CVE-2026-63891

A flaw was found in the Linux kernel's Thunderbolt property parsing. An untrusted Thunderbolt peer, such as a cable or dock, can send specially crafted property requests that create a recursive loop. This can lead to kernel stack exhaustion, resulting in a system crash and a Denial of Service DoS...

CVE-2026-64017

A flaw was found in the Linux kernel's blk-mq component. This use-after-free vulnerability occurs when a task attempts to submit a bio a data structure for I/O operations to blk-mq. If the task is interrupted and sleeps after checking for a cached request but before using it, the cached request c...

CVE-2026-63930

A flaw was found in the Linux kernel's Industrial I/O IIO hardware consumer buffer component. This use-after-free vulnerability occurs in the errputbuffers cleanup path of iiohwconsumeralloc. During buffer cleanup, the code incorrectly uses listforeachentry to iterate through buffers while...

CVE-2026-63933

A flaw was found in the Linux kernel's adis16260 gyroscope driver. A local user can trigger a division-by-zero error by writing a zero value to the samplingfrequency sysfs attribute. This can lead to a kernel panic, resulting in a system crash and a Denial of Service DoS...

CVE-2026-63881

A flaw was found in the Linux kernel's AMD KFD Kernel Fusion Driver debugger component. The getqueueids function, responsible for handling queue identifiers, contains an integer overflow vulnerability. This occurs when calculating the size of an array, where a malicious local user could provide a...

CVE-2026-63905

A flaw was found in the Linux kernel's USB/IP Virtual USB Device Controller vudc component. A race condition exists in the vudcremove function, which can lead to a use-after-free vulnerability. This occurs when the system attempts to free a data structure while a timer within it is still active o...

CVE-2026-63915

A flaw was found in the Linux kernel's Near Field Communication NFC Host Controller Interface HCI. A remote attacker, by sending a specially crafted 0-byte Host Controller Protocol HCP frame, could trigger an out-of-bounds read. This could lead to a system crash, resulting in a Denial of Service...

CVE-2026-64008

A flaw was found in the accel/rocket component of the Linux kernel. This vulnerability, a Use-After-Free UAF, occurs in the rocketioctlcreatebo function. A local attacker could exploit this by triggering a failure in subsequent operations after a Graphics Execution Manager GEM handle is created,...

CVE-2026-63929

A flaw was found in the Linux kernel's Industrial I/O iio buffer component. The iiobufferenqueuedmabuf function, responsible for managing Direct Memory Access DMA buffers, fails to properly release a memory reference. This oversight results in a continuous memory leak, where small blocks of memor...

CVE-2026-64019

A flaw was found in the Linux kernel's NVMe Non-Volatile Memory Express PCI Peripheral Component Interconnect driver. This vulnerability occurs due to a leak in the Direct Memory Access DMA mapping during data setup operations. Specifically, the system fails to properly unmap DMA resources when...
