一、漏洞信息
 漏洞编号：[CVE-2021-47015](https://nvd.nist.gov/vuln/detail/CVE-2021-47015)
 漏洞归属组件：[kernel](https://gitee.com/src-openeuler/kernel)
 漏洞归属的版本：4.19.140,4.19.194,4.19.90,5.10.0,6.1.0,6.1.14,6.1.19,6.1.5,6.1.6,6.1.8,6.4.0
 CVSS V2.0分值：
  BaseScore：0.0 Low
  Vector：CVSS：2.0/
 漏洞简述：
  In the Linux kernel, the following vulnerability has been resolved:bnxt_en: Fix RX consumer index logic in the error path.In bnxt_rx_pkt(), the RX buffers are expected to complete in order.If the RX consumer index indicates an out of order buffer completion,it means we are hitting a hardware bug and the driver will abort allremaining RX packets and reset the RX ring.  The RX consumer indexthat we pass to bnxt_discard_rx() is not correct.  We should bepassing the current index (tmp_raw_cons) instead of the old index(raw_cons).  This bug can cause us to be at the wrong index whentrying to abort the next RX packet.  It can crash like this: #0 [ffff9bbcdf5c39a8] machine_kexec at ffffffff9b05e007 #1 [ffff9bbcdf5c3a00] __crash_kexec at ffffffff9b111232 #2 [ffff9bbcdf5c3ad0] panic at ffffffff9b07d61e #3 [ffff9bbcdf5c3b50] oops_end at ffffffff9b030978 #4 [ffff9bbcdf5c3b78] no_context at ffffffff9b06aaf0 #5 [ffff9bbcdf5c3bd8] __bad_area_nosemaphore at ffffffff9b06ae2e #6 [ffff9bbcdf5c3c28] bad_area_nosemaphore at ffffffff9b06af24 #7 [ffff9bbcdf5c3c38] __do_page_fault at ffffffff9b06b67e #8 [ffff9bbcdf5c3cb0] do_page_fault at ffffffff9b06bb12 #9 [ffff9bbcdf5c3ce0] page_fault at ffffffff9bc015c5    [exception RIP: bnxt_rx_pkt+237]    RIP: ffffffffc0259cdd  RSP: ffff9bbcdf5c3d98  RFLAGS: 00010213    RAX: 000000005dd8097f  RBX: ffff9ba4cb11b7e0  RCX: ffffa923cf6e9000    RDX: 0000000000000fff  RSI: 0000000000000627  RDI: 0000000000001000    RBP: ffff9bbcdf5c3e60   R8: 0000000000420003   R9: 000000000000020d    R10: ffffa923cf6ec138  R11: ffff9bbcdf5c3e83  R12: ffff9ba4d6f928c0    R13: ffff9ba4cac28080  R14: ffff9ba4cb11b7f0  R15: ffff9ba4d5a30000    ORIG_RAX: ffffffffffffffff  CS: 0010  SS: 0018

CVE-2021-47015

影响性分析说明：
In the Linux kernel, the following vulnerability has been resolved:

bnxt_en: Fix RX consumer index logic in the error path.

In bnxt_rx_pkt(), the RX buffers are expected to complete in order.
If the RX consumer index indicates an out of order buffer completion,
it means we are hitting a hardware bug and the driver will abort all
remaining RX packets and reset the RX ring.  The RX consumer index
that we pass to bnxt_discard_rx() is not correct.  We should be
passing the current index (tmp_raw_cons) instead of the old index
(raw_cons).  This bug can cause us to be at the wrong index when
trying to abort the next RX packet.  It can crash like this:
