Use-after-free in Linux kernel - CVE-2026-23458

Published: April 6, 2026


Vulnerability identifier: #VU124913
CSH Severity: Low
CVSS v4: 6.8 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]
CVE-ID: CVE-2026-23458
CWE-ID: CWE-416
Exploitation vector: Local access
Exploit availability: No public exploit available

Vulnerability details

The vulnerability allows a local user to cause a denial of service.

The vulnerability exists due to use-after-free in ctnetlink_dump_exp_ct() and ctnetlink_exp_ct_dump_table() when handling multi-round netlink dump requests. A local user can trigger a netlink dump that spans multiple recvmsg() calls to cause a denial of service.

The issue occurs because a conntrack pointer stored in callback data is dereferenced after its reference is dropped, and the second dump round can access the freed object via nfct_help(ct). The proof of concept shows a slab-use-after-free read detected by KASAN.
