Rocky Linux 9.6 [TuxCare] Security Update: cpp / cross-gcc-aarch64 / cross-gcc-c++-aarch64 / gcc / gcc-c++ / etc Multiple Vulnerabilities (ALMALINUX9.6:CLSA-2026:1793179951)

high Nessus Plugin ID 373063

Synopsis

The Rocky Linux host is missing one or more security updates.

Description

The Rocky Linux 9.6 host has packages installed that are affected by multiple vulnerabilities as referenced in the TuxCare ALMALINUX9.6:CLSA-2026:1793179951 advisory.

 - A flaw was found in GCC. When an application calls the erase_if function on a binary heap priority queue in libstdc++, the library reallocates storage but fails to update its internal entry pointer. An attacker capable of triggering this operation can exploit this use-after-free condition, leading to a Denial of Service (DoS) via an application crash or potential memory corruption. (CVE-2026-102010)

 - A flaw was found in libstdc++. An integer overflow can occur when processing large inputs to the aligned operator new in the C++ library. This vulnerability could lead to an undersized memory allocation, potentially causing memory corruption or application instability. (CVE-2026-95619)

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 ALMALINUX9.6:CLSA-2026:1793179951.
