In the Linux kernel, the following vulnerability has been resolved:
software node: Correct a OOB check in software_node_get_reference_args()
software_node_get_reference_args() wants to get @index-th element, so
the property value requires at least '(index + 1) * sizeof(*ref)' bytes
but that can not be guaranteed by current OOB check, and may cause OOB
for malformed property.
Fix by using as OOB check '((index + 1) * sizeof(*ref) > prop->length)'.

In the Linux kernel, the following vulnerability has been resolved:
wifi: mt76: mt7996: drop fragments with multicast or broadcast RA
IEEE 802.11 fragmentation can only be applied to unicast frames.
Therefore, drop fragments with multicast or broadcast RA. This patch
addresses vulnerabilities such as CVE-2020-26145.

ACPICA: fix acpi parse and parseext cache leaks
ACPICA commit 8829e70e1360c81e7a5a901b5d4f48330e021ea5
I'm Seunghun Han, and I work for National Security Research Institute of
South Korea.
I have been doing a research on ACPI and found an ACPI cache leak in ACPI
early abort cases.
Boot log of ACPI cache leak is as follows:

I analyzed this memory leak in detail. I found that “Acpi-State” cache and
“Acpi-Parse” cache were merged because the size of cache objects was same
slab cache size.
I finally found “Acpi-Parse” cache and “Acpi-parse_ext” cache were leaked
using SLAB_NEVER_MERGE flag in kmem_cache_create() function.
Real ACPI cache leak point is as follows:

ACPICA: fix acpi operand cache leak in dswstate.c
ACPICA commit 987a3b5cf7175916e2a4b6ea5b8e70f830dfe732
I found an ACPI cache leak in ACPI early termination and boot continuing case.
When early termination occurs due to malicious ACPI table, Linux kernel
terminates ACPI function and continues to boot process. While kernel terminates
ACPI function, kmem_cache_destroy() reports Acpi-Operand cache leak.

I analyzed this memory leak in detail and found acpi_ds_obj_stack_pop_and_
delete() function miscalculated the top of the stack. acpi_ds_obj_stack_push()
function uses walk_state->operand_index for start position of the top, but
acpi_ds_obj_stack_pop_and_delete() function considers index 0 for it.
Therefore, this causes acpi operand memory leak.
This cache leak causes a security threat because an old kernel (<= 4.9) shows
memory locations of kernel functions in stack dump. Some malicious users
could use this information to neutralize kernel ASLR.
I made a patch to fix ACPI operand cache leak.

ftrace_mod_get_kallsym()
...
strscpy(module_name, mod_map->mod->name, MODULE_NAME_LEN);
...
The problem is when a module triggers an issue with ftrace and
sets ftrace_disable. The ftrace_disable is set when an anomaly is
discovered and to prevent any more damage, ftrace stops all text
modification. The issue that happened was that the ftrace_disable stops
more than just the text modification.
When a module is loaded, its init functions can also be traced. Because
kallsyms deletes the init functions after a module has loaded, ftrace
saves them when the module is loaded and function tracing is enabled. This
allows the output of the function trace to show the init function names
instead of just their raw memory addresses.
When a module is removed, ftrace_release_mod() is called, and if
ftrace_disable is set, it just returns without doing anything more. The
problem here is that it leaves the mod_list still around and if kallsyms
is called, it will call into this code and access the module memory that
has already been freed as it will return:
strscpy(module_name, mod_map->mod->name, MODULE_NAME_LEN);
Where the "mod" no longer exists and triggers a UAF bug.

In the Linux kernel, the following vulnerability has been resolved:
wifi: p54: prevent buffer-overflow in p54_rx_eeprom_readback()
Robert Morris reported:
|If a malicious USB device pretends to be an Intersil p54 wifi
|interface and generates an eeprom_readback message with a large
|eeprom->v1.len, p54_rx_eeprom_readback() will copy data from the
|message beyond the end of priv->eeprom.
|
|static void p54_rx_eeprom_readback(struct p54_common *priv,
| struct sk_buff *skb)
|{
| struct p54_hdr *hdr = (struct p54_hdr *) skb->data;
| struct p54_eeprom_lm86 *eeprom = (struct p54_eeprom_lm86 *) hdr->data;
|
| if (priv->fw_var >= 0x509) {
| memcpy(priv->eeprom, eeprom->v2.data,
| le16_to_cpu(eeprom->v2.len));
| } else {
| memcpy(priv->eeprom, eeprom->v1.data,
| le16_to_cpu(eeprom->v1.len));
| }
| [...]
The eeprom->v{1,2}.len is set by the driver in p54_download_eeprom().
The device is supposed to provide the same length back to the driver.
But yes, it's possible (like shown in the report) to alter the value
to something that causes a crash/panic due to overrun.
This patch addresses the issue by adding the size to the common device
context, so p54_rx_eeprom_readback no longer relies on possibly tampered
values... That said, it also checks if the "firmware" altered the value
and no longer copies them.
The one, small saving grace is: Before the driver tries to read the eeprom,
it needs to upload >a< firmware. the vendor firmware has a proprietary
license and as a reason, it is not present on most distributions by
default.

In the Linux kernel, the following vulnerability has been resolved:
Input: gpio-keys - fix a sleep while atomic with PREEMPT_RT
When enabling PREEMPT_RT, the gpio_keys_irq_timer() callback runs in
hard irq context, but the input_event() takes a spin_lock, which isn't
allowed there as it is converted to a rt_spin_lock().

Considering the gpio_keys_irq_isr() can run in any context, e.g. it can
be threaded, it seems there's no point in requesting the timer isr to
run in hard irq context.
Relax the hrtimer not to use the hard context.
