CVE-2023-28484 2 Debian, Xmlsoft 2 Debian Linux, Libxml2 2026-10-14 N/A 6.5 MEDIUM
In libxml2 before 2.10.4, parsing of certain invalid XSD schemas can lead to a NULL pointer dereference and subsequently a segfault. This occurs in xmlSchemaFixupComplexType in xmlschemas.c.
CVE-2023-3772 4 Debian, Fedoraproject, Linux and 1 more 6 Debian Linux, Fedora, Linux Kernel and 3 more 2026-10-14 N/A 5.5 MEDIUM
A flaw was found in the Linux kernel’s IP framework for transforming packets (XFRM subsystem). This issue may allow a malicious user with CAP_NET_ADMIN privileges to directly dereference a NULL pointer in xfrm_update_ae_params(), leading to a possible kernel crash and denial of service.
CVE-2023-3338 3 Debian, Linux, Netapp 3 Debian Linux, Linux Kernel, Active Iq Unified Manager 2026-10-14 N/A 6.5 MEDIUM
A null pointer dereference flaw was found in the Linux kernel's DECnet networking protocol. This issue could allow a remote user to crash the system.
CVE-2023-3212 5 Debian, Fedoraproject, Linux and 2 more 14 Debian Linux, Fedora, Linux Kernel and 11 more 2026-10-14 N/A 4.4 MEDIUM
A NULL pointer dereference issue was found in the gfs2 file system in the Linux kernel. It occurs on corrupt gfs2 file systems when the evict code tries to reference the journal descriptor structure after it has been freed and set to NULL. A privileged local user could use this flaw to cause a kernel panic.
CVE-2023-2953 4 Apple, Netapp, Openldap and 1 more 16 Macos, Active Iq Unified Manager, Clustered Data Ontap and 13 more 2026-10-14 N/A 7.5 HIGH
A vulnerability was found in openldap. This security flaw causes a null pointer dereference in ber_memalloc_x() function.
CVE-2023-2898 3 Debian, Linux, Netapp 12 Debian Linux, Linux Kernel, H300s and 9 more 2026-10-14 N/A 4.7 MEDIUM
There is a null-pointer-dereference flaw found in f2fs_write_end_io in fs/f2fs/data.c in the Linux kernel. This flaw allows a local privileged user to cause a denial of service problem.
CVE-2023-1095 2 Linux, Redhat 2 Linux Kernel, Enterprise Linux 2026-10-14 N/A 5.5 MEDIUM
In nf_tables_updtable, if nf_tables_table_enable returns an error, nft_trans_destroy is called to free the transaction object. nft_trans_destroy() calls list_del(), but the transaction was never placed on a list -- the list head is all zeroes, this results in a NULL pointer dereference.
CVE-2025-65835 2 Eddyverbruggen, Google 2 Cordova-plugin-x-socialsharing, Android 2026-10-14 N/A 6.2 MEDIUM
The Cordova plugin cordova-plugin-x-socialsharing (SocialSharing-PhoneGap-Plugin) for Android 6.0.4, registers an exported broadcast receiver nl.xservices.plugins.ShareChooserPendingIntent with an android.intent.action.SEND intent filter. The onReceive implementation accesses Intent.EXTRA_CHOSEN_COMPONENT without checking for null. If a broadcast is sent with extras present but without EXTRA_CHOSEN_COMPONENT, the code dereferences a null value and throws a NullPointerException. Because the receiver is exported and performs no permission or caller validation, any local application on the device can send crafted ACTION_SEND broadcasts to this component and repeatedly crash the host application, resulting in a local, unauthenticated application-level denial of service for any app that includes the plugin.
CVE-2025-55314 2 Foxit, Microsoft 3 Pdf Editor, Pdf Reader, Windows 2026-10-14 N/A 7.8 HIGH
An issue was discovered in Foxit PDF and Editor for Windows and macOS before 13.2 and 2025 before 2025.2. When pages in a PDF are deleted via JavaScript, the application may fail to properly update internal states. Subsequent annotation management operations assume these states are valid, causing dereference of invalid or released memory. This can lead to memory corruption, application crashes, and potentially allow an attacker to execute arbitrary code.

CVE-2026-44322 1 Free5gc 1 Free5gc 2026-10-14 N/A 7.5 HIGH
free5GC is an open-source implementation of the 5G core network. Prior to 4.2.2, free5GC's NEF PATCH /3gpp-pfd-management/v1/{afId}/transactions/{transId}/applications/{appId} handler panics with a nil-pointer dereference when the upstream UDR call fails AND the consumer wrapper returns err != nil together with a nil *ProblemDetails. The handler's errPfdData != nil branch builds its own problemDetailsErr correctly, but immediately after it reads problemDetails.Cause (the OTHER value, which is nil in this branch) and panics. Gin recovery converts the panic into HTTP 500, so a single PATCH against this endpoint returns 500 instead of the intended controlled error response whenever UDR access is failing. This vulnerability is fixed in 4.2.2.
