CVE-2026-43319

A flaw was found in the Linux kernel's spidev driver. A local user, by performing concurrent write and ioctl operations on the same spidev file descriptor from separate threads, could trigger a lock inversion. This issue can lead to a deadlock, resulting in a Denial of Service DoS for the affecte...
