been resolved:\n\ndrm/komeda: fix integer overflow in AFBC framebuffer size check\n\nThe AFBC framebuffer size validation calculates the minimum required\nbuffer size by adding the AFBC payload size to the framebuffer offset.\nThis addition is performed without checking for integer overflow.\n\nIf the addition oveflows, the size check may incorrectly succed and\nallow userspace to provide an undersized drm_gem_object, potentially\nleading to out-of-bounds memory access.\n\nAdd usage of check_add_overflow() to safely compute the minimum\nrequired size and reject the framebuffer if an overflow is detected.\nThis makes the AFBC size validation more robust against malformed.\n\nFound by Linux Verification Center (linuxtesting.org) with SVACE."}], "affected": [{"product": "Linux",
