CVE-2026-80896 mshv: Fix race in mshv_irqfd_deassign

In the Linux kernel, the following vulnerability has been resolved: mshv: Fix race in mshvirqfddeassign mshvirqfddeactivate and the hlist traversal of ptirqfdslist require pt-ptirqfdslock to be held, but mshvirqfddeassign omits it. This races with the EPOLLHUP path in mshvirqfdwakeup, which does...

CVE-2026-80896

CVE-2026-80896 affects the mshv (Microsoft Hyper-V) component of the Linux kernel . The root cause is a race condition in mshv_irqfd_deassign(): it traverses pt_irqfds_list without holding the required pt->pt_irqfds_lock spinlock, racing with the EPOLLHUP path in mshv_irqfd_wakeup(). A second ...

CVE-2026-84947

undici's dump interceptor reads and discards a response body up to a configurable maximum size. When a response declares a Content-Length that exceeds the maximum, the interceptor aborts cleanly, but when a response has no Content-Length and is chunked, the interceptor instead signals completion...

CVE-2026-80851

In the Linux kernel, the following vulnerability has been resolved: gtp: serialize PDP context updates PDP contexts can be deleted through GTPCMDDELPDP or while the GTP network device is being unregistered. The latter is serialized by RTNL, but the generic-netlink delete path only holds RCU...

CVE-2026-80851

CVE-2026-80851 is a race condition in the Linux kernel's GTP (GPRS Tunnelling Protocol) module . PDP contexts could be double-deleted when the generic-netlink delete path (GTP_CMD_DELPDP) and GTP device unregistration (RTM_DELLINK) ran concurrently, since the former holds only RCU while the latte...

CVE-2026-80851 gtp: serialize PDP context updates

In the Linux kernel, the following vulnerability has been resolved: gtp: serialize PDP context updates PDP contexts can be deleted through GTPCMDDELPDP or while the GTP network device is being unregistered. The latter is serialized by RTNL, but the generic-netlink delete path only holds RCU...

CVE-2026-80807 nilfs2: reject invalid block index in GC ioctl

In the Linux kernel, the following vulnerability has been resolved: nilfs2: reject invalid block index in GC ioctl Syzbot reported list corruption caused by a double listaddtail call on bh-bassocbuffers within nilfslookupdirtydatabuffers. Analysis revealed that the root cause was the insertion of...

RUSTSEC-2026-0292 Double free / use-after-free in `Chunk` and `InlineArray` removal methods when an element's `Drop` panics

Chunk::clear, dropleft, dropright and InlineArray::clear, truncate drop the removed elements before updating the metadata that records which slots hold live values — the left/right index pair for Chunk, the length field for InlineArray. If an element's Drop panics during the drop, that update is...

CVE-2026-45200

Software installed and run as a non-privileged user may conduct improper GPU driver IOCTL calls to create an allocation scenario that when freed would cause double free and kernel heap corruption. Scenario caused by fabricating a specific combination of flags on the allocation interface that woul...

CVE-2026-45200

The GPU DDK is vulnerable to a double free and subsequent kernel heap corruption (CVE-2026-45200). The issue resides in the _FreeOSPages function, which can be triggered when _EncodeAllocationFlags sets an incorrect allocation flag. A non-privileged user can exploit this by conducting improper GP...
