Severity ?
7.8 (High) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
Summary
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.

the race by concurrently tearing down a network namespace while hammering the sysctl or triggering socket port selection in that namespace.\\nPR:L - An unprivileged local user can reach this via user namespaces (CAP_SYS_ADMIN within the user_ns for CLONE_NEWNET) and world-writable sysctl access (mode 0644) during namespace destruction.\\nUI:N - No victim interaction is required beyond the attacker\u0027s own concurrent namespace teardown and sysctl or socket activity.\\nS:U - The UAF corrupts kernel heap memory within the same kernel security domain; it is standard local kernel memory corruption, not a VM/hypervisor boundary escape.\\nC:H - Freed 8 KiB bitmap memory remains reachable via sysctl reads (find_next_bit) and inet_is_local_reserved_port() (test_bit), enabling heap information disclosure through a use-after-free.\\nI:H - Sysctl writes via proc_do_large_bitmap perform bitmap_copy/bitmap_or into the freed allocation, providing a heap write primitive exploitable for control-flow hijacking.\\nA:H - Concurrent access to the freed bitmap can cause kernel oops/panic from invalid memory access, and UAF exploitation inherently threatens kernel availability.\"}]}],
