CVE-2026-98540

The Linux kernel contains a vulnerability where fprobe_fgraph_entry() reserves shadow stack space but fails to clear the area if the entry handler does not return 0. This allows fprobe_return() to incorrectly parse unused tail data as headers from previous calls, potentially causing an exit handl...

In the Linux kernel, the following vulnerability has been resolved: fprobe: Terminate the fgraphdata list when the reservation is not filled fprobefgraphentry reserves shadow stack space for every fprobe with an exit handler, but only fills it for those whose entry handler returns 0...

CVE-2026-98539 fs/ntfs3: use d_instantiate_new() in ntfs_create_inode() and murder syzbot's "WARNING in do_new_mount" saga

In the Linux kernel, the following vulnerability has been resolved: fs/ntfs3: use dinstantiatenew in ntfscreateinode and murder syzbot's "WARNING in donewmount" saga ntfscreateinode creates a new inode via ntfsnewinode. It hashes it with insertinodelocked and so it's marked as INEW until...

CVE-2026-98539

The Linux kernel 's ntfs3 filesystem component contains a vulnerability where ntfs_create_inode() incorrectly interacts with d_instantiate() . Specifically, calling unlock_new_inode() after d_instantiate() causes lockdep_annotate_inode_mutex_key() to reset the i_rwsem count and owner while anothe...

CVE-2026-98538 writeback: bound cleanup_offline_cgwb() rescans by rotating scanned inodes

In the Linux kernel, the following vulnerability has been resolved: writeback: bound cleanupofflinecgwb rescans by rotating scanned inodes cleanupofflinecgwb prepares at most WBMAXINODESPERISW inodes per call and is called again until the dying wb is drained, but every call walks wb-battached and...

CVE-2026-98537

The Linux kernel contains a vulnerability in the workqueue subsystem where the check_flush_dependency() function performs a NULL pointer dereference . The issue occurs because current_wq_worker() confirms the process is a workqueue worker, but the worker->current_pwq pointer remains NULL if th...

CVE-2026-98538

The Linux kernel contains a performance issue in the writeback subsystem where the cleanup_offline_cgwb() function performs a quadratic drain of inodes. This occurs because the function repeatedly walks wb->b_attached and wb->b_dirty_time from the same end, causing it to rescanned a growing...

CVE-2026-98536

The Linux kernel contains a vulnerability where a worker draining a cgwb with millions of attached inodes fails to report a Tasks-RCU quiescent state during each drain pass. Due to how cond_resched() behaves on CONFIG_PREEMPTION kernels (specifically arm64 and x86 architectures in lazy mode), the...

CVE-2026-98535

The Linux kernel contains a clock reference leak within the fsl/fman component in the read_dts_node() function. The issue occurs because of_clk_get() increments a clock's reference count, but the function fails to call clk_put() after reading the rate. Since the clock is not stored, the reference...
