{"id":"DEBIAN-CVE-2023-53142","details":"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.
