CVE-2023-53331

Summary (CVE-2023-53331) : In the Linux kernel, the pstore/ram path could treat an empty prz as valid during init, allowing a start value equal to zero to bypass bounds checks and trigger out-of-bounds writes, potentially causing panics in multiple code paths (e.g., sysdump_panic_event, panic, do...

UBUNTU-CVE-2025-39836

In the Linux kernel, the following vulnerability has been resolved: efi: stmm: Fix incorrect buffer allocation method The communication buffer allocated by setupmmhdr is later on passed to teeshmregisterkernelbuf. The latter expects those buffers to be contiguous pages, but setupmmhdr just uses...

DEBIAN-CVE-2025-39816

In the Linux kernel, the following vulnerability has been resolved: iouring/kbuf: always use READONCE to read ring provided buffer lengths Since the buffers are mapped from userspace, it is prudent to use READONCE to read the value into a local variable, and use that for any other actions taken...

CVE-2025-39836

CVE-2025-39836 is a Linux kernel issue described as resolved: the EFI stmm path allocated a communication buffer with kmalloc(), while the consumer expects contiguous pages, risking corruptions/BUGs. The fix switches from kmalloc() to alloc_pages_exact() in setup_mm_hdr() so buffers passed to tee...

CVE-2025-39816

CVE-2025-39816 pertains to the Linux kernel’s io_uring/kbuf path. The issue stems from reading ring-provided buffer lengths without a stable read, risking changes between checks and commits since buffers come from userspace. The fix mandates using READ_ONCE() when reading these lengths and tighte...
