Descripción
*** Pendiente de traducción *** 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->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->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.
