CVE-2026-53366
The CVE-2026-53366 fix applies to the Linux kernel IPv4 stack, specifically the paged-allocation path in __ip_append_data(). The issue arises when fraggap from the previous skb is copied into the new skb’s linear area; alloclen and pagedlen were computed as alloclen = fragheaderlen + transhdrlen ...
The vulnerabilities in the net/bluetooth/eir.c and net/bluetooth/mgmt.c modules of Linux kernel allow a hacker to cause a service failure.
The vulnerability in the net/bluetooth/eir.c and net/bluetooth/mgmt.c modules of Linux kernel systems relates to the execution of operations beyond the buffer boundaries in memory. Exploiting this vulnerability can allow an attacker to cause a system failure...
CVE-2026-14961
Pegatron Tdelo64.sys exposes a privileged device interface, \.\TdeIo, that fails to properly restrict access to sensitive IOCTL functionality. The driver's IOCTL dispatcher does not validate caller privileges or verify user-supplied kernel memory addresses before performing memory operations. By...

CVE-2026-14961
CVE-2026-14961 affects Pegatron tdeio64.sys exposing the .�5cTdeIo device. The IOCTL dispatch lacks privilege validation and does not validate user-supplied kernel addresses, allowing arbitrary kernel memory read/write and privilege escalation to NT AUTHORITY\SYSTEM. The linked explainer also not...
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...
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...
Important: Red Hat Security Advisory: kernel security update
An update for kernel is now available for Red Hat Enterprise Linux 9.2 Update Services for SAP Solutions. Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System CVSS base score, which gives a detailed severity rating, is...
kernel: netfilter: nf_conntrack_helper: pass helper to expect cleanup
A flaw was found in the Linux kernel's netfilter subsystem, specifically within the nfconntrackhelper. When a connection tracking helper is unregistered, its associated expectations are not properly cleaned up. This oversight can lead to a use-after-free vulnerability, where the system attempts t...
kernel: KVM: x86: Fix shadow paging use-after-free due to unexpected role
A flaw was found in the Linux kernel's Kernel-based Virtual Machine KVM x86 shadow paging mechanism. This vulnerability occurs when a host page directory entry PDE mapping is changed from within the guest, leading to an unexpected role mismatch in shadow paging. This mismatch can cause a...

kernel: nvmet-tcp: fix race between ICReq handling and queue teardown
A flaw was found in the Linux kernel's NVMe over TCP nvmet-tcp implementation. A race condition exists between the handling of an Initialization Connection Request ICReq and the teardown of a queue. A remote attacker, by sending an ICReq and immediately closing the connection, could trigger a...
kernel: net: sched: act_csum: validate nested VLAN headers
A flaw was found in the Linux kernel's network scheduler component. A remote attacker could send specially crafted network packets containing nested Virtual Local Area Network VLAN headers. This could cause the kernel to read beyond allocated memory, leading to a system crash and a denial of...
kernel: smb: client: fix OOB reads parsing symlink error response
A flaw was found in the Linux kernel's Server Message Block SMB client. A remote, untrusted server could send a specially crafted symlink error response, leading to an out-of-bounds read vulnerability. This could result in the disclosure of sensitive information from the kernel's memory to a loca...

kernel: RDMA/vmw_pvrdma: Fix double free on pvrdma_alloc_ucontext() error path
A flaw was found in the Linux kernel, specifically within the RDMA Remote Direct Memory Access vmwpvrdma module. This vulnerability is a double free, which means the system attempts to release the same memory resource twice. This can occur in an error handling path within the pvrdmaallocucontext...
