Summary

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!
