CVE-2026-31654

CVE-2026-31654 affects the Linux kernel mm/vma path for mmap-backed shared mappings (notably /dev/zero). The root cause was a memory leak: when __mmap_new_vma() fails after shmem_zero_setup_desc() allocates a replacement shmem file, that new file isn’t released in the error path, leaving an unref...

CVE-2026-31644

CVE-2026-31644 affects the Linux kernel LAN966X network driver. The issue arises in lan966x_fdma_reload() when allocation of new RX buffers fails, causing the restore path to restart DMA with old descriptors whose pages were already freed, and because page_pool_put_full_page() can release pages b...

CVE-2026-31640

CVE-2026-31640 affects the Linux kernel rxrpc component. The issue occurs in rxrpc_post_response() where the code compares the challenge serial number using the newer packet private data instead of the cached/older response, causing the comparison to always be false and potentially preventing the...
