FKIE_CVE-2024-42312
Vulnerability from fkie_nvd - Published: 2024-08-17 09:15 - Updated: 2026-06-17 07:49
Severity
Summary
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.
