CVE-2026-46123 Bluetooth: virtio_bt: clamp rx length before skb_put

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: virtiobt: clamp rx length before skbput virtbtrxwork calls skbputskb, len where len comes directly from virtqueuegetbuf with no validation against the buffer we posted to the device. The RX skb is allocated in...

CVE-2026-46123

Summary: CVE-2026-46123 affects the Linux kernel Bluetooth virtio_bt driver. The issue arises when virtbt_rx_work() skb_put(skb, len) uses an unvalidated len sourced from virtqueue_get_buf(), with the device exposing a 1000-byte RX buffer. Since alloc_skb() tailroom can exceed 1000, a malicious/b...

CVE-2026-46064

CVE-2026-46064 affects the Linux kernel’s ibmasm_send_i2o_message, where the copy size is derived from user-controlled dot_command_header fields and not validated against allocation size. This can let an attacker perform a heap over-read by memcpy_toio(), reaching up to ~65 KB beyond the allocate...

EUVD-2026-31830

FreeRDP before 3.26.0 contains a heap-buffer-overflow vulnerability in gdiCacheToSurface that allows remote attackers to write out-of-bounds heap memory. The vulnerability occurs because rectangle validation clamps coordinates to UINT16MAX but performs copy operations using unclamped cache entry...

CVE-2026-43904 OpenImageIO: Softimage PIC RLE decoder heap buffer overflow — longCount not clamped to image width

OpenImageIO is a toolset for reading, writing, and manipulating image files of any image file format relevant to VFX / animation. Prior to 3.0.18.0 and 3.1.13.0, softimageinput.cpp:469 mixed RLE and :345 pure RLE do not clamp the run length to remaining scanline width before writing pixels. The r...

CVE-2026-43904

OpenImageIO prior to 3.0.18.0 and 3.1.13.0 has a heap overflow in the RLE decoder for the Softimage PIC path (softimageinput.cpp:469 and :345) because run length is not clamped to scanline width before writing pixels. The raw packet path clamps correctly, but the RLE paths do not, allowing a craf...
