CVE ID : CVE-2024-56710

Published : Dec. 29, 2024, 9:15 a.m. | 1 hour, 3 minutes ago

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).

Severity: 0.0 | NA
