CVE-2026-31405

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> media: dvb-net: fix OOB access in ULE extension header tables<br /> <br /> The ule_mandatory_ext_handlers[] and ule_optional_ext_handlers[] tables<br /> in handle_one_ule_extension() are declared with 255 elements (valid<br /> indices 0-254), but the index htype is derived from network-controlled<br /> data as (ule_sndu_type &amp; 0x00FF), giving a range of 0-255. When<br /> htype equals 255, an out-of-bounds read occurs on the function pointer<br /> table, and the OOB value may be called as a function pointer.<br /> <br /> Add a bounds check on htype against the array size before either table<br /> is accessed. Out-of-range values now cause the SNDU to be discarded.
