Title
pid: Add a judgment for ns null in pid_nr_ns
Summary
In the Linux kernel, the following vulnerability has been resolved:
pid: Add a judgment for ns null in pid_nr_ns
__task_pid_nr_ns
ns = task_active_pid_ns(current);
pid_nr_ns(rcu_dereference(*task_pid_ptr(task, type)), ns);
if (pid && ns->level <= pid->level) {
Sometimes null is returned for task_active_pid_ns. Then it will trigger kernel panic in pid_nr_ns.
For example:
Unable to handle kernel NULL pointer dereference at virtual address 0000000000000058

Title
bpf: Fix metadata_dst leak __bpf_redirect_neigh_v{4,6}
Summary
In the Linux kernel, the following vulnerability has been resolved:
bpf: Fix metadata_dst leak __bpf_redirect_neigh_v{4,6}
Cilium has a BPF egress gateway feature which forces outgoing K8s Pod
traffic to pass through dedicated egress gateways which then SNAT the
traffic in order to interact with stable IPs outside the cluster.
The traffic is directed to the gateway via vxlan tunnel in collect md
mode. A recent BPF change utilized the bpf_redirect_neigh() helper to
forward packets after the arrival and decap on vxlan, which turned out
over time that the kmalloc-256 slab usage in kernel was ever-increasing.
The issue was that vxlan allocates the metadata_dst object and attaches
it through a fake dst entry to the skb. The latter was never released
though given bpf_redirect_neigh() was merely setting the new dst entry
via skb_dst_set() without dropping an existing one first.

Title
ice: ice_adapter: release xa entry on adapter allocation failure
Summary
In the Linux kernel, the following vulnerability has been resolved:
ice: ice_adapter: release xa entry on adapter allocation failure
When ice_adapter_new() fails, the reserved XArray entry created by
xa_insert() is not released. This causes subsequent insertions at
the same index to return -EBUSY, potentially leading to
NULL pointer dereferences.
Reorder the operations as suggested by Przemek Kitszel:
1. Check if adapter already exists (xa_load)
2. Reserve the XArray slot (xa_reserve)
3. Allocate the adapter (ice_adapter_new)
4. Store the adapter (xa_store)
Severity

Title
tcp: Don't call reqsk_fastopen_remove() in tcp_conn_request().
Summary
In the Linux kernel, the following vulnerability has been resolved:
tcp: Don't call reqsk_fastopen_remove() in tcp_conn_request().
syzbot reported the splat below in tcp_conn_request(). [0]
If a listener is close()d while a TFO socket is being processed in
tcp_conn_request(), inet_csk_reqsk_queue_add() does not set reqsk->sk
and calls inet_child_forget(), which calls tcp_disconnect() for the
TFO socket.
After the cited commit, tcp_disconnect() calls reqsk_fastopen_remove(),
where reqsk_put() is called due to !reqsk->sk.
Then, reqsk_fastopen_remove() in tcp_conn_request() decrements the
last req->rsk_refcnt and frees reqsk, and __reqsk_free() at the
drop_and_free label causes the refcount underflow for the listener
and double-free of the reqsk.
Let's remove reqsk_fastopen_remove() in tcp_conn_request().
Note that other callers make sure tp->fastopen_rsk is not NULL.
[0]:
refcount_t: underflow; use-after-free.

Title
net/sctp: fix a null dereference in sctp_disposition sctp_sf_do_5_1D_ce()
Summary
In the Linux kernel, the following vulnerability has been resolved:
net/sctp: fix a null dereference in sctp_disposition sctp_sf_do_5_1D_ce()
If new_asoc->peer.adaptation_ind=0 and sctp_ulpevent_make_authkey=0
and sctp_ulpevent_make_authkey() returns 0, then the variable
ai_ev remains zero and the zero will be dereferenced
in the sctp_ulpevent_free() function.

