CVE-2026-98255

The Linux kernel contains a vulnerability where old Acknowledgements (ACKs) could bypass the fast path of the TCP stack. Specifically, ACKs before SND.UNA and after SND.NXT were not being properly validated, potentially allowing them to modify connection state or advance RCV.NXT prematurely. The ...

EUVD-2026-93183

In the Linux kernel, the following vulnerability has been resolved: tcp: exclude old ACKs from tcp fast path Exclude old ACKs before SND.UNA from the tcp fast path as well as ACKs after SND.NXT. Such ACKs will fall through to the slow path, where tcpack performs the appropriate validation and...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: xfrm: ESP: restoring the combined single-frag-length gate. The ESP out-of-place fast path appends the trailer in espoutputhead, before espoutputtail allocates the destination page frag. Currently, the head-side gate checks...

EUVD-2026-70107

The X-mount.subdir option uses a detached-tree fast path on Linux 6.15 and later and passes the configured subdirectory to opentree with ATSYMLINKNOFOLLOW. That flag does not stop intermediate symlink traversal or keep resolution inside the newly mounted filesystem. A local unprivileged user with...

CVE-2026-74658 futex: Prevent robust futex exit race some more

In the Linux kernel, the following vulnerability has been resolved: futex: Prevent robust futex exit race some more A robust futex unlock stores 0 over the whole futex value - wiping FUTEXWAITERS - and wakes a single waiter. That wakeup is a one-shot notification: the protocol relies on its...

CVE-2026-64151

The CVE-2026-64151 entry concerns the Linux kernel iommupt component, where a driver could omit PAGE_SIZE from the pgsize_bitmap. The root cause is that removing PAGE_SIZE from the bitmap is technically allowed but would leave an iommu_domain unused with the DMA API; the design is violated. The d...
