CVSS v3.1 |
| In the Linux kernel, the following vulnerability has been resolved:
wifi: mt76: mt7996: clear stale link state on full reset
After a full chip reset, mac80211 reconfig replays interface, link and
channel context setup. mt7996_vif_link_add() short-circuits when the
link_id is still marked in mvif->valid_links, a state introduced for
postponing link teardown to interface removal. The reset path frees the
link structures without clearing those bits, so the replayed setup never
re-creates dev_info/bss_info/STA records in the restarted firmware and
never re-registers the link wcid, leaving the device inoperative.
The reset path also leaks every allocated MLD index: per-link indices
and the per-vif group/remap indices are re-allocated from scratch during
reconfig, but the old bits stay set in the masks, so repeated full
resets exhaust the index space.
Clear valid_links in the reset vif iterator and reset the MLD index
masks alongside the existing omac_mask clearing. |
| In the Linux kernel, the following vulnerability has been resolved:
fuse: Fix the condition to enable over-io-uring
The existing condition in fuse_uring_cmd() is there only to avoid
disabling io-uring for connections that already run with it, missing
was a condition to refuse any IORING_OP_URING_CMD if the
connection/channel didn't get enabled because of missing FUSE_INIT
reply flag FUSE_OVER_IO_URING. Without the reply flag the barrier in
fuse_uring_ready() doesn't work and IO could already be going on and
cause deadlock states (at a minimum one between fch->bg_lock and
queue->lock).
The change itself is trivial, but brings behavior change,
FUSE_OVER_IO_URING has to be set in the FUSE_INIT_REPLY by fuse servers
to accept any IORING_OP_URING_CMD. Libfuse does that and the only
non-libfuse implementation I found (fractal-fuse) also does it.
Qemu patches for fuse-io-uring are not merged yet, as far as I know.
Moved up is the smp_load_acquire(&fch->initialized) check, as a
fuse-server implementation might try to setup io-uring before FUSE_INIT
is processed and might have gotten -EOPNOTSUPP instead of -EAGAIN.
Also fixed is a stale comment that explains the handling of the
FUSE_OVER_IO_URING flag in early RFC versions.
If there should be a report from any library or application we
probably need to revert this commit. |
| In the Linux kernel, the following vulnerability has been resolved:
media: chips-media: wave5: Resume device before setting EOS flag
Setting the EOS flag talks to the firmware via send_firmware_command(),
which accesses VPU registers. Both the STREAMOFF path
(wave5_vpu_dec_job_abort()) and the V4L2_DEC_CMD_STOP path
(wave5_vpu_dec_stop()) can run while the device is runtime suspended, so
those register accesses hit powered-down hardware and the SoC raises an
asynchronous SError, panicking the kernel:
SError Interrupt on CPU3, code 0x00000000bf000000 -- SError
send_firmware_command+0x2c/0x160 [wave5]
wave5_vpu_dec_set_bitstream_flag+0x6c/0x80 [wave5]
wave5_vpu_dec_update_bitstream_buffer+0x80/0xec [wave5]
wave5_vpu_dec_job_abort+0x44/0xa0 [wave5]

v4l2_m2m_streamoff+0x24/0x140 [v4l2_mem2mem]
Resume the device with pm_runtime_resume_and_get() around the EOS
firmware command and release it with pm_runtime_put_autosuspend(),
matching the runtime PM handling already done in
wave5_vpu_dec_device_run(). |
| In the Linux kernel, the following vulnerability has been resolved:
wifi: cfg80211: undo netns switch if renaming the wiphy fails
Once all the interfaces have been moved, cfg80211_switch_netns()
moves the wiphy itself by setting its network namespace and then
renaming it, which makes sysfs move it. The rename can fail (but
only on allocation failures), leaving things mixed up and hitting
the warning there.
Ignoring it isn't great, undo the move and let the change fail
in this case. If undo fails then WARN, then things would again
be stuck in two different network namespaces. |
| Unspecified vulnerability in Oracle Java SE 6u101, 7u85, and 8u60, and Java SE Embedded 8u51, allows remote attackers to affect confidentiality, integrity, and availability via unknown vectors related to Serialization. |
| drivers/scsi/stex.c in the Linux kernel through 5.19.9 allows local users to obtain sensitive information from kernel memory because stex_queuecommand_lck lacks a memset for the PASSTHRU_CMD case. |
| A defect in the Qt for MCUs core string handling causes heap memory corruption. When an application passes text into Qt Quick Ultralite using the public Qul::String interface type, and that text is held in a std::string, the conversion to the internal string type copies the pointer without taking ownership of it. Two objects then release the same memory, producing a double free, an invalid free, or a use-after-free. |
| SQLite through 3.31.1 allows attackers to cause a denial of service (segmentation fault) via a malformed window-function query because the AggInfo object's initialization is mishandled. |
| On the x86-64 architecture, the GNU C Library (aka glibc) before 2.31 fails to ignore the LD_PREFER_MAP_32BIT_EXEC environment variable during program execution after a security transition, allowing local attackers to restrict the possible mapping addresses for loaded libraries and thus bypass ASLR for a setuid program. |
| In the Linux kernel, the following vulnerability has been resolved:
mm/huge_memory: initialise workingset state before folio split
xas_try_split() adds __GFP_ACCOUNT for page-cache xa_nodes, but
__folio_split() leaves the xa_state's xa_lru unset. That lets a live,
memcg-charged xa_node exist without being linked into the mapping's
shadow_nodes list_lru; when reclaim later walks the list_lru it trips
VM_WARN_ON(!css_is_dying()).
Use mapping_set_update() to install both the workingset update callback
and the shadow_nodes list_lru on the xa_state. |
| fs/nfs/nfs4client.c in the Linux kernel before 5.13.4 has incorrect connection-setup ordering, which allows operators of remote NFSv4 servers to cause a denial of service (hanging of mounts) by arranging for those servers to be unreachable during trunking detection. |
| net/can/bcm.c in the Linux kernel through 5.12.10 allows local users to obtain sensitive information from kernel stack memory because parts of a data structure are uninitialized. |
| Improper initialization in the firmware for some Intel(R) Processors may allow a privileged user to potentially enable escalation of privilege via local access. |
| Insufficient initialization in Intel(R) SGX SDK Windows versions 2.4.100.51291 and earlier, and Linux versions 2.6.100.51363 and earlier, may allow an authenticated user to enable information disclosure, escalation of privilege or denial of service via local access. |
| Python's elementtree C accelerator failed to initialise Expat's hash salt during initialization. This could make it easy to conduct denial of service attacks against Expat by constructing an XML document that would cause pathological hash collisions in Expat's internal data structures, consuming large amounts CPU and RAM. The vulnerability exists in Python versions 3.7.0, 3.6.0 through 3.6.6, 3.5.0 through 3.5.6, 3.4.0 through 3.4.9, 2.7.0 through 2.7.15. |
| MISP contains a defect in its event save workflow that prevents the correlation engine from recalculating correlations when an event's distribution level or sharing group is modified.
When a user edits an existing event and changes its distribution or sharing_group_id, the internal before-save hook stored the incoming (new) data rather than the previously persisted values. As a result, the after-save comparison that determines whether a correlation refresh is needed never detected the change, and stale correlations persisted.
Security impact:
- Stale correlations may continue to expose event data to users in a broader sharing group after the event has been moved to a more restrictive group, resulting in unintended information disclosure.
- Conversely, newly relevant correlations may not appear after a distribution widening, degrading the completeness of threat intelligence sharing.
Preconditions:
- An authenticated user with write access to at least one MISP event.
- The user modifies the event's distribution or sharing_group_id field.

