| In the Linux kernel, the following vulnerability has been resolved:
net: stmmac: Fix accessing freed irq affinity_hint
In stmmac_request_irq_multi_msi(), a pointer to the stack variable
cpu_mask is passed to irq_set_affinity_hint(). This value is stored in
irq_desc->affinity_hint, but once stmmac_request_irq_multi_msi()
returns, the pointer becomes dangling.
The affinity_hint is exposed via procfs with S_IRUGO permissions,
allowing any unprivileged process to read it. Accessing this stale
pointer can lead to:
- a kernel oops or panic if the referenced memory has been released and
unmapped, or
- leakage of kernel data into userspace if the memory is re-used for
other purposes.
All platforms that use stmmac with PCI MSI (Intel, Loongson, etc) are
affected. |
| In the Linux kernel, the following vulnerability has been resolved:
bus: mhi: host: Fix race between unprepare and queue_buf
A client driver may use mhi_unprepare_from_transfer() to quiesce
incoming data during the client driver's tear down. The client driver
might also be processing data at the same time, resulting in a call to
mhi_queue_buf() which will invoke mhi_gen_tre(). If mhi_gen_tre() runs
after mhi_unprepare_from_transfer() has torn down the channel, a panic
will occur due to an invalid dereference leading to a page fault.
This occurs because mhi_gen_tre() does not verify the channel state
after locking it. Fix this by having mhi_gen_tre() confirm the channel
state is valid, or return error to avoid accessing deinitialized data.

The following loop is located right above 'if' statement.
for (i = count-1; i >= 0; i--) {
/* is more than half of this entry in 2nd half of the block? */
if (size + map[i].size/2 > blocksize/2)
break;
size += map[i].size;
move++;
}
'i' in this case could go down to -1, in which case sum of active entries
wouldn't exceed half the block size, but previous behaviour would also do
split in half if sum would exceed at the very last block, which in case of
having too many long name files in a single block could lead to
out-of-bounds access and following use-after-free.

| In the Linux kernel, the following vulnerability has been resolved:
mptcp: fix NULL pointer in can_accept_new_subflow
When testing valkey benchmark tool with MPTCP, the kernel panics in
'mptcp_can_accept_new_subflow' because subflow_req->msk is NULL.
Call trace:
mptcp_can_accept_new_subflow (./net/mptcp/subflow.c:63 (discriminator 4)) (P)
subflow_syn_recv_sock (./net/mptcp/subflow.c:854)
tcp_check_req (./net/ipv4/tcp_minisocks.c:863)

ip_local_deliver (./net/ipv4/ip_input.c:254)
ip_rcv_finish (./net/ipv4/ip_input.c:449)
...
According to the debug log, the same req received two SYN-ACK in a very
short time, very likely because the client retransmits the syn ack due
to multiple reasons.
Even if the packets are transmitted with a relevant time interval, they
can be processed by the server on different CPUs concurrently). The
'subflow_req->msk' ownership is transferred to the subflow the first,
and there will be a risk of a null pointer dereference here.
This patch fixes this issue by moving the 'subflow_req->msk' under the
`own_req == true` conditional.
Note that the !msk check in subflow_hmac_valid() can be dropped, because
the same check already exists under the own_req mpj branch where the
code has been moved to. |
| In the Linux kernel, the following vulnerability has been resolved:
KVM: x86: Acquire SRCU in KVM_GET_MP_STATE to protect guest memory accesses
Acquire a lock on kvm->srcu when userspace is getting MP state to handle a
rather extreme edge case where "accepting" APIC events, i.e. processing
pending INIT or SIPI, can trigger accesses to guest memory. If the vCPU
is in L2 with INIT *and* a TRIPLE_FAULT request pending, then getting MP
state will trigger a nested VM-Exit by way of ->check_nested_events(), and
emuating the nested VM-Exit can access guest memory.
The splat was originally hit by syzkaller on a Google-internal kernel, and
reproduced on an upstream kernel by hacking the triple_fault_event_test
selftest to stuff a pending INIT, store an MSR on VM-Exit (to generate a
memory access on VMX), and do vcpu_mp_state_get() to trigger the scenario.

btrfs: don't clobber ret in btrfs_validate_super()
Commit 2a9bb78cfd36 ("btrfs: validate system chunk array at
btrfs_validate_super()") introduces a call to validate_sys_chunk_array()
in btrfs_validate_super(), which clobbers the value of ret set earlier.
This has the effect of negating the validity checks done earlier, making
it so btrfs could potentially try to mount invalid filesystems. |

netfilter: nfnetlink_queue: Initialize ctx to avoid memory allocation error
It is possible that ctx in nfqnl_build_packet_message() could be used

by nfqnl_get_sk_secctx().
This patch corrects this problem by initializing the lsmctx to a safe
value when it is declared.

