Linux Distros Unpatched Vulnerability : CVE-2026-89567

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - jbd2: bound shrinker scans by examined checkpoint buffers The jbd2 shrinker currently accounts only checkpoint buffers that it successfully releases against...

CVE-2026-89759

A flaw was found in the Linux kernel's memory leak detector kmemleak. When kmemleakscan attempts to scan task stacks on systems with a large number of threads, it can hold a CPU for an extended period without allowing other processes to run. This can lead to a 'soft lockup,' where the system...

CVE-2026-89614

In the Linux kernel, the following vulnerability has been resolved: ntfs: bound the free-cluster bitmap scan to the volume vol-lcnemptybitsperpage is sized from vol-nrclusters at mount, but ntfsclusteralloc bounds its scan of that array by the size of $Bitmap. Those are independent on-disk...

DEBIAN-CVE-2026-89567

In the Linux kernel, the following vulnerability has been resolved: jbd2: bound shrinker scans by examined checkpoint buffers The jbd2 shrinker currently accounts only checkpoint buffers that it successfully releases against nrtoscan. Busy buffers therefore do not consume the scan budget. If a...

CVE-2026-89759

CVE-2026-89759 affects the Linux kernel's mm/kmemleak subsystem. The root cause is that kmemleak_scan() walks every task stack under a single rcu_read_lock() with no reschedule point; on hosts with a very large number of threads (amplified by KASAN/lockdep in debug builds), the loop can hog a CPU...

CVE-2026-89718

CVE-2026-89718 is an out-of-bounds access in the Linux kernel's zram module , specifically in the writeback_store() function. The root cause is a race condition: scan bounds are derived from zram->disksize before acquiring dev_lock. If the zram device is reset and reinitialized with a smaller ...