CVE-2026-44317 1 Free5gc 1 Free5gc 2026-10-14 N/A 6.5 MEDIUM
free5GC is an open-source implementation of the 5G core network. Prior to 4.2.2, free5GC's PCF POST /npcf-policyauthorization/v1/app-sessions handler panics on a single authenticated request whose ascReqData.suppFeat == "1" (enabling traffic-routing feature negotiation) and whose medComponents entries supply an afAppId but NO AfRoutReq. The create path then calls provisioningOfTrafficRoutingInfo(smPolicy, appID, routeReq, ...) with routeReq == nil and dereferences routeReq.RouteToLocs (and other fields) without a nil check, causing runtime error: invalid memory address or nil pointer dereference. Gin recovery converts the panic into HTTP 500. This vulnerability is fixed in 4.2.2.
CVE-2026-44316 1 Free5gc 1 Free5gc 2026-10-14 N/A 7.5 HIGH
free5GC is an open-source implementation of the 5G core network. Prior to 4.2.2, free5GC's PCF POST /npcf-smpolicycontrol/v1/sm-policies handler (HandleCreateSmPolicyRequest) panics with a nil-pointer dereference when a downstream OpenAPI consumer call (UDR lookup) returns 404 Not Found and the consumer wrapper returns err != nil together with a nil response struct. The handler logs the OpenAPI error and continues executing instead of returning, then dereferences the nil response struct on a subsequent line and panics. Gin recovery converts the panic into HTTP 500, so a single attacker-shaped POST returns 500 instead of a clean 4xx whenever the downstream lookup fails. The PCF process keeps running. The trigger is a single POST containing input that causes the downstream UDR lookup to fail (e.g. an unknown DNN). In 4.2.1 this endpoint is also reachable WITHOUT an Authorization header because the PCF Npcf_SMPolicyControl route group is mounted without inbound auth middleware. This vulnerability is fixed in 4.2.2.
CVE-2026-44328 1 Free5gc 1 Free5gc 2026-10-14 N/A 8.2 HIGH
free5GC is an open-source implementation of the 5G core network. Prior to 4.2.2, free5GC's SMF mounts the UPI management route group without inbound OAuth2 middleware. On top of that, the DELETE /upi/v1/upNodesLinks/{upNodeRef} handler unconditionally dereferences upNode.UPF after the type-guarded async release, even though AN-typed nodes are constructed without a UPF object. As a result, a single unauthenticated DELETE /upi/v1/upNodesLinks/gNB1 request crashes the handler with a nil-pointer panic AND mutates the in-memory user-plane topology before panicking (the UpNodeDelete(upNodeRef) line runs first). This is an unauthenticated, state-mutating panic-DoS sink that an off-path network attacker can trigger by name against any AN entry. This vulnerability is fixed in 4.2.2.
CVE-2026-47335 1 Canonical 1 Ubuntu Linux 2026-10-14 N/A 5.5 MEDIUM
Ubuntu Linux 6.8 contains SAUCE patches with a possible NULL pointer dereference in the handling of AppArmor notifications. The bug can be triggered by an unprivileged local user. This can lead to a kernel panic.
CVE-2026-47337 1 Canonical 1 Ubuntu Linux 2026-10-14 N/A 3.3 LOW
Ubuntu Linux 6.8, 6.17 and 7.0 contain SAUCE patches with a possible NULL pointer dereference in the handling of AF_INET/AF_INET6 socket mediation. The bug can be triggered by an unprivileged local user. This can lead to a kernel oops.
CVE-2026-44323 1 Free5gc 1 Free5gc 2026-10-14 N/A 4.3 MEDIUM
free5GC is an open-source implementation of the 5G core network. Prior to 4.2.2, free5GC's UDR nudr-dr DELETE /subscription-data/{ueId}/{servingPlmnId}/ee-subscriptions/{subsId}/amf-subscriptions handler contains a nil-pointer dereference reachable from a single authenticated request, after one preparatory authenticated EE-subscription create. The handler checks _, ok = UESubsData.EeSubscriptionCollection[subsId] and sets a 404 problem-details on the miss path, but then continues to UESubsData.EeSubscriptionCollection[subsId].AmfSubscriptionInfos -- dereferencing the same missing entry instead of returning. Gin recovery converts the panic into HTTP 500, but the endpoint remains repeatedly panicable. This vulnerability is fixed in 4.2.2.
