CVE-2024-42312

sysctl: always initialize i_uid/i_gid

State: Published
Severity: Not scored
Published: Aug 17, 2024
Updated: Oct 15, 2026
Reserved: Jul 30, 2024

Description

In the Linux kernel, the following vulnerability has been resolved:

sysctl: always initialize i_uid/i_gid

Always initialize i_uid/i_gid inside the sysfs core so set_ownership() can safely skip setting them.

Commit 5ec27ec735ba ("fs/proc/proc_sysctl.c: fix the default values of i_uid/i_gid on /proc/sys inodes.") added defaults for i_uid/i_gid when set_ownership() was not implemented. It also missed adjusting net_ctl_set_ownership() to use the same default values in case the computation of a better value failed.
