CVE-2026-40014

An attacker that can send mail to a user can craft a message header that makes the IMAP THREAD command consume CPU disproportionate to the size of the message. When a mail client issues a THREAD command on the affected mailbox, this can cause degradation or denial of service for IMAP. Monitor...

CVE-2026-81334

darknet subscripts its layer array with an index taken from a configuration file without checking it against the array's length. The array is allocated in src-lib/darknetnetwork.cpp as xcallocnet.n, sizeofDarknet::Layer, sized to exactly the number of layer sections the file declares. The shortcu...

CVE-2026-80552

A flaw was found in the s390/vfioccw component of the Linux kernel. This vulnerability occurs because the system fails to properly validate index ranges for read/write operations on existing regions. This oversight could allow an attacker to perform out-of-bounds memory access, potentially leadin...

CVE-2026-47857 Reactor Core windowTimeout fair-backpressure stream hang due to 20-bit index wrap-around

In Reactor Core, applications that use the Flux.windowTimeout operator with fairBackpressure enabled are vulnerable to a Denial of Service DoS condition. Reactor Core 3.8.0 - 3.8.6 Reactor Core 3.5.0 - 3.7.19 Reactor Core 3.4.41 and earlier...

CVE-2026-47857

Reactor Core is affected by a Denial of Service condition in the Flux.windowTimeout operator when fairBackpressure is enabled. The root cause is a 20-bit index wrap-around that can cause the stream to hang, leading to an availability impact with no confidentiality or integrity loss. Affected vers...

CVE-2026-77652 Dia: dia: heap buffer overflow in wpg colormap parser via out-of-bounds palette index

A heap-based buffer overflow vulnerability exists in the Dia diagram editor WPG file format importer. In plug-ins/wpg/wpg-import.c, the WPG import renderer allocates a fixed palette with: ren-pPal = gnew0WPGColorRGB, 256; When handling a WPGCOLORMAP record, the parser reads a start index i16 and...

CVE-2026-77652

A heap-based buffer overflow in the Dia diagram editor's WPG file importer (plug-ins/wpg/wpg-import.c ) allows out-of-bounds writes into a fixed 256-entry color palette. The WPG_COLORMAP record handler validates the start index only against the WPG record size, not the palette capacity, so a craf...
