NVD Description
Note: Versions mentioned in the description apply only to the upstream glibc
package and not the glibc
package as distributed by Ubuntu
.
In the GNU C Library (aka glibc or libc6) through 2.29, the memcmp function for the x32 architecture can incorrectly return zero (indicating that the inputs are equal) because the RDX most significant bit is mishandled.
