——0libpcap BPF interpreter for the 'div #k' and 'mod #k' ALU instructions does not check whether the immediate value is zero. In particular uncommon use cases a crafted filter program can cause a division by zero.3d CVE-2026-383456.5 MED

——5A Division-by-Zero vulnerability in the ff_sws_init_single_context function (/libswscale/utils.c) of FFmpeg N-122528-gdd2976b9e1 allows attackers to cause a Denial of Service (DoS) via a crafted input.6d CVE-2026-754666.5 MED

——3libjpeg-turbo 3.2.0 contains an integer division-by-zero vulnerability in the PNG loader. When processing a valid indexed-color PNG image with a non-gray palette through tj3LoadImage12() or tj3LoadImage16() using the default pixel format, the application may trigger a division-by-zero in alloc_sarray(), causing a SIGFPE and denial of service.12d CVE-2026-718326.2 MED

——1Aria2 version 1.37.0 and below is affected by a Divide By Zero issue in src/bittorrent_helper.cc, which allows a remote malicious user to cause a Denial of Service11d CVE-2026-168974.4 MED

——0IBM AIX 7.2, and 7.3 and IBM PowerVM VIOS 4.1 could allow a local attacker to cause a denial of service due to an out-of-bounds write.19d CVE-2026-631176.5 MED

——10FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.28.0, an authenticated RDP client can advertise DVI ADPCM with nBlockAlign equal to 8 and nChannels equal to 2 to make the `bs` calculation in rdpsnd_server_select_format in channels/rdpsnd/server/rdpsnd_main.c equal zero. The subsequent out_frames modulo `bs` operation raises SIGFPE and terminates the server-side rdpsnd channel process. This vulnerability fixed in 3.28.0.20d
