Until a fix is available, users should monitor kernel updates and consider avoiding affected driver usage in critical environments if possible.
Description
CVE-2025-37897 is a medium severity vulnerability in the Linux kernel's plfxlc wireless driver. It involves an erroneous assertion in the plfxlc_mac_release() function that incorrectly expects a lock to be held when it should not be. This leads to a kernel warning and potential instability during device probe failure or disconnection. The issue does not affect confidentiality or integrity but impacts availability by causing kernel warnings and possible crashes.
