| In the Linux kernel, the following vulnerability has been resolved:
usb: typec: wusb3801: fix fwnode refcount leak in wusb3801_probe()
I got the following report while doing fault injection test:
OF: ERROR: memory leak, expected refcount 1 instead of 4,
of_node_get()/of_node_put() unbalanced - destroy cset entry:
attach overlay node /i2c/tcpc@60/connector
If wusb3801_hw_init() fails, fwnode_handle_put() needs be called to
avoid refcount leak. |
| In the Linux kernel, the following vulnerability has been resolved:
erofs: fix missing unmap if z_erofs_get_extent_compressedlen() fails
Otherwise, meta buffers could be leaked. |
| In the Linux kernel, the following vulnerability has been resolved:
auxdisplay: hd44780: Fix potential memory leak in hd44780_remove()
hd44780_probe() allocates a memory chunk for hd with kzalloc() and
makes "lcd->drvdata->hd44780" point to it. When we call hd44780_remove(),
we should release all relevant memory and resource. But "lcd->drvdata
->hd44780" is not released, which will lead to a memory leak.
We should release the "lcd->drvdata->hd44780" in hd44780_remove() to fix
the memory leak bug. |
| In the Linux kernel, the following vulnerability has been resolved:
scsi: lpfc: Fix memory leak in lpfc_create_port()
Commit 5e633302ace1 ("scsi: lpfc: vmid: Add support for VMID in mailbox
command") introduced allocations for the VMID resources in
lpfc_create_port() after the call to scsi_host_alloc(). Upon failure on the
VMID allocations, the new code would branch to the 'out' label, which
returns NULL without unwinding anything, thus skipping the call to
scsi_host_put().
Fix the problem by creating a separate label 'out_free_vmid' to unwind the
VMID resources and make the 'out_put_shost' label call only
scsi_host_put(), as was done before the introduction of allocations for
VMID. |

The issue is that the per-device running_req read in
pm8001_dev_gone_notify() never goes to zero and we never make progress.
This is caused by missing accounting for running_req for when an internal
abort command completes.
In commit 2cbbf489778e ("scsi: pm8001: Use libsas internal abort support")
we started to send internal abort commands as a proper sas_task. In this
when we deliver a sas_task to HW the per-device running_req is incremented
in pm8001_queue_command(). However it is never decremented for internal
abort commnds, so decrement in pm8001_mpi_task_abort_resp(). |
| In the Linux kernel, the following vulnerability has been resolved:
net/mlx5e: xsk: Fix invalid buffer access for legacy rq
The below crash can be encountered when using xdpsock in rx mode for
legacy rq: the buffer gets released in the XDP_REDIRECT path, and then
once again in the driver. This fix sets the flag to avoid releasing on
the driver side.
XSK handling of buffers for legacy rq was relying on the caller to set
the skip release flag. But the referenced fix started using fragment
counts for pages instead of the skip flag.

cifs: Fix lost destroy smbd connection when MR allocate failed
If the MR allocate failed, the smb direct connection info is NULL,
then smbd_destroy() will directly return, then the connection info

Let's set the smb direct connection info to the server before call
smbd_destroy(). |
| In the Linux kernel, the following vulnerability has been resolved:
sh: dma: Fix DMA channel offset calculation
Various SoCs of the SH3, SH4 and SH4A family, which use this driver,
feature a differing number of DMA channels, which can be distributed
between up to two DMAC modules. The existing implementation fails to
correctly accommodate for all those variations, resulting in wrong
channel offset calculations and leading to kernel panics.
Rewrite dma_base_addr() in order to properly calculate channel offsets
in a DMAC module. Fix dmaor_read_reg() and dmaor_write_reg(), so that
the correct DMAC module base is selected for the DMAOR register. |
| In the Linux kernel, the following vulnerability has been resolved:
netfilter: ebtables: fix table blob use-after-free
We are not allowed to return an error at this point.
Looking at the code it looks like ret is always 0 at this
point, but its not.
t = find_table_lock(net, repl->name, &ret, &ebt_mutex);
... this can return a valid table, with ret != 0.
This bug causes update of table->private with the new
blob, but then frees the blob right away in the caller.

misc: pci_endpoint_test: Free IRQs before removing the device
In pci_endpoint_test_remove(), freeing the IRQs after removing the device
creates a small race window for IRQs to be received with the test device
memory already released, causing the IRQ handler to access invalid memory,
resulting in an oops.
Free the device IRQs before removing the device to avoid this issue. |

wifi: mac80211: fortify the spinlock against deadlock by interrupt
In the function ieee80211_tx_dequeue() there is a particular locking
sequence:
begin:
spin_lock(&local->queue_stop_reason_lock);
q_stopped = local->queue_stop_reasons[q];
spin_unlock(&local->queue_stop_reason_lock);
However small the chance (increased by ftracetest), an asynchronous
interrupt can occur in between of spin_lock() and spin_unlock(),
and the interrupt routine will attempt to lock the same
&local->queue_stop_reason_lock again.
This will cause a costly reset of the CPU and the wifi device or an
altogether hang in the single CPU and single core scenario.
The only remaining spin_lock(&local->queue_stop_reason_lock) that
did not disable interrupts was patched, which should prevent any
deadlocks on the same CPU/core and the same wifi device.
This is the probable trace of the deadlock:

The root cause is the deletion of kvm_mips_commpage_init() leaves vcpu
->arch.cop0 NULL. So fix it by making cop0 from a pointer to an embedded
object. |
| In the Linux kernel, the following vulnerability has been resolved:
wifi: ath11k: Fix memory leak in ath11k_peer_rx_frag_setup
crypto_alloc_shash() allocates resources, which should be released by
crypto_free_shash(). When ath11k_peer_find() fails, there has memory
leak. Add missing crypto_free_shash() to fix this. |
| In the Linux kernel, the following vulnerability has been resolved:
media: dvb-usb: m920x: Fix a potential memory leak in m920x_i2c_xfer()
'read' is freed when it is known to be NULL, but not when a read error
occurs.
Revert the logic to avoid a small leak, should a m920x_read() call fail. |
| In the Linux kernel, the following vulnerability has been resolved:
xfrm: Fix leak of dev tracker
At the stage of direction checks, the netdev reference tracker is
already initialized, but released with wrong *_put() call. |
