CVE-2026-128987Dbus: infinite cpu-spin loop in libdbus socket transport when epipe is received during write operations

Red Hat Red Hat Enterprise Linux 10 Veröffentlicht: 2026-11-14 00:06 (vor 1 Stunde)

Beschreibung

A flaw was found in dbus. A local attacker can exploit this vulnerability by connecting to an affected service, requesting a response, and stopping socket reads while keeping the connection open. Because the socket transport handles broken pipe write errors as retryable, the application enters a continuous retry loop. This can lead to excessive CPU consumption, resulting in a denial of service (DoS) for the target process.

Abrt: abrt: abrt-server trusts client-supplied pid= allowing unprivileged read of other processes' /proc environ

Red Hat Red Hat Enterprise Linux 6; Red Hat Red Hat Enterprise Linux 7; Red Hat Red Hat Enterprise Linux 8

A flaw was found in abrt. abrt-server trusts a client-supplied PID when creating problem dumps over abrt.socket and, running as root, copies that process's /proc data (including environ) into a dump directory owned by the connecting unprivileged user. This al…

A flaw was found in abrt. The completeness check introduced to mitigate CVE-2026-54228 and CVE-2026-54229 only verifies that a dump directory contains a "count" element, which an unprivileged user can create. This allows a local attacker to bypass the guard a…
