In the Linux kernel, the following vulnerability has been resolved:<\/p>\n
drm\/radeon: fix integer overflow in radeon_align_pitch()<\/p>\n
radeon_align_pitch() has the same kind of overflow issue as the old
\namdgpu helper: both the alignment round-up add and the final
\n‘aligned * cpp’ calculation can overflow signed int.<\/p>\n
If that wraps, radeon_mode_dumb_create() can end up returning an
\ninvalid pitch or creating a zero-sized dumb buffer.<\/p>\n
Fix this by using check_add_overflow() for the alignment round-up and
\ncheck_mul_overflow() for the final pitch calculation, returning 0 on
\noverflow. Also reject zero pitch and size in
\nradeon_mode_dumb_create().<\/p>\n
