ice: copy last block omitted in ice_get_module_eeprom()

Noroxi assessment

Priority: Monitor (action score 31/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.21% (FIRST EPSS).
  • Someone with local access to the system can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: Linux Linux 84cba1840e68430325ac133a11be06bfb2f7acd8, 8cfbdda65588e75bfbd93e5ee847efcb4796ad09, 90b40ab29298db3a4879c1d3c4e685184386bce6.

Low priority for now. Upgrade to Linux Linux 84cba1840e68430325ac133a11be06bfb2f7acd8, 8cfbdda65588e75bfbd93e5ee847efcb4796ad09, 90b40ab29298db3a4879c1d3c4e685184386bce6 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

In the Linux kernel, the following vulnerability has been resolved: ice: copy last block omitted in ice_get_module_eeprom() ice_get_module_eeprom() is broken since commit e9c9692c8a81 ("ice: Reimplement module reads used by ethtool") In this refactor, ice_get_module_eeprom() reads the eeprom in blocks of size 8. But the condition that should protect the buffer overflow ignores the last block. The last block always contains zeros. Bug uncovered by ethtool upstream commit 9538f384b535 ("netlink: eeprom: Defer page requests to individual parsers") After this commit, ethtool reads a block with length = 1; to read the SFF-8024 identifier value. unpatched driver: $ ethtool -m enp65s0f0np0 offset 0x90 length 8 Offset Values ------ ------ 0x0090: 00 00 00 00 00 00 00 00 $ ethtool -m enp65s0f0np0 offset 0x90 length 12 Offset Values ------ ------ 0x0090: 00 00 01 a0 4d 65 6c 6c 00 00 00 00 $ $ ethtool -m enp65s0f0np0 Offset Values ------ ------ 0x0000: 11 06 06 00 00 00 00 00 00 00 00 00 00 00 00 00 0x0010: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 0x0020: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 0x0030: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 0x0040: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 0x0050: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 0x0060: 00 00 00 00 00 00 00 00 00 00 00 00 00 01 08 00 0x0070: 00 10 00 00 00 00 00 00 00 00 00 00 00 00 00 00 patched driver: $ ethtool -m enp65s0f0np0 offset 0x90 length 8 Offset Values ------ ------ 0x0090: 00 00 01 a0 4d 65 6c 6c $ ethtool -m enp65s0f0np0 offset 0x90 length 12 Offset Values ------ ------ 0x0090: 00 00 01 a0 4d 65 6c 6c 61 6e 6f 78 $ ethtool -m enp65s0f0np0 Identifier : 0x11 (QSFP28) Extended identifier : 0x00 Extended identifier description : 1.5W max.

No credits in the CNA record.

Variant candidates

Same product, same weakness class, within 18 months. If the patch missed the root cause, the sibling bug is here.

No nightly-computed relations.

Chain candidates

An authentication bypass and a privilege-requiring bug in the same product, published close together: combined they may become an unauthenticated path.
