CVE-2026-90101

CVE-2026-90101 affects the bnxt_en driver in the Linux kernel. The driver calls hwmon_notify_event() with the platform device as its first parameter instead of the expected hardware monitoring device . This API contract violation results in undefined behavior and may lead to a crash . The fix pas...

CVE-2026-90100

CVE-2026-90100 affects the Linux kernel PTP (Precision Time Protocol) netc driver. The root cause is a period truncation in net_timer_enable_perout(): a u64 max_period bound exceeds U32_MAX when integral_period > 0, allowing a period_ns value to pass the range check but be silently truncated t...

CVE-2026-90098

CVE-2026-90098 affects the Linux kernel sparx5 network driver. The root cause is that sparx5_set_rx_mode() executes with netif_addr_lock_bh held (an atomic context), yet calls sparx5_mact_learn() / sparx5_mact_forget() , which acquire a mutex and poll the MAC access command register via readx_pol...

CVE-2026-90099

CVE-2026-90099 affects the Linux kernel's net/sched (traffic control) subsystem. Allocations in tc classifier *_change() paths use GFP_KERNEL without __GFP_ACCOUNT , allowing unprivileged users in a user+network namespace to pin kernel memory outside memcg charging by creating large numbers of tc...

CVE-2026-90097

CVE-2026-90097 affects the Linux kernel Hyper-V VMBus driver . When running in the root partition (not nested in another VM), the hv_acpi_init() function performs no initialization yet reports success, causing the module to load in an uninitialized state. If the VMBus module is subsequently unloa...

CVE-2026-90095

CVE-2026-90095 affects the Linux kernel FUSE subsystem. The root cause is a missing condition in fuse_uring_cmd() that failed to refuse IORING_OP_URING_CMD when the FUSE_OVER_IO_URING flag was absent from the FUSE_INIT reply. Without this guard, the barrier in fuse_uring_ready() does not function...

CVE-2026-90096

CVE-2026-90096 affects the Linux kernel FUSE subsystem. In fuse_direct_write_iter(), the variable pos is captured before generic_write_checks(), which moves ki_pos to EOF for O_APPEND direct writes. The post-write page invalidation then targets a stale range [0, res) instead of the actual written...

CVE-2026-90094

CVE-2026-90094 affects the Linux kernel on arm64 systems, specifically in the process context-switching path for MTE (Memory Tagging Extension) store-only tag check mode. When a user opts in to store-only tag check via SCTLR_EL1.TCSO0 , that flag was not included in SCTLR_USER_MASK , meaning it w...

CVE-2026-90092

CVE-2026-90092 is a use-after-free vulnerability in the Linux kernel Bluetooth L2CAP subsystem. The root cause is a race condition between l2cap_sock_new_connection_cb() and the parent l2cap_chan teardown: when chan->state is accessed without consistent locking, a new socket can be added to th...

CVE-2026-90093

CVE-2026-90093 is a use-after-free bug in the Linux kernel Bluetooth L2CAP subsystem. Since commit b66774b48dd9, l2cap_chan::conn retains a reference that remains non-NULL even after the corresponding hci_conn is deleted. Accessing fields such as hci_conn::hdev in this state causes a KASAN crash ...

CVE-2026-90091

CVE-2026-90091 is a race condition in the Linux kernel's Bluetooth L2CAP subsystem. For L2CAP sockets that do not own sk->sk_socket, an unsafe lockless read of l2cap_pi(sk)->chan in l2cap_sock_cleanup_listen() can race against a concurrent l2cap_sock_kill() → l2cap_sock_put_chan(), which se...

CVE-2026-90089

This Linux kernel vulnerability affects the btnxpuart Bluetooth driver (NXP UART-based controllers). The function nxp_process_fw_dump() reads seq_num and buf_len from an 8-byte struct nxp_fw_dump_hdr at the start of the ACL payload without verifying that the payload is at least 8 bytes long. Sinc...

CVE-2026-90090

This CVE affects the Linux kernel Bluetooth btmtksdio driver. In the TX path, btmtksdio_tx_packet() rounds the transfer size up to the SDIO block size of 256 bytes but passes the raw SKB buffer to sdio_writesb(). Since only skb->len bytes hold actual packet data, the host controller reads up t...

CVE-2026-90088

CVE-2026-90088 affects the Linux kernel Bluetooth RFCOMM subsystem. The function rfcomm_apply_pn() accepts an MTU value from a remote Parameter Negotiation (PN) frame without validating it against zero. When a remote peer sends an MTU of zero, the sendmsg path enters an infinite loop during data ...

CVE-2026-90086

CVE-2026-90086 affects the Linux kernel AF_XDP (xsk) zero-copy TX path . The root cause is that the zero-copy path reads TX metadata whenever the UMEM has metadata space, even when the descriptor does not set the XDP_TX_METADATA flag. The fix passes descriptor options through the metadata helpers...

CVE-2026-90087

CVE-2026-90087 is a Linux kernel Bluetooth (HCI) resource leak affecting the handling of concurrent LE (BLE) connection attempts. When two connections are in BT_CONNECT simultaneously—specifically one on the passive scan path with HCI_CONN_SCANNING set—create_le_conn_complete() may match the wron...

CVE-2026-90085

CVE-2026-90085 affects the octeontx2-af driver in the Linux kernel . The function rvu_dbg_nix_tm_tree_display() dereferences pfvf->sq_ctx without verifying that the SQ context has been allocated. Reading /sys/kernel/debug/octeontx2/nix/tm_tree for a NIX logical function whose transmit queues a...

CVE-2026-90083

CVE-2026-90083 affects the Linux kernel's net/sched act_ife (IFE) traffic control action. The IFE action uses skb->dev->hard_header_len as the Ethernet header length, which is incorrect on non-Ethernet devices (e.g., PPP reports PPP_HDRLEN while nothing is stripped on ingress). When a packe...

CVE-2026-90084

CVE-2026-90084 affects the octeontx2-vf driver in the Linux kernel . A race condition exists in the probe/remove path: the VF workqueue was initialized after register_netdev(), meaning ndo_set_rx_mode could queue work on a NULL workqueue before initialization completed. The fix reorders the initi...

CVE-2026-90082

This CVE affects the Linux kernel mana network driver (Microsoft Azure Network Adapter). The root cause is an out-of-bounds access during MSI-X vector setup: mana_gd_query_max_resources() sizes the usable vector count from the reported maximum and CPU count but never caps it to the actual device ...
