Description OSIDB Bzimport 2025-03-27 17:04:44 UTC 
In the Linux kernel, the following vulnerability has been resolved:

bnxt: Do not read past the end of test names

Test names were being concatenated based on a offset beyond the end of
the first name, which tripped the buffer overflow detection logic:

 detected buffer overflow in strnlen
 [...]
 Call Trace:
 bnxt_ethtool_init.cold+0x18/0x18

Refactor struct hwrm_selftest_qlist_output to use an actual array,
and adjust the concatenation to use snprintf() rather than a series of
strncat() calls.
