Title:
mlx-bootctl: Fix potential buffer overflow
Status in linux-bluefield package in Ubuntu:
New
Bug description:
SRU Justification:
[Impact]
The sysfs store/show functions use sprintf without specifying a size which
could lead to potential buffer overflow.
[Fix]
Replace sprintf with snprintf to avoid buffer overflow. Also, remove the
redundant strlen usage since count is already available in the _store functions.
[Test Plan]
Read/write access to the EEPROM MFG fields can be tested via the sysfs
entries that are exposed by the driver. Please note that the MFG partition is
locked in order to protect the data and this could block all writes to it. In
order to enable writes to the EEPROM, the MFG Info needs to be reset via the
UEFI Device Manager.
[Regression Potential]
Can be considered minimum.
