CVE alerts for
SonicWall

A Zip Slip vulnerability in the SonicWall Network Security Manager (NSM) On-Prem file upload and archive processing functionality allows an attacker to extract files outside the intended destination directory using a specially crafted archive.

PassMark PerformanceTest before 11.1 build 1012, BurnInTest before 11.1 build 1000, and OSForensics before 11.1 build 1016 contain an information disclosure vulnerability in DirectIo64.sys that allows unauthenticated local attackers to dump complete physical memory contents by supplying a caller-controlled file path to an exposed IOCTL. Attackers can issue a single IOCTL call to trigger the driver to iterate all physical memory ranges via MmGetPhysicalMemoryRanges and map each page through ZwMapViewOfSection on the PhysicalMemory section object, writing a full RAM image to an attacker-specified path in the SYSTEM context, bypassing user-mode ACLs and exposing LSASS working set, process memory, and cryptographic material from all running processes.

PassMark PerformanceTest before 11.1 build 1012, BurnInTest before 11.1 build 1000, and OSForensics before 11.1 build 1016 contain an unauthenticated physical memory disclosure in DirectIo64.sys, reachable by unprivileged local users through a single IOCTL with no caller-identity check. The handler writes a crash-dump-format (PAGEDU64) image of all physical memory to a caller-supplied file path in the SYSTEM context, allowing a standard user to create files in locations they cannot otherwise write and to recover memory belonging to processes of other users. The image is preceded by a header that exposes the kernel loaded-module list, active-process list and PFN database pointers, defeating KASLR. The same handler also dereferences the return value of an internal kernel-structure locator without a NULL check; that locator returns NULL on three distinct failure paths, and a kernel crash results on builds where any of those paths is taken.

PassMark PerformanceTest before 11.1 build 1012, BurnInTest before 11.1 build 1000, and OSForensics before 11.1 build 1016 contain a privilege escalation vulnerability in DirectIo64.sys that allows local users to issue arbitrary IN and OUT instructions to any x86 I/O port due to missing allowlist or port validation on exposed IOCTLs. Attackers can obtain a device handle and write to sensitive ports including the PS/2 controller port, CPU reset ports, CMOS configuration ports, and interrupt controller ports to cause an immediate system reset or other hardware-level manipulation from a standard user account.

PassMark PerformanceTest before 11.1 build 1012, BurnInTest before 11.1 build 1000, and OSForensics before 11.1 build 1016 contain a privilege escalation vulnerability in DirectIo64.sys that allows local users to modify hardware configuration by exploiting exposed IOCTLs with no validation on device selection, register offset, or value. Attackers can obtain a device handle and issue arbitrary PCI configuration space read/write operations to enable Bus Master DMA on any PCI device, halt storage controller I/O by clearing command registers, or remap Base Address Registers to redirect DMA to an attacker-chosen physical address.

PassMark PerformanceTest before 11.1 build 1012, BurnInTest before 11.1 build 1000, and OSForensics before 11.1 build 1016 contain a privilege escalation and denial-of-service vulnerability in DirectIo64.sys that allows local attackers to read arbitrary Model-Specific Registers or write zero to any MSR through exposed IOCTLs with insufficient blocklist enforcement. Attackers can exploit the unrestricted write IOCTL to zero out the system call handler MSR, causing an immediate unrecoverable kernel crash on the next system call, or read security-sensitive MSRs used to locate kernel data structures.

PassMark PerformanceTest before 11.1 build 1012, BurnInTest before 11.1 build 1000, and OSForensics before 11.1 build 1016 contain a hard-coded credentials vulnerability in DirectIo64.sys that allows local attackers to perform arbitrary physical memory writes by extracting an 8-byte key embedded as a hardcoded literal in the distributed binary and computing valid MD5 authentication tags for arbitrary IOCTL write requests. Attackers can additionally bypass a secondary validation gate by using the driver's own bit-clear IOCTL to clear a single bit in the gating instruction's displacement byte, causing all subsequent write requests to skip MAC verification, size checks, and Vendor ID checks entirely.

PassMark PerformanceTest before 11.1 build 1012, BurnInTest before 11.1 build 1000, and OSForensics before 11.1 build 1016 contain a privilege escalation vulnerability in DirectIo64.sys that allows local users to clear arbitrary bits at any physical memory address due to missing validation of the physical address parameter in an exposed IOCTL handler. Attackers can obtain a device handle and supply an arbitrary 64-bit physical address with a bit index to invoke MmMapIoSpace and clear bits in kernel code pages or page table entries, enabling local privilege escalation or system compromise.

