CVE-2026-17009

IBM AIX 7.2/7.3 and PowerVM VIOS 4.1 contain a NULL pointer dereference exploitable by a local attacker with low privileges, causing denial of service (CVSS 4.7 MEDIUM). Exploitation requires high complexity; no exploit code or in-the-wild activity is documented. The IBM support reference is prov...

K000163013: LibTIFF vulnerabilities CVE-2018-17000, CVE-2018-19210, CVE-2019-7663, CVE-2020-19131, and CVE-2020-19144

Security Advisory Description CVE-2018-17000 A NULL pointer dereference in the function TIFFmemcmp at tifunix.c called from TIFFWriteDirectoryTagTransferfunction in LibTIFF 4.0.9 allows an attacker to cause a denial-of-service through a crafted tiff file. This vulnerability can be triggered by th...

CVE-2026-74379

A flaw was found in the Linux kernel's dax/kmem module. This vulnerability occurs when the system attempts to remove a memory resource that was not fully initialized, leading to an attempt to access a null pointer. A local attacker could potentially trigger this condition, causing the system to...

CVE-2026-74335

A flaw was found in the Linux kernel's Berkeley Packet Filter BPF subsystem. This vulnerability occurs in the bpftaskfromvpid function when a cgroupskb program, running in a soft interrupt, attempts to look up a task that is in the process of exiting. If the task's process ID PID namespace is...

CVE-2026-63380 Libevent: Null Pointer Dereference in `evws_new_session`

Libevent is an event notification library. Prior to 2.2.2-alpha, libevent can dereference invalid list pointers in ws.c when evwsnewsession enters its error path after evhttpstartws succeeds but buffereventenablelocking fails. evwsconnectionfree sees a non-null httpserver and unconditionally call...

CVE-2026-74327

A flaw was found in the Linux kernel. A local attacker could trigger a null pointer dereference in the isvmareahugepages function. This occurs when findvmarea returns a NULL value, which is not properly handled before being dereferenced. Successful exploitation of this vulnerability could lead to...

CVE-2026-74304

A flaw was found in the Bluetooth subsystem of the Linux kernel, specifically within the hciqca module. This vulnerability occurs when the qcasetup function is called for hciuart devices connected through non-serdev paths, leading to a NULL pointer dereference. A local attacker could potentially...

CVE-2026-76881

A flaw was found in Wireshark. A NULL pointer dereference vulnerability exists within the CMS Cryptographic Message Syntax protocol dissector. This issue can be triggered by processing a specially crafted network capture file, leading to an application crash. A remote attacker could exploit this ...

CVE-2026-74303

A flaw was found in the Linux kernel's Bluetooth subsystem. The qcadmphdr function, when handling non-serdev devices, attempts to dereference a NULL pointer without proper validation. An attacker could potentially trigger this condition, leading to a system crash and a denial of service...

CVE-2026-74274

A flaw was found in the Linux kernel's CXL Compute Express Link driver. When endpoint decoders are removed from a CXL region's target array, the driver can fail to properly fill the resulting NULL pointer holes. This can lead to the system attempting to access a NULL pointer, causing a general...

CVE-2026-74286

A flaw was found in the Linux kernel's Packet Forwarding Control Protocol PFCP module. The module fails to properly allocate per-CPU statistics, leaving a pointer uninitialized. A local attacker can exploit this by creating a PFCP rtnetlink device, which triggers a null pointer dereference. This...

CVE-2026-76928

A flaw was found in Wireshark. A remote attacker could exploit a NULL pointer dereference vulnerability in the X.509IF protocol dissector. This could lead to a denial of service, making the application unavailable to legitimate users...
