- Summary
- net: ftgmac100: fix ring allocation unwind on open failure
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
net: ftgmac100: fix ring allocation unwind on open failure
ftgmac100allocrings() allocates rxskbs, txskbs, rxdes, txdes, and rx_scratch in stages. On intermediate failures it returned -ENOMEM directly, leaking resources allocated earlier in the function.
Rework the failure path to use staged local unwind labels and free allocated resources in reverse order before returning -ENOMEM. This matches common netdev allocation cleanup style.
