Title
RDMA/mana: Remove user triggerable WARN_ON() in mana_ib_create_qp_rss()
Summary
In the Linux kernel, the following vulnerability has been resolved:
RDMA/mana: Remove user triggerable WARN_ON() in mana_ib_create_qp_rss()
Sashiko points out that the user can specify WQs sharing the same CQ as a
part of the uAPI and this will trigger the WARN_ON() then go on to corrupt
the kernel.
Just reject it outright and fail the QP creation.

Title
Bluetooth: l2cap: Add missing chan lock in l2cap_ecred_reconf_rsp
Summary
In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: l2cap: Add missing chan lock in l2cap_ecred_reconf_rsp
l2cap_ecred_reconf_rsp() calls l2cap_chan_del() without holding
l2cap_chan_lock(). Every other l2cap_chan_del() caller in the file
acquires the lock first. A remote BLE device can send a crafted
L2CAP ECRED reconfiguration response to corrupt the channel list
while another thread is iterating it.
Add l2cap_chan_hold() and l2cap_chan_lock() before l2cap_chan_del(),
and l2cap_chan_unlock() and l2cap_chan_put() after, matching the
pattern used in l2cap_ecred_conn_rsp() and l2cap_conn_del().

The race is between attacker-timed peer signaling and normal channel/socket activity, with no rare external condition required.\nPR:N - The receive path performs no OS privilege or capability check on the remote peer before dispatching the L2CAP_ECRED_RECONF_RSP. A nearby BLE device can send the crafted response as protocol input without local credentials.\nUI:N - In a plausible phone, embedded, or IoT deployment, an ECRED-using service can maintain/reconfigure BLE channels without a victim performing an exploit-time action. The attacker only needs to send the malicious BLE response at the protocol level.\nS:U - The corruption occurs inside the kernel Bluetooth/L2CAP subsystem and impacts the same kernel security authority. It is not a VM escape or other cross-scope boundary bypass.\nC:H - The missing channel lock permits unsynchronized channel deletion and list/lifetime corruption in kernel memory. As memory corruption, it is defensible to treat it as capable of yielding kernel information disclosure primitives.\nI:H - Concurrent `l2cap_chan_del()` without the required channel lock can corrupt kernel list/object state and potentially be shaped beyond a simple disconnect. Under the required conservative scoring rule, this kernel memory corruption supports high integrity impact.\nA:H - At minimum, corrupted L2CAP channel list/lifetime state can cause kernel oops, panic, or hang. The vulnerable code can be reached repeatedly by a malicious nearby BLE peer."
