CVE-2026-89438

This CVE affects the Linux kernel 's platform/x86: ISST (Intelligent Speed and Frequency Tuning Technology) driver. The root cause is a missing validation of the maximum CLOS ID and logical CPU ID for the core power feature. These values are used to calculate MMIO offsets , so an out-of-range val...

CVE-2026-80978

In the Linux kernel, the following vulnerability has been resolved: net: cap advertised IP tunnel headroom IP tunnel devices derive their advertised neededheadroom from lower output devices. A stack of user-created devices can make the derived value larger than the 16-bit skb header offsets can...

CVE-2026-80978

CVE-2026-80978 affects the Linux kernel networking subsystem, specifically the IP tunnel devices. When a local attacker stacks user-created IP tunnel devices, the derived needed_headroom can exceed the 16-bit skb header offset range, causing those offsets to wrap during skb head expansion. The fi...

CVE-2026-80959

CVE-2026-80959 affects the Linux kernel's dm-pcache (device-mapper persistent cache) component. The root cause is in cache_pos_decode() , which uses persisted key_tail and dirty_tail seg_off values to address data within a cache segment. A seg_off at or past the segment data_size , controllable b...
