CVE-2022-49114

HIGH 8.8 ALL-YEARS

Published 2025-02-26 · Last modified 2026-08-05 · Linux · NVD: Modified

In the Linux kernel, the following vulnerability has been resolved: scsi: libfc: Fix use after free in fc_exch_abts_resp() fc_exch_release(ep) will decrease the ep's reference count. When the reference count reaches zero, it is freed. But ep is still used in the following code, which will lead to a use after free. Return after the fc_exch_release() call to avoid use after free.
