CVE-2026-116741 is a medium-severity vulnerability rated 6.5/10 on the CVSS scale. Speex (libspeex) through 1.2.1 contains an out-of-bounds write vulnerability in speex_bits_read_whole_bytes() in libspeex/bits.c that mishandles length truncation for non-owned SpeexBits buffers. Attackers can stream crafted Speex data into buffers set up with speex_bits_init_buffer() or speex_bits_set_bit_buffer() to corrupt heap or stack memory and crash applications.. EPSS estimates a 0.41% chance of exploitation in the next 30 days.
