AlmaLinux 9.2 [TuxCare] Security Update: flatpak / flatpak-devel / flatpak-libs / flatpak-selinux / etc Multiple Vulnerabilities (ALMALINUX9.2:CLSA-2026:1794225303)

high Nessus Plugin ID 377727

Synopsis

The AlmaLinux host is missing one or more security updates.

Description

The AlmaLinux 9.2 host has packages installed that are affected by multiple vulnerabilities as referenced in the TuxCare ALMALINUX9.2:CLSA-2026:1794225303 advisory.

 - A path traversal vulnerability in Flatpak's handling of the export/bin directory during app deployment allows a malicious Flatpak app to cause deletion of attacker-chosen files outside the deployment directory when the app is installed or upgraded. In system-wide installations, the deletion is performed as root.
 (CVE-2026-97023)

 - A path traversal vulnerability in Flatpak's handling of the files/etc directory during app deployment allows a malicious Flatpak app to cause certain host system files (such as passwd, group, machine-id, or resolv.conf) to be emptied or replaced with a symlink when the app is installed or upgraded. In system- wide installations, the write is performed as root. (CVE-2026-97024)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected packages based on the guidance in TuxCare advisory ALMALINUX9.2:CLSA-2026:1794225303.
