CVE-2026-81008

CVE-2026-81008 is a slab use-after-free in the Linux kernel's interconnect subsystem, affecting icc_get() and of_icc_get_by_index(). When kasprintf() fails to allocate path->name, the error path calls kfree(path) directly, leaving dangling pointers in the req_list hlists that were already popu...

CVE-2026-81007

CVE-2026-81007 affects the Linux kernel 's ipmi/ipmb subsystem. The function ipmb_write() read message fields before validating the length byte, allowing a zero or short write to read uninitialized stack bytes and causing an integer underflow in the block write length when the length is smaller t...

CVE-2026-81006

CVE-2026-81006 is a memory corruption flaw in the Linux kernel's IPMI subsystem. The function ipmi_add_smi() creates the nr_users and nr_msgs sysfs files before attempting to create the maintenance_mode file. If the last creation fails, the error path removes only nr_users before dropping the fin...

CVE-2026-81005

CVE-2026-81005 affects the Linux kernel IPMI SI driver (ipmi_si). When BMC registration fails—typically because the BMC does not return a successful response to the Get Device ID command—the shutdown_smi() callback frees the si_sm pointer and sets it to NULL , but the intf->in_shutdown flag is...

CVE-2026-81004

CVE-2026-81004 affects the Linux kernel's IPMI message handler (ipmi:msghandler). When an error occurs during the startup of an IPMI interface, scheduled work may not be properly canceled before the interface is freed, which can prevent clean resource release and potentially lead to resource exha...

CVE-2026-81003

CVE-2026-81003 affects the Linux kernel net/iucv subsystem (IBM s390 IUCV/HiperSockets). The function afiucv_hs_rcv() matched incoming frames to sockets using only four 8-byte name fields in the transport header, without verifying the ingress net_device . This allowed frames from any network devi...

CVE-2026-81002

CVE-2026-81002 is a critical (CVSS 9.8) memory corruption flaw in the Linux kernel's XDP component. The xdp_convert_zc_to_xdp_frame() function clones an AF_XDP zero-copy packet into an order-0 page but incorrectly advertises PAGE_SIZE as the frame size, allowing the frame to overlap skb_shared_in...

CVE-2026-81000

CVE-2026-81000 affects the Linux kernel TUN/TAP driver . The root cause is an integer underflow in tun_get_user(): when Open vSwitch (OVS) propagates an oversized headroom request from another port, SKB_MAX_HEAD(align) underflows, causing tun_alloc_skb() to place skb->data outside the allocate...

CVE-2026-81001

A use-after-free race condition exists in the Linux kernel's SLIP (Serial Line Internet Protocol) driver , specifically in sl_sync() (drivers/net/slip/slip.c). The slip_devs[] table stores bare net_device pointers without reference counting. Because netdev_run_todo() drops the RTNL lock before ca...

CVE-2026-80999

CVE-2026-80999 affects the Linux kernel 's Realtek DSA driver (net: dsa: realtek). The root cause is that rtl83xx_reset_assert() and rtl83xx_reset_deassert() invoke the non-sleeping gpiod_set_value() for the reset GPIO. When that GPIO is backed by a sleeping controller such as an I2C I/O expander...

CVE-2026-80998

CVE-2026-80998 affects the Linux kernel's bnxt network driver. When the Software UDP Segmentation Offload (SW USO) path (bnxt_sw_udp_gso_xmit) returns early with NETDEV_TX_BUSY while txr->kick_pending is set, the driver writes buffer descriptors but never rings the hardware doorbell , causing ...

CVE-2026-80997

A race condition in the Linux kernel's IP Accelerator (IPA) network driver can cause a permanent transmit (TX) queue stall after a runtime resume. The function ipa_start_xmit() stops the TX queue and relies on a work item (ipa_modem_wake_queue_work()) to restart it, but that work is queued before...

CVE-2026-80996

CVE-2026-80996 affects the Linux kernel 's L2TP (Layer 2 Tunneling Protocol) subsystem. The tunnel create, tunnel modify, session create, and session modify netlink handlers send multicast notifications through helpers that can fail during message allocation, encoding, or multicasting. Because th...

CVE-2026-80995

A use-after-free vulnerability in the Linux kernel's MCTP (Message Control Transport Protocol) networking stack. The mctp_route_lookup() function accesses a route's device (rt->dev) without holding a persistent reference, allowing concurrent deallocation via mctp_dev_put() → kfree(). A subsequ...

CVE-2026-80994

CVE-2026-80994 is a use-after-free vulnerability in the Linux kernel's Open vSwitch (OVS) datapath . During flow deletion (CMD_DEL), the flow mask is freed via RCU after removal from the flow table, but ovs_flow_cmd_fill_info() subsequently dereferences the flow->mask pointer without effective...

CVE-2026-80993

CVE-2026-80993 affects the Linux kernel in the net: phylink subsystem. In the function phylink_inband_caps() , the PCS returned by mac_select_pcs() was only validated against NULL , but the function can also return an error pointer . This causes a kernel panic because phylink_pcs_inband_caps() di...

CVE-2026-80992

CVE-2026-80992 is a NULL pointer dereference in the Linux kernel's net: ravb (RENESAS AVB Ethernet) driver. The PTP clock is unavailable before the first open, so querying its index can dereference a NULL pointer; registration failures can also leave an error pointer in priv->ptp.clock. Red Ha...

CVE-2026-80991

A race condition in the Linux kernel's net: ravb Ethernet driver can lead to a use-after-free during PTP clock teardown. Specifically, ravb_ptp_interrupt() can race with ravb_ptp_stop(), passing the PTP clock to ptp_clock_event() while ptp_clock_unregister() is freeing it. The fix serializes tear...

CVE-2026-80990

CVE-2026-80990 is a resource-leak bug in the Linux kernel Thunderbolt networking (tbnet ) subsystem. In tbnet_connected_work(), the function requests a specific Rx HopID from tb_xdomain_alloc_in_hopid(), which uses ida_alloc_range() with the desired ID as a lower bound. If the requested ID is alr...

CVE-2026-80989

CVE-2026-80989 affects the Linux kernel Thunderbolt networking subsystem (net: thunderbolt). When a Thunderbolt connection fails to establish, failure paths in tbnet_connected_work() fail to clear the login_sent state, leaving the connection appearing established. A subsequent tbnet_tear_down() t...
