CVE-2026-89490

CVE-2026-89490 affects the ocfs2 filesystem in the Linux kernel on 32-bit systems. In ocfs2_dir_foreach_blk_el(), the directory position mask derived from sb->s_blocksize (a 32-bit unsigned long) is zero-extended to 64 bits when ANDed with the loff_t-typed ctx->pos, silently clearing the hi...

CVE-2026-89488

CVE-2026-89488 is a slab-use-after-free in the Linux kernel's Open vSwitch (OVS) component, occurring during network namespace teardown . Packet processing reads CT (connection tracking) limit state under RCU, while teardown frees that state under ovs_mutex without removing the pointer from reade...

CVE-2026-89487

CVE-2026-89487 affects the openvswitch subsystem in the Linux kernel. The bug resides in queue_userspace_packet(), whose error path calls skb_tx_error() on a packet that is still being forwarded through remaining flow actions. This call strips SKBFL_SHARED_FRAG from the live skb via skb_zcopy_cle...

CVE-2026-89486

CVE-2026-89486 is a use-after-free vulnerability in the Linux kernel's IPMI subsystem , introduced by commit 9e91f8a6c868 which removed a synchronize_rcu() grace period before freeing command receiver (cmd_rcvr) objects in _ipmi_destroy_user(). Because the cmd_rcvrs list is still traversed under ...

CVE-2026-89485

CVE-2026-89485 is a use-after-free vulnerability in the Linux kernel's lockd (NLM) subsystem. In nlm_traverse_files(), the current file is pinned across a mutex_unlock window, but the saved next pointer is not. A concurrent nlm_release_file() can free that next file, causing the iterator to deref...

CVE-2026-89483

CVE-2026-89483 is an information disclosure flaw in the Linux kernel NVMe subsystem . When nvme_setup_discard() falls back to the per-controller ctrl->discard_page (allocated via alloc_page(GFP_KERNEL) without zeroing) under memory pressure, up to 4080 bytes of uninitialized kernel memory (inc...

CVE-2026-89484

CVE-2026-89484 is a NULL pointer dereference in the Linux kernel's lockd (Network Lock Manager) subsystem. The bug occurs when nlmclnt_find_lockowner() fails to allocate a lockowner, yet nlmclnt_locks_init_private() still installs NLM file lock operations. When the VFS subsequently tears down the...

CVE-2026-89482

CVE-2026-89482 is a wild-memory-access vulnerability in the Linux kernel's nvme-tcp module. The root cause is an incorrect receive-side gate: for REQ_OP_WRITE_ZEROES commands, blk_rq_payload_bytes() returns a non-zero value despite the absence of physical segments, so the setup phase leaves req-&...

CVE-2026-89481

CVE-2026-89481 affects the Linux kernel's NVMe over TCP (nvme-tcp) component. The root cause is that nvme_tcp_handle_r2t() does not validate the direction of the request a Ready to Transfer (R2T) refers to. A malicious NVMe controller can send an R2T for a READ command; the host then sends the co...

CVE-2026-89479

CVE-2026-89479 is a use-after-free in the Linux kernel's SCTP implementation. In sctp_endpoint_bh_rcv(), the association is cached in chunk->asoc and chunk->transport without holding a reference. A remote peer can bundle COOKIE ECHO, SHUTDOWN, and SHUTDOWN ACK in a single packet: the COOKIE...

CVE-2026-89480

CVE-2026-89480 affects the NVMe-TCP driver in the Linux kernel. The function nvme_tcp_recv_data() completes a read request once the current C2HData PDU is consumed, but no mechanism compares the total bytes received against the length requested by the command. A malicious or faulty NVMe controlle...

CVE-2026-89478

CVE-2026-89478 is a use-after-free in the Linux kernel's SCTP implementation. An authenticated attacker can send an ASCONF DEL-IP to remove a transport while a DATA chunk is still in flight (on the socket backlog or direct path). The chunk's lingering transport reference causes the transport to b...

CVE-2026-89476

CVE-2026-89476 affects the Linux kernel's SCTP (Stream Control Transmission Protocol) implementation. A cached RECONF chunk may contain multiple request parameters, so a duplicate response can re-process the same ADD_OUT request while another parameter is still outstanding, rolling back stream-&g...

CVE-2026-89477

CVE-2026-89477 is a NULL pointer dereference in the Linux kernel's SCTP stream reconfiguration code. When a reconfiguration request is queued in asoc->strreset_chunk but not yet transmitted, chunk->transport remains NULL; three completion functions (sctp_process_strreset_outreq, sctp_proces...

CVE-2026-89475

A use-after-free vulnerability in the Linux kernel's bq24257 power supply driver is triggered during device removal. The STAT-pin interrupt is devm-managed and stays armed until devm cleanup runs after remove() returns. While remove() cancels the iilimit_setup_work, the threaded interrupt handler...

CVE-2026-89474

CVE-2026-89474 is a use-after-free in the Linux kernel's bq256xx power supply driver. On driver removal, the USB-PHY notifier queues a work item (usb_work) whose handler calls power_supply_changed(bq->charger). Because the reset devm action was registered before the power supplies, the devm un...

CVE-2026-89473

This Linux kernel vulnerability affects the bq25890 charger driver in the power supply subsystem. The function bq25890_fw_probe() acquires a reference to a secondary charger via power_supply_get_by_name(), but the reference is not released on subsequent probe failures (e.g., failure in bq25890_hw...

CVE-2026-89472

CVE-2026-89472 is a use-after-free vulnerability in the Linux kernel's power supply charger-manager driver. The root cause is a race condition in the device removal and probe-error paths: charger regulators are freed via regulator_put() before the corresponding power_supply sysfs entries are unre...

CVE-2026-89470

A vulnerability in the Linux kernel's cros_usbpd-charger driver (power supply / USB power delivery) allows a malicious embedded controller to return an exaggerated charger port count (up to 255) that is not bounded by EC_USB_PD_MAX_PORTS , resulting in an out-of-bounds write and subsequent memory...

CVE-2026-89471

CVE-2026-89471 affects the Linux kernel cros_usbpd-charger driver (power supply subsystem). The driver uses an EC-reported num_charger_ports value as a loop bound for an 8-entry fixed-size array (ports[EC_USB_PD_MAX_PORTS]) without validating it against the array size. A malicious or malfunctioni...
