| In the Linux kernel, the following vulnerability has been resolved:
ieee802154: Avoid calling WARN_ON() on -ENOMEM in cfg802154_switch_netns()
It's pointless to call WARN_ON() in case of an allocation failure in
dev_change_net_namespace() and device_rename(), since it only leads to
useless splats caused by deliberate fault injections, so avoid it.
Found by Linux Verification Center (linuxtesting.org) with Syzkaller. |
| In the Linux kernel, the following vulnerability has been resolved:
Revert "PCI/MSI: Unmap MSI-X region on error"
This reverts commit 1a8d4c6ecb4c81261bcdf13556abd4a958eca202.
Commit 1a8d4c6ecb4c ("PCI/MSI: Unmap MSI-X region on error") added an
iounmap(dev->msix_base) on the error path of msix_capability_init() to
release the MSI-X region when msix_setup_interrupts() fails.
When msix_setup_interrupts() fails, the call chain is:
msix_setup_interrupts()
-> __msix_setup_interrupts()
struct pci_dev *dev __free(free_msi_irqs) = __dev;
...
return ret; // __free cleanup fires on error
The __free(free_msi_irqs) cleanup calls pci_free_msi_irqs(), which
already handles the unmap:
void pci_free_msi_irqs(struct pci_dev *dev)
{
pci_msi_teardown_msi_irqs(dev);
if (dev->msix_base) {
iounmap(dev->msix_base); // already unmapped here
dev->msix_base = NULL; // and set to NULL
}
}
So dev->msix_base is unmapped and set to NULL before
msix_setup_interrupts() returns to msix_capability_init(). The
"goto out_unmap" introduced by commit 1a8d4c6ecb4c ("PCI/MSI: Unmap
MSI-X region on error") then calls iounmap() a second time on a NULL
pointer.
This was reproduced on Intel Emerald Rapids (192 CPUs) while
running tools/testing/selftests/kexec/test_kexec_jump.sh:
WARNING: CPU#44 at iounmap+0x2a/0xe0

RDI=0 confirms iounmap() is called with NULL.
Restore the original "goto out_disable" and leave the unmap to the
existing __free(free_msi_irqs) cleanup. |

riscv: drop __init from vec_check_unaligned_access_speed_all_cpus
This function runs within a kthread and need not necessarily finish
before system finishes boot and free_initmem() unmaps the .init.text
section. This function makes calls to SBI for probing unaligned access
speed, and if this is slow for some reason (say some debug prints were
added to SBI), the kthread can still be running at this point and result
in an instruction page fault when trying to fetch from the freed region.

| In the Linux kernel, the following vulnerability has been resolved:
KVM: arm64: vgic: Avoid double-deactivate of IRQs in the nested context
In the nested state, the physical interrupt has already been
deactivated through the HW bit in the LR. The extra deactivation
would be harmless but can hit an errata case on AmpereOne, so
avoid it here.
On AmpereOne, deactivating a physical interrupt through
ICC_DIR_EL1 or ICC_EOIR1_EL1 (depending on EOImode) which is not
active, but is the highest priority pending interrupt causes the
cpu to lose the interrupt pending state and also prevents the
delivery of future interrupts. |
| In the Linux kernel, the following vulnerability has been resolved:
drm/amdkfd: Fix missing authorization check in KFD_IOC_DBG_TRAP_DISABLE
Prevent unauthorized termination of active GPU debug sessions.
Previously, users with /dev/kfd access could terminate another process's
debug session without proper ownership or ptrace authorization.

