CVE-2026-74628

A flaw was found in the Linux kernel's x25 network protocol. The way timers are managed for x25 sockets can lead to a use-after-free vulnerability. Specifically, a timer might be rearmed after the associated socket has been deallocated, causing the system to access freed memory. This could...

CVE-2026-74602

A flaw was found in the Linux kernel's ring-buffer component. The rballocatecpubuffer function failed to initialize the bpage-order value, leaving it as zero. This uninitialized value is later used by freebufferpage when deallocating ring-buffers with sub-buffers larger than a page size. An...

CVE-2026-74325

A flaw was found in the wifi: mt76 driver within the Linux kernel. This vulnerability occurs because the mt76putvifphylink function improperly deallocates memory for offchannel links. An attacker could exploit this by causing the system to access memory after it has been freed, leading to a...

CVE-2026-72145

A flaw was found in the Linux kernel's platform/x86/intel/tpmi component. This vulnerability occurs due to improper memory deallocation within the memwrite function, where a temporary array was not consistently released on all exit paths. This could lead to a memory leak, potentially impacting...

CVE-2026-68218

A flaw was found in the dm1105 PCI driver of the Linux kernel. This issue arises from the driver's failure to properly deallocate resources, specifically a workqueue, when the device is removed. This oversight can lead to a memory leak, which a local attacker could potentially exploit to cause a...

CVE-2026-68305

A flaw was found in the Linux kernel's Direct Rendering Manager DRM subsystem. This vulnerability arises when graphics buffer objects are deallocated prematurely while the DRM structure remains active. This can lead to a null pointer dereference when the system attempts to access these freed...
