DEBIAN-CVE-2022-50036

In the Linux kernel, the following vulnerability has been resolved: drm/sun4i: dsi: Prevent underflow when computing packet sizes Currently, the packet overhead is subtracted using unsigned arithmetic. With a short sync pulse, this could underflow and wrap around to near the maximal u16 value. Fi...

CVE-2022-50188 drm/meson: Fix refcount leak in meson_encoder_hdmi_init

In the Linux kernel, the following vulnerability has been resolved: drm/meson: Fix refcount leak in mesonencoderhdmiinit offinddevicebynode takes reference, we should use putdevice to release it when not need anymore. Add missing putdevice in error path to avoid refcount leak...

CVE-2022-50188

CVE-2022-50188 is a Linux kernel vulnerability where a refcount leak in drm/meson was fixed. The issue arose because of how of_find_device_by_node() held a reference, with missing put_device() in the error path, leading to a refcount leak. The fix patches the kernel (meson_encoder_hdmi_init) to r...
