CVE-2026-45903

A flaw was found in the Linux kernel's Berkeley Packet Filter BPF verifier. This vulnerability occurs because several BPF helper functions lack proper memory access flags, such as MEMRDONLY or MEMWRITE. Consequently, the verifier may incorrectly assume that buffer contents remain unchanged across...

CVE-2026-45903

CVE-2026-45903 concerns the Linux kernel BPF verifier and helper prototypes. The issue arises because several helpers using ARG_PTR_TO_MEM lacked MEM_RDONLY or MEM_WRITE flags, causing the verifier to incorrectly assume buffers are unchanged across calls and potentially optimize away subsequent r...

CVE-2026-43486

The CVE-2026-43486 entry details a Linux kernel arm64 contpte vulnerability where contpte_ptep_set_access_flags() could return a no-op when the gathered ptep_get() view matched the entry, leaving a sub-PTE with PTE_RDONLY or lacking PTE_AF in hardware. This could cause infinite fault loops for pa...
