  • kernel: scsi: qedi: Fix crash while reading debugfs attribute (CVE-2024-40978)

  • kernel: tipc: force a dst refcount before doing decryption (CVE-2024-40983)

  • kernel: ppp: reject claimed-as-LCP but actually malformed packets (CVE-2024-41044)

  • kernel: Revert "mm/writeback: fix possible divide-by-zero in wb_dirty_limits(), again" (CVE-2024-42102)
