CVE-2026-90217

This Linux kernel BPF verifier vulnerability (CVE-2026-90217) occurs because an iterator stack slot can hold either MEM_RCU or PTR_UNTRUSTED pointer types, and the verifier fails to distinguish them during state pruning, potentially pruning an unsafe path. The fix compares the pointer type for ST...

CVE-2026-90217 bpf: Compare iterator types during state pruning

In the Linux kernel, the following vulnerability has been resolved: bpf: Compare iterator types during state pruning An iterator stack slot can be MEMRCU or PTRUNTRUSTED. These states must not be equal, or the verifier can prune an unsafe path. Compare the pointer type for STACKITER slots...

CVE-2026-90183 blk-iolatency: clear delay state when freeing policy data

In the Linux kernel, the following vulnerability has been resolved: blk-iolatency: clear delay state when freeing policy data io.latency can throttle a group which has no latency target of its own. When a sibling misses its target, checkscalechange scales down its peers, and a peer that reaches...

CVE-2026-90182

CVE-2026-90182 affects the Linux kernel 's blk-iocost block-I/O cost cgroup controller. When ioc_pd_free() removes an iocg from active_iocgs and cancels its waitq timer, no further mechanism can reduce debt or clear the delay state previously set by iocg_kick_delay() (which sets blkg->use_dela...

CVE-2026-90182 blk-iocost: clear delay state when freeing policy data

In the Linux kernel, the following vulnerability has been resolved: blk-iocost: clear delay state when freeing policy data iocgkickdelay turns sufficiently large debt into an explicit block-cgroup delay with blkcgsetdelay, setting blkg-usedelay to -1 and incrementing blkcg-congestioncount. Cleari...

CVE-2026-90154

CVE-2026-90154 affects the ksmbd subsystem of the Linux kernel . The function ksmbd_all_conn_set_status() incorrectly treats every connection with a transient binding flag as belonging to the target SessionId, so a logoff or session replacement can move an unrelated connection to NEED_RECONNECT o...

CVE-2026-90067

CVE-2026-90067 is a Linux kernel vulnerability in the Ceph messenger v2 protocol implementation (net/ceph/messenger_v2.c). When parsing the msgr2 protocol banner, a client sending a payload_len of 0 causes the kernel to set up a 0-length socket read , violating a state-machine invariant and trigg...

CVE-2026-90062 netfilter: nf_tables: move hardware offload step after building the chain blob

In the Linux kernel, the following vulnerability has been resolved: netfilter: nftables: move hardware offload step after building the chain blob Allocate the chain blob before the ruleset offload to reduce chances of entering an inconsistent state where the offloaded ruleset in the nic and the...

CVE-2026-90062

CVE-2026-90062 is a vulnerability in the Linux kernel 's netfilter/nf_tables subsystem. The root cause is an ordering issue where the chain blob was allocated after the ruleset hardware offload, which could leave the offloaded ruleset in the NIC inconsistent with the software ruleset . The fix mo...
