CVE-2025-38619

What it is

In the Linux kernel, the following vulnerability has been resolved: media: ti: j721e-csi2rx: fix list_del corruption If ti_csi2rx_start_dma() fails in ti_csi2rx_dma_callback(), the buffer is marked done with VB2_BUF_STATE_ERROR but is not removed from the DMA queue. This causes the same buffer to be retried in the next iteration, resulting in a double list_del() and eventual list corruption. Fix this by removing the buffer from the queue before calling vb2_buffer_done() on error. This resolves a crash due to list_del corruption: [ 37.811243] j721e-csi2rx 30102000.ticsi2rx: Failed to queue the next buffer for DMA [ 37.832187] slab kmalloc-2k start ffff00000255b000 pointer offset 1064 size 2048 [ 37.839761] list_del corruption. next->prev should be ffff00000255bc28, but was ffff00000255d428.
