CVE-2025-62594 1 Imagemagick 1 Imagemagick 2025-11-03 N/A 4.7 MEDIUM
ImageMagick is a software suite to create, edit, compose, or convert bitmap images. ImageMagick versions prior to 7.1.2-8 are vulnerable to denial-of-service due to unsigned integer underflow and division-by-zero in the CLAHEImage function. When tile width or height is zero, unsigned underflow occurs in pointer arithmetic, leading to out-of-bounds memory access, and division-by-zero causes immediate crashes. This issue has been patched in version 7.1.2-8.
CVE-2024-57823 1 Librdf 1 Raptor Rdf Syntax Library 2025-11-03 N/A 9.3 CRITICAL
In Raptor RDF Syntax Library through 2.0.16, there is an integer underflow when normalizing a URI with the turtle parser in raptor_uri_normalize_path().
CVE-2025-62495 1 Quickjs Project 1 Quickjs 2025-10-29 N/A 8.8 HIGH
An integer overflow vulnerability exists in the QuickJS regular expression engine (libregexp) due to an inconsistent representation of the bytecode buffer size. * The regular expression bytecode is stored in a DynBuf structure, which correctly uses a $\text{size}\_\text{t}$ (an unsigned type, typically 64-bit) for its size member. * However, several functions, such as re_emit_op_u32 and other internal parsing routines, incorrectly cast or store this DynBuf $\text{size}\_\text{t}$ value into a signed int (typically 32-bit). * When a large or complex regular expression (such as those generated by a recursive pattern in a Proof-of-Concept) causes the bytecode size to exceed $2^{31}$ bytes (the maximum positive value for a signed 32-bit integer), the size value wraps around, resulting in a negative integer when stored in the int variable (Integer Overflow). * This negative value is subsequently used in offset calculations. For example, within functions like re_parse_disjunction, the negative size is used to compute an offset (pos) for patching a jump instruction. * This negative offset is then incorrectly added to the buffer pointer (s->byte\_code.buf + pos), leading to an out-of-bounds write on the first line of the snippet below: put_u32(s->byte_code.buf + pos, len);
CVE-2022-39293 1 Eclipse 1 Threadx Usbx 2025-10-27 N/A 8.6 HIGH
Azure RTOS USBX is a high-performance USB host, device, and on-the-go (OTG) embedded stack, that is fully integrated with Azure RTOS ThreadX. The case is, in [_ux_host_class_pima_read](https://github.com/azure-rtos/usbx/blob/master/common/usbx_host_classes/src/ux_host_class_pima_read.c), there is data length from device response, returned in the very first packet, and read by [L165 code](https://github.com/azure-rtos/usbx/blob/082fd9db09a3669eca3358f10b8837a5c1635c0b/common/usbx_host_classes/src/ux_host_class_pima_read.c#L165), as header_length. Then in [L178 code](https://github.com/azure-rtos/usbx/blob/082fd9db09a3669eca3358f10b8837a5c1635c0b/common/usbx_host_classes/src/ux_host_class_pima_read.c#L178), there is a “if” branch, which check the expression of “(header_length - UX_HOST_CLASS_PIMA_DATA_HEADER_SIZE) > data_length” where if header_length is smaller than UX_HOST_CLASS_PIMA_DATA_HEADER_SIZE, calculation could overflow and then [L182 code](https://github.com/azure-rtos/usbx/blob/082fd9db09a3669eca3358f10b8837a5c1635c0b/common/usbx_host_classes/src/ux_host_class_pima_read.c#L182) the calculation of data_length is also overflow, this way the later [while loop start from L192](https://github.com/azure-rtos/usbx/blob/082fd9db09a3669eca3358f10b8837a5c1635c0b/common/usbx_host_classes/src/ux_host_class_pima_read.c#L192) can move data_pointer to unexpected address and cause write buffer overflow. The fix has been included in USBX release [6.1.12](https://github.com/azure-rtos/usbx/releases/tag/v6.1.12_rel). The following can be used as a workaround: Add check of `header_length`: 1. It must be greater than `UX_HOST_CLASS_PIMA_DATA_HEADER_SIZE`. 1. It should be greater or equal to the current returned data length (`transfer_request -> ux_transfer_request_actual_length`).
CVE-2025-55096 1 Eclipse 1 Threadx Usbx 2025-10-23 N/A 6.1 MEDIUM
In USBX before 6.4.3, the USB support module for Eclipse Foundation ThreadX, there was a potential out of bound read issue in _ux_host_class_hid_report_descriptor_get()  when parsing a descriptor of an USB HID device.