| The Everest Forms plugin for WordPress is vulnerable to Server-Side Request Forgery in all versions up to, and including, 3.4.4. This is due to the `load_previous_field_value()` method in `class-evf-form-task.php` accepting arbitrary URL values from `$_POST` data for upload fields without domain restriction, which are then passed to `wp_remote_head()` in the `get_local_file_size()` method of `class-evf-form-fields-upload.php`. This makes it possible for unauthenticated attackers to force the WordPress server to make outbound HTTP HEAD requests to arbitrary URLs by submitting a form with an upload field containing a malicious URL while leaving a required field empty to trigger form re-rendering. |
| Uncontrolled Recursion vulnerability in the Elixir standard library allows an attacker who controls a list passed to inspect/1, List.to_string/1, or List.to_charlist/1 to exhaust a BEAM node's memory.
Inspect.List's charlist branch in lib/elixir/lib/inspect.ex classifies a list as a charlist using List.ascii_printable?/2, which examines only the first :printable_limit (4096 by default) elements, and then calls IO.chardata_to_string/1 on the whole term. A list whose printable prefix exceeds that limit but which contains a later element that is not a code point (an atom, an out-of-range integer, or an improper tail) is therefore mis-classified, and the conversion raises ArgumentError. That conversion runs inside List.to_string/1, whose rescue clause builds its message by interpolating inspect(list), which re-enters the same branch and raises again. The nested inspection is an argument to raise, so the recursion is not in tail position and every level is retained: the process stack grows monotonically while each cycle re-walks the list, until the process is killed by max_heap_size or, by default, the node runs out of memory. List.to_charlist/1 has the same rescue shape.
Below the printable limit the inner inspect/1 sees the invalid element within its counter and renders the list in ordinary bracket form, so a single ArgumentError is raised and no recursion occurs.
This issue affects elixir: from 1.15.0-rc.0 before 1.18.5, from 1.19.0-rc.0 before 1.19.6, and from 1.20.0-rc.0 before 1.20.4. |
| In the Linux kernel, the following vulnerability has been resolved:
powerpc/perf: fix preempt count underflow in fsl_emb_pmu_del
fsl_emb_pmu_del() unconditionally calls put_cpu_var(cpu_hw_events) at
the 'out:' label, but only calls the matching get_cpu_var() after the
'i < 0' early-return check. When event->hw.idx is negative the
function jumps to 'out:' without having taken get_cpu_var(), and the
trailing put_cpu_var() then issues an unmatched preempt_enable(),
underflowing preempt_count.
On a CONFIG_PREEMPT=y kernel preempt_count would underflow and
eventually present as a 'scheduling while atomic' BUG.
Move put_cpu_var() to pair with get_cpu_var() so the percpu access is
correctly bracketed and the 'out:' label only handles perf_pmu_enable. |
| In the Linux kernel, the following vulnerability has been resolved:
crypto: ccp/sev-dev-tsm - bail out early when pdev->bus is NULL
dsm_create() initially checks pdev->bus when computing segment_id:
u8 segment_id = pdev->bus ? pci_domain_nr(pdev->bus) : 0;
But the next two lines unconditionally dereference pdev->bus via
pcie_find_root_port() and especially pci_dev_id(pdev), which expands
to PCI_DEVID(dev->bus->number, dev->devfn). If pdev->bus is in fact
NULL, segment_id is initialised to 0 but the very next statement
crashes the kernel.
smatch flags this:
drivers/crypto/ccp/sev-dev-tsm.c:253 dsm_create() error: we
previously assumed 'pdev->bus' could be null (see line 251)
Make the NULL handling consistent: if pdev->bus is NULL the device
has no PCI context to work with and SEV TIO setup cannot proceed,
so return -ENODEV before any of the bus-dependent lookups. The
remaining initialisation now runs only on the path where pdev->bus
is known to be valid.
No change for callers where pdev->bus is non-NULL, which is the
only case where dsm_create() did meaningful work before this change. |
| In the Linux kernel, the following vulnerability has been resolved:
hwmon: (occ) unregister sysfs devices outside occ lock
occ_active(false) and occ_shutdown() unregister sysfs-backed devices while
occ->lock is held. hwmon_device_unregister() and sysfs_remove_group() can
wait for active sysfs callbacks to drain, and those callbacks can enter the
OCC update path and try to take occ->lock again. That gives the unregister
paths the lock ordering occ->lock -> sysfs callback drain, while a callback
has the opposite edge sysfs callback -> occ->lock.
This issue was found by our static analysis tool and then manually
reviewed against the current tree.
The grounded PoC kept the real unregister and callback carrier:
occ_shutdown()
hwmon_device_unregister()
occ_show_temp_1()
occ_update_response()
Lockdep reported the circular dependency with occ_shutdown() already
holding the OCC mutex and hwmon_device_unregister() waiting on the sysfs
side:

