CVSS v3.1 |
| When PHP EXIF extension is parsing EXIF information from an image, e.g. via exif_read_data() function, in PHP versions 7.2.x below 7.2.26, 7.3.x below 7.3.13 and 7.4.0 it is possible to supply it with data what will cause it to read past the allocated buffer. This may lead to information disclosure or crash. |
| In the Linux kernel, the following vulnerability has been resolved:
drm/radeon: fix integer overflow in radeon_align_pitch()
radeon_align_pitch() has the same kind of overflow issue as the old
amdgpu helper: both the alignment round-up add and the final
'aligned * cpp' calculation can overflow signed int.
If that wraps, radeon_mode_dumb_create() can end up returning an
invalid pitch or creating a zero-sized dumb buffer.
Fix this by using check_add_overflow() for the alignment round-up and
check_mul_overflow() for the final pitch calculation, returning 0 on
overflow. Also reject zero pitch and size in
radeon_mode_dumb_create().
Found via AST-based call-graph analysis using sqry. |
| In the Linux kernel, the following vulnerability has been resolved:
ksmbd: use memcmp() to compare ClientGUIDs
ClientGUID is a fixed-size binary value and can contain embedded NUL
bytes. strncmp() stops comparing at the first NUL byte, so different
ClientGUID values can incorrectly be treated as equal.
Use memcmp() in SMB3 multichannel session binding and
FSCTL_VALIDATE_NEGOTIATE_INFO to compare all SMB2_CLIENT_GUID_SIZE
bytes. |
| In the Linux kernel, the following vulnerability has been resolved:
nvme: fix FDP fdpcidx bounds check
The fdpcidx bounds check sets n = NUMFDPC + 1 but used > instead of >=,
incorrectly accepting fdp_idx when it equals n (i.e. NUMFDPC + 1). |
| In the Linux kernel, the following vulnerability has been resolved:
RDMA/rxe: Copy WQE to local buffer in non-SRQ receive path
For non-SRQ QPs, the responder reads WQE fields directly from the
shared queue buffer mapped into userspace. This allows a malicious
user to modify fields like num_sge or sge entries while the kernel
is processing the WQE, leading to out-of-bounds reads in
rxe_resp_check_length() and copy_data().
Introduce get_recv_wqe() that validates num_sge and copies the WQE
to a kernel-local buffer before processing, matching the approach
already used for SRQ WQEs in get_srq_wqe(). The srq_wqe buffer is
reused since SRQ and non-SRQ paths are mutually exclusive per QP. |
| Red Hat CNA-LR concluded that this CVE is not valid. |
| In the Linux kernel, the following vulnerability has been resolved:
cxl/region: Fix out-of-bounds access in cxl_cancel_auto_attach()
In cxl_cancel_auto_attach(), it assumes cxled->pos is a valid index for
accessing p->targets[]. However, cxled->pos can be set to negative errno
in cxl_region_sort_targets() if cxl_calc_interleave_pos() fails. This
causes the driver to use a negative index to access p->targets[],
resulting in out-of-bounds access.
Fix it by walking p->targets[] instead of using cxled->pos directly. |
| In the Linux kernel, the following vulnerability has been resolved:
RDMA/mlx5: Fix undefined shift of user RQ WQE size
set_rq_size() computes the RQ WQE size as "1 << rq_wqe_shift" based on
the user-provided rq_wqe_shift, which is only checked to be greater than
32, so shifts of 32 are still accepted. A shift of 31 also overflows a
signed integer, leading to undefined behavior.
Use check_shl_overflow() to compute the RQ WQE size and reject any
invalid values. |
| In the Linux kernel, the following vulnerability has been resolved:
rxrpc: Don't move a peeked OOB message onto the pending queue
rxrpc_recvmsg_oob() takes a received oob message off recvmsg_oobq and,
if a response is needed, moves it onto the pending_oobq tree. However,
only the unlink from recvmsg_oobq is guarded by MSG_PEEK; the move onto
pending_oobq always runs.
As a result, reading a challenge with MSG_PEEK leaves the skb on
recvmsg_oobq while also adding it to pending_oobq. Since struct
sk_buff's rbnode shares storage with its next and prev pointers,
rb_insert_color() overwrites the list linkage, and the skb, which holds
a single reference, becomes reachable from both queues at once.
When the socket is closed both queues are drained in turn. While
draining recvmsg_oobq, __skb_unlink() follows the next and prev
pointers that rbnode has overwritten and writes to a bad address. Also,
as the skb holds a single reference but is freed from each queue, both
the skb and the connection reference it holds are released twice. This
leads to memory corruption and to a use-after-free caused by the
connection refcount underflow.
MSG_PEEK does not consume the message from the queue, so only unlink it
from recvmsg_oobq and then move it onto pending_oobq or free it when
the message is actually consumed. |
| A maliciously crafted DWG or DXF file, when parsed through Autodesk AutoCAD, can force an Out-of-Bounds Read vulnerability. A malicious actor can leverage this vulnerability to cause a crash or disclose sensitive information. |
| In the Linux kernel, the following vulnerability has been resolved:
wifi: wcn36xx: fix heap overflow from oversized firmware HAL response
The firmware response dispatcher copies all synchronous HAL responses
into the 4096-byte hal_buf without validating the response length. A
response exceeding WCN36XX_HAL_BUF_SIZE causes a heap buffer overflow
with firmware-controlled content.
Add a bounds check on the response length. |
| In the Linux kernel, the following vulnerability has been resolved:
wifi: ath9k: fix OOB access from firmware tx status queue ID
ath_tx_edma_tasklet() accesses sc->tx.txq[ts.qid] where ts.qid is a
4-bit hardware field (0-15), but the txq array only has
ATH9K_NUM_TX_QUEUES (10) entries. A qid >= 10 causes an OOB array
access.
Add a bounds check on ts.qid before using it as an array index. |
| In the Linux kernel, the following vulnerability has been resolved:
wifi: rtw89: Correct data type for scan index to avoid infinite loop
A kernel soft lockup was observed during Wi-Fi scanning on the 6GHz band.
The CPU becomes stuck in rtw89_hw_scan_add_chan_ax for over 20 seconds,
leading to a system panic.
RIP points to 0f b6 c3 (movzbl %bl, %eax), which zero-extends
the low 8 bits of RBX into RAX.
RBX (the counter i) has reached a huge value: 0x137466a1.

