Linux Kernel Use-After-Free Vulnerability in SCSI libfc Component

A use-after-free vulnerability has been identified in the Linux kernel's SCSI libfc component. The issue arises in the function fc_exch_abts_resp(), where the exchange's reference count is decreased before the exchange is released. Once the reference count reaches zero, the exchange is freed, but the code subsequently continues to use the now-freed exchange, leading to a use-after-free condition.

Impact

Exploitation of this vulnerability could lead to memory corruption issues, allowing for potential arbitrary code execution or other memory-related attacks.
