Sudo broken with glibc 2.39 (on Raspberry Pi 0W)

Since commit package/glibc: bump to 2.39 (introduced in Buildroot 2024.05) I can no longer use sudo command on Raspberry Pi 0w. It does not accept my password:

$ sudo ls
Password: 
Sorry, try again.

All I have done are few modifications to upstream raspberrypi0w_defconfig:

  1. Enabled sudo BR2_PACKAGE_SUDO=y
  2. Added users table BR2_ROOTFS_USERS_TABLES="users-table" 
$ cat users-table 
user -1 users -1 =user /home/user /bin/sh
  1. Added sudoers BR2_ROOTFS_OVERLAY="rootfs-overlay" 
$ cat rootfs-overlay/etc/sudoers 
user   ALL=(ALL) ALL

And since my Raspberry has broken serial line, I added small init script to run getty over USB (configfs usb gadget) instead of uart and set BR2_TARGET_GENERIC_GETTY_PORT="ttyGS0"

Happens also on current master. Reverting mentioned commit above helps.
