Bug ID: 28587
Summary: Missing signal number check in pthread_kill if no
signal is sent
Product: glibc
Version: 2.34
Status: NEW
Severity: normal
Priority: P2
Component: nptl
Assignee: unassigned at sourceware dot org
Reporter: fweimer at redhat dot com
CC: drepper.fsp at gmail dot com
Target Milestone: ---
Commit a8ac8c4725ddb1119764126a8674a04c9dd5aea8 ("nptl: Fix race between
pthread_kill and thread exit (bug 12889)") removed all error checking when the
signal is not sent because the kernel-side thread has already exited (or is
about to). This is not correct, we still need to validate the signal number.
