CVE-2026-74674

CVE-2026-74674 is a Linux kernel vulnerability in the memory management (mm) subsystem, specifically in the zap_pte_range function. When reclaiming a page table, the kernel calls pte_free_tlb with an addr parameter that always points one past the end of the range covered by the table. This causes...

CVE-2026-74672

CVE-2026-74672 is a use-after-free vulnerability in the Linux kernel affecting both x86 and arm64 architectures. The root cause is a race condition between the ptdump page table walker and the vmap huge page table promotion logic: vmap frees lower page tables when promoting to huge leaf entries w...

CVE-2026-74644

CVE-2026-74644 affects the Linux kernel in the DAMON (Data Access Monitoring) subsystem, specifically in mm/damon/ops-common. When damon_pa_migrate() or damos_va_migrate() is called with an invalid target_nid (including the scheme default NUMA_NO_NODE / -1), damon_migrate_pages() returns early wi...

CVE-2026-74602 ring-buffer: Initialise reader page order in rb_allocate_cpu_buffer()

In the Linux kernel, the following vulnerability has been resolved: ring-buffer: Initialise reader page order in rballocatecpubuffer In rballocatecpubuffer, bpage-order was omitted, leaving it as 0. This is an issue for a ring-buffer with subbufs bigger than PAGESIZE if when freed: freebufferpage...

CVE-2026-74602

CVE-2026-74602 is a Linux kernel vulnerability in the ring-buffer subsystem. In rb_allocate_cpu_buffer(), the field bpage->order was left uninitialized (defaulting to 0). This becomes a problem when a ring-buffer uses subbuffers larger than PAGE_SIZE, because free_buffer_page() relies on the c...
