The vulnerability of the garp_pdu_parse_attr() function in the net/802/garp.c module, which is part of the networking functions in the Linux kernel, allows a hacker to cause a service failure.

The vulnerability of the garppduparseattr function in the net/802/garp.c module, which is part of the networking functions in the Linux kernel, relates to the possibility of integer overflow. Exploiting this vulnerability could allow an attacker to cause a service failure...

CVE-2026-63868 net: garp: fix unsigned integer underflow in garp_pdu_parse_attr

In the Linux kernel, the following vulnerability has been resolved: net: garp: fix unsigned integer underflow in garppduparseattr The receive-side GARP attribute parser computes dlen with reversed operands: dlen = sizeofga - ga-len; ga-len is the on-wire attribute length and includes the GARP...
