CVE-2026-43297 Details
Description
In the Linux kernel, the following vulnerability has been resolved: media: rockchip: rga: Fix possible ERR_PTR dereference in rga_buf_init() rga_get_frame() can return ERR_PTR(-EINVAL) when buffer type is unsupported or invalid. rga_buf_init() does not check the return value and unconditionally dereferences the pointer when accessing f->size. Add proper ERR_PTR checking and return the error to prevent dereferencing an invalid pointer.
A vulnerability exists in the Linux kernel's handling of media buffers for Rockchip's RGA (Raster Graphics Accelerator) component. The issue arises in the buffer initialization function, rga_buf_init(), which fails to properly validate the return value of rga_get_frame(). This function can return an error pointer indicating an invalid or unsupported buffer type. The lack of validation leads to an unintentional dereference of the pointer, potentially causing a crash or other unintended behavior. This vulnerability affects several versions of the Linux kernel.
Users can upgrade to the latest version of the Linux kernel where this vulnerability has been addressed. Instructions for upgrading the kernel can be found in the official Linux kernel documentation.
