CVSS 3.1
7.8 highCVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:HCVE-2024-49852
High (7.8) in linux linux kernel. EPSS 0.2% chance of exploitation in the next 30 days.
In the Linux kernel, the following vulnerability has been resolved:
scsi: elx: libefc: Fix potential use after free in efc_nport_vport_del()
The kref_put() function will call nport->release if the refcount drops to
zero. The nport->release release function is _efc_nport_free() which frees
"nport". But then we dereference "nport" on the next line which is a use
after free. Re-order these lines to avoid the use after free.
