CVE-2026-102010
Gcc-toolset-15-gcc: gcc: gcc-toolset-16: gcc: denial of service via use-after-free in binary heap erase_if
publishedCWE-825
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.

Fixes and workarounds
Workaround
Applications can mitigate this issue by avoiding calls to erase_if() on __gnu_pbds::priority_queue containers that use the binary_heap_tag backend. Where predicate-based removal is required, use an alternative container or a different heap backend in application code. Apart from applying a fixed package when one becomes available, no other mitigation is currently available.
