OliveTin: Unauthenticated DoS via OAuth2 State Memory Exhaustion (Unbounded Map Growth)

Summary OliveTin's OAuth2 login handler stores per-login state in an in-memory map registeredStates that grows unboundedly. States are added on every /oauth/login request but are never deleted or expired. An unauthenticated attacker can send millions of requests to /oauth/login to fill the map wi...

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...

In the Linux kernel, the following vulnerability has been resolved: x86/mm: Fix freeing of PMD-sized vmemmap pages Commit bf9e4e30f353 "x86/mm: use pagetablefree", switched from freeing non-boot page tables through freepages to pagetablefree. However, the function is also called to free vmemmap...

SUSE CVE-2026-64244

In the Linux kernel, the following vulnerability has been resolved: drivers/base/memory: set mem-altmap after successful device registration If addmemoryblock fails at xastore under memory pressure for example, deviceunregister is called, which eventually triggers memoryblockrelease with mem-altm...

CVE-2026-65068 Data::SpatialHash::Shared versions before 0.02 for Perl create a world-readable mmap backing file and open it without O_EXCL or O_NOFOLLOW

Data::SpatialHash::Shared versions before 0.02 for Perl create a world-readable mmap backing file and open it without OEXCL or ONOFOLLOW. The segment is created in sphash.h with openpath, ORDWR|OCREAT, 0666. The mode is 0666, so under the default umask 022 the file is created mode 0644...

CVE-2026-64064

In the Linux kernel, the following vulnerability has been resolved: netfs: Fix netfsinvalidatefolio to clear dirty bit if all changes gone If a streaming write is made, this will leave the relevant modified folio in a not-uptodate, but dirty state with a netfsfolio struct hung off of folio-privat...

CVE-2026-64008

The CVE-2026-64008 issue affects the Linux kernel’s accel/rocket path. rocket_ioctl_create_bo() creates a GEM handle early via drm_gem_handle_create(), then proceeds through fallible steps (sgt allocation, drm_mm insert, iommu_map). If any step fails after the handle is live, the error path frees...
