GNOME

Attackers may exploit SUID/SGID binaries like pkexec, su, or sudo on Linux systems to execute commands with elevated privileges, by identifying instances where a process runs with root privileges (user ID 0 or group ID 0) while the real user or group ID is non-root, allowing a low-privilege foothold to gain full system control.

A remote denial of service vulnerability, CVE-2026-15713, exists in the soupcache component of the Libsoup library due to a memory leak that leads to HTTP/2 frame window exhaustion, potentially causing application crashes or unresponsiveness.

An integer overflow vulnerability (CVE-2026-58384) exists in GIMP's PSD parser within the `read_RLE_channel()` function, leading to undersized heap allocations that can cause subsequent heap memory corruption, potentially resulting in denial of service or arbitrary code execution.

A high-severity off-by-one error, CVE-2026-58380, in GIMP's PNM file format parser (specifically the `pnmscanner_gettoken()` function) allows an attacker to corrupt memory by crafting a malicious PNM file, potentially leading to denial of service or arbitrary code execution when the file is opened.

This brief details how attackers may leverage the `systemd-run` utility on Linux systems for defense evasion and execution by running commands as detached, transient services or scopes to obscure their activities and parent-child process chains.

A heap buffer overflow vulnerability (CVE-2026-58379) in GIMP's Paint Shop Pro (PSP) file format parser allows a remote attacker to achieve arbitrary code execution or cause a denial of service (DoS) by tricking a user into opening a specially crafted PSP image file, exploiting incorrect buffer size calculations when processing low bit-depth images.
