Details

In the Linux kernel, the following vulnerability has been resolved:

staging: vmeuser: Fix possible UAF in tsi148dmalistadd

Smatch report warning as follows:

drivers/staging/vmeuser/vmetsi148.c:1757 tsi148dmalist_add() warn: '&entry->list' not removed from list

In tsi148dmalistadd(), the error path "goto errdma" will not remove entry->list from list->entries, but entry will be freed, then list traversal may cause UAF.

Fix by removeing it from list->entries before free().
