CVE-2026-64240
A flaw was found in the Linux kernel's igorplugusb driver. This vulnerability occurs because the driver incorrectly passes a pointer instead of the actual USB control request setup packet to the USB core. As a result, the USB core misinterprets the data, leading to an invalid request type and...
CVE-2026-64234
A flaw was found in the Linux kernel's tty subsystem, specifically within the pchuart serial driver. This vulnerability occurs due to a missing check for the return value of dmaalloccoherent. An attacker could potentially exploit this to trigger a NULL pointer dereference in the dmahandlerx...
kernel: iommu/vt-d: Avoid NULL pointer dereference or refcount corruption
A flaw was found in the Linux kernel's Input-Output Memory Management Unit IOMMU virtualized direct memory access VT-d component. This vulnerability occurs when the system attempts to perform cleanup operations without a valid device identifier, leading to a null pointer dereference or incorrect...

CVE-2026-64246
A flaw was found in the Linux kernel's linkstation-poweroff module. An issue exists where a use-after-free vulnerability occurs due to incorrect handling of a node pointer in the linkstationpoweroffinit function. This flaw could lead to memory corruption, potentially causing system instability or...
CVE-2026-17574
A flaw was found in HDF5. A local user can exploit this vulnerability by processing a specially crafted HDF5 file. This file, containing an attribute with an invalid variable-length datatype, can cause a NULL pointer dereference, leading to an application crash and resulting in a denial of servic...
CVE-2026-64253
A flaw was found in the Linux kernel. The copyprocess function, responsible for creating new processes, incorrectly inherits a flag PFBLOCKTS from the parent process while simultaneously setting a related pointer current-plug to null in the child process. This inconsistency can lead to the kernel...
evtchn: Race between FIFO expand and reset
ISSUE DESCRIPTION The EVTCHNOPexpandarray hypercall checks for whether FIFO event channels are enabled, but without holding the correct lock. It can race with EVTCHNOPreset, resulting in dereferencing a NULL pointer. IMPACT A malicious HVM guest x86 HVM or PVH, and ARM can crash Xen leading to a...
CVE-2026-64215
A flaw was found in the Linux kernel's drm/msm/a6xx component. This vulnerability occurs because the a8xxhfisendperftable function does not properly check the return value of a memory allocation call kzalloc. An attacker could potentially exploit this missing check to trigger a NULL pointer...
httpd: NULL pointer dereference via specially crafted request
A flaw was found in the moddavlock module of httpd. This vulnerability allows a remote unauthenticated attacker to crash the server due to a NULL pointer dereference via a specially crafted request...
httpd: mod_authn_socache: NULL pointer dereference can cause a child process crash
A flaw was found in the modauthnsocache module of httpd. This vulnerability allows an unauthenticated remote user to crash a child process due to a NULL pointer dereference when the server is operating in a caching forward proxy configuration...
CVE-2026-64212
A flaw was found in the Linux kernel's iwlwifi driver. The iwlmldremovelink function does not properly check for a NULL pointer before dereferencing it. A local attacker could potentially exploit this null pointer dereference, leading to a system crash and a Denial of Service DoS...