| In the Linux kernel, the following vulnerability has been resolved:
net: psp: avoid conflicts with skb->decrypted and sk_validate_xmit_skb()
PSP conflicts with TLS ULP in its usage of both skb->decrypted and
sk->sk_validate_xmit_skb().
Make PSP mutually exclusive with TLS ULP, the only other user of either
of these. As other users of skb->decrypted come along, they can be added
to sk_has_decrypt_user(). It would make sense to also assert that
sk->sk_validate_xmit_skb() is also NULL in both of these setup paths for
similar future proofing, but the PSP listener/sk_clone() path is still
broken and it could be seen as a regression to not allow rx assoc to run
on a child of a listener socket with PSP tx assoc state.
Include all TCP ULPs in the sk_has_decrypt_user() check, even though TLS
is the only one that conflicts with PSP via the decrypted bit. This is
intentional because PSP was not designed to be used with ULPs. It is
best to close off surface area that may make bugs reachable, until
someone wishes to design and test an actual user of PSP with ULPs. |
| Improper initialization in an ASUS certain motherboard allows an physically proximate user to read or write arbitrary memory by inserting a specially crafted device.

| In the Linux kernel, the following vulnerability has been resolved:
usb: xhci: bail out of setup if the controller is inaccessible
xhci_gen_setup() locates the operational registers using the capability
length read from the very first register:
xhci->op_regs = hcd->regs +
HC_LENGTH(readl(&xhci->cap_regs->hc_capbase));
If the controller is dead or has dropped off the bus, that read returns
~0, HC_LENGTH() truncates it to 0xff, and op_regs ends up 0xff bytes
past the page-aligned MMIO base, i.e. unaligned. The first access
through it, xhci_halt() -> xhci_handshake() reading op_regs->status, is
then an unaligned readl() on device memory. arm64 faults on unaligned
device accesses, so instead of xhci_handshake() catching the all-ones
value and returning -ENODEV, setup oopses:
xhci-pci-renesas 0005:08:00.0: Unable to change power state from D3cold to D0, device inaccessible
xhci-pci-renesas 0005:08:00.0: xHCI Host Controller
xhci-pci-renesas 0005:08:00.0: new USB bus registered, assigned bus number 1
Unable to handle kernel paging request at virtual address ffff80030a770103
ESR = 0x0000000096000021
FSC = 0x21: alignment fault
Internal error: Oops: 0000000096000021 [#1] SMP
pc : xhci_halt [xhci_hcd]
Call trace:
xhci_halt
xhci_gen_setup
xhci_pci_setup
usb_add_hcd
usb_hcd_pci_probe
xhci_pci_common_probe
xhci_pci_renesas_probe
This was hit with a Renesas uPD720201 that failed to power up ("Unable
to change power state from D3cold to D0, device inaccessible") yet still
reached the HCD probe path.
Read the capability register once, and if it reads back the all-ones
value (as xhci_handshake() and xhci_reset() already test for), abort
setup with -ENODEV before op_regs is derived from it. Reading it once
also avoids re-reading a register that may change under a concurrent
hot-removal. |

wifi: iwlwifi: mei: pass correct argument to function
The first argument to iwl_mei_write_cyclic_buf() should be the cldev
but the q_head pointer is passed instead. Fix it. |
