CVE-2026-98419

A flaw was found in the Linux kernel's dropmonitor subsystem. An incorrect buffer size calculation during per-CPU data resets leads to an out-of-bounds write when clearing memory. A local user could exploit this vulnerability to corrupt kernel memory, resulting in a system crash and Denial of...

CVE-2026-98418

A flaw was found in the Linux kernel's process scheduler. A local user can cause a Denial of Service DoS by initiating lock contention across processor cores with a task that has processor migration disabled. In this scenario, the scheduler incorrectly triggers a kernel warning when moving the...

CVE-2026-98414

A flaw was found in the Linux kernel. An issue in the memory control group memcg subsystem occurs when memory allocated within a child control group is transferred to the root group upon group deletion. Subsequent memory reclamation improperly charges pages to the root group without ever unchargi...

CVE-2026-98413

A flaw was found in the Linux kernel's SELinux Security-Enhanced Linux subsystem. When an access check is performed with an empty permission set, the Access Vector Cache AVC fails to initialize the access decision structure before returning. A local attacker can exploit this flaw by triggering...

CVE-2026-98416

A flaw was found in the Linux kernel's Texas Instruments K3 UDMA Unified Direct Memory Access driver. This vulnerability can lead to a Denial of Service DoS caused by a null pointer dereference when freeing resources during a failed channel request. Under resource-exhaustion conditions, the...

CVE-2026-98412

A flaw was found in the Linux kernel's power sequencing subsystem. If a memory allocation failure occurs while setting up dependencies in pwrsequnitsetupdeps, error handling cleans up the partially allocated unit without having initialized its internal list. This uninitialized state leads to a NU...

CVE-2026-98411

A flaw was found in the Linux kernel's power sequencing subsystem. When device registration encounters a naming failure, the error-handling path attempts to clean up data structures before they are initialized. This issue leads to an invalid pointer dereference, which can cause the kernel to cras...

CVE-2026-23111-PoC

CVE-2026-23111exploit CVE-2026-23111 — Linux Kernel nftables UAF → LPE A working local-privilege-escalation exploit for CVE-2026-23111 , a use-after-free in the Linux kernel nftables subsystem. Tested on linux-6.12.69 x86-64. Target requirements The exploit assumes a target kernel built with:...

CVE-2026-98406

A flaw was found in the Linux kernel's mac80211 wireless subsystem. A local attacker can trigger a denial of service DoS condition by issuing a wireless bitrate configuration request while a network interface is undergoing initialization or teardown. Because the subsystem fails to verify that the...

CVE-2026-98410

A flaw was found in the Linux kernel's DA9063 watchdog driver. When a system suspends while the hardware watchdog timer is running without active user-space management, the driver fails to disable the timer. Consequently, the timer continues to run and can expire while the system is suspended,...

CVE-2026-98409

A flaw was found in the Linux kernel's Realtek RTD119X watchdog driver. During device initialization, the driver fails to verify that the clock rate is valid before performing timeout calculations. A local user capable of triggering device probing under misconfigured clock conditions can cause a...

CVE-2026-98408

A flaw was found in the Linux kernel's Renesas RZ/V2H watchdog timer driver. The driver fails to validate that the clock rate is non-zero during device initialization, leading to a division by zero condition. Under specific hardware or configuration states where the clock rate is zero, this issue...

CVE-2026-98407

A flaw was found in the Linux kernel's Redpine Signals Inc. rsi wireless driver. An incorrect memory offset calculation during encryption key removal causes data to be written past the allocated buffer, corrupting kernel heap memory. This issue is triggered during routine wireless events such as...

CVE-2026-98405

A flaw was found in the Linux kernel's SMB Server Message Block client. When parsing POSIX security identifiers in server responses, the client fails to properly validate the server-supplied buffer length against the actual received message boundaries. A malicious or compromised SMB server could...

CVE-2021-3493