Any host with a listening SCTP socket (telecom SIGTRAN/M3UA/Diameter signalling nodes are routinely inter-carrier and internet facing) is remotely reachable.\nAC:L - The attacker deterministically controls both selectable preconditions by simply omitting the Adaptation Layer Indication parameter (leaving `ai_ev` NULL) and omitting the SCTP-AUTH parameters (forcing the `sctp_ulpevent_make_authkey()` call), which are the default characteristics of a plain handshake. The only remaining factor is the GFP_ATOMIC allocation failing, which the attacker can influence by flooding the target with concurrent association attempts and traffic to exhaust atomic reserves \u2014 particularly effective on the memory-constrained embedded/telecom devices where SCTP is deployed.\nPR:N - SCTP association establishment is entirely unauthenticated; the attacker only needs to complete the standard INIT / INIT-ACK / COOKIE ECHO exchange against a listening socket, with the state cookie having been minted by the victim itself. No credentials, capabilities, or local account are involved anywhere along the path.\nUI:N - Exploitation requires nothing from any local user or administrator beyond the pre-existing condition that an SCTP service is listening. The attacker drives the entire handshake unilaterally.\nS:U - The NULL dereference faults inside the kernel handling the same network stack that received the packet; there is no crossing into another security authority such as a hypervisor, IOMMU, or sandbox boundary.\nC:N - The dereference is a read of `event-\u003emsg_flags` at a fixed low offset from NULL, which faults immediately; no data is returned to the attacker and no kernel memory contents are disclosed.\nI:N - The bug is a read fault on a NULL pointer with no write, no out-of-bounds access, and no object lifetime confusion, so no kernel data is modified and no control-flow hijack primitive is produced.\nA:H - The dereference occurs in NET_RX softirq context, producing a fatal exception in interrupt \u2014 a kernel panic and complete loss of availability, or at minimum an oops that kills the softirq path (and an immediate panic on the `panic_on_oops` configurations common in embedded and telecom deployments). The attacker can repeat the attempt indefinitely across reboots."

Title
Revert "ipmi: fix msg stack when IPMI is disconnected"
Summary
In the Linux kernel, the following vulnerability has been resolved:
Revert "ipmi: fix msg stack when IPMI is disconnected"
This reverts commit c608966f3f9c2dca596967501d00753282b395fc.
This patch has a subtle bug that can cause the IPMI driver to go into an
infinite loop if the BMC misbehaves in a certain way. Apparently
certain BMCs do misbehave this way because several reports have come in
recently about this.
Severity
No CVSS data available.

Title
cpufreq: intel_pstate: Fix object lifecycle issue in update_qos_request()
Summary
In the Linux kernel, the following vulnerability has been resolved:
cpufreq: intel_pstate: Fix object lifecycle issue in update_qos_request()
The cpufreq_cpu_put() call in update_qos_request() takes place too early
because the latter subsequently calls freq_qos_update_request() that
indirectly accesses the policy object in question through the QoS request
object passed to it.
Fortunately, update_qos_request() is called under intel_pstate_driver_lock,
so this issue does not matter for changing the intel_pstate operation
mode, but it theoretically can cause a crash to occur on CPU device hot
removal (which currently can only happen in virt, but it is formally
supported nevertheless).
Address this issue by modifying update_qos_request() to drop the
reference to the policy later.
Severity

Title
fs: quota: create dedicated workqueue for quota_release_work
Summary
In the Linux kernel, the following vulnerability has been resolved:
fs: quota: create dedicated workqueue for quota_release_work
There is a kernel panic due to WARN_ONCE when panic_on_warn is set.
This issue occurs when writeback is triggered due to sync call for an
opened file(ie, writeback reason is WB_REASON_SYNC). When f2fs balance
is needed at sync path, flush for quota_release_work is triggered.
By default quota_release_work is queued to "events_unbound" queue which
does not have WQ_MEM_RECLAIM flag. During f2fs balance "writeback"
workqueue tries to flush quota_release_work causing kernel panic due to
MEM_RECLAIM flag mismatch errors.
This patch creates dedicated workqueue with WQ_MEM_RECLAIM flag
for work quota_release_work.
