Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> media: qcom: camss: vfe: Fix out-of-bounds access in vfe_isr_reg_update()<br /> <br /> vfe_isr() iterates using MSM_VFE_IMAGE_MASTERS_NUM(7) as the loop<br /> bound and passes the index to vfe_isr_reg_update(). However,<br /> vfe-&gt;line[] array is defined with VFE_LINE_NUM_MAX(4):<br /> <br /> struct vfe_line line[VFE_LINE_NUM_MAX];<br /> <br /> When index is 4, 5, 6, the access to vfe-&gt;line[line_id] exceeds<br /> the array bounds and resulting in out-of-bounds memory access.<br /> <br /> Fix this by using separate loops for output lines and write masters.
