Summary
tls: always refresh the queue when reading sock
Details

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

tls: always refresh the queue when reading sock

After recent changes in net-next TCP compacts skbs much more aggressively. This unearthed a bug in TLS where we may try to operate on an old skb when checking if all skbs in the queue have matching decrypt state and geometry.

BUG: KASAN: slab-use-after-free in tls_strp_check_rcv+0x898/0x9a0 [tls]
(net/tls/tls_strp.c:436 net/tls/tls_strp.c:530 net/tls/tls_strp.c:544)
Read of size 4 at addr ffff888013085750 by task tls/13529

CPU: 2 UID: 0 PID: 13529 Comm: tls Not tainted 6.16.0-rc5-virtme
Call Trace:
 kasan_report+0xca/0x100
 tls_strp_check_rcv+0x898/0x9a0 [tls]
 tls_rx_rec_wait+0x2c9/0x8d0 [tls]
 tls_sw_recvmsg+0x40f/0x1aa0 [tls]
 inet_recvmsg+0x1c3/0x1f0

Always reload the queue, fast path is to have the record in the queue when we wake, anyway (IOW the path going down "if !strp->stm.full_len").
