CVSS v3.1 |
| CompressionUtils.inflate() decompressed attacker-controlled DEFLATE data with no output-size cap. A small (~KB) crafted payload could expand to gigabytes on the heap. Reachable via JWE decryption when zip=DEF (e.g. JoseSessionTokenProvider with RSA-OAEP key wrap) and via SAML redirect/POST binding token inflation — in both cases decompression happens before/independent of trust validation.
Fix: Added a configurable maximum inflated-size cap (default 10 MiB, org.apache.cxf.compression-max-inflated-size system property) to CompressionUtils.inflate(); aborts with DataFormatException once exceeded.
Users are recommended to upgrade to versions 4.2.4 or 4.1.9 or 3.6.13, which fix this issue. |

nvmet: fix max_qid race between configfs and controller allocation
The function nvmet_subsys_attr_qid_max_store() can race against
nvmet_alloc_ctrl() when a subsystem's max_qid limit is modified.
Suppose max_qid is currently 64. If nvmet_alloc_ctrl() executes:
ctrl->sqs = kzalloc_objs(struct nvmet_sq *, subsys->max_qid + 1);
and at this exact point, a userspace process changes max_qid to 128,
nvmet_subsys_attr_qid_max_store() will set the new max_qid value. It
attempts to delete active controllers to force a reconnect, but the
new controller won't be deleted because it hasn't been added to the
subsys->ctrls list yet.
nvmet_alloc_ctrl() then proceeds and adds the new controller to the
subsys->ctrls list. Later, when nvmet_install_queue() is called, it
will see max_qid set to 128, but the memory allocated for sqs is only
sized for 64 entries. This results in a KASAN out-of-bounds warning
and potential memory corruptions.
Fix this by protecting the queue allocations and list insertion in
nvmet_alloc_ctrl() with down_read(&nvmet_config_sem). Because
nvmet_subsys_attr_qid_max_store() acquires down_write(&nvmet_config_sem)
to modify the attribute, this safely prevents the configfs writer from
modifying max_qid during controller creation.
Copy the max_qid from the subsystem to the controller's structure
during the allocation; ctrl->max_qid never changes as long as the
controller remains in LIVE state, so this will prevent similar race
conditions. |

net: mana: Cap MSI-X vectors to the device MSI-X table size
mana_gd_query_max_resources() sizes gc->num_msix_usable from resp.max_msix
and the CPU count, but never from the device MSI-X table. On a 1792 vCPU
M-series VM that yields 1793 while the table has 1024 entries, and
mana_gd_setup_remaining_irqs() then walks indices 1..1792, running off the

btrfs: lzo: reject compressed segment that overflows the compressed input
lzo_decompress_bio() validates each on-disk segment length seg_len only
against the workspace cbuf size, not against the compressed input size
(compressed_len, the total folio bytes of the bio). A crafted extent can
carry a segment whose seg_len passes the cbuf check but runs past the end
of the bio, so copy_compressed_segment() walks off the last folio:
get_current_folio() then returns the NULL folio from bio_next_folio(), and
with CONFIG_BTRFS_ASSERT disabled (default) folio_size(NULL) faults.

smb: client: fix missing iov bounds check in parse_posix_sids()
In parse_posix_sids(), sidsbuf_end is calculated using the server-supplied
out_len without being validated against the actual length of the received
iov (iov_len).
If a server provides an inflated out_len, sidsbuf_end will point past the
end of the iov. This defeats the bounds guards in posix_info_sid_size(),
allowing out-of-bounds reads into adjacent kernel memory.
Fix this by rejecting responses where the calculated sidsbuf_end would
exceed the received iov boundaries or cause pointer wraparound. |
| In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: btintel_pcie: fix tx_handle bounds off-by-one
Valid indices into txq->urbd0s/tfds/bufs are 0..txq->count-1, so
tfd_index == txq->count is already out of range. Change the guard in
btintel_pcie_msix_tx_handle() from '> txq->count' to '>= txq->count'.
This issue was reported by Claude Mythos. |

