UBUNTU-CVE-2026-97533

In the Linux kernel, the following vulnerability has been resolved: x86/mm/pat: Acquire initmm read lock on attribute changes to avoid UAF A previous commit protected against races between ptdump and CPA collapse, however one still exists between attribute changes and collapse as reported by Deni...

CVE-2026-98136

In the Linux kernel, the following vulnerability has been resolved: ntfs: bound $AttrDef table walk to the loaded table size ntfsattrfindinattrdef walks the in-memory $AttrDef table, but the loop condition bounds only the start of each entry, not the whole entry: for ad = vol-attrdef; u8 ad - u8...

CVE-2026-98136

The Linux kernel contains a vulnerability in the ntfs file system where the ntfs_attr_find_in_attrdef() function fails to properly bound the walk of the in-memory $AttrDef table. The loop condition only checks the start of each entry rather than the entire 160-byte struct attr_def, allowing a rea...

CVE-2026-97974

The Linux kernel contains a null-pointer dereference vulnerability within the ipv6 networking stack, specifically in the __ip6_del_rt_siblings() function. The issue occurs because rt->fib6_node can be set to NULL by a concurrent thread (e.g., when replacing an ECMP route via RTM_NEWROUTE with ...

CVE-2026-97939

The Linux kernel is affected by a vulnerability where a netadmin in a user+net namespace could create numerous IPv4 and IPv6 multicast routing tables using MRT_TABLE and MRT6_TABLE. Because these mr_table objects were not charged to memcg , the host's unreclaimable slab would grow proportionally ...

CVE-2026-97939 ipmr: account multicast table and route memory

In the Linux kernel, the following vulnerability has been resolved: ipmr: account multicast table and route memory A netadmin in a user+net namespace can create many IPv4 and IPv6 multicast routing tables with MRTTABLE and MRT6TABLE. Each unseen id allocates an mrtable via the shared mrtablealloc...

CVE-2026-97611

The Linux kernel contains a use-after-free vulnerability in the Open vSwitch component involving the flow table mask array. The issue exists in tbl_mask_array_realloc(), where call_rcu() is invoked to retire the old mask_array before it is no longer reachable. Because the pointer swap with rcu_as...

CVE-2026-97598

The Linux kernel contains a vulnerability in the ipv4: fib component where the fib_empty_table() function probes every table ID starting from 1 until a free one is found. In a dense set of IDs, this causes each probe to walk a growing hash chain while the RTNL is held. To mitigate this, the autom...
