CVSS v3.1 |
| In the Linux kernel, the following vulnerability has been resolved:
HID: bpf: prevent buffer overflow in hid_hw_request
right now the returned value is considered to be always valid. However,
when playing with HID-BPF, the return value can be arbitrary big,
because it's the return value of dispatch_hid_bpf_raw_requests(), which
calls the struct_ops and we have no guarantees that the value makes
sense. |
| In the Linux kernel, the following vulnerability has been resolved:
tracing/dma: Cap dma_map_sg tracepoint arrays to prevent buffer overflow
The dma_map_sg tracepoint can trigger a perf buffer overflow when
tracing large scatter-gather lists. With devices like virtio-gpu
creating large DRM buffers, nents can exceed 1000 entries, resulting
in:
phys_addrs: 1000 * 8 bytes = 8,000 bytes
dma_addrs: 1000 * 8 bytes = 8,000 bytes
lengths: 1000 * 4 bytes = 4,000 bytes
Total: ~20,000 bytes
This exceeds PERF_MAX_TRACE_SIZE (8192 bytes), causing:
WARNING: CPU: 0 PID: 5497 at kernel/trace/trace_event_perf.c:405
perf buffer not large enough, wanted 24620, have 8192
Cap all three dynamic arrays at 128 entries using min() in the array
size calculation. This ensures arrays are only as large as needed
(up to the cap), avoiding unnecessary memory allocation for small
operations while preventing overflow for large ones.
The tracepoint now records the full nents/ents counts and a truncated
flag so users can see when data has been capped.
Changes in v2:
- Use min(nents, DMA_TRACE_MAX_ENTRIES) for dynamic array sizing
instead of fixed DMA_TRACE_MAX_ENTRIES allocation (feedback from
Steven Rostedt)
- This allocates only what's needed up to the cap, avoiding waste
for small operations

| Delta Electronics AS320T has incorrect calculation of the buffer size on the stack in the GET/PUT request handler of the web service. |
| Libgcrypt before 1.12.2 sometimes allows a heap-based buffer overflow and denial of service via crafted ECDH ciphertext to gcry_pk_decrypt. |
| In the Linux kernel, the following vulnerability has been resolved:
can: usb: f81604: handle short interrupt urb messages properly
If an interrupt urb is received that is not the correct length, properly
detect it and don't attempt to treat the data as valid. |
| In the Linux kernel, the following vulnerability has been resolved:
net: usb: cdc_ncm: add ndpoffset to NDP32 nframes bounds check
The same bounds-check bug fixed for NDP16 in the previous patch also
exists in cdc_ncm_rx_verify_ndp32(). The DPE array size is validated
against the total skb length without accounting for ndpoffset, allowing
out-of-bounds reads when the NDP32 is placed near the end of the NTB.
Add ndpoffset to the nframes bounds check and use struct_size_t() to
express the NDP-plus-DPE-array size more clearly.

| Calling the scanf family of functions with a %mc (malloc'd character match) in the GNU C Library version 2.7 to version 2.43 with a format width specifier with an explicit width greater than 1024 could result in a one byte heap buffer overflow. |
| The init_request_info function in sapi/cgi/cgi_main.c in PHP before 5.2.6 does not properly consider operator precedence when calculating the length of PATH_TRANSLATED, which might allow remote attackers to execute arbitrary code via a crafted URI. |
| A flaw has been found in pnggroup libpng up to 1.6.55. Affected by this vulnerability is the function do_pnm2png of the file contrib/pngminus/pnm2png.c of the component pnm2png. This manipulation of the argument width/height causes heap-based buffer overflow. The attack is restricted to local execution. The exploit has been published and may be used. The project was informed of the problem early through an issue report but has not responded yet. |
| Incorrect boundary conditions in the WebRTC component. This vulnerability was fixed in Firefox 150, Firefox ESR 115.35, Firefox ESR 140.10, Thunderbird 150, and Thunderbird 140.10. |
| Incorrect boundary conditions in the WebRTC: Networking component. This vulnerability was fixed in Firefox 150, Firefox ESR 140.10, Thunderbird 150, and Thunderbird 140.10. |
| Out-of-bounds write in Azure Monitor Agent allows an authorized attacker to execute code over a network. |
| A vulnerability was determined in libvips up to 8.19.0. The affected element is the function vips_source_read_to_memory of the file libvips/iofuncs/source.c. This manipulation causes heap-based buffer overflow. It is possible to launch the attack on the local host. The attack's complexity is rated as high. The exploitability is described as difficult. The exploit has been publicly disclosed and may be utilized. Patch name: a56feecbe9ed66521d9647ec9fbcd2546eccd7ee. Applying a patch is the recommended action to fix this issue. The confirmation of the bugfix mentions: "[T]he impact of this is negligible, since this only affects custom seekable sources larger than 4 GiB (and the crash occurs in user code rather than libvips itself)." |
| iccDEV provides a set of libraries and tools that allow for the interaction, manipulation, and application of ICC color management profiles. Prior to version 2.3.1.2, iccDEV has undefined behavior due to a null pointer passed to memcpy() in CIccTagSparseMatrixArray. This issue has been patched in version 2.3.1.2. |
| FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.22.0, audin_server_recv_formats frees an incorrect number of audio formats on parse failure (i + i), leading to out-of-bounds access in audio_formats_free. This vulnerability is fixed in 3.22.0. |
| HDF5 is software for managing data. Prior to version 1.14.4-2, an attacker who can control an `h5` file parsed by HDF5 can trigger a write-based heap buffer overflow condition. This can lead to a denial-of-service condition, and potentially further issues such as remote code execution depending on the practical exploitability of the heap overflow against modern operating systems. Real-world exploitability of this issue in terms of remote-code execution is currently unknown. Version 1.14.4-2 fixes the issue. |
| GIMP ICNS File Parsing Heap-based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of GIMP. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.
The specific flaw exists within the parsing of ICNS files. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a heap-based buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-28530. |
| openCryptoki is a PKCS#11 library and tools for Linux and AIX. In 3.25.0 and 3.26.0, there is a heap buffer overflow vulnerability in the CKM_ECDH_AES_KEY_WRAP implementation allows an attacker with local access to cause out-of-bounds writes in the host process by supplying a compressed EC public key and invoking C_WrapKey. This can lead to heap corruption, or denial-of-service. |
| In the Eclipse OMR port library component since release 0.2.0, an API function to return the textual names of all supported processor features was not accounting for the separator inserted between processor features. If the output buffer supplied to this function was incorrectly sized, failing to account for the separator when determining when a write to the buffer was safe could lead to a buffer overflow. This issue is fixed in Eclipse OMR version 0.8.0. |
| FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.22.0, the RDPSND async playback thread can process queued PDUs after the channel is closed and internal state is freed, leading to a use after free in rdpsnd_treat_wave. This vulnerability is fixed in 3.22.0. |
