CVE-2026-64005
HIGH
7.8
CVSS 3.1
Description
In the Linux kernel, the following vulnerability has been resolved:
net/smc: Do not re-initialize smc hashtables
INIT_HLIST_HEAD(&smc_v*_hashinfo.ht) are called after smc_nl_init(),
proto_register() and sock_register(). This can lead to smc_v*_hashinfo.ht
being reset even though hash entries already exist and are being used,
possibly resulting in a corrupted list.
Remove unnecessary and dangerous re-initialisation of smc_v*_hashinfo.ht in
smc_init(); it is implicitly initialised to zero anyhow. Add
HLIST_HEAD_INIT to the definitions for clarity.
