389-ds-base: 389-ds-base: heap buffer overflow via SASL wrapped-record length lower-bound underflow in sasl_io_start_packet()

A heap buffer overflow flaw was found in the SASL I/O layer of 389 Directory Server 389-ds-base. In sasliostartpacket, the wrapped-record length read from the wire is validated only against an upper bound. A small wire length 0, 1, or 2 produces an encryptedbuffercount below the already-consumed...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: drm/sun4i: dsi: Prevent underflow when calculating packet sizes. Currently, the packet overhead is subtracted using unsigned arithmetic. With a short sync pulse, this could lead to an underflow, causing the value to wrap around t...

Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: drm/i915/selftests: fixed the subtraction overflow bug. On some machines, holeend can be small enough to cause subtraction overflow. On the other hand, addr + 2 minalignment can cause overflow in case of mock tests. This patch...

Linux Distros Unpatched Vulnerability : CVE-2026-89551

"The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - SUNRPC: xdrbuftrim: clamp buf-len to avoid underflow xdrbuftrim trims len bytes from the tail of an xdrbuf by walking the tail, pages, and head iovecs. Each...

CVE-2026-89551

CVE-2026-89551 is a CRITICAL (CVSS 9.8) integer underflow in the Linux kernel's SUNRPC subsystem. The xdr_buf_trim() function subtracts consumed bytes from buf->len without clamping, so when called from gss_krb5_unwrap_v2() with a small wire-derived buf->len while page-scale iov_lens are pr...

CVE-2026-68196

CVE-2026-68196 affects the Linux kernel wilc1000 Wi-Fi driver. A malformed association response can lead to an out-of-bounds read due to improper validation when computing trailing IE length (ies_len = buffer_len - sizeof(*res)) without verifying buffer_len against the fixed header. Short frames ...
