CVE-2026-55191 FreeRDP: Heap-buffer-overflow write in AVC444 YUV buffer allocation

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.27.0, FreeRDP clients that negotiate RDPGFX AVC444 with an H.264 decoder backend calculate the intermediate YUV444 allocation size in libfreerdp/codec/h264.c with 32-bit multiplication in avc444ensurebuffer. A malicious R...

CVE-2026-55191

FreeRDP clients prior to 3.27.0 are vulnerable to a heap-buffer-overflow write in the RDPGFX AVC444 codec path. In libfreerdp/codec/h264.c, the function avc444_ensure_buffer() computes the intermediate YUV444 buffer size using 32-bit multiplication (piDstStride[x] * padDstHeight). A malicious RDP...

CVE-2026-72369

A flaw was found in the Linux kernel's Minix filesystem. A local attacker can exploit this vulnerability by mounting a specially crafted Minix v3 image. This image can contain specific inode or zone counts that trigger an integer overflow during the calculation of bitmap block counts. The overflo...

CVE-2026-72367

A flaw was found in the Linux kernel's iomap subsystem. This vulnerability occurs due to an integer underflow when calculating iosize during concurrent file truncation operations. If a file is truncated while writeback is in progress, the iosize can wrap to a large value, leading to incorrect...

CVE-2026-74569

A flaw was found in the Linux kernel's netfilter Session Initiation Protocol SIP connection tracking module nfconntracksip. A remote attacker could send specially crafted SIP messages that cause an integer overflow during Network Address Translation NAT rewrite delta calculations. This overflow...

CVE-2026-75145

FFmpeg before commit b4c199c contains an incorrect integer narrowing conversion in the AV1 RTP packetizer libavformat/rtpencav1.c. The OBU size is cast to long before comparison against the remaining frame size. On targets where long is 32 bits, including 64-bit Windows, sufficiently large OBU si...

CVE-2026-72349

A flaw was found in the Linux kernel's netfilter component, specifically within the xtrateest module. This vulnerability occurs on network links operating at speeds of approximately 34 Gigabits per second Gbps or faster. Due to an integer truncation issue, the system incorrectly calculates the...

CVE-2026-70628

A flaw was found in FFmpeg. An attacker could exploit a signed integer overflow vulnerability within the DVB subtitle parser by providing a specially crafted WTV Windows Recorded TV Show file. This overflow can lead to a heap buffer overflow, enabling out-of-bounds memory writes. The consequence ...

EUVD-2026-62584

FFmpeg before commit 983dae9 contains an out-of-bounds read in the AV1 RTP packetizer libavformat/rtpencav1.c. The keyframe detection loop that searches for a sequence header OBU advanced its pointer and remaining-size counter by the encoded header length plus the OBU payload size without first...

CVE-2026-75147

FFmpeg versions before commit 983dae9 have an out-of-bounds read in the AV1 RTP packetizer (libavformat/rtpenc_av1.c). A crafted OBU size causes the remaining-size counter to wrap, letting the keyframe-detection loop dereference a pointer past the packet buffer. CVSS 3.1 scores 7.1 (HIGH). No in-...
