kernel: xfrm: defensively unhash xfrm_state lists in __xfrm_state_delete

A flaw was found in the Linux kernel's xfrm IPSec framework subsystem. This vulnerability, a use-after-free, occurs when the system incorrectly manages memory related to security policies, specifically during the deletion of xfrmstate lists. An attacker with local access could exploit this flaw b...

CVE-2026-53364

A flaw was found in the Linux kernel's Bluetooth Host Controller Interface HCI connection handling. The hcilebigterminate function, which is responsible for terminating Bluetooth connections, allocates memory but fails to free it under specific conditions when certain flags are not set. This memo...

kernel: Linux kernel: netfilter: ebtables SNAT target writes to shared memory pages during ARP hardware address rewrite

A flaw was found in the Linux kernel's netfilter bridge ebtables SNAT Source Network Address Translation module. This vulnerability allows a local attacker on a system configured with specific bridge netfilter rules to improperly modify underlying memory pages during an ARP Address Resolution...

kernel: rtmutex: Use waiter::task instead of current in remove_waiter()

A flaw was found in the Linux kernel. When the kernel's real-time mutex rtmutex component performs a specific operation called 'proxy-lock rollback' during futex requeue, it incorrectly handles task pointers. This can lead to a 'Use-After-Free' UAF vulnerability, where the system attempts to use...

CVE-2026-53364

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: hciconn: Fix memory leak in hcilebigterminate hcilebigterminate allocates isolistdata via kzallocobj but returns 0 without freeing it when neither pasyncterm nor bigsyncterm flags are set after evaluating the PA and BI...

CVE-2026-53365

In the Linux kernel, the following vulnerability has been resolved: vsock/virtio: fix zerocopy completion for multi-skb sends When a large message is fragmented into multiple skbs, the zerocopy uarg is only allocated and attached to the last skb in the loop. Non-final skbs carry pinned user pages...

CVE-2026-53364

The CVE-2026-53364 entry concerns the Linux kernel Bluetooth HCI subsystem. A memory leak in hci_le_big_terminate() occurs when iso_list_data allocated via kzalloc_obj is not freed on an early return path after evaluating PA/BIG sync state (neither pa_sync_term nor big_sync_term flags set). This ...

CVE-2026-53365

In the Linux kernel, the following vulnerability has been resolved: vsock/virtio: fix zerocopy completion for multi-skb sends When a large message is fragmented into multiple skbs, the zerocopy uarg is only allocated and attached to the last skb in the loop. Non-final skbs carry pinned user pages...

kernel: md/bitmap: fix GPF in write_page caused by resize race

A flaw was found in the Linux kernel's md/bitmap component. This vulnerability involves a use-after-free race condition that occurs during array resize operations. When the bitmapdaemonwork and bitmapresize functions execute concurrently, they can access memory pages that have already been freed...

kernel: rtmutex: Use waiter::task instead of current in remove_waiter()

A flaw was found in the Linux kernel. When the kernel's real-time mutex rtmutex component performs a specific operation called 'proxy-lock rollback' during futex requeue, it incorrectly handles task pointers. This can lead to a 'Use-After-Free' UAF vulnerability, where the system attempts to use...

Ubuntu 18.04 LTS : Linux kernel (AWS) vulnerabilities (USN-8530-1)

"The remote Ubuntu 18.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-8530-1 advisory. It was discovered that the Linux kernel did not properly handle shared page fragments during socket buffer operations, collectively known as Dirty Frag....

Security Bulletin: IBM Storage Scale System: Vulnerability in Linux kernel crypto subsystem could allow local privilege escalation (CVE-2026-31431)

Summary IBM Storage Scale Systems is affected by a security vulnerability identified in the Linux kernel's cryptographic interface CVE-2026-31431 that could allow a local user with low privileges to escalate to root privileges. The vulnerability has a CVSS score of 7.8 High and requires local...

CVE-2026-53363

A flaw was found in the Linux kernel's iptfs component, part of the IPSec framework. The iptfsconsumefrags function does not correctly propagate a flag indicating shared fragments. This can cause the Encapsulating Security Payload ESP to make incorrect security decisions regarding in-place...

kernel: eventpoll: defer struct eventpoll free to RCU grace period

A flaw was found in the Linux kernel's eventpoll component. In certain situations, the epfree function in eventpoll.c can prematurely free the eventpoll data structure while it is still being used by another concurrent thread. This use-after-free UAF vulnerability could allow a local attacker to...

kernel: futex/requeue: Prevent NULL pointer dereference in remove_waiter() on self-deadlock

A flaw was found in the Linux kernel's futex Fast Userspace Mutex requeue mechanism. When a non-top waiter attempts to requeue a Priority Inheritance PI futex it already owns, a NULL pointer dereference can occur. This issue, specifically within the removewaiter function during a self-deadlock...
