CVE-2026-64561

A flaw was found in KVM in the Linux kernel. This vulnerability occurs due to improper validation of memory management unit MMU page roots after these pages are made available. An attacker could exploit this by triggering a scenario where KVM attempts to map memory into an invalid root, causing...

EUVD-2026-52602

In the Linux kernel, the following vulnerability has been resolved: KVM: x86: Check for invalid/obsolete root after making MMU pages available Check for a "stale" page fault, i.e. for an invalid and/or obsolete root, after making MMU pages available for the shadow MMU. If reclaiming shadow pages...

CVE-2026-64561

CVE-2026-64561 is a Linux kernel KVM/x86 vulnerability related to the shadow MMU; after MMU pages are made available, reclaiming a zapped in-use root can lead to mapping memory into an invalid root, violating the invariant that invalid pages are not on the active MMU page list. The flaw has histo...

Flattening of vulnerability handling in SQLite through the SQLite Consortium

The SQLite Consortium has identified a vulnerability in SQLite version 3.41. This vulnerability relates to the expression evaluation logic of SQLite. An attacker can exploit this vulnerability remotely by submitting specially crafted malicious SQL statements. Exploitation may result in the...

CVE-2026-64416

A flaw was found in the Linux kernel's memory management subsystem, specifically within the swap cgroup functionality. When a system is configured without swap, a corrupted page table entry PTE can lead to a null pointer dereference during process exit. This vulnerability allows a local attacker ...

CVE-2026-64282

A flaw was found in the Linux kernel's KVM Kernel-based Virtual Machine for arm64 architectures. A race condition between the kvmtranslatevncr function and an MMU Memory Management Unit notifier can lead to a Page Frame Number PFN leak. This occurs because an early return in kvmtranslatevncr fail...

CVE-2026-64419

A flaw was found in the Linux kernel. A local user could trigger a system crash by reading a specific debugfs "count" file related to memory management. This issue arises because a function attempts to perform an operation that can cause it to pause sleep while holding a critical system lock, whi...

CVE-2026-64295

A flaw was found in the Linux kernel's memory management mm component, specifically within the pageext iteration application programming interface API. When memory is dynamically added to the system a process known as 'hotplugging', the API does not properly validate memory page frame numbers PFN...

CVE-2026-64415

A flaw was found in the Linux kernel's memory management mm/swap component. Under heavy memory and swap stress, a local attacker could trigger a softlockup during large swap cluster reclaim operations. This vulnerability can lead to a Denial of Service DoS, making the system unresponsive...

CVE-2026-64514

A flaw was found in the Linux kernel's userfaultfd mechanism. This vulnerability occurs when the userfaultfdmustwait and userfaultfdhugemustwait functions incorrectly read Page Table Entries PTEs without proper locking during memory operations. This can lead to an undefined state if a page is bei...

CVE-2026-64294

A flaw was found in the Linux kernel's memory management subsystem. This vulnerability arises from incorrect handling of file ownership checks within idmapped mounts, a feature that allows remapping user and group IDs. When certain memory operations are performed on files in an idmapped mount, th...

PT-2026-65897

Name of the Vulnerable Software and Affected Versions mcp versions prior to 0.23.0 Description The MCP::Server::Transports::StreamableHTTPTransport component in the mcp gem does not expire sessions by default. Consequently, repeated initialize requests lead to the retention of unbounded...

CVE-2026-62434

A guest started with Populated on Demand enabled PoD can attempt to reclaim pages which aren't regular guest RAM. This can cause corruption of memory management state in Xen...

PoD: Don't try to reclaim special pages

ISSUE DESCRIPTION A guest started with Populated on Demand enabled PoD can attempt to reclaim pages which aren't regular guest RAM. This can cause corruption of memory management state in Xen. IMPACT A buggy or malicious guest can cause corruption of Xen's state, leading to crashes or other...

CVE-2026-64244

A flaw was found in the Linux kernel's memory management. This vulnerability occurs when a memory block fails to register, but its associated memory map is not properly cleared during device removal. This can lead to a system warning and potential instability or a kernel crash, allowing a local...

CVE-2026-51300

A flaw was found in SQLite. This use-after-free vulnerability exists in the expression parsing and memory management logic. A remote attacker can exploit this by crafting malicious SQL queries, which leads to invalid memory access. This can result in an application crash and the leakage of...
