NVD Description

Note: Versions mentioned in the description apply only to the upstream ocfs2-kmp-default package and not the ocfs2-kmp-default package as distributed by SLES. See How to fix? for SLES:15.5 relevant fixed versions and status.

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

ipv4: free net->ipv4.sysctl_local_reserved_ports after unregister_net_sysctl_table()

ipv4_sysctl_exit_net() is currently freeing net->ipv4.sysctl_local_reserved_ports too soon.

Only after unregister_net_sysctl_table() we can be sure no threads can possibly use the sysctls, including /proc/sys/net/ipv4/ip_local_reserved_ports.
