| In the Linux kernel, the following vulnerability has been resolved:
serial: arc_uart: fix of_iomap leak in `arc_serial_probe`
Smatch reports:
drivers/tty/serial/arc_uart.c:631 arc_serial_probe() warn:
'port->membase' from of_iomap() not released on lines: 631.
In arc_serial_probe(), if uart_add_one_port() fails,
port->membase is not released, which would cause a resource leak.
To fix this, I replace of_iomap with devm_platform_ioremap_resource. |
| NVIDIA Display Driver for Linux contains a vulnerability in a kernel module, where an attacker might be able to trigger a null pointer deference. A successful exploit of this vulnerability might lead to denial of service. |
| In the Linux kernel, the following vulnerability has been resolved:
thermal: intel: quark_dts: fix error pointer dereference
If alloc_soc_dts() fails, then we can just return. Trying to free
"soc_dts" will lead to an Oops. |
| In the Linux kernel, the following vulnerability has been resolved:
vduse: fix NULL pointer dereference
vduse_vdpa_set_vq_affinity callback can be called
with NULL value as cpu_mask when deleting the vduse
device.
This patch resets virtqueue's IRQ affinity mask value
to set all CPUs instead of dereferencing NULL cpu_mask.

cpufreq: qcom: fix memory leak in error path
If for some reason the speedbin length is incorrect, then there is a
memory leak in the error path because we never free the speedbin buffer.
This commit fixes the error path to always free the speedbin buffer. |

---truncated--- |
| In the Linux kernel, the following vulnerability has been resolved:
ipv4: start using dst_dev_rcu()
Change icmpv4_xrlim_allow(), ip_defrag() to prevent possible UAF.
Change ipmr_prepare_xmit(), ipmr_queue_fwd_xmit(), ip_mr_output(),
ipv4_neigh_lookup() to use lockdep enabled dst_dev_rcu(). |
| In the Linux kernel, the following vulnerability has been resolved:
scsi: ses: Fix possible addl_desc_ptr out-of-bounds accesses
Sanitize possible addl_desc_ptr out-of-bounds accesses in
ses_enclosure_data_process(). |
| In the Linux kernel, the following vulnerability has been resolved:
mmc: meson-gx: fix return value check of mmc_add_host()
mmc_add_host() may return error, if we ignore its return value,
it will lead two issues:
1. The memory that allocated in mmc_alloc_host() is leaked.
2. In the remove() path, mmc_remove_host() will be called to
delete device, but it's not added yet, it will lead a kernel
crash because of null-ptr-deref in device_del().
Fix this by checking the return value and goto error path which
will call mmc_free_host(). |
| In the Linux kernel, the following vulnerability has been resolved:
ipv6: use RCU in ip6_xmit()
Use RCU in ip6_xmit() in order to use dst_dev_rcu() to prevent
possible UAF. |
| In the Linux kernel, the following vulnerability has been resolved:
clk: imx93: fix memory leak and missing unwind goto in imx93_clocks_probe
In function probe(), it returns directly without unregistered hws
when error occurs.
Fix this by adding 'goto unregister_hws;' on line 295 and
line 310.
Use devm_kzalloc() instead of kzalloc() to automatically
free the memory using devm_kfree() when error occurs.
Replace of_iomap() with devm_of_iomap() to automatically
handle the unused ioremap region and delete 'iounmap(anatop_base);'
in unregister_hws. |
| In the Linux kernel, the following vulnerability has been resolved:
Revert "Bluetooth: btsdio: fix use after free bug in btsdio_remove due to unfinished work"
This reverts commit 1e9ac114c4428fdb7ff4635b45d4f46017e8916f.
This patch introduces a possible null-ptr-def problem. Revert it. And the
fixed bug by this patch have resolved by commit 73f7b171b7c0 ("Bluetooth:
btsdio: fix use after free bug in btsdio_remove due to race condition"). |

ALSA: firewire-motu: add bounds check in put_user loop for DSP events
In the DSP event handling code, a put_user() loop copies event data.
When the user buffer size is not aligned to 4 bytes, it could overwrite
beyond the buffer boundary.
Fix by adding a bounds check before put_user(). |
| In the Linux kernel, the following vulnerability has been resolved:
udmabuf: Set ubuf->sg = NULL if the creation of sg table fails
When userspace tries to map the dmabuf and if for some reason
(e.g. OOM) the creation of the sg table fails, ubuf->sg needs to be
set to NULL. Otherwise, when the userspace subsequently closes the
dmabuf fd, we'd try to erroneously free the invalid sg table from
release_udmabuf resulting in the following crash reported by syzbot:

net: hsr: avoid possible NULL deref in skb_clone()
syzbot got a crash [1] in skb_clone(), caused by a bug
in hsr_get_untagged_frame().
When/if create_stripped_skb_hsr() returns NULL, we must
not attempt to call skb_clone().
While we are at it, replace a WARN_ONCE() by netdev_warn_once().

| In the Linux kernel, the following vulnerability has been resolved:
ipv6: ensure sane device mtu in tunnels
Another syzbot report [1] with no reproducer hints
at a bug in ip6_gre tunnel (dev:ip6gretap0)
Since ipv6 mcast code makes sure to read dev->mtu once
and applies a sanity check on it (see commit b9b312a7a451
"ipv6: mcast: better catch silly mtu values"), a remaining
possibility is that a layer is able to set dev->mtu to
an underflowed value (high order bit set).
This could happen indeed in ip6gre_tnl_link_config_route(),
ip6_tnl_link_config() and ipip6_tunnel_bind_dev()
Make sure to sanitize mtu value in a local variable before
it is written once on dev->mtu, as lockless readers could
catch wrong temporary value.

| In the Linux kernel, the following vulnerability has been resolved:
rapidio: devices: fix missing put_device in mport_cdev_open
When kfifo_alloc fails, the refcount of chdev->dev is left incremental.
We should use put_device(&chdev->dev) to decrease the ref count of
chdev->dev to avoid refcount leak. |
| In the Linux kernel, the following vulnerability has been resolved:
xhci: dbc: Fix memory leak in xhci_alloc_dbc()
If DbC is already in use, then the allocated memory for the xhci_dbc struct
doesn't get freed before returning NULL, which leads to a memleak. |
| In the Linux kernel, the following vulnerability has been resolved:
ksmbd: fix possible memory leak in smb2_lock()
argv needs to be free when setup_async_work fails or when the current
process is woken up. |
