  3. CVE-2026-43256
In the Linux kernel, the following vulnerability has been resolved: media: qcom: camss: vfe: Fix out-of-bounds access in vfe_isr_reg_update() vfe_isr() iterates using MSM_VFE_IMAGE_MASTERS_NUM(7) as the loop bound and passes the index to vfe_isr_reg_update(). However, vfe->line[] array is defined with VFE_LINE_NUM_MAX(4): struct vfe_line line[VFE_LINE_NUM_MAX]; When index is 4, 5, 6, the access to vfe->line[line_id] exceeds the array bounds and resulting in out-of-bounds memory access. Fix this by using separate loops for output lines and write masters.

Summary
  • (es) En el kernel de Linux, la siguiente vulnerabilidad ha sido resuelta: media: qcom: camss: vfe: Corrección de acceso fuera de límites en vfe_isr_reg_update() vfe_isr() itera utilizando MSM_VFE_IMAGE_MASTERS_NUM(7) como límite del bucle y pasa el índice a vfe_isr_reg_update(). Sin embargo, el array vfe -> line[] está definido con VFE_LINE_NUM_MAX(4): struct vfe_line line[VFE_LINE_NUM_MAX]; Cuando el índice es 4, 5, 6, el acceso a vfe -> line[line_id] excede los límites del array y resulta en un acceso a memoria fuera de límites. Esto se soluciona utilizando bucles separados para líneas de salida y maestros de escritura.
