CVE-2025-68774 hfsplus: fix missing hfs_bnode_get() in __hfs_bnode_create

In the Linux kernel, the following vulnerability has been resolved: hfsplus: fix missing hfsbnodeget in hfsbnodecreate When sync and link are called concurrently, both threads may enter hfsbnodefind without finding the node in the hash table and proceed to create it.

CVE-2025-68774

CVE-2025-68774 is a race in the Linux kernel’s hfsplus code where concurrent sync() and link() can create the same bnode, both threads end with refcnt=1 due to missing hfs_bnode_get(). When the second thread reuses the node from the hash, a BUG_ON triggers on refcnt. The fix is to call hfs_bnode_...

CVE-2023-53862

The CVE-2023-53862 entry documents a Linux kernel issue in hfs_bnode_create: a missing hfs_bnode_get() increases refcnt handling failures, leading to a kernel BUG (hfs_bnode_put) when refcnt is 0 during writeback. The root cause path is: allocation via hfs_bmap_alloc/hfs_bnode_find/__hfs_bnode_cr...
