CVE-2026-43448 nvme-pci: Fix race bug in nvme_poll_irqdisable()

In the Linux kernel, the following vulnerability has been resolved: nvme-pci: Fix race bug in nvmepollirqdisable In the following scenario, pdev can be disabled between 1 and 3 by 2. This sets pdev-msixenabled = 0. Then, pciirqvector will return MSI-X IRQ15 for 1 whereas return INTx IRQcqvector...

CVE-2026-43293

CVE-2026-43293: Linux kernel wave5 media driver in polling mode fixes a race between hrtimer cancellation and kthread worker destruction. The wave5_vpu_timer_callback() queues work via kthread_queue_work(), and destroying the worker before cancelling the hrtimer could let the timer fire during de...

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - nvme-pci: Fix race bug in nvmepollirqdisable In the following scenario, pdev can be disabled between 1 and 3 by 2. This sets pdev-msixenabled = 0. Then,...

CVE-2026-43252

A flaw was found in the MultiPath TCP MPTCP subsystem of the Linux kernel. A local attacker could exploit a logic error in how MPTCP manages network connection endpoints. By performing a specific sequence of operations, an attacker could trigger a kernel warning, potentially leading to system...

CVE-2026-43244

A flaw was found in the Linux kernel's Kernel Connection Multiplexer KCM module. A local user could trigger an issue where, during partial sendmsg operations, an empty network buffer skb is incorrectly left in the fraglist. A subsequent zero-length write operation can then cause a kernel warning,...

CVE-2026-43180

A flaw was found in the Linux kernel's kaweth USB network driver. The kawethsetrxmode function incorrectly manipulates the transmit TX queue, allowing it to be re-enabled while a USB Request Block URB is still active. This can result in the same URB being submitted twice, leading to a kernel...

CVE-2026-43252

In the Linux kernel, the following vulnerability has been resolved: mptcp: pm: in-kernel: always set ID as avail when rm endp Syzkaller managed to find a combination of actions that was generating this warning: WARNING: net/mptcp/pmkernel.c:1074 at marksubflowendpavailable net/mptcp/pmkernel.c:10...

CVE-2026-31689

A flaw was found in the EDAC/mc module of the Linux kernel. An error in the ordering of operations within the edacmcalloc function can lead to a situation where a device's release function is called before the device is fully initialized. This improper initialization can result in a kernel warnin...

Linux Distros Unpatched Vulnerability : CVE-2026-31545

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - NFC: nxp-nci: allow GPIOs to sleep Allow the firmware and enable GPIOs to sleep. This fixes a WARNON' and allows the driver to operate GPIOs which are connected...

CVE-2026-31555

A flaw was found in the Linux kernel. A local user could exploit a race condition within the futexlockpi retry path. This vulnerability occurs because a stale pointer to an exiting process is not cleared, leading to a kernel warning. Successful exploitation of this flaw could result in a system...

CVE-2026-31551

A flaw was found in the mac80211 Wi-Fi subsystem of the Linux kernel. A local user could exploit a race condition in the aqlenablewrite function, which does not properly handle concurrent write operations to the debug file system. This could lead to a staticbranchdec underflow, resulting in a...
