CVE-2026-31784

A flaw was found in the Linux kernel's drm/xe/pxp component. An issue exists where a restart flag in the pxpstart function is not properly cleared. This oversight can cause the function to continuously loop, potentially leading to a system hang or crash, resulting in a Denial of Service DoS...

CVE-2026-31770

A flaw was found in the Linux kernel's hwmon subsystem, specifically within the occ driver. During early boot or when no sensor samples have been collected, the occshowpower1 function can attempt to divide by zero. A local attacker could exploit this condition, leading to a kernel crash and a...

CVE-2026-31757

A flaw was found in the Linux kernel. Specifically, within the USB subsystem usbio, a memory leak occurs when a Universal Serial Bus USB Request Block URB submission fails during the device probing process. This failure to free the allocated URB memory can lead to a gradual depletion of system...

CVE-2026-31754

A flaw was found in the Linux kernel's USB subsystem, specifically within the cdns3 gadget driver. A local user could exploit this vulnerability by attempting to switch the USB role to host mode after a gadget initialization failure. This state inconsistency can lead to a system crash, resulting ...

CVE-2026-31749

A flaw was found in the niatmio16d driver within the Comedi Comedi is a collection of drivers for data acquisition equipment subsystem of the Linux kernel. This vulnerability occurs when an error during the driver's attach process causes the cleanup function atmio16ddetach to be called with...

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-2026-31703

A flaw was found in the Linux kernel. A use-after-free vulnerability exists in the inodeswitchwbsworkfn function, part of the kernel's writeback subsystem. This issue arises when a work item remains active after its associated memory object wb has been released, leading to system instability. An...

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-2026-43036

A flaw was found in the Linux kernel's networking subsystem. An attacker injecting specially crafted packets through PFPACKET paths could trigger an uninitialized value read when processing TCPv4 Generic Segmentation Offload GSO packets. This vulnerability, specifically in the gsofeaturescheck...

CVE-2026-43022

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: hcisync: hcicmdsyncqueueonce return -EEXIST if exists hcicmdsyncqueueonce needs to indicate whether a queue item was added, so caller can know if callbacks are called, so it can avoid leaking resources. Change the...

CVE-2026-31771
