A local user can exploit this vulnerability through repeated BPF operations, causing an unbounde...

CVE-2026-80764

A flaw was found in the Linux kernel's Bluetooth subsystem. A local user could exploit a use-after-free vulnerability in the hcievent component. This occurs when the hciccreset function clears Bluetooth Low Energy LE lists without proper locking, allowing a debugfs reader to access freed memory...

CVE-2026-98849

A flaw was found in the Linux kernel's Packet Forwarding Control Protocol PFCP driver. When creating a PFCP network interface, a failure during device registration triggers error handling that attempts to release an internal network socket twice. This improper cleanup results in a null pointer...

CVE-2026-98848

A flaw was found in the Linux kernel's AC100 Real-Time Clock RTC driver. During device probing, the driver accesses an internal array before initializing its element counter. On systems compiled with runtime bounds checking enabled, this premature access triggers an out-of-bounds trap, allowing a...

CVE-2026-98787

A flaw was found in the Linux kernel's Berkeley Packet Filter BPF subsystem. Missing CPU migration protection during batch lookup and delete operations on hash tables allows a task to migrate between processors while freeing memory. A local attacker could exploit this condition to trigger a kerne...

CVE-2026-98785

A flaw was found in the Linux kernel's AMD display driver. During power management suspend operations under low memory conditions, the driver fails to handle memory allocation failures and retains an invalid null state. When the system subsequently attempts to resume or recover the graphics...

CVE-2026-98786

A flaw was found in the Linux kernel's AMD GPU display driver. During DisplayPort Multi-Stream Transport MST display disconnection, a race condition can cause the driver to access display data structures without verifying that they remain valid. A local user or physically proximate attacker...

CVE-2026-98783

A flaw was found in the Linux kernel's MediaTek DRM Direct Rendering Manager driver. The driver fails to verify whether the display overlay adaptor platform device is successfully registered during initialization. If the registration fails, the system attempts to use an invalid memory pointer,...

CVE-2026-98778

A flaw was found in the Linux kernel's Android Binder driver. This vulnerability allows a local user to cause a Denial of Service DoS or application disruption by triggering the unexpected closure of unrelated file descriptors in a target process. When an asynchronous transaction update supersede...
