CVSS v3.1 |
| An out-of-bounds access issue was addressed with improved bounds checking. This issue is fixed in iPadOS 17.7.4, visionOS 2.2, tvOS 18.2, watchOS 11.2, iOS 18.2 and iPadOS 18.2, macOS Sonoma 14.7.2, macOS Sequoia 15.2. Processing maliciously crafted web content may lead to an unexpected process crash. |
| In the Linux kernel, the following vulnerability has been resolved:
vfio/pci: Properly hide first-in-list PCIe extended capability
There are cases where a PCIe extended capability should be hidden from
the user. For example, an unknown capability (i.e., capability with ID
greater than PCI_EXT_CAP_ID_MAX) or a capability that is intentionally
chosen to be hidden from the user.
Hiding a capability is done by virtualizing and modifying the 'Next
Capability Offset' field of the previous capability so it points to the
capability after the one that should be hidden.
The special case where the first capability in the list should be hidden
is handled differently because there is no previous capability that can
be modified. In this case, the capability ID and version are zeroed
while leaving the next pointer intact. This hides the capability and
leaves an anchor for the rest of the capability list.
However, today, hiding the first capability in the list is not done
properly if the capability is unknown, as struct
vfio_pci_core_device->pci_config_map is set to the capability ID during
initialization but the capability ID is not properly checked later when
used in vfio_config_do_rw(). This leads to the following warning [1] and
to an out-of-bounds access to ecap_perms array.
Fix it by checking cap_id in vfio_config_do_rw(), and if it is greater
than PCI_EXT_CAP_ID_MAX, use an alternative struct perm_bits for direct
read only access instead of the ecap_perms array.
Note that this is safe since the above is the only case where cap_id can
exceed PCI_EXT_CAP_ID_MAX (except for the special capabilities, which
are already checked before).

| In the Linux kernel, the following vulnerability has been resolved:
soc: qcom: geni-se: fix array underflow in geni_se_clk_tbl_get()
This loop is supposed to break if the frequency returned from
clk_round_rate() is the same as on the previous iteration. However,
that check doesn't make sense on the first iteration through the loop.
It leads to reading before the start of these->clk_perf_tbl[] array. |

I found the following bug in my fuzzer:

Since this bug has been confirmed to be caused by insufficient verification
of conn_rsp_epid, I think it would be appropriate to add a range check for
conn_rsp_epid to htc_connect_service() to prevent the bug from occurring. |
| In the Linux kernel, the following vulnerability has been resolved:
bpf: Check validity of link->type in bpf_link_show_fdinfo()
If a newly-added link type doesn't invoke BPF_LINK_TYPE(), accessing
bpf_link_type_strs[link->type] may result in an out-of-bounds access.
To spot such missed invocations early in the future, checking the
validity of link->type in bpf_link_show_fdinfo() and emitting a warning
when such invocations are missed. |
| In the Linux kernel, the following vulnerability has been resolved:
igb: Fix potential invalid memory access in igb_init_module()
The pci_register_driver() can fail and when this happened, the dca_notifier
needs to be unregistered, otherwise the dca_notifier can be called when
igb fails to install, resulting to invalid memory access. |
| The NVMe driver queue processing is vulernable to guest-induced infinite loops. |
| The hda driver is vulnerable to a buffer over-read from a guest-controlled value. |
| A guest can trigger an infinite loop in the hda audio driver. |
| The NVMe driver function nvme_opc_get_log_page is vulnerable to a buffer over-read from a guest-controlled value. |
| In the Linux kernel, the following vulnerability has been resolved:
ntfs3: Add bounds checking to mi_enum_attr()
Added bounds checking to make sure that every attr don't stray beyond
valid memory region. |
| In the Linux kernel, the following vulnerability has been resolved:
cifs: Fix buffer overflow when parsing NFS reparse points
ReparseDataLength is sum of the InodeType size and DataBuffer size.
So to get DataBuffer size it is needed to subtract InodeType's size from
ReparseDataLength.
Function cifs_strndup_from_utf16() is currentlly accessing buf->DataBuffer
at position after the end of the buffer because it does not subtract
InodeType size from the length. Fix this problem and correctly subtract
variable len.
Member InodeType is present only when reparse buffer is large enough. Check
for ReparseDataLength before accessing InodeType to prevent another invalid
memory access.
Major and minor rdev values are present also only when reparse buffer is
large enough. Check for reparse buffer size before calling reparse_mkdev(). |