mtd: spi-nor: debugfs: fix out-of-bounds read in spi_nor_params_show()
Sashiko noticed an out-of-bounds read [1].
In spi_nor_params_show(), the snor_f_names array is passed to
spi_nor_print_flags() using sizeof(snor_f_names).
Since snor_f_names is an array of pointers, sizeof() returns the total
number of bytes occupied by the pointers
(element_count * sizeof(void *))
rather than the element count itself. On 64-bit systems, this makes the
passed length 8x larger than intended.
Inside spi_nor_print_flags(), the 'names_len' argument is used to
bounds-check the 'names' array access. An out-of-bounds read occurs
if a flag bit is set that exceeds the array's actual element count
but is within the inflated byte-size count.
Correct this by using ARRAY_SIZE() to pass the actual number of
string pointers in the array. |
| In the Linux kernel, the following vulnerability has been resolved:
bridge: br_nd_send: linearize skb before parsing ND options
br_nd_send() parses neighbour discovery options from ns->opt[] and
assumes that these options are in the linear part of request.
Its callers only guarantee that the ICMPv6 header and target address
are available, so the option area can still be non-linear. Parsing
ns->opt[] in that case can access data past the linear buffer.
Linearize request before option parsing and derive ns from the linear
network header. |
| Use-after-free in the Crash Reporting component. This vulnerability was fixed in Firefox 158, Firefox ESR 153.5, Thunderbird 158, and Thunderbird 153.5. |
| Out-of-bounds read and write in lib_sag_ai_sound_sep_v2.00.so prior to SMR Oct-2026 Release 1 allows local attackers to read and write out-of-bounds memory. |
| In the Linux kernel, the following vulnerability has been resolved:
vdpa_sim_blk: reject out-of-range sector starts
vdpasim_blk_check_range() logs an invalid start sector but continues
validating the request. The subsequent unsigned capacity subtraction can
underflow and let an out-of-range buffer offset reach the data path.
The invalid offset is used by three request paths. VIRTIO_BLK_T_OUT
copies guest data to blk->buffer + offset through
vringh_iov_pull_iotlb(), causing an out-of-bounds write in
_copy_from_iter() or memcpy(). VIRTIO_BLK_T_IN copies from
blk->buffer + offset to the guest through vringh_iov_push_iotlb(),
causing an out-of-bounds read in _copy_to_iter().
VIRTIO_BLK_T_WRITE_ZEROES passes blk->buffer + offset to memset(),
causing an out-of-bounds write.
Reject starts at or beyond the capacity before the subtraction. Treat the
capacity boundary as invalid because the IN and OUT paths round byte counts
down to sectors for validation but later copy the original byte counts. A
sub-sector request at the capacity boundary would otherwise still access
past the end of the buffer.
I found this bug myself, though the patch was written with AI assistance. |
| In the Linux kernel, the following vulnerability has been resolved:
mptcp: syncookies: remember the request backup flag
Instead of using an uninitialised bit when copying the info in
subflow_ulp_clone().
To fix this, no need to extend the join_entry structure: backup is
coming from struct mptcp_subflow_request_sock, only one bit. Do the same
here by using one bit for both. |

wifi: cfg80211: validate IEs in cfg80211_wext_siwgenie()
The KASAN allocation trace shows that a malformed IE buffer is
stored via SIOCSIWGENIE (cfg80211_wext_siwgenie()) without any
validation. The crash trace shows that a subsequent SIOCSIWESSID
triggers a connection attempt which calls cfg80211_sme_get_conn_ies()
to process the stored IE buffer, causing:
- An out-of-bounds read in skip_ie() which reads ies[pos+1]
(the length byte) past the end of the 1-byte buffer.
- An integer underflow in the memcpy size argument when offs
returned by ieee80211_ie_split() exceeds ies_len, causing
unsigned subtraction to wrap to SIZE_MAX and triggering a
fortify panic.
Fix this by validating the IE buffer in cfg80211_wext_siwgenie()
before storing it.

