CVE-2026-89498

CVE-2026-89498 affects the orangefs (PVFS2) module in the Linux kernel. On a readdir downcall, orangefs_devreq_write_iter() frees op->downcall.trailer_buf via vfree() when copy_from_iter_full() fails but does not clear the pointer before jumping to the error path. The waiter in do_readdir() is...

CVE-2026-89497

A heap buffer overflow exists in the Linux kernel's OrangeFS (orangefs) client, specifically in the function orangefs_prepare_cdm_array(). The function sizes each client debug keyword buffer using strcspn(cds_head, " "), which does not skip leading spaces, but then parses the keyword with the %s ...

CVE-2026-89495

CVE-2026-89495 affects the OCFS2/DLM (o2dlm) subsystem in the Linux kernel . The migration and recovery message handlers trust peer-supplied u8 length fields (namelen, lockname_len, num_locks) without bounding them before passing them to memcpy, resulting in a heap out-of-bounds write of up to ~2...

CVE-2026-89496

CVE-2026-89496 is a memory leak in the Linux kernel OCFS2 filesystem, discovered via local fuzzing of version 6.12.94 . The leak occurs when copy_file_range() is called within the same OCFS2 filesystem, triggering a copy-on-write path that fails to release deallocation caches (ocfs2_cache_block_d...
