drm/exec: don't immediately add prelocked obj to array of locked objs In the Linux kernel, the following vulnerability has been resolved:\ndrm/exec: don't immediately add prelocked obj to array of locked objs\nWhen a contention is detected the drm_exec object grabs a reference tothe contended object, unlocks all other objects and pre-locks thecontended one before anything else.\nThe problem is that it is possible that this pre-locked object was aboutto be destroyed and drm_exec is now holding the last reference to it.\nSo we never actually see this pre-locked object again to be explicitlylocked and so also never reserve a slot for a dma_fence object on it.\nShould the driver now use drm_exec_for_each_locked_object() to add a newfence to all locked objects we eventually see a warning or even aBUG_ON() to prevent random memory corruption.\nFix this by keeping the prelocked object out of the array of locked objsuntil it was explicitly mentioned by the driver again.\nIf the prelocked object is never mentioned again by the driverjust unlock and drop the reference at the end of the locking loop.\nhttps://www.cve.org/CVERecord?id=CVE-2026-99147https://git.kernel.org/stable/c/96d9996e5dbcfabed052c0d9377a382c95fed607https://git.kernel.org/stable/c/7a10cd79c4d9a90334fece32fef3a8e5b1a9727bhttps://git.kernel.org/stable/c/26401a4999f1596a515b2e704e7066ac09306488#kernel
