| In the Linux kernel, the following vulnerability has been resolved:
nvme-pci: fix out-of-bounds access in nvme_setup_descriptor_pools
nvme_setup_descriptor_pools() indexes dev->descriptor_pools[] using the
numa_node forwarded from hctx->numa_node by its single caller,
nvme_init_hctx_common(). On a non-NUMA kernel hctx->numa_node is
NUMA_NO_NODE (-1). Because the parameter was declared 'unsigned', the
value becomes UINT_MAX and the index walks off the array (sized to
nr_node_ids), faulting during nvme_alloc_ns() and leaving the namespace
without a /dev node.
Reproduces on any NVMe controller probed by a CONFIG_NUMA=n kernel:
BUG: unable to handle page fault for address: ffff889101603d38
RIP: 0010:nvme_init_hctx_common+0x5a/0x190 [nvme]
Call Trace:
nvme_init_hctx+0x10/0x20 [nvme]

nvme_scan_ns_async+0x23/0x30 [nvme_core]
Switch the parameter to int and fall back to node 0 when it is
NUMA_NO_NODE; node 0 is always present. |
| In the Linux kernel, the following vulnerability has been resolved:
nvmet-tcp: fix page fragment cache leak in error path
In nvmet_tcp_alloc_queue(), when a connection is closed during the
allocation process (e.g., nvmet_tcp_set_queue_sock() returns -ENOTCONN),
the error handling jumps to out_destroy_sq and then to out_ida_remove
without draining the page fragment cache.
Although nvmet_tcp_free_cmd() is called in some error paths to release
individual page fragments, the underlying page cache reference held by
queue->pf_cache is never released. The first allocation using pf_cache
is the call to nvmet_tcp_alloc_cmd() for queue->connect, which happens
after ida_alloc() returns successfully. This results in a page leak each
time a connection fails during allocation, which could lead to memory
exhaustion over time if connections are repeatedly opened and closed.
Fix this by calling page_frag_cache_drain() before freeing the queue
structure in the out_ida_remove label. |
| In the Linux kernel, the following vulnerability has been resolved:
RDMA/irdma: Fix out-of-bounds write in irdma_copy_user_pgaddrs
The irdma_copy_user_pgaddrs function loops through all of the umem DMA
blocks to populate the PBLEs and will stop when either the last DMA
block is reached or palloc->total_cnt is reached. The issue is that
the logic for checking palloc->total_cnt would only work for non-zero
values.
When irdma_setup_pbles is called with lvl==0, it
calls irdma_copy_user_pgaddrs with palloc->total_cnt==0, which means
the only way to break out of the loop is to reach the last umem DMA
block, which means it could end up going beyond the fixed size of 4
iwmr->pgaddrmem array that is used in the lvl==0 case.
In the case of QP/CQ/SRQ rings, the value of lvl is determined by a
separate input (for example, req.cq_pages in the case of a CQ). So,
we must perform explicit checking to ensure we don't overflow the
pgaddrmem array if the user provides a umem that consists of more
blocks than their provided req.cq_pages. |
| In the Linux kernel, the following vulnerability has been resolved:
tracing: Bound synthetic-field strings with seq_buf
The synthetic field helpers build a prefixed synthetic variable name and
a generated hist command in fixed MAX_FILTER_STR_VAL buffers. The
current code appends those strings with raw strcat(), so long key lists,
field names, or saved filters can run past the end of the staging
buffers.
Build both strings with seq_buf and propagate -E2BIG if either the
synthetic variable name or the generated command exceeds
MAX_FILTER_STR_VAL. This keeps the existing tracing-side limit while
using the helper intended for bounded command construction.

| In the Linux kernel, the following vulnerability has been resolved:
liveupdate: fix u-a-f in luo_file_unpreserve_files() and luo_file_finish()
In luo_file_unpreserve_files() and luo_file_finish(), reorder
module_put() and xa_erase() to ensure the file handler module remains
pinned while its operations are being accessed.
Specifically, luo_get_id() dereferences fh->ops->get_id, so the module
reference must be held until after xa_erase() (which calls luo_get_id)
completes.
For luo_file_finish(), this requires moving the module_put() call out of
the luo_file_finish_one() helper and into the main loop of
luo_file_finish() itself. |
| In the Linux kernel, the following vulnerability has been resolved:
dm: limit target bio polling to one shot
dm_poll_bio() is the ->poll_bio() callback for a stacked dm device.
The caller only knows about the dm queue, so it may decide to do a
spinning poll if it thinks a single queue is being polled. Passing those
flags unchanged to the mapped clone lets blk_mq_poll() spin on a target
queue from inside dm_poll_bio().
With io_uring IOPOLL on a dm-stripe target this can keep a task in
dm_poll_bio() -> bio_poll() -> blk_mq_poll()
long enough to trigger an RCU CPU stall, before io_uring gets back to
io_iopoll_check() and its need_resched() check.
Keep dm's ->poll_bio() bounded by forcing one-shot polling for target
bios. The caller can invoke dm_poll_bio() again if it wants to keep
polling, and it also gets a chance to reap completions or reschedule
between passes. |
| In the Linux kernel, the following vulnerability has been resolved:
drm/syncobj: Fix memory leak in drm_syncobj_find_fence()
Commit 18226ba52159 ("drm/syncobj: reject invalid flags in
drm_syncobj_find_fence") forgot to take into account the fact that
drm_syncobj_find() takes a reference to syncobj and returns early
without dropping the reference, leading to memory leaks.

