In the Linux kernel, the following vulnerability has been resolved: tipc: fix divide-by-zero in tipcskfilterconnect A user can set conntimeout to any value via setsockoptTIPCCONNTIMEOUT, including values less than 4. When a SYN is rejected with TIPCERROVERLOAD and the retry path in...

CVE-2026-44498 ZEBRA: Block Validator Undercounts Coinbase and P2SH Sigops

ZEBRA is a Zcash node written entirely in Rust. Prior to version 4.4.0, Zebra's block validator undercounts transparent signature operations against the 20000-sigop block limit MAXBLOCKSIGOPS, allowing it to accept blocks that zcashd rejects with bad-blk-sigops. A miner who produces such a block...

CVE-2026-43428

CVE-2026-43428 affects the Linux kernel USB core. The vulnerability arises from usb_control_msg(), usb_bulk_msg(), and usb_interrupt_msg() allowing unbounded, uninterruptible timeouts, which could hang a task indefinitely. The fix enforces a maximum timeout of 60 seconds and treats negative timeo...

CVE-2026-43408

CVE-2026-43408 concerns the Linux kernel Ceph path handling: a missing zero-initialization of ceph_path_info before ceph_mdsc_build_path() calls can lead to crashes when ceph_mdsc_free_path_info() is invoked on error paths. Multiple code paths lacked proper initializers; the recommended fix is to...
