  "details" : [ "In the Linux kernel, the following vulnerability has been resolved:\nscsi: libfc: Fix use after free in fc_exch_abts_resp()\nfc_exch_release(ep) will decrease the ep's reference count. When the\nreference count reaches zero, it is freed. But ep is still used in the\nfollowing code, which will lead to a use after free.\nReturn after the fc_exch_release() call to avoid use after free.", "A vulnerability was found in the Linux kernel's SCSI libfc library in the `fc_exch_abts_resp()` function, which can lead to a use-after-free scenario. This issue can occur because the function calls `fc_exch_release()`, which decrements a reference count stored in the `ep` object and then frees the object once the count is zero. However, the `ep` object is referenced again and can result in the now-freed `ep` pointer being accessed, resulting in system instability, memory corruption, and potential arbitrary code execution." ],
