| Fixed In Version: | glibc-2.28-189.4.el8_6 | Doc Type: | Bug Fix |
| Doc Text: |
Cause: The POWER9 variant of the strncpy function uses the wrong register for writing NUL padding.
Consequence: Uninitialized register content is written to the output buffer.
Fix: The correct register is now used as the source for the NUL bytes.
Result: The tail end of the output buffer is now correctly overwritten with NUL bytes.