| In the Linux kernel, the following vulnerability has been resolved:
RDMA/srpt: fix integer overflow in immediate data length check
imm_buf->len is a user-controlled uint32_t received from the network.
Adding it to imm_data_offset without overflow checking allows a
malicious initiator to send len=0xFFFFFFFF, causing req_size to wrap
around to a small value, bypassing the bounds check, and subsequently
passing a ~4GB length to sg_init_one().
Use check_add_overflow() to detect wrapping before the comparison. |
| In the Linux kernel, the following vulnerability has been resolved:
wifi: rtw88: fix wrong pci_get_drvdata type in AER handlers
rtw88 stores an ieee80211_hw pointer via pci_set_drvdata() at probe
time, but io_error_detected() and io_resume() retrieve it as a
net_device pointer. This causes netif_device_detach/attach to
operate on an ieee80211_hw struct, reading and writing at wrong
offsets.
Use ieee80211_stop_queues/wake_queues instead, consistent with
every other queue stop/start path in the driver. |
| In the Linux kernel, the following vulnerability has been resolved:
accel/amdxdna: Adjust size for copy_to_user()
The amount of data returned to user space should be limited by the buffer
size provided by the application. If the buffer is smaller than the data
size, return only the portion that fits instead of failing. |
| In the Linux kernel, the following vulnerability has been resolved:
accel/amdxdna: Fix leak when pinning ubuf pages
When pin_user_pages_fast() returns fewer pages than requested, the pages
that were successfully pinned are not released, leading to a leak.
Fix this by unpinning any partially pinned pages before returning failure. |
| Tie::Hash::Regex versions before 2.0.0 for Perl will throw an exception on unparseable lookup keys.
The FETCH, EXISTS and DELETE methods throw an exception when on malformed regular expressions.
Each method falls back to a regex match when the key is not already stored in the hash, compiling the caller's key with a bare qr// and no eval guard. A key that is not a valid regular expression pattern, such as a single unmatched bracket, dies.
An application that looks up externally supplied strings in a tied hash will die on an invalid key. |
| In the Linux kernel, the following vulnerability has been resolved:
dlm: fix add msg handle in send_queue ordered
In a benchmark scenario triggering a lot of requests that triggers a lot
of DLM messages on the network it can be that the mh->seq is not ordered
according the oldest seq number. This ordering is required by
dlm_receive_ack as "before(mh->seq, seq)" will stop to check for older
sequence numbers that are ordered in the tail of "node->send_queue".
The side effects of not having it correct ordered regarding
"before(mh->seq, seq)" are refcounting issues and use-after free.
I only was able to reproduce this issue in a experimental DLM branch
and a user space DLM benchmark that uses io_uring. After changing this I
don't experienced any refcounting with the sending buffer issues anymore. |
| In the Linux kernel, the following vulnerability has been resolved:
OPP: Fix race between OPP addition and lookup
A race exists between dev_pm_opp_add_dynamic() and
dev_pm_opp_find_freq_exact():
CPU0 (add) CPU1 (lookup)
------------------------------- ------------------------------
_opp_add()
mutex_lock()
list_add(&new_opp->node, head)
mutex_unlock() _opp_table_find_key()
mutex_lock()
dev_pm_opp_get(opp)
kref_get()
mutex_unlock()
kref_init(&new_opp->kref)
dev_pm_opp_put()
kref_put_mutex()
The newly added OPP is inserted into the list before its kref is
initialized. A concurrent lookup can find this OPP and increment its
reference count while it is still uninitialized, leading to refcount
corruption and a potential premature free.
Fix this by initializing ->kref and ->opp_table before making the OPP
visible via list_add(). This ensures any concurrent lookup observes a
fully initialized object.

| In the Linux kernel, the following vulnerability has been resolved:
wifi: rtw89: add bounds check on firmware mac_id in link lookup
The mac_id field in RX descriptors is 8 bits wide (0-255), but
assoc_link_on_macid[] has only RTW89_MAX_MAC_ID_NUM (128) entries.
While the driver currently assigns mac_id values below 128, the
descriptor value comes from firmware and is not validated before use
as an array index. Add a defensive bounds check in
rtw89_assoc_link_rcu_dereference() to guard against out-of-range
firmware values. |
| In the Linux kernel, the following vulnerability has been resolved:
wifi: rtw88: fix OOB read from firmware RX descriptor exceeding DMA buffer
In rtw_pci_rx_napi(), new_len is computed as the sum of pkt_len (14-bit
descriptor field, max 16383) and pkt_offset (drv_info_sz + shift, both
firmware-controlled). The result can exceed RTK_PCI_RX_BUF_SIZE (11478),
causing an out-of-bounds read from the pre-allocated DMA buffer when
skb_put_data copies new_len bytes. The USB transport already validates
this (rtw_usb_rx_data_put checks against RTW_USB_MAX_RECVBUF_SZ); the
PCIe path does not.
Add a check that new_len does not exceed the DMA buffer size. |
