CVE-2026-23456

In the Linux kernel, the following vulnerability has been resolved:

netfilter: nf_conntrack_h323: fix OOB read in decode_int() CONS case

In decode_int(), the CONS case calls get_bits(bs, 2) to read a length

value, then calls get_uint(bs, len) without checking that len bytes

remain in the buffer. The existing boundary check only validates the

2 bits for get_bits(), not the subsequent 1-4 bytes that get_uint()

reads. This allows a malformed H.323/RAS packet to cause a 1-4 byte

slab-out-of-bounds read.

Add a boundary check for len bytes after get_bits() and before

get_uint().
