CyberRota Analysis
AI-GeneratedThe vulnerability affects the Linux kernel's radeon graphics driver, specifically in the `radeon_align_pitch()` function, which is susceptible to integer overflow during pitch alignment calculations. This can lead to the creation of invalid or zero-sized buffers in `radeon_mode_dumb_create()`, potentially causing system instability or crashes. Organizations using Linux systems with radeon graphics should prioritize addressing this vulnerability to ensure the stability and security of their environments.
Original NVD Description
In the Linux kernel, the following vulnerability has been resolved: drm/radeon: fix integer overflow in radeon_align_pitch() radeon_align_pitch() has the same kind of overflow issue as the old amdgpu helper: both the alignment round-up add and the final 'aligned * cpp' calculation can overflow signed int. If that wraps, radeon_mode_dumb_create() can end up returning an invalid pitch or creating a zero-sized dumb buffer. Fix this by using check_add_overflow() for the alignment round-up and check_mul_overflow() for the final pitch calculation, returning 0 on overflow. Also reject zero pitch and size in radeon_mode_dumb_create(). Found via AST-based call-graph analysis using sqry.
