CVE-2026-80693

In the Linux kernel idpf driver , idpf_get_reg_intr_vecs() fills a caller-allocated reg_vals[] array using a loop bounded only by per-chunk num_vectors from a VIRTCHNL2_OP_ALLOC_VECTORS reply. The array is sized from caps.num_allocated_vectors, but the sum of per-chunk num_vectors is never reconc...

In the Linux kernel, the following vulnerability has been resolved: idpf: bound interrupt-vector register fill to the allocated array idpfgetregintrvecs fills the caller-allocated regvals array from the VIRTCHNL2OPALLOCVECTORS reply in adapter-reqvecchunks, bounding its inner loop only by the...

CVE-2026-68291

A flaw was found in the Linux kernel's idpf driver. During initialization, if memory allocation for virtual port vport related buffers fails, the driver may attempt to access a null pointer when the module is removed or the system is reset. This can lead to a kernel null pointer dereference,...

CVE-2026-68291

CVE-2026-68291 covers a Linux kernel fix for the idpf driver: max_vports is now set only after successful allocation of vports, netdevs, and vport_config buffers, preventing crashes on reset or rmmod after a failed init. The description documents a kernel NULL pointer dereference in idpf_remove d...

Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: idpf: fixed a memory leak in idpfvportrel Freeed vport-rxptypelkup from idpfvportrel to prevent memory leakage during a reset. Reported by kmemleak: Unreferenced object 0xff450acac838a000 size 4096: comm "kworker/u258:5", pid 773...

CVE-2026-64162

A flaw was found in the Linux kernel's Intel Ethernet controller driver idpf. This vulnerability occurs because a critical synchronization mechanism, known as a spinlock, is accessed before it has been properly initialized. An attacker could potentially exploit this timing issue to cause the syst...

CVE-2026-64162

In the Linux kernel, the following vulnerability has been resolved: idpf: fix readdevclklock spinlock init in idpfptpinit In idpfptpinit, readdevclklock is initialized after ptpscheduleworker had already been called and after idpfptpsettime64 could reach the lock. The PTP aux worker fires...

CVE-2026-53286

A flaw was found in the Linux kernel. Specifically, a double free and use-after-free vulnerability exists in the idpf driver's auxiliary device error paths. This flaw occurs when auxiliarydeviceadd fails, leading to improper memory handling where memory is freed twice or accessed after being free...

EUVD-2026-39891

In the Linux kernel, the following vulnerability has been resolved: idpf: fix double free and use-after-free in aux device error paths When auxiliarydeviceadd fails in idpfplugvportauxdev or idpfplugcoreauxdev, the errauxdevadd label calls auxiliarydeviceuninit and falls through to errauxdevinit...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: idpf: fixed the issue where the aux device is unplugged when RDMA is not supported by the vport. If the vport flags do not contain VIRTCHNL2VPORTENABLERDMA, the driver does not allocate vdevinfo for this vport. This results in a...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: idpf: checked for errors when calling registernetdev in init. The current init logic ignores the error code from registernetdev. This could lead to a WARNON message when attempting to unregister the device, if such an attempt...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: idpf: Detaching and closing netdevs while handling a reset Protect the reset path from callbacks by setting the netdevs to detached state and closing any netdevs in UP state until the reset handling is completed. During a reset,...

CVE-2026-31647

A flaw was found in the Linux kernel's idpf driver. This vulnerability arises from improper nesting of spinlocks during asynchronous Virtual Channel VC handling. An attacker could potentially trigger an invalid wait context, leading to a system crash or denial of service. Mitigation To reduce...

CVE-2026-31647

In the Linux kernel, the following vulnerability has been resolved: idpf: fix PREEMPTRT raw/bh spinlock nesting for async VC handling Switch from using the completion's raw spinlock to a local lock in the idpfvcxn struct.
