CVE-2026-53037

A flaw was found in the Linux kernel's USB Human Interface Device HID subsystem. This vulnerability occurs when a USB device, containing both HID and storage or Universal Attached SCSI UAS components, is reset. During the reset process, memory allocation operations within the hidpostreset functio...

CVE-2026-52946

A flaw was found in the Linux kernel. A lock order deadlock can occur in the sendsigio and sendsigurg functions when a process group receives a signal. This vulnerability, caused by an unsafe lock order during software interrupts SOFTIRQ in asynchronous I/O fasync signaling, could allow a remote...

CVE-2026-53085

A flaw was found in the Linux kernel's Berkeley Packet Filter BPF subsystem. This use-after-free vulnerability occurs when the taskvma iterator reads task memory without properly acquiring a reference, allowing the memory structure to be freed concurrently while still in use. This can lead to...

CVE-2026-53106

A flaw was found in the Linux kernel's Berkeley Packet Filter BPF local storage. This vulnerability can lead to a system deadlock when local storage is deleted within a Non-Maskable Interrupt NMI context. An attacker could potentially exploit this by triggering the deletion of BPF local storage...

CVE-2026-53197

A flaw was found in the iptfs module of the Linux kernel. This issue, an ABBA deadlock, occurs when iptfsdestroystate attempts to cancel a timer while holding a spinlock that the timer's callback also tries to acquire. This circular dependency can cause the system to become unresponsive, leading ...

CVE-2026-53166

A flaw was found in the Linux kernel's futex Fast Userspace Mutex requeue mechanism. When a non-top waiter attempts to requeue a Priority Inheritance PI futex it already owns, a NULL pointer dereference can occur. This issue, specifically within the removewaiter function during a self-deadlock...

CVE-2026-53207

A flaw was found in the Linux kernel's memory management, specifically concerning huge pages. When two concurrent memory poisoning operations madviseMADVHWPOISON occur on the same huge page while it is also being unmapped, a recursive spinlock self-deadlock can be triggered. This can lead to a...
