kernel: gfs2: Fix unlikely race in gdlm_put_lock

A flaw was found in the Linux kernel’s Global File System 2 implementation affecting distributed lock manager DLM handling in the gdlmputlock function. During an unmount operation, if the DFLUNMOUNT flag is set but the lockspace has not yet been fully released, remote callbacks gdlmast or gdlmbas...

kernel: gfs2: Fix slab-use-after-free in qd_put

A flaw was found in the Linux kernel's GFS2 file system. During filesystem shutdown, quota data objects were freed without being properly removed from the Least Recently Used LRU list. This oversight could lead to a use-after-free vulnerability, where the system attempts to access memory that has...

kernel: gfs2: add some missing log locking

A flaw was found in the Linux kernel's Global File System 2 GFS2 component. The gfs2logd function, responsible for log flushing, calls several log flushing functions without holding the required lock. This omission allows concurrent transactions to access shared resources without proper exclusion...

SUSE CVE-2026-97520

In the Linux kernel, the following vulnerability has been resolved: gfs2: move quotainit qc iterator increment Move qc++ from the loop body into the for-loop increment expression in gfs2quotainit. This keeps iterator progression explicit and avoids mixing pointer advance with duplicate-slot...

CVE-2026-97521

A flaw was found in the Linux kernel's GFS2 Global File System 2 file system, which can lead to a Denial of Service DoS. In real-time kernel configurations, the quota initialization routine improperly invokes a sleeping function while holding an atomic lock. A local user capable of triggering GFS...

CVE-2026-97521

A bug in the Linux kernel 's gfs2 filesystem was identified where the gfs2_quota_init() function performed a duplicate quota ID check while holding the qd_lock and bucket bitlock . Specifically, the call to gfs2_qd_search_bucket() utilized lockref_get_not_dead(), which may sleep on PREEMPT_RT sys...

CVE-2026-97520

The Linux kernel contains a vulnerability within the gfs2 filesystem component in the gfs2_quota_init() function. The issue is caused by the qc++ iterator increment being located inside the loop body, which can lead to issues by mixing pointer advancement with duplicate-slot handling. To resolve ...
