Security Vulnerabilities - CVEs Published In October 2024
In the Linux kernel, the following vulnerability has been resolved:
gpio/rockchip: fix refcount leak in rockchip_gpiolib_register()
The node returned by of_get_parent() with refcount incremented,
of_node_put() needs be called when finish using it. So add it in the
end of of_pinctrl_get().

In the Linux kernel, the following vulnerability has been resolved:
net: mvneta: Prevent out of bounds read in mvneta_config_rss()
The pp->indir[0] value comes from the user. It is passed to:
if (cpu_online(pp->rxq_def))
inside the mvneta_percpu_elect() function. It needs bounds checkeding
to ensure that it is not beyond the end of the cpu bitmap.

In the Linux kernel, the following vulnerability has been resolved:
NFC: nci: Bounds check struct nfc_target arrays
While running under CONFIG_FORTIFY_SOURCE=y, syzkaller reported:
memcpy: detected field-spanning write (size 129) of single field "target->sensf_res" at net/nfc/nci/ntf.c:260 (size 18)
This appears to be a legitimate lack of bounds checking in
nci_add_new_protocol(). Add the missing checks.

octeontx2-pf: Fix potential memory leak in otx2_init_tc()
In otx2_init_tc(), if rhashtable_init() failed, it does not free
tc->tc_entries_bitmap which is allocated in otx2_tc_alloc_ent_bitmap().

In the Linux kernel, the following vulnerability has been resolved:
dpaa2-switch: Fix memory leak in dpaa2_switch_acl_entry_add() and dpaa2_switch_acl_entry_remove()
The cmd_buff needs to be freed when error happened in
dpaa2_switch_acl_entry_add() and dpaa2_switch_acl_entry_remove().

In the Linux kernel, the following vulnerability has been resolved:
ethernet: aeroflex: fix potential skb leak in greth_init_rings()
The greth_init_rings() function won't free the newly allocated skb when
dma_mapping_error() returns error, so add dev_kfree_skb() to fix it.
Compile tested only.

In the Linux kernel, the following vulnerability has been resolved:
net: hisilicon: Fix potential use-after-free in hix5hd2_rx()
The skb is delivered to napi_gro_receive() which may free it, after
calling this, dereferencing skb may trigger use-after-free.

In the Linux kernel, the following vulnerability has been resolved:
net: mdio: fix unbalanced fwnode reference count in mdio_device_release()
There is warning report about of_node refcount leak
while probing mdio device:
OF: ERROR: memory leak, expected refcount 1 instead of 2,
of_node_get()/of_node_put() unbalanced - destroy cset entry:
attach overlay node /spi/soc@0/mdio@710700c0/ethernet@4
In of_mdiobus_register_device(), we increase fwnode refcount
by fwnode_handle_get() before associating the of_node with
mdio device, but it has never been decreased in normal path.
Since that, in mdio_device_release(), it needs to call
fwnode_handle_put() in addition instead of calling kfree()
directly.
After above, just calling mdio_device_free() in the error handle
path of of_mdiobus_register_device() is enough to keep the
refcount balanced.

In the Linux kernel, the following vulnerability has been resolved:
udf: Fix preallocation discarding at indirect extent boundary
When preallocation extent is the first one in the extent block, the
code would corrupt extent tree header instead. Fix the problem and use
udf_delete_aext() for deleting extent to avoid some code duplication.
