  3. CVE-2024-42289
In the Linux kernel, the following vulnerability has been resolved: scsi: qla2xxx: During vport delete send async logout explicitly During vport delete, it is observed that during unload we hit a crash because of stale entries in outstanding command array. For all these stale I/O entries, eh_abort was issued and aborted (fast_fail_io = 2009h) but I/Os could not complete while vport delete is in process of deleting.

Summary
  • (es) En el kernel de Linux, se resolvió la siguiente vulnerabilidad: scsi: qla2xxx: durante la eliminación de vport, envíe el cierre de sesión asíncrono explícitamente. Durante la eliminación de vport, se observa que durante la descarga sufrimos un bloqueo debido a entradas obsoletas en la matriz de comandos pendientes. Para todas estas entradas de E/S obsoletas, se emitió y canceló eh_abort (fast_fail_io = 2009h), pero las E/S no se pudieron completar mientras la eliminación de vport estaba en proceso de eliminación.
