"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nbnxt_en: Fix RX consumer index logic in the error path.\n\nIn bnxt_rx_pkt(), the RX buffers are expected to complete in order.\nIf the RX consumer index indicates an out of order buffer completion,\nit means we are hitting a hardware bug and the driver will abort all\nremaining RX packets and reset the RX ring. The RX consumer index\nthat we pass to bnxt_discard_rx() is not correct. We should be\npassing the current index (tmp_raw_cons) instead of the old index\n(raw_cons). This bug can cause us to be at the wrong index when\ntrying to abort the next RX packet. It can crash like this:\n\n #0 [ffff9bbcdf5c39a8] machine_kexec at ffffffff9b05e007\n #1 [ffff9bbcdf5c3a00] __crash_kexec at ffffffff9b111232\n #2 [ffff9bbcdf5c3ad0] panic at ffffffff9b07d61e\n #3 [ffff9bbcdf5c3b50] oops_end at ffffffff9b030978\n #4 [ffff9bbcdf5c3b78] no_context at ffffffff9b06aaf0\n #5 [ffff9bbcdf5c3bd8] __bad_area_nosemaphore at ffffffff9b06ae2e\n #6 [ffff9bbcdf5c3c28] bad_area_nosemaphore at ffffffff9b06af24\n #7 [ffff9bbcdf5c3c38] __do_page_fault at ffffffff9b06b67e\n #8 [ffff9bbcdf5c3cb0] do_page_fault at ffffffff9b06bb12\n #9 [ffff9bbcdf5c3ce0] page_fault at ffffffff9bc015c5\n [exception RIP: bnxt_rx_pkt+237]\n RIP: ffffffffc0259cdd RSP: ffff9bbcdf5c3d98 RFLAGS: 00010213\n RAX: 000000005dd8097f RBX: ffff9ba4cb11b7e0 RCX: ffffa923cf6e9000\n RDX: 0000000000000fff RSI: 0000000000000627 RDI: 0000000000001000\n RBP: ffff9bbcdf5c3e60 R8: 0000000000420003 R9: 000000000000020d\n R10: ffffa923cf6ec138 R11: ffff9bbcdf5c3e83 R12: ffff9ba4d6f928c0\n R13: ffff9ba4cac28080 R14: ffff9ba4cb11b7f0 R15: ffff9ba4d5a30000\n ORIG_RAX: ffffffffffffffff CS: 0010 SS: 0018"
