CVE-2026-44636

A flaw was found in libsixel. A signed integer overflow in sixelencodehighcolor's allocation size calculation can lead to a heap buffer overflow. The public sixelencode entry point validates only that width and height are greater than zero, with no upper bound. width and height are multiplied as...

EUVD-2026-30789

NetBSD prior to commit ec8451e contains a signed integer overflow vulnerability in the cryptodevop function in sys/opencrypto/cryptodev.c where the local variable iovlen is declared as a signed int but assigned from an unsigned cop-dstlen value, causing undefined behavior when cop-dstlen exceeds...

libsixel is a SIXEL encoder/decoder implementation derived from kmiya's sixel. From to 1.8.7-r1, signed integer overflow in sixelencodehighcolor's allocation size calculation can lead to a heap buffer overflow. The public sixelencode entry point validates only that width and height are greater th...

SUSE CVE-2026-31774

In the Linux kernel, the following vulnerability has been resolved: iouring/net: fix slab-out-of-bounds read in iobundlenbufs sqe-len is u32 but gets stored into sr-len which is int. When userspace passes sqe-len values exceeding INTMAX e.g. 0xFFFFFFFF, sr-len overflows to a negative value. This...

rdiscount has an Out-of-bounds Read

Summary A signed length truncation bug causes an out-of-bounds read in the default Markdown parse path. Inputs larger than INTMAX are truncated to a signed int before entering the native parser, allowing the parser to read past the end of the supplied buffer and crash the process Details In both...
