() adds the caller's request to the queue first.
After that, it shows if the kdamond of the damon_ctx is still running
(damon_ctx->kdamond is set). Only if the kdamond is running, damon_call()
starts waiting for the kdamond's handling of the newly added request.
The damon_call() requests registration and damon_ctx->kdamond unset are
protected by different mutexes, though. Hence, damon_call() could race
with damon_ctx->kdamond unset, and result in deadlocks.
For example, let's suppose kdamond successfully finished the damon_call()
requests cancelling. Right after that, damon_call() is called for the
context. It registers the new request, and shows the context is still
running, because damon_ctx->kdamond unset is not yet done. Hence the
damon_call() caller starts waiting for the handling of the request.
However, the kdamond is already on the termination steps, so it never
handles the new request. As a result, the damon_call() caller threads
infinitely waits.
Fix this by introducing another damon_ctx field, namely
call_controls_obsolete. It is protected by the
damon_ctx->call_controls_lock, which protects damon_call() requests
registration. Initialize (unset) it in kdamond_fn() before letting
damon_start() returns and set it just before the cancelling of remaining
damon_call() requests is executed. damon_call() reads the obsolete field
under the lock and avoids adding a new request.
After this change, only requests that are guaranteed to be handled or
cancelled are registered. Hence the after-registration DAMON context
termination check is no longer needed. Remove it together.
Note that the deadlock will not happen when damon_call() is called for
repeat mode request. In tis case, damon_call() returns instead of waiting
for the handling when the request registration succeeds and it shows the
kdamond is running. However, if the request also has dealloc_on_cancel,
the request memory would be leaked.
The issue is found by sashiko [1]. |
| In the Linux kernel, the following vulnerability has been resolved:
net: qrtr: ns: Limit the maximum number of lookups
Current code does no bound checking on the number of lookups a client can
perform. Though the code restricts the lookups to local clients, there is
still a possibility of a malicious local client sending a flood of
NEW_LOOKUP messages over the same socket.
Fix this issue by limiting the maximum number of lookups to 64 globally.
Since the nameserver allows only atmost one local observer, this global
lookup count will ensure that the lookups stay within the limit.
Note that, limit of 64 is chosen based on the current platform
requirements. If requirement changes in the future, this limit can be
increased. |

net/smc: avoid early lgr access in smc_clc_wait_msg
A CLC decline can be received while the handshake is still in an early
stage, before the connection has been associated with a link group.
The decline handling in smc_clc_wait_msg() updates link-group level sync
state for first-contact declines, but that state only exists after link
group setup has completed. Guard the link-group update accordingly and
keep the per-socket peer diagnosis handling unchanged.
This preserves the existing sync_err handling for established link-group
contexts and avoids touching link-group state before it is available. |
| In the Linux kernel, the following vulnerability has been resolved:
crypto: algif_aead - snapshot IV for async AEAD requests
AF_ALG AEAD AIO requests currently use the socket-wide IV buffer during
request processing. For async requests, later socket activity can
update that shared state before the original request has fully
completed, which can lead to inconsistent IV handling.
Snapshot the IV into per-request storage when preparing the AEAD
request, so in-flight operations no longer depend on mutable socket
state. |

mm/slab: return NULL early from kmalloc_nolock() in NMI on UP
On UP kernels (!CONFIG_SMP), spin_trylock() is a no-op that
unconditionally succeeds even when the lock is already held. As a
result, kmalloc_nolock() called from NMI context can re-enter the slab
allocator and acquire n->list_lock that the interrupted context is
already holding, corrupting slab state.
With CONFIG_DEBUG_SPINLOCK on UP, the following BUG is triggered with
the slub_kunit test module:
BUG: spinlock trylock failure on UP on CPU#0, kunit_try_catch/243

| In the Linux kernel, the following vulnerability has been resolved:
tcp: fix a signed-integer-overflow bug in tcp_add_backlog()
The type of sk_rcvbuf and sk_sndbuf in struct sock is int, and
in tcp_add_backlog(), the variable limit is caculated by adding
sk_rcvbuf, sk_sndbuf and 64 * 1024, it may exceed the max value
of int and overflow. This patch reduces the limit budget by
halving the sndbuf to solve this issue since ACK packets are much
smaller than the payload. |
| Incorrect access control in statping-ng v0.93.0 allows attackers to escalate privileges to Administrator and access sensitive components. |
| DbGate is cross-platform database manager. In versions 7.1.8 and prior, the POST /runners/load-reader endpoint in DbGate accepts a functionName parameter that is directly interpolated into a JavaScript code template without any sanitization or validation. An authenticated user (with basic access, no special permissions required) can inject arbitrary JavaScript code that executes on the server with full process privileges, bypassing the require=null sandbox restriction. An authenticated user with basic access (no admin role, no run-shell-script permission required) can: execute arbitrary OS commands on the DbGate server with the privileges of the Node.js process, read/write any file accessible to the process, pivot to connected databases by reading connection credentials from DbGate's storage, and compromise the host system - in Docker deployments, this typically means root access within the container. |
| Bernd Bestel grocy v4.6.0 was discovered to contain a SQL injection vulnerability in the product-group parameter at /stockreports/spendings. This vulnerability allows attackers to access sensitive database information via a crafted SQL statement. |
| Cursor is a code editor built for programming with AI. In versions prior to 3.0.0, the Cursor Desktop could execute workspace-defined Claude hook commands from .claude/settings.local.json without dedicated user approval. A malicious workspace or agent-created file could configure hooks that run local commands in the user's context when an agent turn ends. This could allow sandbox escape, persistence across turns, local data access, or follow-on compromise. This issue has been fixed in version 3.0.0. |

ext4_fill_super
ext4_orphan_cleanup
--- loop1: assume last_orphan is 12 ---
list_add(&EXT4_I(inode)->i_orphan, &EXT4_SB(sb)->s_orphan)
ext4_truncate --> return 0
ext4_inode_attach_jinode --> return -ENOMEM
iput(inode) --> free inode<12>
--- loop2: last_orphan is still 12 ---
list_add(&EXT4_I(inode)->i_orphan, &EXT4_SB(sb)->s_orphan);
// use inode<12> and trigger UAF
To solve this issue, we need to propagate the return value of
ext4_inode_attach_jinode() appropriately. |

Bluetooth: hci_sync: Fix UAF in hci_disconnect_all_sync
Use-after-free can occur in hci_disconnect_all_sync if a connection is
deleted by concurrent processing of a controller event.
To prevent this the code now tries to iterate over the list backwards
to ensure the links are cleanup before its parents, also it no longer
relies on a cursor, instead it always uses the last element since
hci_abort_conn_sync is guaranteed to call hci_conn_del.
