CVE-2026-98268

A flaw was found in the Linux kernel's performance monitoring perf subsystem. This vulnerability allows a local user to cause a Denial of Service DoS by crashing the operating system. When a kernel module is unloaded while a performance event remains active, the kernel clears the associated...

CVE-2026-98267

A flaw was found in the Linux kernel's 9P file system implementation. When write operations extend a file, the kernel fails to update the recorded file size to reflect the new length. A local user performing write operations on a 9P mount can trigger this issue, leading to inconsistent file state...

CVE-2026-98266

A flaw was found in the Linux kernel's Advanced Linux Sound Architecture ALSA subsystem. When an audio card is released asynchronously, such as during the disconnection of a USB sound device, active background tasks may continue accessing the device structure after it has been deallocated due to...

CVE-2026-98264

A flaw was found in the Advanced Linux Sound Architecture ALSA virtio sound driver in the Linux kernel. During device removal or system suspend operations, virtual queues are deleted before the virtual device is reset, allowing the device to access queue memory buffers after they have been freed...

CVE-2025-38352-PoC

CVE-2025-38352: Linux Kernel POSIX CPU Timer TOCTOU Race Condition & UAF A reproducible Proof-of-Concept PoC and automated GDB orchestration script for CVE-2025-38352 , a Time-of-Check to Time-of-Use TOCTOU race condition in the Linux kernel's POSIX CPU timer subsystem...

CVE-2026-98263

A flaw was found in the Linux kernel's Realtek RT712 audio codec driver. A local user could exploit this flaw to cause a Denial of Service DoS or unexpected system behavior. The issue arises because audio stream configuration data is left uninitialized before being passed to the SoundWire...

CVE-2026-98261

A flaw was found in the Linux kernel's Common Internet File System CIFS client. When a secondary communication channel is disabled or no longer supported by a remote file server, the client releases session structures from memory while continuing to access them. A malicious server can exploit thi...

CVE-2026-98260

A flaw was found in the Linux kernel. When a multi-threaded program sets up a per-thread timer and executes a new program that subsequently fails during startup, the kernel can free timer memory while it remains referenced in an active queue. A local user could exploit this vulnerability to trigg...

CVE-2026-98259

A flaw was found in the Linux kernel. A local user could exploit this vulnerability to cause a Denial of Service DoS by crashing the system. In the Direct Access DAX subsystem, the kernel fails to verify whether storage entries are zero or empty before converting them, leading to an invalid memor...

CVE-2026-98258

A flaw was found in the Linux kernel's POSIX CPU timer subsystem. A race condition can occur when modifying or deleting a timer concurrently with its expiration handling, allowing the timer to be freed while still queued on an active expiry list. A local user could exploit this use-after-free UAF...

CVE-2026-98257

A flaw was found in the Linux kernel's Reliable Datagram Sockets RDS subsystem. A remote attacker can trigger a Denial of Service DoS by negotiating an incompatible protocol version during connection establishment. This mismatch causes the kernel to attempt a synchronous connection teardown while...

CVE-2026-98256

A flaw was found in the Linux kernel's signal handling subsystem. A race condition occurs during process execution when managing pending timer signals, allowing the system to reference memory after it has been released. A local attacker could exploit this use-after-free flaw to achieve privilege...

CVE-2026-98254

A flaw was found in the Linux kernel's Software I/O Translation Lookaside Buffer swiotlb. During Direct Memory Access DMA bounce operations involving high memory, an incorrect address calculation occurs when an offset crosses a page boundary. This error causes data transfers to read from or...

CVE-2026-98252

A flaw was found in the Linux kernel's Remote Direct Memory Access RDMA subsystem. This flaw allows a local attacker to cause a denial of service DoS due to a race condition in the iWARP port mapper component. Because request structures are added to a shared tracking list before their reference...

CVE-2026-98251

A flaw was found in the Linux kernel's Open vSwitch component. When handling network connection tracking conntrack labels, the kernel may reallocate memory for active connections while another processor accesses it simultaneously. This race condition can lead to memory corruption, allowing an...
