This vulnerability has been modified since it was last analyzed by the NVD. It is awaiting reanalysis which may result in further changes to the information provided.
Current Description
In the Linux kernel, the following vulnerability has been resolved:
smb: client: fix possible double free in smb2_set_ea()
Clang static checker(scan-build) warning:
fs/smb/client/smb2ops.c:1304:2: Attempt to free released memory.
1304 | kfree(ea);
| ^~~~~~~~~
There is a double free in such case:
'ea is initialized to NULL' -> 'first successful memory allocation for
ea' -> 'something failed, goto sea_exit' -> 'first memory release for ea'
-> 'goto replay_again' -> 'second goto sea_exit before allocate memory
for ea' -> 'second memory release for ea resulted in double free'.
Re-initialie 'ea' to NULL near to the replay_again label, it can fix this
double free problem.
