Mô tả CVE
In the Linux kernel, the following vulnerability has been resolved:
bnx2x: fix double free in bnx2x_init_firmware() error path
bnx2x_init_firmware() frees bp->init_ops, bp->init_data and
bp->init_ops_offsets in its error path without setting them to NULL.
The cleanup function bnx2x_release_firmware() frees the same three
pointers unconditionally, so if init_firmware fails and
release_firmware is later called (e.g. from __bnx2x_remove or through
the function state machine), all three are freed a second time.
Set each pointer to NULL after kfree() in the error path so that the
subsequent kfree(NULL) in bnx2x_release_firmware() is a safe no-op.