| GStreamer is a library for constructing graphs of media-handling components. An OOB-read vulnerability has been discovered in gst_wavparse_adtl_chunk within gstwavparse.c. This vulnerability arises due to insufficient validation of the size parameter, which can exceed the bounds of the data buffer. As a result, an OOB read occurs in the following while loop. This vulnerability can result in reading up to 4GB of process memory or potentially causing a segmentation fault (SEGV) when accessing invalid memory. This vulnerability is fixed in 1.24.10. |
| GStreamer is a library for constructing graphs of media-handling components. An OOB-read vulnerability has been identified in the gst_wavparse_smpl_chunk function within gstwavparse.c. This function attempts to read 4 bytes from the data + 12 offset without checking if the size of the data buffer is sufficient. If the buffer is too small, the function reads beyond its bounds. This vulnerability may result in reading 4 bytes out of the boundaries of the data buffer. This vulnerability is fixed in 1.24.10. |
| GStreamer is a library for constructing graphs of media-handling components. An OOB-read has been discovered in gst_wavparse_cue_chunk within gstwavparse.c. The vulnerability happens due to a discrepancy between the size of the data buffer and the size value provided to the function. This mismatch causes the comparison if (size < 4 + ncues * 24) to fail in some cases, allowing the subsequent loop to access beyond the bounds of the data buffer. The root cause of this discrepancy stems from a miscalculation when clipping the chunk size based on upstream data size. This vulnerability allows reading beyond the bounds of the data buffer, potentially leading to a crash (denial of service) or the leak of sensitive data. This vulnerability is fixed in 1.24.10. |
| GStreamer is a library for constructing graphs of media-handling components. An OOB-read vulnerability has been found in the parse_ds64 function within gstwavparse.c. The parse_ds64 function does not check that the buffer buf contains sufficient data before attempting to read from it, doing multiple GST_READ_UINT32_LE operations without performing boundary checks. This can lead to an OOB-read when buf is smaller than expected. This vulnerability allows reading beyond the bounds of the data buffer, potentially leading to a crash (denial of service) or the leak of sensitive data. This vulnerability is fixed in 1.24.10. |
| GStreamer is a library for constructing graphs of media-handling components. An OOB-read vulnerability has been identified in the gst_avi_subtitle_parse_gab2_chunk function within gstavisubtitle.c. The function reads the name_length value directly from the input file without checking it properly. Then, the a condition, does not properly handle cases where name_length is greater than 0xFFFFFFFF - 17, causing an integer overflow. In such scenario, the function attempts to access memory beyond the buffer leading to an OOB-read. This vulnerability is fixed in 1.24.10. |
| GStreamer is a library for constructing graphs of media-handling components. A null pointer dereference vulnerability has been discovered in the gst_matroska_demux_add_wvpk_header function within matroska-demux.c. This function does not properly check the validity of the stream->codec_priv pointer in the following code. If stream->codec_priv is NULL, the call to GST_READ_UINT16_LE will attempt to dereference a null pointer, leading to a crash of the application. This vulnerability is fixed in 1.24.10. |
| GStreamer is a library for constructing graphs of media-handling components. An OOB-read vulnerability has been discovered in the qtdemux_merge_sample_table function within qtdemux.c. The problem is that the size of the stts buffer isn’t properly checked before reading stts_duration, allowing the program to read 4 bytes beyond the boundaries of stts->data. This vulnerability reads up to 4 bytes past the allocated bounds of the stts array. This vulnerability is fixed in 1.24.10. |
