Guard the division against a zero tile_cols by\ninitialising the context-update values to zero and computing them only\nwhen tile_cols is non-zero, and stop the descriptor writes once the\ntile_info buffer is full. The tile geometry written to the hardware\nregisters is left unmodified; the per-dimension and total tile bounds are\nenforced by the control validation.","cvssScore":7.8,"cvssSeverity":"HIGH","cvssVector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","cwes":[],"vendors":[],"products":[],"references":[{"url":"https://git.kernel.org/stable/c/6b7a281a815ae7c5e7bb2aad039ffea9bc933157","tags":[]},{"url":"https://git.kernel.org/stable/c/7baa7bb1b784c19170df8c99466fa412040eb431","tags":[]},{"url":"https://git.kernel.org/stable/c/8f19d869a9f6800547c9ad7ebaf3b94f973dab50","tags":[]},{"url":"https://git.kernel.org/stable/c/b84f6533a8ed2fd7b282fc7ab4b8efadc745a89c","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
