In 0.9.10 and earlier, the TGA_INDEXED_RLE path selected by image_type == 9 allocates an image buffer using the one-byte-per-pixel SAIL_PIXEL_FORMAT_BPP8_INDEXED format returned by tga_private_sail_pixel_format() in src/sail-codecs/tga/helpers.c, while sail_codec_load_frame_v8_tga() in src/sail-codecs/tga/tga.c derives a two-to-four-byte pixel_size from an attacker-controlled header bpp value from 9 through 32. Loading a crafted color-mapped run-length-encoded TGA through sail_load_from_file() or sail_load_from_memory() therefore writes attacker-controlled bytes beyond the heap pixel buffer. The pixel-count clamp added for CVE-2026-40494 does not constrain the per-pixel write width, so this issue is an incomplete fix of that vulnerability and can cause heap corruption, a reliable crash, or potential code execution.
