CVE-2026-89879

This Linux kernel vulnerability affects the s2255 media driver. In s2255_fillbuff(), a memcpy() copies vc->jpg_size bytes of a captured JPEG/MJPEG frame into a vb2 plane, but the size value is taken verbatim from the device's S2255_MARKER_FRAME header without being bounded against the destinat...

In the Linux kernel, the following vulnerability has been resolved: media: s2255: check firmware size before reading trailing marker s2255probe reads a 4-byte marker and version from the last 8 bytes of the firmware blob fw-datafwsize - 8 and fwsize - 4. If the firmware file is shorter than 8...

CVE-2026-89878

CVE-2026-89878 affects the Linux kernel media: s2255 driver. In s2255_probe(), the function reads a 4-byte marker and version from the last 8 bytes of the firmware blob (fw->data[fw_size - 8] and [fw_size - 4]). If the firmware file is shorter than 8 bytes, fw_size - 8 underflows , causing an ...
