CVE-2021-47279

CVE-2021-47279 affects the Linux kernel in the USB subsystem (usb: misc: brcmstb-usb-pinmap). The root cause is missing validation of the resource pointer returned by platform_get_resource(), which can lead to a null-ptr-deref. The vulnerability is resolved in the kernel by adding a check of the ...

CVE-2023-52806: NULL Pointer Dereference

In the Linux kernel, the following vulnerability has been resolved: ALSA: hda: Fix possible null-ptr-deref when assigning a stream While AudioDSP drivers assign streams exclusively of HOST or LINK type, nothing blocks a user to attempt to assign a COUPLED stream. As supplied substream instance ma...

CVE-2024-35874

A vulnerability was found in the Linux kernel that causes a NULL pointer dereference in the aiocomplete function during a wakeup operation. The issue arises because finishwait may skip locking if it encounters an empty list head. This leads to a NULL pointer dereference when attempting a wakeup...