Bluetooth: btnxpuart: Fix kernel panic during FW release
This fixes a kernel panic seen during release FW in a stress test
scenario where WLAN and BT FW download occurs simultaneously, and due to
a HW bug, chip sends out only 1 bootloader signatures.
When driver receives the bootloader signature, it enters FW download
mode, but since no consequtive bootloader signatures seen, FW file is
not requested.
After 60 seconds, when FW download times out, release_firmware causes a
kernel panic.

The problem can be reproduced using the following steps:
ip netns add foo
ip netns exec foo bash
cat /sys/class/infiniband/mlx4_0/hw_counters/*
The panic occurs because of casting the device pointer into an
ib_device pointer using container_of() in hw_stat_device_show() is
wrong and leads to a memory corruption.
However the real problem is that hw counters should never been exposed
outside of the non-init net namespace.
Fix this by saving the index of the corresponding attribute group
(it might be 1 or 2 depending on the presence of driver-specific
attributes) and zeroing the pointer to hw_counters group for compat
devices during the initialization.
With this fix applied hw_counters are not available in a non-init
net namespace:

| In the Linux kernel, the following vulnerability has been resolved:
RDMA/erdma: Prevent use-after-free in erdma_accept_newconn()
After the erdma_cep_put(new_cep) being called, new_cep will be freed,
and the following dereference will cause a UAF problem. Fix this issue. |
| In the Linux kernel, the following vulnerability has been resolved:
bpf: Fix array bounds error with may_goto
may_goto uses an additional 8 bytes on the stack, which causes the
interpreters[] array to go out of bounds when calculating index by
stack_size.
1. If a BPF program is rewritten, re-evaluate the stack size. For non-JIT
cases, reject loading directly.
2. For non-JIT cases, calculating interpreters[idx] may still cause
out-of-bounds array access, and just warn about it.
3. For jit_requested cases, the execution of bpf_func also needs to be
warned. So move the definition of function __bpf_prog_ret0_warn out of
the macro definition CONFIG_BPF_JIT_ALWAYS_ON. |
| In the Linux kernel, the following vulnerability has been resolved:
RDMA/mlx5: Fix mlx5_poll_one() cur_qp update flow
When cur_qp isn't NULL, in order to avoid fetching the QP from
the radix tree again we check if the next cqe QP is identical to
the one we already have.
The bug however is that we are checking if the QP is identical by
checking the QP number inside the CQE against the QP number inside the
mlx5_ib_qp, but that's wrong since the QP number from the CQE is from
FW so it should be matched against mlx5_core_qp which is our FW QP
number.
Otherwise we could use the wrong QP when handling a CQE which could
cause the kernel trace below.
This issue is mainly noticeable over QPs 0 & 1, since for now they are
the only QPs in our driver whereas the QP number inside mlx5_ib_qp
doesn't match the QP number inside mlx5_core_qp.

| In the Linux kernel, the following vulnerability has been resolved:
fs/ntfs3: Fix a couple integer overflows on 32bit systems
On 32bit systems the "off + sizeof(struct NTFS_DE)" addition can
have an integer wrapping issue. Fix it by using size_add(). |
| In the Linux kernel, the following vulnerability has been resolved:
fs/ntfs3: Prevent integer overflow in hdr_first_de()
The "de_off" and "used" variables come from the disk so they both need to
check. The problem is that on 32bit systems if they're both greater than
UINT_MAX - 16 then the check does work as intended because of an integer
overflow. |
| In the Linux kernel, the following vulnerability has been resolved:
ocfs2: validate l_tree_depth to avoid out-of-bounds access
The l_tree_depth field is 16-bit (__le16), but the actual maximum depth is
limited to OCFS2_MAX_PATH_DEPTH.
Add a check to prevent out-of-bounds access if l_tree_depth has an invalid
value, which may occur when reading from a corrupted mounted disk [1]. |
| In the Linux kernel, the following vulnerability has been resolved:
ksmbd: fix r_count dec/increment mismatch
r_count is only increased when there is an oplock break wait,
so r_count inc/decrement are not paired. This can cause r_count
to become negative, which can lead to a problem where the ksmbd
thread does not terminate. |
