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-2026-98538

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...

CVE-2026-98534

A use-after-free vulnerability exists in the Linux kernel within the ipe component. The issue occurs because new_policy() audits a policy after ipe_new_policyfs_node() publishes it and releases the new directory's inode lock . This allows a concurrent delete operation to free the policy while ipe...
