CVE-2026-68128
8.8 · HIGHOverview
CVE-2026-68128 is a high-severity vulnerability. It was published on August 10, 2026 and has a CVSS 3.1 base score of 8.8 (HIGH).
This vulnerability has a CVSS 3.1 base score of 8.8, rated HIGH. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.
Technical Description
In the Linux kernel, the following vulnerability has been resolved:
ice: reject out-of-range ptype in ice_parser_profile_init
set_bit(rslt->ptype, prof->ptypes) operates on a DECLARE_BITMAP of
ICE_FLOW_PTYPE_MAX (1024) bits. Nothing prevents a malicious VF from
providing ptype >= 1024 through VIRTCHNL, resulting in a write past
the end of the bitmap and a kernel page fault.
Reproduced with a custom kernel module injecting a crafted
VIRTCHNL_OP_ADD_RSS_CFG on E810-C QSFP (8086:1592),
FW 4.91 0x800214af 1.3909.0, ICE COMMS DDP 1.3.53.0,
kernel 7.1.0-rc1.
crash_parser: ice_parser_profile_init @ ffffffffc0d61b60
crash_parser: setting ptype=0xffff (max valid=1023)
crash_parser: calling ice_parser_profile_init -- expect OOB crash!
BUG: kernel NULL pointer dereference, address: 0000000000000000
Oops: Oops: 0002 [#1] SMP NOPTI
CPU: 56 UID: 0 PID: 165011 Comm: insmod Kdump: loaded Tainted: G S U OE 7.1.0-rc1 #1
Hardware name: Intel Corporation S2600BPB/S2600BPB
