In the Linux kernel, the following vulnerability has been resolved:<\/p>\n
bnx2x: fix double free in bnx2x_init_firmware() error path<\/p>\n
bnx2x_init_firmware() frees bp->init_ops, bp->init_data and
\nbp->init_ops_offsets in its error path without setting them to NULL.
\nThe cleanup function bnx2x_release_firmware() frees the same three
\npointers unconditionally, so if init_firmware fails and
\nrelease_firmware is later called (e.g. from __bnx2x_remove or through
\nthe function state machine), all three are freed a second time.<\/p>\n
Set each pointer to NULL after kfree() in the error path so that the
\nsubsequent kfree(NULL) in bnx2x_release_firmware() is a safe no-op.<\/p>\n","protected":false},"excerpt":{"rendered":"
