The malloc function in the GNU C Library (aka glibc or libc6) 2.26 could
return a memory block that is too small if an attempt is made to allocate
an object whose size is close to SIZE_MAX, potentially leading to a
subsequent heap overflow. This occurs because the per-thread cache (aka
tcache) feature enables a code path that lacks an integer overflow check.