PassMark PerformanceTest before 11.1 build 1012, BurnInTest before 11.1 build 1000, and OSForensics before 11.1 build 1016 contain an improper access control vulnerability in the DirectIo64.sys kernel driver that allows unprivileged local users to perform privileged hardware operations by opening a handle to the device object created without a security descriptor. Attackers can issue IOCTLs through the permissive default Windows ACL applied to the device to access restricted hardware operations regardless of privilege or integrity level.

A missing authorization vulnerability in the SonicWall Network Security Manager (NSM) On-Prem Management interface allows a lower-privileged Admin user to escalate privileges to SuperAdmin.

An Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') vulnerability in the SonicWall Network Security Manager (NSM) On-Prem Management interface allows an authenticated attacker with SuperAdmin privileges to inject arbitrary commands that are executed on the underlying host, resulting in remote code execution.

undici's decompress interceptor decompresses response bodies according to the untrusted Content-Encoding header. While the number of content-encoding layers is capped, the total decompressed output size is unbounded and there is no configuration option to limit it. A malicious or faulty upstream can therefore return a small compressed payload, a compression bomb, that expands to hundreds of megabytes or more in client memory, an asymmetric resource consumption that can exhaust memory and crash the process. This affects undici versions from 7.15.0 up to 7.29.1 and from 8.0.0 up to 8.10.2. Users should upgrade to undici 7.29.1 or 8.10.2.

In the Linux kernel, the following vulnerability has been resolved: iommufd: Fix wrong hwpt passed to iommufd_auto_response_faults on replace iommufd_hwpt_replace_device() calls: iommufd_auto_response_faults(hwpt, old_handle); passing the *new* hwpt together with the handle of the device's *old* domain. This should be a parameter mismatch: 1. Semantically, iommufd_auto_response_faults(x, handle) scans x->fault's deliver list and response xarray for groups matching "handle". A group is queued under the hwpt that was attached at fault-delivery time. old_handle is fetched *before* the domain switch, so its group lives on old->fault, not on the new hwpt->fault. 2. Historically, the first argument was "old". The routine was introduced by commit b7d8833677ba ("iommufd: Fault-capable hwpt attach/detach/replace") as __fault_domain_replace_dev() in fault.c, correctly calling iommufd_auto_response_faults(old, curr). Commit fb21b1568ada ("iommufd: Make attach_handle generic than fault specific") moved this into iommufd_hwpt_replace_device() in device.c and swapped it to "hwpt". This should be a refactor regression, not an intentional change. Fix this by passing "old" instead.

In the Linux kernel, the following vulnerability has been resolved: erofs: cap LZMA stream pool size fs/erofs/decompressor_lzma.c sizes the module-global MicroLZMA stream pool from num_possible_cpus() when the lzma_streams module parameter is unset, then z_erofs_load_lzma_config() preallocates one image-supplied dictionary per stream, accepting dictionaries up to 8 MiB. On high-CPU systems, a small EROFS image can pin hundreds of MiB of vmalloc-backed decoder state until the erofs module is unloaded. Impact: An EROFS image mounted by the system can pin up to 8 MiB of vmalloc memory per LZMA stream, either as intended or unexpectedly. Bound the default stream count by a new CONFIG_EROFS_FS_ZIP_LZMA_DEFAULT_MAX_STREAMS option, default 16, so the worst-case default preallocation is 128 MiB if the number of CPUs is no less than 16 while preserving the existing per-image dictionary limit. An explicit lzma_streams module parameter is still honoured as-is, so administrators who deliberately size the pool are not affected.

In the Linux kernel, the following vulnerability has been resolved: sctp: reject stale cookies with mismatched verification tags sctp_unpack_cookie() skips cookie expiration checks whenever an association already exists. This is broader than the exception in RFC 9260 Section 5.2.4. For an existing association, Section 5.2.4 permits an expired State Cookie only when both Verification Tags in the cookie match the current association. Otherwise, the packet SHOULD be discarded and a Stale Cookie ERROR MUST be sent. The broad check lets an expired Action A restart cookie reach sctp_sf_do_dupcook_a(). In a runtime test with the default 60 second cookie lifetime, replaying such a cookie after 65 seconds returned a COOKIE-ACK and restarted the association. Check cookie expiration unless both Verification Tags match. This preserves the Action D exception for a lost COOKIE ACK while rejecting expired cookies in all other cases.
