CVE-2026-55571 djust authentication bypass: a login_required / on_mount LiveView mount redirect does not close the WebSocket, allowing an unauthenticated client to dispatch event-handler calls

djust provides Phoenix LiveView-style reactive server-side rendering for Django with Rust-powered performance. Prior to 1.0.4, LiveViewConsumer.handlemount sends a "type":"navigate","to":... frame when loginrequired, permissionrequired, or a redirecting onmount hook denies a LiveView mount, but...

CVE-2026-13478 Out-of-bounds read in Zephyr ext2 block-bitmap validation from a crafted s_blocks_count

The Zephyr ext2 filesystem driver validates the on-disk block bitmap in ext2initfs subsys/fs/ext2/ext2impl.c by passing fsblocks = sblockscount - sfirstdatablock to ext2bitmapcountset. That helper subsys/fs/ext2/ext2bitmap.c treats its argument as a number of bits and reads one bitmap byte per...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: ntfs: Freeing volume-wide resources upon a fillsuper failure The erroutnow path in ntfsfillsuper only frees the volume struct via kfreevol. Several resources owned by the volume are left behind upon each mount failure: -...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: binfmtmisc: Do not leak the user namespace when the mount fails. The bmgettree function takes a reference to the user namespace and passes it to gettreekeyed as the sget key. sgetfc moves this reference to sb-sfsinfo and clear...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: fhandle: Detached mounts are now rejected in capablewrtmount. The recent RCU fix moved the mount namespace capability check to capablewrtmount, so a non-NULL mntnamespace remains valid after the nscapable dereference. The helper...
