CVE-2026-42479 1 Opencascade 1 Open Cascade Technology 2026-05-02 5.5 Medium
An out-of-bounds read vulnerability in VrmlData_IndexedLineSet::TShape in the VRML parser in Open CASCADE Technology (OCCT) V8_0_0_rc5 allows attackers to cause a denial of service via a crafted VRML file. The issue occurs because coordIndex values from parsed input are used as direct array indices without validation against the size of the coordinate array during geometry processing.
CVE-2026-31764 1 Linux 1 Linux Kernel 2026-05-01 N/A
In the Linux kernel, the following vulnerability has been resolved: iio: imu: st_lsm6dsx: Set buffer sampling frequency for accelerometer only The st_lsm6dsx_hwfifo_odr_store() function, which is called when userspace writes the buffer sampling frequency sysfs attribute, calls st_lsm6dsx_check_odr(), which accesses the odr_table array at index `sensor->id`; since this array is only 2 entries long, an access for any sensor type other than accelerometer or gyroscope is an out-of-bounds access. The motivation for being able to set a buffer frequency different from the sensor sampling frequency is to support use cases that need accurate event detection (which requires a high sampling frequency) while retrieving sensor data at low frequency. Since all the supported event types are generated from acceleration data only, do not create the buffer sampling frequency attribute for sensor types other than the accelerometer.
CVE-2026-5673 2 Redhat, Xiph 3 Enterprise Linux, Libtheora, Theora 2026-05-01 5.6 Medium
A flaw was found in libtheora. This heap-based out-of-bounds read vulnerability exists within the AVI (Audio Video Interleave) parser, specifically in the avi_parse_input_file() function. A local attacker could exploit this by tricking a user into opening a specially crafted AVI file containing a truncated header sub-chunk. This could lead to a denial-of-service (application crash) or potentially leak sensitive information from the heap.
CVE-2026-28532 1 Frrouting 1 Frrouting 2026-05-01 6.5 Medium
FRRouting before 10.5.3 contains an integer overflow vulnerability in seven OSPF Traffic Engineering and Segment Routing TLV parser functions where a uint16_t accumulator variable truncates uint32_t values returned by the TLV_SIZE() macro, causing the loop termination condition to fail while pointer advancement continues unchecked. Attackers with an established OSPF adjacency can send a crafted LS Update packet with a malicious Type 10 or Type 11 Opaque LSA to trigger out-of-bounds memory reads and crash all affected routers in the OSPF area or autonomous system.
CVE-2026-23865 1 Freetype 1 Freetype 2026-05-01 5.3 Medium
An integer overflow in the tt_var_load_item_variation_store function of the Freetype library in versions 2.13.2 and 2.13.3 may allow for an out of bounds read operation when parsing HVAR/VVAR/MVAR tables in OpenType variable fonts. This issue is fixed in version 2.14.2.
CVE-2026-40686 1 Exim 1 Exim 2026-05-01 3.7 Low

Performing a manipulation results in out-of-bounds read. Remote exploitation of the attack is possible. The exploit has been made public and could be used. The vendor was contacted early about this disclosure but did not respond in any way.
CVE-2026-5928 2 Gnu, The Gnu C Library 2 Glibc, Glibc 2026-04-30 7.5 High
Calling the ungetwc function on a FILE stream with wide characters encoded in a character set that has overlaps between its single byte and multi-byte character encodings, in the GNU C Library version 2.43 or earlier, may result in an attempt to read bytes before an allocated buffer, potentially resulting in unintentional disclosure of neighboring data in the heap, or a program crash. A bug in the wide character pushback implementation (_IO_wdefault_pbackfail in libio/wgenops.c) causes ungetwc() to operate on the regular character buffer (fp->_IO_read_ptr) instead of the actual wide-stream read pointer (fp->_wide_data->_IO_read_ptr). The program crash may happen in cases where fp->_IO_read_ptr is not initialized and hence points to NULL. The buffer under-read requires a special situation where the input character encoding is such that there are overlaps between single byte representations and multibyte representations in that encoding, resulting in spurious matches. The spurious match case is not possible in the standard Unicode character sets.
CVE-2026-2810 1 Netskope 1 Client 2026-04-30 N/A
Netskope was notified about a potential gap in the Endpoint DLP Module for Netskope Client on Windows systems. The successful exploitation of the gap can potentially allow an unprivileged user to trigger an out-of-bounds read within a driver, leading to a Blue-Screen-of-Death (BSOD). Successful exploitation would require the Endpoint DLP module to be enabled in the client configuration. A successful exploit can potentially result in a denial-of-service for the local machine.

Out-of-bounds read in Microsoft Office Word allows an unauthorized attacker to disclose information locally.
CVE-2026-32188 1 Microsoft 11 365 Apps, Excel, Excel 2016 and 8 more 2026-04-29 7.1 High
Out-of-bounds read in Microsoft Office Excel allows an unauthorized attacker to disclose information locally.
CVE-2026-31614 1 Linux 1 Linux Kernel 2026-04-29 7.1 High
In the Linux kernel, the following vulnerability has been resolved: smb: client: fix off-by-8 bounds check in check_wsl_eas() The bounds check uses (u8 *)ea + nlen + 1 + vlen as the end of the EA name and value, but ea_data sits at offset sizeof(struct smb2_file_full_ea_info) = 8 from ea, not at offset 0. The strncmp() later reads ea->ea_data[0..nlen-1] and the value bytes follow at ea_data[nlen+1..nlen+vlen], so the actual end is ea->ea_data + nlen + 1 + vlen. Isn't pointer math fun? The earlier check (u8 *)ea > end - sizeof(*ea) only guarantees the 8-byte header is in bounds, but since the last EA is placed within 8 bytes of the end of the response, the name and value bytes are read past the end of iov. Fix this mess all up by using ea->ea_data as the base for the bounds check. An "untrusted" server can use this to leak up to 8 bytes of kernel heap into the EA name comparison and influence which WSL xattr the data is interpreted as.
CVE-2026-4159 1 Wolfssl 1 Wolfssl 2026-04-29 3.3 Low
