| A buffer copy without checking size of input vulnerability has been reported to affect several QNAP operating system versions. If exploited, the vulnerability could allow remote attackers who have gained administrator access to execute code.
We have already fixed the vulnerability in the following versions:
QTS 5.2.1.2930 build 20241025 and later

| In the Linux kernel, the following vulnerability has been resolved:
net: dsa: Avoid cross-chip syncing of VLAN filtering
Changes to VLAN filtering are not applicable to cross-chip
notifications.
On a system like this:
.-----. .-----. .-----.
| sw1 +---+ sw2 +---+ sw3 |
'-1-2-' '-1-2-' '-1-2-'
Before this change, upon sw1p1 leaving a bridge, a call to
dsa_port_vlan_filtering would also be made to sw2p1 and sw3p1.
In this scenario:
.---------. .-----. .-----.
| sw1 +---+ sw2 +---+ sw3 |
'-1-2-3-4-' '-1-2-' '-1-2-'
When sw1p4 would leave a bridge, dsa_port_vlan_filtering would be
called for sw2 and sw3 with a non-existing port - leading to array
out-of-bounds accesses and crashes on mv88e6xxx. |
| In the Linux kernel, the following vulnerability has been resolved:
drm/i915/gem: add missing boundary check in vm_access
A missing bounds check in vm_access() can lead to an out-of-bounds read
or write in the adjacent memory area, since the len attribute is not
validated before the memcpy later in the function, potentially hitting:

| In the Linux kernel, the following vulnerability has been resolved:
ASoC: codecs: rx-macro: fix accessing array out of bounds for enum type
Accessing enums using integer would result in array out of bounds access
on platforms like aarch64 where sizeof(long) is 8 compared to enum size
which is 4 bytes. |
| In the Linux kernel, the following vulnerability has been resolved:
ASoC: codecs: va-macro: fix accessing array out of bounds for enum type
Accessing enums using integer would result in array out of bounds access
on platforms like aarch64 where sizeof(long) is 8 compared to enum size
which is 4 bytes. |
| In the Linux kernel, the following vulnerability has been resolved:
ASoC: codecs: rx-macro: fix accessing compander for aux
AUX interpolator does not have compander, so check before accessing
compander data for this.
Without this checkan array of out bounds access will be made in
comp_enabled[] array. |
| In the Linux kernel, the following vulnerability has been resolved:
ASoC: codecs: wc938x: fix accessing array out of bounds for enum type
Accessing enums using integer would result in array out of bounds access
on platforms like aarch64 where sizeof(long) is 8 compared to enum size
which is 4 bytes.
Fix this by using enumerated items instead of integers. |
| Ashlar-Vellum Graphite VC6 File Parsing Heap-based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Ashlar-Vellum Graphite. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.
The specific flaw exists within the parsing of VC6 files. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a heap-based buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-25477. |