Bluetooth: RFCOMM: validate skb length in rfcomm_recv_frame
rfcomm_recv_frame() casts skb->data to struct rfcomm_hdr and dereferences
hdr->addr and hdr->ctrl without validating skb->len first. A truncated
frame with skb->len less than the minimum header size causes an
out-of-bounds read of uninitialized memory. Additionally, a zero-length
frame causes skb->len-- to underflow to UINT_MAX, making
skb_tail_pointer() read far past the buffer.
Commit 23882b828c3c ("Bluetooth: RFCOMM: validate skb length in MCC
handlers") fixed the same class of missing-length-check bugs in the MCC
sub-handlers, but the top-level rfcomm_recv_frame() was left unfixed.
KMSAN reports:
BUG: KMSAN: uninit-value in rfcomm_run
...
Uninit was created at:
__alloc_skb+0x474/0xb60
vhci_write+0xe9/0x870
Fix this by rejecting frames smaller than sizeof(struct rfcomm_hdr) + 1
(the minimum frame must have a 3-byte header and a 1-byte FCS). |
| In the Linux kernel, the following vulnerability has been resolved:
vxlan: initialize _md in vxlan_xmit_one()
If a VXLAN device is configured with both VXLAN_F_COLLECT_METADATA and
VXLAN_F_GBP, and a packet is transmitted through it using an external
ip_tunnel_info that lacks the IP_TUNNEL_VXLAN_OPT_BIT flag, md is left
pointing to the uninitialized _md stack variable:
if (test_bit(IP_TUNNEL_VXLAN_OPT_BIT, info->key.tun_flags)) {
if (info->options_len < sizeof(*md))
goto drop;
md = ip_tunnel_info_opts(info);
}
Because IP_TUNNEL_VXLAN_OPT_BIT is not set, md is not updated and remains
pointing to _md. Later, vxlan_build_skb() is called with md, which
eventually calls vxlan_build_gbp_hdr():
if (vxflags & VXLAN_F_GBP)
vxlan_build_gbp_hdr(vxh, md);
Inside vxlan_build_gbp_hdr(), md->gbp is read:
if (!md->gbp)
return;
gbp = (struct vxlanhdr_gbp *)vxh;
...
if (md->gbp & VXLAN_GBP_DONT_LEARN)
gbp->dont_learn = 1;
If the stack contains garbage, this causes:
1) VXLAN_HF_GBP flag to be spuriously set in the VXLAN header.
2) gbp->dont_learn and gbp->policy_applied to be set from stack bits.
3) gbp->policy_id to receive 16 bits of uninitialized kernel stack data,
leaking it onto the wire.
Fix this by zero-initializing _md. If IP_TUNNEL_VXLAN_OPT_BIT is not
present, md->gbp remains 0, and vxlan_build_gbp_hdr() returns early
without modifying the VXLAN header. |

perf/x86/intel: Prevent drain_pebs() reentry
The PEBS buffer is shared by all events on a CPU, so drain_pebs() must
not be reentered. If so, one instance may observe stale buffer state and
potentially access out-of-bound memory.
Most invocations happen in NMI context, which naturally prevents reentry.
However, drain_pebs() is also reachable from process context via
intel_pmu_drain_pebs_buffer().
In those paths, the PMU is often already disabled, but not guaranteed.
For example, __intel_pmu_pebs_disable() only disables the target counter,
so other active counters can still raise a PMI and interrupt an in-flight
drain_pebs(). Here is an example,
__perf_addr_filters_adjust()
perf_event_stop()
__perf_event_stop()
x86_pmu_stop() (event->pmu->stop)
intel_pmu_disable_event()
intel_pmu_pebs_disable()
__intel_pmu_pebs_disable()
intel_pmu_drain_large_pebs()
intel_pmu_drain_pebs_buffer()
Introduce __intel_pmu_quiesce() and __intel_pmu_resume() helpers and
use them in intel_pmu_drain_large_pebs() to disable the full PMU
around the intel_pmu_drain_pebs_buffer() call, preventing reentry.
Also add a warning in intel_pmu_drain_pebs_buffer() when the full PMU is
not disabled. |

accel/ivpu: Validate firmware log buffer metadata
The tracing log headers parsed by fw_log_print_buffer() reside in
DMA-shared BOs that the NPU firmware can write to.
fw_log_from_bo() validated log->header_size and log->size, but
fw_log_print_buffer() re-read those same fields from shared memory
afterwards, allowing a TOCTOU where firmware changes them between the
check and the use, and making the host dereference out-of-bounds
addresses while printing logs.
Snapshot the validated values once with READ_ONCE() and pass them down
explicitly in a new struct ivpu_fw_log_desc instead of re-reading them
from the shared struct. |
| In the Linux kernel, the following vulnerability has been resolved:
ipmi: ipmb: validate write message length
ipmb_write() read message fields before validating the length byte.
A zero or short write can read uninitialized stack bytes.
A length smaller than the SMBus header underflows the block write length.
Require a non-empty buffer and the minimum IPMB request length.
Also require the length byte plus payload before parsing the message. |

drm/amdgpu/pm/powerplay: bounds-check voltage index in Vega10 lookup
vddInd, vddciInd and mvddInd from VBIOS-parsed tables index into vddc,
vddci and vddmem lookup tables without bounds checks across nine sites.
Return -EINVAL when any index is out of range. |
| In the Linux kernel, the following vulnerability has been resolved:
nilfs2: prevent out-of-bounds read in super root block parsing
super-root inode metadata size is trusted before nilfs_read_inode_common().
Reject super-root inode sizes whose computed on-disk footprint exceeds the
filesystem block size. This prevents malformed filesystem images from
making nilfs_read_inode_common() read past the end of the super-root block.
