Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: ice: fix vsi-txqmap sizing The approach of having XDP queue per CPU regardless of user's setting exposed a hidden bug that could occur in case when Rx queue count differ from Tx queue count. Currently vsi-txqmap's size is equal t...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, and Linux 5.15

In the Linux kernel, the following vulnerabilities have been resolved: i40e: added validation for the ringlen parameter. The ringlen parameter provided by the virtual function VF is assigned directly to the hardware memory context HMC without any validation. To address this issue, a upper boundar...

Cryptanalysis of a Class of Ideal Secret Sharing Schemes Based on the CRT for Polynomial Rings

Based on the CRT for polynomial rings, Yang, Zhu, Fu and Xia ISIT 2026 proposed a compartmented secret sharing scheme for the compartmented access structure with lower bounds, claiming it can be ideal. We exhibit three families of unauthorized subsets that reconstruct the secret. The scheme is...

Beyond Account-Level Risk: An Evidence-to-Action Pipeline for Detecting Fraud Rings

Linkage analysis connects accounts, devices and infrastructure to detect coordinated fraud rings that traditional account-level risk controls may fail to identify...

CVE-2026-97569 bnxt_en: Prevent queue stop with deferred completions

In the Linux kernel, the following vulnerability has been resolved: bnxten: Prevent queue stop with deferred completions When the driver receives a burst of packets, it can mark a BD with the NOCMPL bit to defer completions. The expectation is that the last packet in the ring will have this bit...

PT-2026-98512

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description An issue exists in the bnxt en driver where the bnxt init nic function fails to propagate error return values from bnxt init rx rings. When bnxt alloc one rx ring fails, the return value...

EUVD-2026-82262

In the Linux kernel, the following vulnerability has been resolved: RDMA/irdma: Add refcounting to user ring MRs Prevent userspace from deregistering the MRs that back QP/CQ/SRQ rings by bumping the MR's refcount upon association...

AZL-101303 CVE-2026-89827 affecting package kernel 6.6.157.1-1

In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: avoid force-completing uninitialized UVD rings uvdv70swinit does not initialize the UVD decode ring for an SR-IOV VF. However, amdgpuuvdresume unconditionally force-completes the decode ring when restoring its fence...

Astra Linux – Vulnerability in Linux 5.10, Linux

In the Linux kernel, the following vulnerability has been resolved: Ethernet: Aeroflex – Fix for a potential skb leak in grethinitrings The grethinitrings function does not free the newly allocated skb when dmamappingerror returns an error. Therefore, adding devkfreeskb is necessary to fix this...

Astra Linux – Vulnerability in Linux 5.10, Linux

In the Linux kernel, the following vulnerabilities have been resolved: xen-netfront: Fixed NULL pointers after live migration. NAPIs are set up for each network interface to poll data for the kernel. The interface with the source host is destroyed during live migration, and a new interface with t...

UBUNTU-CVE-2026-80610

In the Linux kernel, the following vulnerability has been resolved: net: enetc: fix potential divide-by-zero when numvsi is zero For i.MX94 series, all the standalone ENETCs do not support SR-IOV, so pf-caps.numvsi is zero. This leads to a divide-by-zero in enetc4defaultringsallocation when...

EUVD-2026-67448

In the Linux kernel, the following vulnerability has been resolved: iouring: preserve task restrictions across exec Per-task restrictions apply to all rings created by a task. Once installed, they should not be dropped across exec. For a task that has used iouring, the exec cancellation path call...

CVE-2026-80713

CVE-2026-80713 is a Linux kernel vulnerability in the io_uring subsystem. The root cause is that per-task io_uring restrictions are incorrectly released during the exec cancellation path : the function __io_uring_free() frees both the task context and the per-task restriction, so any ring created...

CVE-2026-80610 net: enetc: fix potential divide-by-zero when num_vsi is zero

In the Linux kernel, the following vulnerability has been resolved: net: enetc: fix potential divide-by-zero when numvsi is zero For i.MX94 series, all the standalone ENETCs do not support SR-IOV, so pf-caps.numvsi is zero. This leads to a divide-by-zero in enetc4defaultringsallocation when...

CVE-2026-80576

A flaw was found in the Linux kernel's drm/amdgpu component. A local attacker could exploit this vulnerability by providing oversized input buffer IB bytes to the amdgpucsp2ib function on Graphics GFX rings. This lack of size validation allows the oversized values to corrupt adjacent control bits...

PT-2026-82192

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description In the drm/amdgpu component, the amdgpu cs p2 ib function fails to limit user-supplied ib bytes when passing them to ib-length dw. Because ring emit ib encodes this length into packet...
