CVE-2024-35950 is a use-after-free vulnerability in the Linux kernel DRM client subsystem. The DRM client modes[] array stores pointers to display modes held on connector mode lists. Those connector lists are protected by dev->mode_config.mutex, but modes[] was not consistently protected by the same mutex. Concurrent modification of a connector mode list could therefore free or reuse a mode object after its pointer had been retained in modes[], causing subsequent access through modes[] to dereference stale memory. The fix extends dev->mode_config.mutex protection to modes[].
