CVE-2026-68128

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> ice: reject out-of-range ptype in ice_parser_profile_init<br /> <br /> set_bit(rslt-&gt;ptype, prof-&gt;ptypes) operates on a DECLARE_BITMAP of<br /> ICE_FLOW_PTYPE_MAX (1024) bits. Nothing prevents a malicious VF from<br /> providing ptype &gt;= 1024 through VIRTCHNL, resulting in a write past<br /> the end of the bitmap and a kernel page fault.<br /> <br /> Reproduced with a custom kernel module injecting a crafted<br /> VIRTCHNL_OP_ADD_RSS_CFG on E810-C QSFP (8086:1592),<br /> FW 4.91 0x800214af 1.3909.0, ICE COMMS DDP 1.3.53.0,<br /> kernel 7.1.0-rc1.<br /> <br /> crash_parser: ice_parser_profile_init @ ffffffffc0d61b60<br /> crash_parser: setting ptype=0xffff (max valid=1023)<br /> crash_parser: calling ice_parser_profile_init -- expect OOB crash!<br /> BUG: kernel NULL pointer dereference, address: 0000000000000000<br /> Oops: Oops: 0002 [#1] SMP NOPTI<br /> CPU: 56 UID: 0 PID: 165011 Comm: insmod Kdump: loaded Tainted: G S U OE 7.1.0-rc1 #1<br /> Hardware name: Intel Corporation S2600BPB/S2600BPB<br /> RIP: 0010:ice_parser_profile_init+0x2d/0x1d0 [ice]<br /> Call Trace:<br /> <br /> ? __pfx_ice_parser_profile_init+0x10/0x10 [ice]<br /> crash_init+0x127/0xff0 [crash_parser]<br /> do_one_initcall+0x45/0x310<br /> do_init_module+0x64/0x270<br /> init_module_from_file+0xcc/0xf0<br /> idempotent_init_module+0x17b/0x280<br /> __x64_sys_finit_module+0x6e/0xe0<br /> <br /> Bail out early with -EINVAL when ptype is out of range.