*** DEADLOCK ***
Serialize hwmon registration and removal with a separate hwmon_lock.
Under that lock, detach occ->hwmon and update occ->active while occ->lock
is held so concurrent OCC state changes still see a stable state, then
drop occ->lock before calling hwmon_device_unregister(). Remove the
driver sysfs group before taking occ->lock in occ_shutdown(), so draining
the driver attributes cannot wait while the OCC mutex is held. Also make
OCC update callbacks return -ENODEV after deactivation, so callbacks that
already passed sysfs active protection do not poll the hardware after
teardown has detached the hwmon device. |
| An issue in the inviteController.js component in Bluewave Labs Checkmate <=3.3.0 allows remote authenticated administrators to escalate privileges to superadmin via the role parameter to the /api/v1/invite endpoint. |
| gitoxide versions from 0.25.4 contain an HTTP credential leak vulnerability in the curl-based transport backend where credentials are sent to attacker-controlled servers after HTTP redirects. The vulnerability occurs because credential validation checks the original URL instead of the effective URL after redirect, allowing attackers to steal authentication tokens through cross-domain redirects or HTTPS-to-HTTP downgrades. |
| gitoxide gix-packetline versions before 0.21.5 contain a panic vulnerability in the TextRef implementation that occurs when processing side-band packet lines with empty payloads. A malicious Git server can send a crafted side-band packet to trigger an index out of bounds panic, aborting the client process during fetch operations without authentication. |
| filebrowser through 2.63.23 fails to validate named pipes in directory archive and public download handlers, allowing attackers to trigger blocking open syscalls. Authenticated users or anonymous visitors with public share links can repeatedly request archives containing named pipes to pin server goroutines and exhaust connection resources. |
| SiYuan versions before v3.8.1 contain a server-side request forgery vulnerability in the http_request and web_fetch agent tools that perform DNS resolution only at guard time without validating the connect-time resolution. Attackers can use DNS rebinding to answer the guard resolution with a public IP and the connect resolution with a private or metadata IP, bypassing the SSRF defense to access cloud instance metadata and internal services. |
| In the Linux kernel, the following vulnerability has been resolved:
bpf: Disable xfrm_decode_session hook attachment
BPF LSM programs can currently attach to xfrm_decode_session(). That
hook may return an error, but security_skb_classify_flow() calls it
from a void path and triggers BUG_ON() if an error is returned.
Disable BPF attachment to the hook to prevent a BPF LSM program from
turning packet classification into a full panic. |
| In the Linux kernel, the following vulnerability has been resolved:
drm/vmwgfx: enforce cursor size limits for MOB cursors
vmw_cursor_plane_atomic_check() bounds cursor width and height only
on the legacy update path; the SVGA_CAP2_CURSOR_MOB path -- the
default on modern hosts -- accepts any size. When the requested size
exceeds SVGA_REG_CURSOR_MAX_DIMENSION or SVGA_REG_MOB_MAX_SIZE,
vmw_cursor_mob_get() returns -EINVAL and leaves vps->cursor.mob NULL.
Its return value is then discarded in vmw_cursor_plane_prepare_fb(),
so the subsequent vmw_cursor_update_mob() calls
vmw_bo_map_and_cache(NULL) and oopses inside
vmw_bo_map_and_cache_size() on the tbo.base.size load.
Reachable from any DRM master via DRM_IOCTL_MODE_CURSOR2 with a
sufficiently large width or height (e.g. cursor_max_dim + 1).
Reject oversized cursors in atomic_check for both MOB-backed cursor
update types. The MOB byte-size limit only applies to the
SVGA_CAP2_CURSOR_MOB path (vmw_cursor_mob_size() returns 0 for
GB_ONLY); compute the required MOB size in 64-bit to avoid overflow
when very large dimensions are requested.
In prepare_fb only call vmw_cursor_mob_get()/_map() for
VMW_CURSOR_UPDATE_MOB -- the GB_ONLY path uses bo->map.virtual
directly and would otherwise be silently downgraded to NONE on hosts
without SVGA_CAP2_CURSOR_MOB (where vmw_cursor_mob_get() always
returns -EINVAL). Degrade the update to NONE if vmw_cursor_mob_get()
or vmw_cursor_mob_map() fails so the update path does not run with a
NULL backing MOB. |
| A missing input-validation issue in MongoDB libmongocrypt's automatic-encryption context setup allows a caller-supplied database identifier to be accepted without sanitization. The resulting impact is limited to incorrect schema selection, which may lead to limited disclosure or modification of information handled by the application. |
| The wpForo Forum plugin for WordPress is vulnerable to SQL Injection via the 'referer' parameter in all versions up to, and including, 2.4.17. This is due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for unauthenticated attackers to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database. |

mm: migrate_device: fix pte_pfn/pte_dirty called on non-present PTE
pte_pfn() and pte_dirty() have undefined behaviour when called on a
non-present PTE. In migrate_vma_collect_pmd(), these functions may be
invoked on non-present entries (e.g., device-private entries), leading
to potential crashes from pte_pfn() or incorrect dirty folio accounting
from pte_dirty(). Fix both by guarding with pte_present() checks. |
