CVE-2026-23456

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> netfilter: nf_conntrack_h323: fix OOB read in decode_int() CONS case<br /> <br /> In decode_int(), the CONS case calls get_bits(bs, 2) to read a length<br /> value, then calls get_uint(bs, len) without checking that len bytes<br /> remain in the buffer. The existing boundary check only validates the<br /> 2 bits for get_bits(), not the subsequent 1-4 bytes that get_uint()<br /> reads. This allows a malformed H.323/RAS packet to cause a 1-4 byte<br /> slab-out-of-bounds read.<br /> <br /> Add a boundary check for len bytes after get_bits() and before<br /> get_uint().
