CVE-2026-99087 dm-integrity: fix NULL pointer dereference when the 'R' flag is used

In the Linux kernel, the following vulnerability has been resolved: dm-integrity: fix NULL pointer dereference when the 'R' flag is used If the dm-integrity device has the SBFLAGDIRTYBITMAP flag set and the user activates the device in the 'R' mode, a crash in dmintegrityresume happens because th...

CVE-2026-99087

The Linux kernel contains a vulnerability in the dm-integrity component where a NULL pointer dereference occurs during dm_integrity_resume. This issue is triggered when a device has the SB_FLAG_DIRTY_BITMAP flag set and is activated in 'R' mode , causing the function to incorrectly attempt to rea...

CVE-2026-99074

The Linux kernel contains a vulnerability where a null-pointer dereference can occur during the PMTU (Path MTU) walk process. The root cause is a race condition: while RCU protects the lifetime of nexthop groups, it does not ensure that fib_info_num_path() and fib_info_nhc() observe the same grou...

In the Linux kernel, the following vulnerability has been resolved: ipv4: stop PMTU walk when nexthop group shrinks Commit 7d3f3b4367f3 "net: ipv4: Cache pmtu for all packet paths if multipath enabled" made iprtupdatepmtu update every path. For nexthop objects, fibinfonumpath and fibinfonhc...

CVE-2026-99073

The Linux kernel contains a vulnerability where an IPv4 Forwarding Information Base (FIB) dump could lead to a null pointer dereference. The issue occurs because fib_dump_info_fnhe() uses a loop bound that may become invalid if an RTM_NEWNEXTHOP operation replaces a nexthop group with fewer paths...

CVE-2026-99072

A vulnerability exists in the Linux kernel networking stack related to ipv4 route notifications. The issue occurs because fib_nlmsg_size() performs an RCU-only call where fib_info_nhc() independently reloads nh->nh_grp. If RTM_NEWNEXTHOP replaces a group with fewer paths between these two oper...

In the Linux kernel, the following vulnerability has been resolved: ipv4: stop route notification sizing when nexthop group shrinks Commit 680aea08e78c "net: ipv4: Emit notification when fib hardware flags are changed" added an RCU-only fibnlmsgsize call for asynchronous hardware flag...

CVE-2026-99065

The Linux kernel is affected by a CPU hotplug race condition within the cgroup/cpuset subsystem, specifically in the guarantee_active_cpus() function. The issue arises during CPU offline operations because the cpu_active_mask is updated in sched_cpu_deactivate() before cpuset_handle_hotplug() can...

In the Linux kernel, the following vulnerability has been resolved: cgroup/cpuset: Handle cpu hotplug race in guaranteeactivecpus With commit 2125c0034c5d "cgroup/cpuset: Make cpuset hotplug processing synchronous", the cpuset hotplug operation becomes synchronous. That commit also removes the co...

CVE-2026-99060

A vulnerability exists in the Linux kernel 's mt7603 driver. The driver uses a driver-private global station WCID for frames without a station or vif, such as those injected via a monitor interface . Because this WCID is published without being passed to mt76_wcid_init(), the first injected frame...

In the Linux kernel, the following vulnerability has been resolved: wifi: mt76: mt7603: initialize global station WCID mt7603 uses a driver-private global station WCID for frames that have neither a station nor a vif, including frames injected through a monitor interface. Unlike the core global...

CVE-2026-99058

The Linux kernel contains a vulnerability in the workqueue subsystem where a NULL pointer dereference can occur during a chained work check. The current_wq_worker() function identifies a kworker , but it does not guarantee the worker is actively executing a work item; the worker->current_pwq m...

In the Linux kernel, the following vulnerability has been resolved: workqueue: Fix NULL currentpwq deref in chained work check currentwqworker only tells us that %current is a kworker. It does not guarantee that the worker is currently executing a work item, as worker-currentpwq is populated only...

CVE-2026-99055

The Linux kernel contains a vulnerability where the can_map_frag() function dereferences a null pointer when processing net_iov fragments during zerocopy receive mapping . Specifically, skb_frag_page() returns NULL for a net_iov, but can_map_frag() fails to handle this, leading to a null-ptr-dere...

In the Linux kernel, the following vulnerability has been resolved: tcp: reject netiov in zerocopy receive mapping hints After copying a readable prefix, receivefallbacktocopy asks tcpzerocopysethintforskb where page mapping can resume. If the next skb is unreadable, findnextmappablefrag passes i...

CVE-2026-99041

The Linux kernel contains a vulnerability in the ip6_gre module where a tc tunnel_key action can attach a METADATA_IP_TUNNEL dst to an skb. When mirred redirects this to a native ip6erspan device , the legacy PMTU update in ip6erspan_tunnel_xmit() incorrectly treats the metadata destination as a ...

In the Linux kernel, the following vulnerability has been resolved: ip6gre: remove obsolete ERSPAN PMTU update A tc tunnelkey action can attach a METADATAIPTUNNEL dst to an skb, and mirred can redirect it to a native ip6erspan device. The legacy PMTU update in ip6erspantunnelxmit treats that...

CVE-2026-99024

The Linux kernel contains a vulnerability where optee_probe() calls tee_device_register() for both client and supplicant devices before the struct optee is fully initialized. Because tee_device_register() creates device nodes and links the device into the tee class, the device becomes accessible ...
