What is CVE-2023-53010?
CVE-2023-53010 is a medium-severity memory corruption vulnerability in Linux kernel, published on 27 Mar 2025. It can only be exploited from the same machine or local network, with no action from the victim.
Official description
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.
Which versions are affected by CVE-2023-53010?
It affects 1 product.