CVE-2022-49650 1 Linux 1 Linux Kernel 2025-10-23 N/A 5.5 MEDIUM
In the Linux kernel, the following vulnerability has been resolved: dmaengine: qcom: bam_dma: fix runtime PM underflow Commit dbad41e7bb5f ("dmaengine: qcom: bam_dma: check if the runtime pm enabled") caused unbalanced pm_runtime_get/put() calls when the bam is controlled remotely. This commit reverts it and just enables pm_runtime in all cases, the clk_* functions already just nop when the clock is NULL. Also clean up a bit by removing unnecessary bamclk null checks.
CVE-2022-49199 1 Linux 1 Linux Kernel 2025-10-21 N/A 5.5 MEDIUM
In the Linux kernel, the following vulnerability has been resolved: RDMA/nldev: Prevent underflow in nldev_stat_set_counter_dynamic_doit() This code checks "index" for an upper bound but it does not check for negatives. Change the type to unsigned to prevent underflows.
CVE-2025-59242 1 Microsoft 16 Windows 10 1507, Windows 10 1607, Windows 10 1809 and 13 more 2025-10-17 N/A 7.8 HIGH

CVE-2022-49564 1 Linux 1 Linux Kernel 2025-10-01 N/A 5.5 MEDIUM
In the Linux kernel, the following vulnerability has been resolved: crypto: qat - add param check for DH Reject requests with a source buffer that is bigger than the size of the key. This is to prevent a possible integer underflow that might happen when copying the source scatterlist into a linear buffer.
CVE-2022-49563 1 Linux 1 Linux Kernel 2025-10-01 N/A 5.5 MEDIUM
In the Linux kernel, the following vulnerability has been resolved: crypto: qat - add param check for RSA Reject requests with a source buffer that is bigger than the size of the key. This is to prevent a possible integer underflow that might happen when copying the source scatterlist into a linear buffer.
CVE-2022-49208 1 Linux 1 Linux Kernel 2025-10-01 N/A 5.5 MEDIUM
In the Linux kernel, the following vulnerability has been resolved: RDMA/irdma: Prevent some integer underflows My static checker complains that: drivers/infiniband/hw/irdma/ctrl.c:3605 irdma_sc_ceq_init() warn: can subtract underflow 'info->dev->hmc_fpm_misc.max_ceqs'? It appears that "info->dev->hmc_fpm_misc.max_ceqs" comes from the firmware in irdma_sc_parse_fpm_query_buf() so, yes, there is a chance that it could be zero. Even if we trust the firmware, it's easy enough to change the condition just as a hardenning measure.
CVE-2020-11909 1 Treck 1 Tcp\/ip 2025-09-30 5.0 MEDIUM 5.3 MEDIUM
The Treck TCP/IP stack before 6.0.1.66 has an IPv4 Integer Underflow.
CVE-2022-48828 1 Linux 1 Linux Kernel 2025-09-25 N/A 5.5 MEDIUM
In the Linux kernel, the following vulnerability has been resolved: NFSD: Fix ia_size underflow iattr::ia_size is a loff_t, which is a signed 64-bit type. NFSv3 and NFSv4 both define file size as an unsigned 64-bit type. Thus there is a range of valid file size values an NFS client can send that is already larger than Linux can handle. Currently decode_fattr4() dumps a full u64 value into ia_size. If that value happens to be larger than S64_MAX, then ia_size underflows. I'm about to fix up the NFSv3 behavior as well, so let's catch the underflow in the common code path: nfsd_setattr().
CVE-2024-57843 1 Linux 1 Linux Kernel 2025-09-24 N/A 5.5 MEDIUM
In the Linux kernel, the following vulnerability has been resolved: virtio-net: fix overflow inside virtnet_rq_alloc When the frag just got a page, then may lead to regression on VM. Specially if the sysctl net.core.high_order_alloc_disable value is 1, then the frag always get a page when do refill. Which could see reliable crashes or scp failure (scp a file 100M in size to VM). The issue is that the virtnet_rq_dma takes up 16 bytes at the beginning of a new frag. When the frag size is larger than PAGE_SIZE, everything is fine. However, if the frag is only one page and the total size of the buffer and virtnet_rq_dma is larger than one page, an overflow may occur. The commit f9dac92ba908 ("virtio_ring: enable premapped mode whatever use_dma_api") introduced this problem. And we reverted some commits to fix this in last linux version. Now we try to enable it and fix this bug directly. Here, when the frag size is not enough, we reduce the buffer len to fix this problem.
