CVE-2024-56710 Information

Description

In the Linux kernel the following vulnerability has been resolved:

ceph: fix memory leak in ceph_direct_read_write()

The bvecs array which is allocated in iter_get_bvecs_alloc() is leaked and pages remain pinned if ceph_alloc_sparse_ext_map() fails.

There is no need to delay the allocation of sparse_ext map until after the bvecs array is set up so fix this by moving sparse_ext allocation a bit earlier. Also make a similar adjustment in __ceph_sync_read() for consistency (a leak of the same kind in __ceph_sync_read() has been addressed differently).
