but I'll say it anyway: the enetc_tx_onestep_tstamp() work item runs in
process context, therefore with softirqs enabled (i.o.w., it can be
interrupted by a softirq). If we hold the netif_tx_lock() when there is
an interrupt, and the NET_TX softirq then gets scheduled, this will take
the netif_tx_lock() a second time and deadlock the kernel.

To solve this, use netif_tx_lock_bh(), which blocks softirqs from
running.

CVE-2023-53026 RDMA/core: Fix ib block iterator counter overflow
In the Linux kernel, the following vulnerability has been resolved:

RDMA/core: Fix ib block iterator counter overflow

When registering a new DMA MR after selecting the best aligned page size
for it, we iterate over the given sglist to split each entry to smaller,
aligned to the selected page size, DMA blocks.

In given circumstances where the sg entry and page size fit certain
sizes and the sg entry is not aligned to the selected page size, the
total size of the aligned pages we need to cover the sg entry is >= 4GB.
Under this circumstances, while iterating page aligned blocks, the
counter responsible for counting how much we advanced from the start of
the sg entry is overflowed because its type is u32 and we pass 4GB in
size. This can lead to an infinite loop inside the iterator function
because the overflow prevents the counter to be larger
than the size of the sg entry.

Fix the presented problem by changing the advancement condition to
eliminate overflow.

CVE-2023-53029 octeontx2-pf: Fix the use of GFP_KERNEL in atomic context on rt
In the Linux kernel, the following vulnerability has been resolved:

octeontx2-pf: Fix the use of GFP_KERNEL in atomic context on rt

The commit 4af1b64f80fb ("octeontx2-pf: Fix lmtst ID used in aura
free") uses the get/put_cpu() to protect the usage of percpu pointer
in ->aura_freeptr() callback, but it also unnecessarily disable the
preemption for the blockable memory allocation. The commit 87b93b678e95
("octeontx2-pf: Avoid use of GFP_KERNEL in atomic context") tried to
fix these sleep inside atomic warnings. But it only fix the one for
the non-rt kernel. For the rt kernel, we still get the similar warnings
like below.

Of course, we can shuffle the get/put_cpu() to only wrap the invocation
of ->aura_freeptr() as what commit 87b93b678e95 does. But there are only
two ->aura_freeptr() callbacks, otx2_aura_freeptr() and
cn10k_aura_freeptr(). There is no usage of perpcu variable in the
otx2_aura_freeptr() at all, so the get/put_cpu() seems redundant to it.
We can move the get/put_cpu() into the corresponding callback which
really has the percpu variable usage and avoid the sprinkling of
get/put_cpu() in several places.

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

netfilter: ipset: Fix overflow before widen in the bitmap_ip_create() function.

When first_ip is 0, last_ip is 0xFFFFFFFF, and netmask is 31, the value of
an arithmetic expression 2 << (netmask - mask_bits - 1) is subject
to overflow due to a failure casting operands to a larger data type
before performing the arithmetic.

Note that it's harmless since the value will be checked at the next step.

nilfs2: fix kernel-infoleak in nilfs_ioctl_wrap_copy()

The ioctl helper function nilfs_ioctl_wrap_copy(), which exchanges a

and NILFS_IOCTL_GET_CPINFO.

This can occur when the element size of the user space metadata given by
the v_size member of the argument nilfs_argv structure is larger than the
size of the metadata element (nilfs_suinfo structure or nilfs_cpinfo
structure) on the file system side.

CVE-2023-53036 drm/amdgpu: Fix call trace warning and hang when removing amdgpu device
In the Linux kernel, the following vulnerability has been resolved:

drm/amdgpu: Fix call trace warning and hang when removing amdgpu device

On GPUs with RAS enabled, below call trace and hang are observed when
shutting down device.

v2: use DRM device unplugged flag instead of shutdown flag as the check to
prevent memory wipe in shutdown stage.

CVE-2023-53037 scsi: mpi3mr: Bad drive in topology results kernel crash
In the Linux kernel, the following vulnerability has been resolved:

scsi: mpi3mr: Bad drive in topology results kernel crash

When the SAS Transport Layer support is enabled and a device exposed to
the OS by the driver fails INQUIRY commands, the driver frees up the memory
allocated for an internal HBA port data structure. However, in some places,
the reference to the freed memory is not cleared. When the firmware sends
the Device Info change event for the same device again, the freed memory is
accessed and that leads to memory corruption and OS crash.

CVE-2023-53038 scsi: lpfc: Check kzalloc() in lpfc_sli4_cgn_params_read()
In the Linux kernel, the following vulnerability has been resolved:

scsi: lpfc: Check kzalloc() in lpfc_sli4_cgn_params_read()

If kzalloc() fails in lpfc_sli4_cgn_params_read(), then we rely on
lpfc_read_object()'s routine to NULL check pdata.

Currently, an early return error is thrown from lpfc_read_object() to
protect us from NULL ptr dereference, but the errno code is -ENODEV.

Change the errno code to a more appropriate -ENOMEM.

CVE-2023-53039 HID: intel-ish-hid: ipc: Fix potential use-after-free in work function
In the Linux kernel, the following vulnerability has been resolved:

HID: intel-ish-hid: ipc: Fix potential use-after-free in work function

When a reset notify IPC message is received, the ISR schedules a work
function and passes the ISHTP device to it via a global pointer
ishtp_dev. If ish_probe() fails, the devm-managed device resources
including ishtp_dev are freed, but the work is not cancelled, causing a
use-after-free when the work function tries to access ishtp_dev. Use
devm_work_autocancel() instead, so that the work is automatically
cancelled if probe fails.
