Gcc-toolset-15-gcc: gcc: gcc-toolset-16: gcc: denial of service via use-after-free in binary heap erase_if

Type: advisorySource: Official CVE List1 source record

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.
