Descripción técnica

A flaw was found in BusyBox. The volume identification component fails to properly validate cluster parameters when analyzing specially formatted FAT filesystems. An attacker able to present a crafted storage device or disk image can trigger a divide-by-zero condition when partition scanning utilities inspect the volume. This issue causes the probing utilities to crash unexpectedly, resulting in a Denial of Service (DoS) that can disrupt device discovery and system boot operations.

——0A flaw was found in BusyBox. When processing filesystem metadata, the volume identification component does not properly validate header values in HFS+ filesystems. An attacker able to attach a storage device or supply a specially crafted filesystem image can trigger an application crash, resulting in a Denial of Service (DoS) and preventing device resolution.2d CVE-2026-1143735.5 MED

——5Photoshop Desktop is affected by a Divide By Zero vulnerability that could result in an application denial-of-service. An attacker could exploit this vulnerability to crash the application, leading to a denial-of-service condition. Exploitation of this issue requires user interaction in that a victim must open a malicious file.2d CVE-2026-1098026.5 MED

——7SAP NetWeaver Application Server for ABAP does not properly validate certain input values. An authenticated user could send specially crafted requests to trigger an error in internal processing. This could crash the affected work process and make the system unavailable. This results in a high impact on availability with no impact on confidentiality and integrity.2d CVE-2026-1252584.7 MED

——1FFmpeg through 9.0.2 contains a division by zero vulnerability in dovi_configure_ext() in libavcodec/dovi_rpuenc.c that allows attackers to crash the process via an unvalidated frame rate denominator. Attackers can supply a crafted HEVC or AV1 input with a nonzero frame rate numerator and zero denominator to the dovi_rpu bitstream filter or libx265, libaom, or libsvtav1 encoders, causing denial of service.2d CVE-2026-1252545.5 MED

——2FFmpeg through 9.0.2 contains a division by zero vulnerability in the VVC decoder because ff_vvc_slice_rpl() fails to validate num_ref_idx_active against built reference list entries. Attackers can supply a crafted VVC bitstream whose excess reference indices yield a zero POC difference in ff_vvc_mv_scale(), crashing the decoding process.2d CVE-2026-1252325.5 MED

——2FFmpeg through 9.0.2 contains a division by zero vulnerability in estimate_motion_b() in libavcodec/motion_est.c, caused by frame timestamp distances truncated to 16 bits. Attackers can supply input with timestamp gaps that are multiples of 65536, crashing MPEG-4 Part 2 or MPEG-1/2 B-frame encoding with SIGFPE.2d
