EUVD-2026-64350

In the Linux kernel, the following vulnerability has been resolved: net/sched: reject overly deep qdisc hierarchies Deep qdisc hierarchies can lead to excessive recursion in qdisc tree walkers and exhaust the kernel stack. The existing loop check does not cover the create-and-graft path, so a...

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-2026-74655 serial: qcom-geni: fix TX DMA buffer flush

In the Linux kernel, the following vulnerability has been resolved: serial: qcom-geni: fix TX DMA buffer flush When transmit flushing a qcom-geni UART during an ongoing TX DMA, the UART gets stuck infinitely repeating corrupted TX DMA frames. The DMA-mode uartops does not provide a flushbuffer...

EUVD-2026-64570

In the Linux kernel, the following vulnerability has been resolved: tracing: Fix NULL pointer dereference in module event cache removal A module-only event filter such as ":mod:foo" is cached with a NULL eventmod-match when foo has not been loaded. If a later write tries to remove a specific matc...

CVE-2026-74626

CVE-2026-74626 affects the NTB (Non-Transparent Bridge) network device driver in the Linux kernel. The root cause is in ntb_netdev_rx_handler(), which hands the received skb to the network stack before allocating its replacement. If the allocation fails, no buffer is reposted, so each failure per...

CVE-2026-74626 NTB: ntb_netdev: Preserve RX queue depth on allocation failure

In the Linux kernel, the following vulnerability has been resolved: NTB: ntbnetdev: Preserve RX queue depth on allocation failure ntbnetdevrxhandler hands the received skb to the network stack before allocating its replacement. If the allocation fails, nothing is reposted. Every failure therefore...

EUVD-2026-64562

In the Linux kernel, the following vulnerability has been resolved: netfilter: bridge: release template ct on non-IP path A bridge nftables ct zone set rule can attach a conntrack template to an skb before nfctbridgepre sees it. For non-IPv4 and non-IPv6 EtherTypes, nfctbridgepre currently...

CVE-2026-74620

This Linux kernel vulnerability affects the net/sched subsystem, specifically the act_gact and act_police traffic control actions. The fallback control actions (TCA_GACT_PROB.paction and TCA_POLICE_RESULT) bypass the range check in tcf_action_check_ctrlact(), allowing user space to store TC_ACT_C...

CVE-2026-74619

This Linux kernel vulnerability affects the overlayfs component. An unprivileged task can trigger a WARN_ON() in ovl_fill_super() by creating a user and mount namespace in a child process, calling fsopen("overlay"), passing the fscontext file descriptor to the parent, and having the parent issue ...

EUVD-2026-64556

In the Linux kernel, the following vulnerability has been resolved: ovl: don't warn when the mount is completed from another user namespace fsopen records the caller's user namespace in fc-userns and hands back an ordinary file descriptor. Nothing ties the task that calls fsconfigFSCONFIGCMDCREAT...

CVE-2026-74618

CVE-2026-74618 affects the Linux kernel 's binfmt_misc filesystem. The root cause is a WARN_ON() in bm_fill_super() that triggers when a binfmt_misc mount is completed from a different user namespace than the one that created the fscontext via fsopen(). Because fsconfig(FSCONFIG_CMD_CREATE) autho...

CVE-2026-74618 binfmt_misc: don't warn when the mount is completed from another user namespace

In the Linux kernel, the following vulnerability has been resolved: binfmtmisc: don't warn when the mount is completed from another user namespace fsopen records the caller's user namespace in fc-userns and hands back an ordinary file descriptor. Nothing ties the task that calls...

CVE-2026-74600

This vulnerability affects the Linux kernel in the mm/page_table_check subsystem. The functions page_table_check_set() and page_table_check_clear() account mappings based on PageAnon(), but shared zero-page PTEs and huge zero PMDs are special mappings that can be incorrectly accounted as file-bac...

EUVD-2026-64537

In the Linux kernel, the following vulnerability has been resolved: mm/pagetablecheck: skip special zero mappings pagetablecheckset and pagetablecheckclear account mappings based on PageAnon. Shared zero-page PTEs and huge zero PMDs are special mappings, but pagetablecheck can still account them ...

CVE-2026-74600 mm/page_table_check: skip special zero mappings

In the Linux kernel, the following vulnerability has been resolved: mm/pagetablecheck: skip special zero mappings pagetablecheckset and pagetablecheckclear account mappings based on PageAnon. Shared zero-page PTEs and huge zero PMDs are special mappings, but pagetablecheck can still account them ...

CVE-2026-74590

CVE-2026-74590 is a memory-safety flaw in the Linux kernel 's fsverity subsystem, specifically in the bpf_get_fsverity_digest() kfunc. The BPF verifier and dynptr abstraction guarantee memory-space validity but not content stability; kfuncs are expected to remain safe under concurrent modificatio...
