CVE-2026-49416
The CVE-2026-49416 issue affects FreeBSD vt(4) CONS_HISTORY: the ioctl handler validates the requested history size, but large values trigger an integer overflow in the buffer size calculation, causing a smaller heap allocation and an out-of-bounds write on initialization. This can enable an unpr...
EUVD-2026-39960
The CONSHISTORY ioctl handler did not adequately validate the requested history size. A large value caused an integer overflow in the buffer size calculation, resulting in a heap allocation smaller than expected. Subsequent initialization of the buffer wrote beyond the end of the allocation. An...
CVE-2026-49416 Integer overflow in vt(4) CONS_HISTORY ioctl
The CONSHISTORY ioctl handler did not adequately validate the requested history size. A large value caused an integer overflow in the buffer size calculation, resulting in a heap allocation smaller than expected. Subsequent initialization of the buffer wrote beyond the end of the allocation. An...
CVE-2026-49417
Second, the audio buffer backing a mapping could be freed when the device was closed even though the mapping remained valid. The freed memory could then be reused elsewhere while still accessible through the stale mapping. The /dev/dsp device nodes are world-accessible by default. On a system wit...
CVE-2026-45258 Multiple vulnerabilities in the sound(4) mmap path
dspmmapsingle validated the requested mapping by checking the sum of the user-supplied offset and length against the buffer size. This addition could overflow, so that a large offset and length wrapped around and passed the check. The offset was then narrowed from 64 to 32 bits when converted to ...

CVE-2026-45258
The CVE-2026-45258 issue affects FreeBSD sound(4) mmap support. dsp_mmap_single() overflows when validating the requested mapping because offset+length can wrap the size check, and the offset is reduced from 64 to 32 bits for the buffer address, allowing a mapping that extends past the audio buff...
CVE-2026-49417
CVE-2026-49417 is part of two memory-safety issues in FreeBSD’s sound(4) mmap path. The advisories describe: (1) dsp_mmap_single() could overflow when validating a requested mapping, allowing a mapping to extend past the audio buffer into kernel memory (CVE-2026-45258), and (2) the audio buffer b...
