CVE-2026-74285

A flaw was found in the Linux kernel's network subsystem. An issue in the netifrxqcleanupunlease function, responsible for tearing down network queue memory providers, allows a device to perform Direct Memory Access DMA to an incorrect memory address. This occurs because the DMA mappings are...

CVE-2026-74280

A flaw was found in the Linux kernel's marvell/octeontx cryptographic driver. This issue occurs during Direct Memory Access DMA cleanup, where an incorrect loop index is used. This can lead to memory leaks by failing to unmap successfully mapped entries and repeatedly attempting to unmap already...

CVE-2026-74279

A flaw was found in the Linux kernel's cavium/cpt cryptographic driver. An incorrect loop index in the sgcleanup error path during Direct Memory Access DMA buffer unmapping could lead to resource exhaustion. This issue results in successfully mapped entries being leaked and failed entries being...

CVE-2026-74278

A flaw was found in the Linux kernel's Advanced Linux Sound Architecture ALSA sequencer. A local attacker could exploit a vulnerability in the bounceerrorevent function, which improperly handles bounce error events for user clients. This flaw allows for the disclosure of kernel heap memory...

CVE-2026-74277

A flaw was found in the Linux kernel's iommu/dma-iommu component. When handling PCI Peer-to-Peer Direct Memory Access P2PDMA cases, an incorrect assignment of the scatterlist length can cause all segments in a multi-segment scatterlist to inherit the length of the first segment. This leads to...

CVE-2026-74275

A flaw was found in the Linux kernel. A vulnerability exists in the cxlcancelautoattach function where an invalid negative index can be used to access an array. This out-of-bounds memory access could allow a local attacker to cause system instability or a denial of service DoS...

CVE-2026-74273

A flaw was found in the Linux kernel's cxl/region component. A local user could exploit a race condition during the creation and deletion of regions. This could lead to the kernel becoming confused about the state of a region, potentially causing system instability or a denial of service DoS...

CVE-2026-74272

A flaw was found in the Linux kernel's cxl/region module. Multiple race conditions exist during the deletion of CXL Compute Express Link regions. A local attacker could exploit these race conditions by repeatedly attempting to delete a region via the sysfs interface or by racing with kernel...

CVE-2026-74283

A flaw was found in the Linux kernel's Transparent Inter-Process Communication TIPC version 2 component. This vulnerability allows a local unprivileged attacker to bypass administrative permission checks when performing network link operations. Consequently, the attacker can modify critical TIPC...

CVE-2026-74267

A flaw was found in the Linux kernel's schcodel Controlled Delay component, which manages network packet queues. When schcodel processes packets, it can incorrectly reduce the queue's size before it is properly updated. This error can lead to the premature deactivation of a parent queue, such as...

CVE-2026-74266

A flaw was found in the Linux kernel's schdualpi2 network scheduler. When the scheduler processes network packets, it can incorrectly manage its internal queue length. This mismanagement can lead to a system crash, making the system unavailable Denial of Service...

CVE-2026-72389

A flaw was found in the Linux kernel's bridge Spanning Tree Protocol STP module. A missing check in the brtopologychangedetection function allows a topology change timer to be armed while a bridge is administratively down. This can be exploited by an attacker to trigger a use-after-free...

CVE-2026-74269

A flaw was found in the bnxt driver, a component of the Linux kernel responsible for network card operations. This vulnerability involves a memory corruption issue that occurs during specific network data processing XDP head-grow operations. An underflow in the driver's code can lead to incorrect...
