CVE-2026-64050 in Linux
요약
\~에 의해 MITRE • 2026. 07. 19.
In the Linux kernel, the following vulnerability has been resolved:
drm/msm/dpu: don't mix devm and drmm functions
Mixing devm and drmm functions will result in a use-after-free on msm driver teardown if userspace keeps a reference on the drm device: The WB connector data will be destroyed because of the use of devm_kzalloc()), while the usersoace still can try interacting with the WB connector (which uses drmm_ functions).
Change dpu_writeback_init() to use drmm_.
