In the Linux kernel, the following vulnerability has been resolved:
rpcrdma: Always release the rpcrdma_device's xa_array
Dai pointed out that the xa_init_flags() in rpcrdma_add_one() needs
to have a matching xa_destroy() in rpcrdma_remove_one() to release
underlying memory that the xarray might have accrued during
operation.

In the Linux kernel, the following vulnerability has been resolved:
iio: gts-helper: Fix memory leaks for the error path of iio_gts_build_avail_scale_table()
If per_time_scales[i] or per_time_gains[i] kcalloc fails in the for loop
of iio_gts_build_avail_scale_table(), the err_free_out will fail to call
kfree() each time when i is reduced to 0, so all the per_time_scales[0]
and per_time_gains[0] will not be freed, which will cause memory leaks.
Fix it by checking if i >= 0.

In the Linux kernel, the following vulnerability has been resolved:
bpf: Free dynamically allocated bits in bpf_iter_bits_destroy()
bpf_iter_bits_destroy() uses "kit->nr_bits <= 64" to check whether the
bits are dynamically allocated. However, the check is incorrect and may
cause a kmemleak as shown below:

That is because nr_bits will be set as zero in bpf_iter_bits_next()
after all bits have been iterated.
Fix the issue by setting kit->bit to kit->nr_bits instead of setting
kit->nr_bits to zero when the iteration completes in
bpf_iter_bits_next(). In addition, use "!nr_bits || bits >= nr_bits" to
check whether the iteration is complete and still use "nr_bits > 64" to
indicate whether bits are dynamically allocated. The "!nr_bits" check is
necessary because bpf_iter_bits_new() may fail before setting
kit->nr_bits, and this condition will stop the iteration early instead
of accessing the zeroed or freed kit->bits.
Considering the initial value of kit->bits is -1 and the type of
kit->nr_bits is unsigned int, change the type of kit->nr_bits to int.
The potential overflow problem will be handled in the following patch.

Linux Kernel < 6.1.116 - Memory Leak
In the Linux kernel, the following vulnerability has been resolved:
mlxsw: spectrum_ipip: Fix memory leak when changing remote IPv6 address
The device stores IPv6 addresses that are used for encapsulation in
linear memory that is managed by the driver.
Changing the remote address of an ip6gre net device never worked
properly, but since cited commit the following reproducer [1] would
result in a warning [2] and a memory leak [3]. The problem is that the
new remote address is never added by the driver to its hash table (and
therefore the device) and the old address is never removed from it.
Fix by programming the new address when the configuration of the ip6gre
net device changes and removing the old one. If the address did not
change, then the above would result in increasing the reference count of
the address and then decreasing it.

In the Linux kernel, the following vulnerability has been resolved:
pinctrl: intel: platform: fix error path in device_for_each_child_node()
The device_for_each_child_node() loop requires calls to
fwnode_handle_put() upon early returns to decrement the refcount of
the child node and avoid leaking memory if that error path is triggered.
There is one early returns within that loop in
intel_platform_pinctrl_prepare_community(), but fwnode_handle_put() is
missing.
Instead of adding the missing call, the scoped version of the loop can
be used to simplify the code and avoid mistakes in the future if new
early returns are added, as the child node is only used for parsing, and
it is never assigned.

Linux Kernel < 6.11.6 - Memory Leak
In the Linux kernel, the following vulnerability has been resolved:
bpf: Preserve param->string when parsing mount options
In bpf_parse_param(), keep the value of param->string intact so it can
be freed later. Otherwise, the kmalloc area pointed to by param->string
will be leaked as shown below:
