libfuse versions 3.18.0 through 3.18.1 contain a NULL pointer dereference and memory leak vulnerability in the fuse_uring_init_queue function that affects only the io_uring transport implementation. A local user with low privileges can trigger this vulnerability to crash the FUSE daemon or exhaust system resources through repeated exploitation. A proof-of-concept has been confirmed with AddressSanitizer and LeakSanitizer, demonstrating both the NULL dereference condition and memory leak when numa_alloc_local or fuse_uring_register_queue fail.

A NULL pointer dereference vulnerability exists in the Linux kernel's TEQL (Trivial Ethernet Queue Limiting) network scheduler when transmitting through tunnel slave devices, particularly gretap tunnels. The vulnerability occurs because teql_master_xmit() fails to update skb->dev to the slave device before transmission, causing tunnel xmit functions to reference unallocated per-CPU statistics on the TEQL master device. This allows a local or networked attacker to trigger a kernel page fault and crash the system, resulting in a denial of service. No CVSS score, EPSS risk score, or KEV active exploitation status is currently published, but patch commits are available in Linux kernel stable branches (6.18.19, 6.19.9, and 7.0-rc4).

Ella Core contains a null pointer dereference vulnerability (CWE-476) that causes the process to panic when processing malformed UL NAS Transport NAS messages that lack a Request Type field, particularly when no SM Context is present. An attacker with network access and minimal privileges can send crafted NAS messages to trigger this crash, resulting in complete denial of service for all connected subscribers without requiring authentication. The CVSS 6.5 score reflects the high availability impact, though the requirement for low privileges (PR:L) and network-only access (AV:N) constrains the overall severity.

Ella Core is vulnerable to a denial of service attack via a null pointer dereference when processing malformed NGAP LocationReport messages that omit the required UEPresenceInAreaOfInterestList field. An unauthenticated attacker with network access can crash the Ella Core process, disrupting service for all connected subscribers. No patch is currently available.

The DataChangeNotificationProcedure function in notifier.go fails to validate pointers before dereferencing, causing complete service disruption requiring manual restart. All deployments of free5GC v4.0.1 utilizing UDM HTTP callback functionality are affected, and a patch is available via PR free5gc/udm#78.

The free5GC AUSF authentication service is vulnerable to denial of service through an improper null check in the GetSupiFromSuciSupiMap function, which crashes when processing crafted UE authentication requests that trigger unsafe interface conversion. Remote attackers can exploit this vulnerability to completely disable the AUSF service by sending a specially crafted authentication request containing a nil SuciSupiMap value. A patch is available for affected free5GC v4.0.1 deployments.

This vulnerability in the Linux kernel's XFS filesystem code involves improper pointer validation in xfarray and xfblob destructor functions, where the destructors can be called with invalid (dangling) pointers if the pointer is not properly nulled after deallocation. The vulnerability affects Linux kernel versions 6.9 through 6.10 and later patch versions, potentially allowing information disclosure or system instability. While no CVSS score or exploitation data is publicly available, the fix was backported across multiple kernel versions (6.12.75, 6.18.16, 6.19.6, 7.0-rc1) indicating recognition of the issue's significance across the kernel maintenance community.

A null pointer dereference vulnerability exists in the XFS filesystem checker (xchk_scrub_create_subord) in the Linux kernel, where the function returns a mangled ENOMEM error instead of NULL, and callers fail to properly validate the return value.

A null pointer dereference vulnerability exists in the Linux kernel's XFS filesystem repair code when revalidating B-tree structures during fsck operations. The vulnerability affects Linux kernel versions across multiple release branches (6.8, 6.12.75, 6.18.16, 6.19.6, and 7.0-rc1) when the xfs_scrub utility attempts to repair both the free space B-tree (bnobt) and count B-tree (cntbt) simultaneously. An authenticated attacker with fsck/scrub privileges can trigger a kernel crash (denial of service) by injecting corruption markers via XFS_IOC_ERROR_INJECTION ioctl, causing the kernel to crash when the second B-tree revalidation is attempted after the first one fails and nullifies a required cursor.

A null pointer dereference vulnerability exists in the Linux kernel's RDMA/siw (Software iWARP) module in the TCP receive data path handler. When siw_get_hdr() returns an error before initializing the receive FPDU context, the error handling code attempts to dereference qp->rx_fpdu without null checking, potentially causing a kernel panic and denial of service. The vulnerability affects multiple Linux kernel versions across stable branches (5.10, 5.15, 6.1, 6.6, 6.12, and others) and has been patched across numerous kernel releases.
