CVE-2026-44605 1 Redhat 3 Enterprise Linux, Hardened Images, Hummingbird 2026-08-07 5.5 Medium
A flaw was found in the RPM Package Manager (RPM). A local user could be affected by a heap buffer overflow vulnerability when processing a specially crafted NDB database file. This issue arises from an error in how RPM handles certain calculations during file parsing, leading to an incorrect memory allocation. An attacker could leverage this to cause a denial of service, making the system unavailable.
CVE-2026-18839 2 Popt-devel, Redhat 6 Popt-static, Enterprise Linux, Hardened Images and 3 more 2026-08-07 2.2 Low
An integer underflow was found in the popt library when formatting help text for option tables that exceed the terminal width. A local user who can cause an application to print help under those conditions may cause that application to crash or fail to display help, resulting in a denial of service of the affected application.
CVE-2026-58532 1 Microsoft 24 Windows 10 1607, Windows 10 1809, Windows 10 21h2 and 21 more 2026-08-07 7.8 High

CVE-2026-58594 1 Microsoft 24 Windows 10 1607, Windows 10 1809, Windows 10 21h2 and 21 more 2026-08-07 8.8 High
Integer overflow or wraparound in Windows RDP allows an unauthorized attacker to execute code over a network.
CVE-2026-19028 1 Hdfgroup 1 Hdf5 2026-08-07 N/A
H5Z__filter_fletcher32 in H5Zfletcher32.c in HDF5 through 2.3.0 computes the data length to checksum by subtracting the 4-byte trailing checksum size from the input buffer size without checking that the buffer is at least 4 bytes, allowing a size_t underflow. This allows attackers to cause a denial of service (massively out-of-bounds read and application crash in H5_checksum_fletcher32) via a crafted HDF5 file with a Fletcher32-filtered chunk smaller than 4 bytes, triggered via H5Dread, e.g. by the h5ls or h5dump tools.
CVE-2026-19174 1 Google 1 Chrome 2026-08-07 8.8 High
Integer overflow in V8 in Google Chrome prior to 151.0.7922.109 allowed a remote attacker to execute arbitrary code inside a sandbox via a crafted HTML page. (Chromium security severity: High)
CVE-2026-58016 2 Gnome, Redhat 13 Glib, Discovery, Enterprise Linux and 10 more 2026-08-07 7.5 High
A flaw was found in GLib. A state confusion issue exists in g_dbus_node_info_new_for_xml() in the gio/gdbusintrospection.c file when processing malformed D-Bus introspection XML, specifically with a `node` element nested within other elements like `method`, `signal`, `property` or `arg`. This issue can cause an unsigned integer overflow and lead to an out-of-bounds read, resulting in a denial of service.
CVE-2026-45103 1 Opensips 1 Opensips 2026-08-05 7.5 High
OpenSIPS is a Session Initiation Protocol (SIP) server implementation. In versions prior to 3.6.6 and 4.0.0-rc1, the TCP message framing layer parses the Content-Length header using unsigned int arithmetic with no overflow check. When an attacker sends a Content-Length value that overflows unsigned int (e.g., 4294967296), the framing layer computes a wrapped-around value (e.g., 0) and splits the TCP stream at the wrong boundary, causing the body of the first SIP message to be processed as a separate message and enabling SIP message smuggling. Because Content-Length is parsed in the transport layer before authentication, an unauthenticated, network-based attacker can smuggle arbitrary SIP messages over any TCP-based transport (proto_tcp, proto_tls, proto_ws, proto_wss) on any instance with TCP enabled, with no routing-script preconditions. This allows smuggled messages to bypass front-end SBC/proxy security policies, inherit the connection's authentication context, and evade rate limiting. This issue has been fixed in versions 3.6.6 and 4.0.0-rc1.
CVE-2026-66758 2 Gimp, Redhat 2 Gimp, Enterprise Linux 2026-08-05 7.8 High
A flaw was found in the file-fits plugin in GIMP. When processing a FITS image file, the plugin calculates memory allocation sizes using signed 32-bit integers for width and height. If a crafted file sets both values to large values, their product exceeds 2^31 and overflows, resulting in an undersized heap-based buffer allocation. This integer overflow issue results in a heap-based buffer overflow when cfitsio subsequently writes a full row of pixels in the buffer, causing memory corruption, potentially leading to arbitrary code execution or a denial of service.
CVE-2026-68580 1 Freerdp 1 Freerdp 2026-08-05 7.5 High
FreeRDP before 3.29.0 contains integer overflow vulnerabilities in the audio input redirection channel (audin) across ALSA, sndio, WinMM, and OpenSL ES backends that fail to validate the FramesPerPacket parameter from RDP servers. Attackers can supply a malicious FramesPerPacket value causing allocation size wraparound, resulting in heap-based buffer overflow on ALSA or denial of service on all platforms.
CVE-2024-53111 1 Linux 1 Linux Kernel 2026-08-05 7.1 High
In the Linux kernel, the following vulnerability has been resolved: mm/mremap: fix address wraparound in move_page_tables() On 32-bit platforms, it is possible for the expression `len + old_addr < old_end` to be false-positive if `len + old_addr` wraps around. `old_addr` is the cursor in the old range up to which page table entries have been moved; so if the operation succeeded, `old_addr` is the *end* of the old region, and adding `len` to it can wrap. The overflow causes mremap() to mistakenly believe that PTEs have been copied; the consequence is that mremap() bails out, but doesn't move the PTEs back before the new VMA is unmapped, causing anonymous pages in the region to be lost. So basically if userspace tries to mremap() a private-anon region and hits this bug, mremap() will return an error and the private-anon region's contents appear to have been zeroed. The idea of this check is that `old_end - len` is the original start address, and writing the check that way also makes it easier to read; so fix the check by rearranging the comparison accordingly. (An alternate fix would be to refactor this function by introducing an "orig_old_start" variable or such.) Tested in a VM with a 32-bit X86 kernel; without the patch: ``` user@horn:~/big_mremap$ cat test.c #define _GNU_SOURCE #include <stdlib.h> #include <stdio.h> #include <err.h> #include <sys/mman.h> #define ADDR1 ((void*)0x60000000) #define ADDR2 ((void*)0x10000000) #define SIZE 0x50000000uL int main(void) { unsigned char *p1 = mmap(ADDR1, SIZE, PROT_READ|PROT_WRITE, MAP_ANONYMOUS|MAP_PRIVATE|MAP_FIXED_NOREPLACE, -1, 0); if (p1 == MAP_FAILED) err(1, "mmap 1"); unsigned char *p2 = mmap(ADDR2, SIZE, PROT_NONE, MAP_ANONYMOUS|MAP_PRIVATE|MAP_FIXED_NOREPLACE, -1, 0); if (p2 == MAP_FAILED) err(1, "mmap 2"); *p1 = 0x41; printf("first char is 0x%02hhx\n", *p1); unsigned char *p3 = mremap(p1, SIZE, SIZE, MREMAP_MAYMOVE|MREMAP_FIXED, p2); if (p3 == MAP_FAILED) { printf("mremap() failed; first char is 0x%02hhx\n", *p1); } else { printf("mremap() succeeded; first char is 0x%02hhx\n", *p3); } } user@horn:~/big_mremap$ gcc -static -o test test.c user@horn:~/big_mremap$ setarch -R ./test first char is 0x41 mremap() failed; first char is 0x00 ``` With the patch: ``` user@horn:~/big_mremap$ setarch -R ./test first char is 0x41 mremap() succeeded; first char is 0x41 ```
