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-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-2026-98252

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-2026-98375

A flaw was found in the Linux kernel's Xen network frontend driver. This vulnerability allows a malicious host backend to cause a Denial of Service DoS by transmitting incoming network packets with an incomplete Ethernet header. Because the driver fails to verify that incoming packet buffers meet...

CVE-2026-98335

A flaw was found in the Linux kernel's mac80211 wireless networking subsystem. When a wireless interface disconnects from a mesh network while a channel switch announcement is in progress, the system releases the channel context without properly canceling the ongoing switch operation. A local use...

CVE-2026-98331

A flaw was found in the Linux kernel's mac80211 wireless networking subsystem. When a network namespace hosting a wireless device is destroyed, memory allocation failures during device migration can leave unregistered network interfaces in internal tracking lists. A local user can exploit this...

CVE-2026-98330

A flaw was found in the Linux kernel's cfg80211 wireless subsystem. When a network namespace is destroyed, the subsystem attempts to move wireless devices back to the default namespace, but a failure during the transfer can leave behind an invalid namespace reference. A local attacker can exploit...

CVE-2026-98314

A flaw was found in the Linux kernel's ALSA Advanced Linux Sound Architecture subsystem. A race condition during audio timer registration allows a new timer to become accessible to other processes before its internal data is initialized. A local user can exploit this vulnerability by concurrently...

CVE-2026-98220

A flaw was found in the Linux kernel's extensible scheduler schedext subsystem. This vulnerability allows a local privileged user to cause a Denial of Service DoS by triggering a kernel crash. When specific scheduler compatibility functions are invoked on tasks lacking an active scheduler, such a...

CVE-2026-98197

A flaw was found in the Linux kernel's w83791d hardware monitoring driver. This vulnerability allows a local user to cause a Denial of Service DoS by triggering a kernel crash. During driver removal, the driver fails to unregister optional sysfs interface files, leaving them accessible after the...

CVE-2026-98178

A flaw was found in the Linux kernel's AMD GPU driver. When compute subsystem initialization fails, uninitialized device structures remain attached to the graphics driver. A local user capable of triggering a GPU reset can cause the system to dereference an unallocated memory pointer, resulting i...

CVE-2026-98371

A flaw was found in the Linux kernel's IP Traffic Flow Security IP-TFS subsystem. Incomplete length validation when reassembling fragmented inner packets allows undersized packets to trigger an internal calculation underflow. A local user or remote attacker could exploit this vulnerability by...

Linux Distros Unpatched Vulnerability : CVE-2026-98268

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - perf: Fix null pointer access in isincludeguestevent A typical module unload occurring event when there is an active perf connection leads to freeing of the pmu...

CVE-2026-98358

A flaw was found in the Linux kernel's iSCSI Extensions for Remote Direct Memory Access iSER driver. A remote storage target can trigger a Denial of Service DoS by sending an unexpected remote invalidation response for write operations transmitted as immediate data. In this scenario, the initiato...
