CVE-2026-19745

はじめに 皆さんこんにちは。5月に自宅のルーターでそこそこの脆弱性を発見しましたが、今日ようやく皆さんにお見せできます！ このリポジトリにある2つの脆弱性は、どちらも認証済みのサービス拒否（DoS）脆弱性です！ これらの脆弱性がどのように、なぜ発生するのか、正確な技術的詳細は分かっていません。Calix（このケースのベンダー）からは返答を一切もらえなかったので、まあ、楽しいですね！ また、これは私にとって初めてのCVEであり、2つ目のCVEでもあります。2つで1つ、お得ですね。 CVE-2026-19745 CVE-2026-19745...

Linux Distros Unpatched Vulnerability : CVE-2026-89469

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - power: supply: lp8727: fix use-after-free in lp8727releaseirq lp8727isrfunc, the threaded IRQ handler, is the only caller that arms pchg-work via...

CVE-2026-80989

A flaw was found in the Linux kernel's Thunderbolt networking subsystem. When a Thunderbolt connection fails to establish, the system may not correctly update its state, leading to repeated attempts to tear down an already inactive connection. This can result in a kernel warning and, under certai...

CVE-2026-89767

A flaw was found in the Linux kernel's overlay file system overlayfs. An unprivileged local user can trigger a specific error condition during the creation of a new directory. This error causes the system to incorrectly release a lock on the parent directory and a reference to the new directory...

CVE-2026-89712

A flaw was found in the Linux kernel's Network File System Daemon NFSD component. A race condition exists where, during the processing of unmounted source-server mounts, a thread may temporarily release a lock. During this window, another NFS Remote Procedure Call RPC thread can free memory that...

CVE-2026-89485

A flaw was found in the lockd component of the Linux kernel. This use-after-free vulnerability occurs in the nlmtraversefiles function when a file's memory is prematurely released while an iterator still holds a pointer to it. A remote attacker could potentially exploit this to cause system...

CVE-2026-89469

A flaw was found in the Linux kernel's lp8727 power supply driver. A race condition can occur during the release of an interrupt request IRQ, where a delayed work item might be re-armed after the associated memory has been freed. This can lead to a use-after-free vulnerability, potentially causin...

CVE-2026-89521

A flaw was found in the Linux kernel's core scheduling component. This issue occurs when the picktask function releases the run queue rq lock, allowing an interleaving selection to invalidate the scheduler's internal state. This inconsistency can lead to incorrect task selection and skewed resour...

CVE-2026-89690

A flaw was found in the nfsd component of the Linux kernel. This vulnerability, a use-after-free, occurs when a specific memory buffer is prematurely released while another process is still trying to access it. This timing issue can lead to memory corruption. This could result in a system crash...

DEBIAN-CVE-2026-89521

In the Linux kernel, the following vulnerability has been resolved: sched/core: Handle picktask releasing the rq lock Core scheduling's picknexttask breaks when a -picktask implementation can release the rq lock. The selection state derived on entry is only valid while the lock is held...
