CVE-2025-71238

Estado: AnalizadaAlta (7.8)—

In the Linux kernel, the following vulnerability has been resolved:

scsi: qla2xxx: Fix bsg_done() causing double free

Kernel panic observed on system,

Most routines in qla_bsg.c call bsg_done() only for success cases. However a few invoke it for failure case as well leading to a double free. Validate before calling bsg_done().
