GHSA-C62G-6HM9-X69Q
Vulnerability from github – Published: 2024-12-29 09:30 – Updated: 2025-01-06 18:31In 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).
