  3. CVE-2026-23256
In the Linux kernel, the following vulnerability has been resolved: net: liquidio: Fix off-by-one error in VF setup_nic_devices() cleanup In setup_nic_devices(), the initialization loop jumps to the label setup_nic_dev_free on failure. The current cleanup loop while(i--) skip the failing index i, causing a memory leak. Fix this by changing the loop to iterate from the current index i down to 0. Compile tested only. Issue found using code review.

Summary
  • (es) En el kernel de Linux, la siguiente vulnerabilidad ha sido resuelta: net: liquidio: Corrección de error de uno en la limpieza de VF setup_nic_devices() En setup_nic_devices(), el bucle de inicialización salta a la etiqueta setup_nic_dev_free en caso de fallo. El bucle de limpieza actual while(i--) omite el índice i que falla, causando una fuga de memoria. Esto se corrige cambiando el bucle para que itere desde el índice actual i hasta 0. Solo probado en compilación. Problema encontrado mediante revisión de código.
