What to Know

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. (NVD)

What to Do

Monitor Linux's web page for any future patch releases.
