{"id":"DEBIAN-CVE-2021-47015","details":"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:   #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","modified":"2026-09-15T09:02:30.674487950Z","published":"2024-02-28T09:15:38.913Z","upstream":["CVE-2021-47015"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2021-47015"}],"affected":[{"package":{"name":"linux","ecosystem":"Debian:12","purl":"pkg:deb/debian/linux?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"5.10.38-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2021-47015.json"}},{"package":{"name":"linux","ecosystem":"Debian:13","purl":"pkg:deb/debian/linux?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"5.10.38-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2021-47015.json"}},{"package":{"name":"linux","ecosystem":"Debian:14","purl":"pkg:deb/debian/linux?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"5.10.38-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2021-47015.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"}]}
