What is CVE-2026-102010?

A flaw exists in the GCC compiler where the erase_if function in the libstdc++ library does not properly handle the reallocation of storage within a binary heap priority queue. This oversight results in a use-after-free condition, which may allow an attacker with the capability to invoke the erase_if function to exploit this vulnerability. The consequences can include unauthorized application crashes and potential memory corruption, posing significant risks to overall system stability and security.