| In the Linux kernel, the following vulnerability has been resolved:
afs: handle CB.InitCallBackState3 requests without a server record
The cache manager callback path now attaches the server record to an
incoming call through the rxrpc peer's app data. That association is
not guaranteed to exist for every callback request, and most callback
handlers already tolerate that case.
Make CB.InitCallBackState3 follow the same pattern by checking whether a
server record was attached before using it. If the peer is not mapped
to a server record, trace the request and ignore it, matching the
existing behaviour for other unmatched callback requests.
This keeps the callback handler consistent with the rest of the cache
manager service and avoids depending on peer state that may not be
available for a given request. |

crypto: marvell/octeontx - fix DMA cleanup using wrong loop index
The sg_cleanup path used list[i] instead of list[j] when unmapping DMA
buffers, leaking successfully mapped entries and repeatedly unmapping
the failed one. |
| In Eclipse Theia versions up to and including 1.69.0, opening a folder starts source control integration without requiring the user to trust the folder first. This affects applications built on Theia that include the git integration, such as the Theia IDE. Both Theia's own `@theia/git` extension and the builtin VS Code `git` extension run git commands such as `git status` as soon as a repository is detected. Since git honors repository-local configuration, a folder containing an attacker-controlled `.git/config` with `core.fsmonitor` (or a comparable hook-like setting) causes the configured command to be executed. The configuration can be delivered by burying a bare repository inside a regular repository (OVE-20210718-0001), so cloning an attacker-supplied repository and opening it in a Theia-based application is sufficient to execute arbitrary commands with the privileges of the user, without any confirmation prompt.
As of 1.70.0, plugins that declare `capabilities.untrustedWorkspaces.supported: false`, which includes the builtin git extension, are no longer loaded or activated in an untrusted workspace, and the deprecated `@theia/git` extension has been removed, so no git command is executed against an untrusted folder. |

vdpa/octeon_ep: fix IRQ-to-ring mapping in interrupt handler
Look up the IRQ index in oct_hw->irqs instead of assuming
irq - irqs[0]. This supports non-contiguous IRQ numbers and
avoids incorrect ring indexing when irqs[0] is not the base. |
| In the Linux kernel, the following vulnerability has been resolved:
ASoC: amd: acp-sdw-legacy: Bound DAI link iteration
create_sdw_dailinks() walks soc_dais until it finds an entry with
initialised cleared, but soc_dais is allocated with exactly num_ends
entries. If all entries are initialised, the loop reads past the end of
the array.
This was reported by KASAN:
BUG: KASAN: slab-out-of-bounds in mc_probe+0x26b3/0x2774 [snd_acp_sdw_legacy_mach]
Read of size 1
Pass the allocated entry count to create_sdw_dailinks() and stop before
reading past the array. |
| In the Linux kernel, the following vulnerability has been resolved:
drm/panthor: reject firmware sections with oversized data
In panthor_fw_load_section_entry(), the data size to copy is calculated
without validating it against the allocated section_size:
section->data.size = hdr.data.end - hdr.data.start;
If a crafted firmware sets data.size larger than the allocated memory,
this could cause a heap buffer overflow in panthor_fw_init_section_mem()
memcpy(section->mem->kmap, section->data.buf, section->data.size);
Additionally, if the section->data.size exceeds the BO size, could this
memset underflow the size calculation, leading to a massive out-of-bounds
zeroing of kernel memory?
memset(section->mem->kmap + section->data.size, 0,
panthor_kernel_bo_size(section->mem) - section->data.size);
Reject section entries whose initial data is larger than the section size. |
