Title
crypto: nx - fix bounce buffer leaks in nx842_crypto_{alloc,free}_ctx
Summary
In the Linux kernel, the following vulnerability has been resolved:
crypto: nx - fix bounce buffer leaks in nx842_crypto_{alloc,free}_ctx
The bounce buffers are allocated with __get_free_pages() using
BOUNCE_BUFFER_ORDER (order 2 = 4 pages), but both the allocation error
path and nx842_crypto_free_ctx() release the buffers with free_page().
Use free_pages() with the matching order instead.
Severity
