Description
A flaw was found in the Linux kernel's drm/komeda component, specifically within the AFBC framebuffer size validation. An integer overflow occurs when calculating the required buffer size, which could allow a local attacker to provide an undersized graphics memory object. This can lead to out-of-bounds memory access, potentially causing system instability or unauthorized data manipulation.
