CVE-2026-31744

A flaw was found in the Linux kernel. When processing energy model performance domains, the devenergymodelnlgetperfdomainsdoit function fails to validate the return value from emperfdomaingetbyid. If a non-existent performance domain ID is provided, this leads to a null pointer dereference, which...

CVE-2026-31736

A flaw was found in the Linux kernel's mtkppe Ethernet driver. When the gmac0 interface is disabled, a precheck for a valid ingress device can lead to a NULL pointer dereference. This vulnerability can cause a system crash, resulting in a Denial of Service DoS...

CVE-2026-31728

A flaw was found in the Linux kernel's usb: gadget: uether module. A race condition between the getherdisconnect and ethstop functions can lead to a NULL pointer dereference. This occurs when ethstop is triggered concurrently while getherdisconnect is tearing down USB endpoints. The vulnerability...

CVE-2026-31727

A flaw was found in the Linux kernel's USB gadget subsystem, specifically within the uether module. A local user can exploit this vulnerability by using a userspace tool to query a USB gadget interface during a specific detached state. This action can trigger a NULL pointer dereference, potential...

CVE-2026-31726

A flaw was found in the Linux kernel's USB Video Class UVC gadget driver. A race condition during power management PM transitions can cause a null pointer dereference. This occurs when the system attempts to access a deallocated gadget pointer, leading to a kernel panic. This vulnerability can be...

CVE-2026-31715

A flaw was found in the Linux kernel's Flash-Friendly File System f2fs. A use-after-free vulnerability exists due to incorrect handling of page counts during concurrent write operations and unmounting. This can lead to a NULL pointer dereference, causing the system to panic and resulting in a...

CVE-2026-43043

A flaw was found in the Linux kernel's af-alg subsystem. When the AFALG interface chains a new afalgtsgl structure, it fails to unmark the end of a Scatter/Gather List SGL. This can lead to a NULL pointer dereference during a subsequent sendmsg operation, causing a kernel panic and resulting in a...

CVE-2026-35233

An unprivileged attacker can craft a user-space process with a malicious ELF binary containing an out-of-range shlink field. When root-level dtrace attaches to -- or instruments -- that process via dtrace -p , pid probes, or USDT, the ELF parser reads heap memory beyond the allocated section cach...

NULL Pointer Dereference

Overview Affected versions of this package are vulnerable to NULL Pointer Dereference in the TShape process. An attacker can cause the application to crash or become unresponsive by submitting a specially crafted VRML file that triggers dereference of a corrupt or unvalidated pointer during shape...

Consequently, the initialization flow proceeds to call mlx5ldevadddebugfs ev...

CVE-2026-31755

In the Linux kernel, the following vulnerability has been resolved: usb: cdns3: gadget: fix NULL pointer dereference in epqueue When the gadget endpoint is disabled or not yet configured, the ep-desc pointer can be NULL. This leads to a NULL pointer dereference when cdns3gadgetepqueue is called,...

CVE-2026-31744

In the Linux kernel, the following vulnerability has been resolved: PM: EM: Fix NULL pointer dereference when perf domain ID is not found devenergymodelnlgetperfdomainsdoit calls emperfdomaingetbyid but does not check the return value before passing it to emnlgetpdsize. When a caller supplies a...

CVE-2026-31736

In the Linux kernel, the following vulnerability has been resolved: net: ethernet: mtkppe: avoid NULL deref when gmac0 is disabled If the gmac0 is disabled, the precheck for a valid ingress device will cause a NULL pointer deref and crash the system. This happens because eth-netdev0 will be NULL...

CVE-2026-31727

In the Linux kernel, the following vulnerability has been resolved: usb: gadget: uether: Fix NULL pointer deref in ethgetdrvinfo Commit ec35c1969650 "usb: gadget: fncm: Fix netdevice lifecycle with devicemove" reparents the gadget device to /sys/devices/virtual during unbind, clearing the gadget...

CVE-2026-43043

The CVE describes a Linux kernel vulnerability in the AF_ALG crypto interface where chaining a new af_alg_tsgl structure can leave the end marker of the previous Scatter/Gather List uncleared when a sendmsg exactly fills MAX_SGL_ENTS. This causes sg_next() to return NULL, potentially leading to a...
