CVE-2026-74409

Summary : The CVE-2026-74409 issue resides in the Linux kernel wifi driver for RTW89. An 8‑bit mac_id in RX descriptors (0–255) can index into assoc_link_on_macid[] which has only 128 entries (RTW89_MAX_MAC_ID_NUM). Firmware-supplied mac_id values are not validated before use as an array index, a...

CVE-2026-74408

The Linux kernel WiFi driver ath9k has a vulnerability (CVE-2026-74408) where ath_tx_edma_tasklet() accesses sc->tx.txq[ts.qid] with ts.qid being a 4-bit field (0-15) while the txq array supports only ATH9K_NUM_TX_QUEUES (10). A qid of 10 or higher causes an out-of-bounds access. The documente...

CVE-2026-74407

In the Linux kernel, CVE-2026-74407 impacts PCI/MHI-based ath11k WLAN: during shutdown, SSR (WLAN firmware crash recovery) can race with teardown, leading to a NULL pointer dereference in the MHI teardown path while freeing DMA-backed contexts. The fix is to cancel SSR-related work items during P...

CVE-2026-74406

The CVE-2026-74406 entry relates to the Linux kernel, fixing a potential null-ptr-deref in vxlan_gro_prepare_receive() where udp_tunnel_sock_release() could clear sk->sk_user_data during execution. The issue involves a race with skb_gro_remcsum_init() and rcu_dereference_sk_user_data(). Affect...

CVE-2026-74404

The CVE-2026-74404 issue affects the Linux kernel crypto/ccp path where snp_filter_reserved_mem_regions() bounds check could lead to an off-by-one heap overflow when constructing the iomem reservation descriptor. Specifically, for range_list->num_elements up to 255, (num_elements * 16 + 8) can...

CVE-2026-74405

The CVE-2026-74405 issue affects the Linux kernel OPP handling. A race between dev_pm_opp_add_dynamic() and dev_pm_opp_find_freq_exact() could expose a newly added OPP before its kref and opp_table were initialized, allowing a concurrent lookup to increment the reference count on an uninitialized...

CVE-2026-74403

The CVE-2026-74403 entries describe a Linux kernel fix in crypto: ccp where a NULL page allocation could lead to a non-NULL garbage from page_address(NULL) on architectures without HASHED_PAGE_VIRTUAL. The root cause is passing a potentially NULL page pointer to page_address() and then evaluating...

CVE-2026-74402

Summary (CVE-2026-74402) : In the Linux kernel, the crypto driver for the Atmel SHA204A RNG had a bug in both blocking and non-blocking paths where entropy was not properly fed due to incorrect buffer management, causing reads to return partial or incorrect data. The issue manifested as reading 3...

CVE-2026-74401

In the Linux kernel, CVE-2026-74401 relates to the DLM path: the mh->seq ordering in the send_queue was not enforced, potentially causing refcounting issues and use-after-free in high-throughput DLM messaging scenarios. The fix adds correct ordering in the send_queue so that older sequence num...

CVE-2026-74400

CVE-2026-74400 affects the Linux kernel: bpf_set_dentry_xattr and bpf_remove_dentry_xattr kfuncs may crash when given negative dentries because d_inode(dentry) can be NULL, leading to inode_lock(NULL). The fix adds a NULL check for the inode and returns -EINVAL when NULL. The patch also removes a...

CVE-2026-74399

The CVE-2026-74399 issue concerns the Linux kernel evm subsystem, specifically evm_read_xattrs. The function allocates a buffer for xattrs and, when no configured xattrs are enabled, leaves temp[0] uninitialized, causing strlen(temp) to read past initialized memory. The fix terminates the buffer ...

CVE-2026-74398

CVE-2026-74398 affects the Linux kernel IPv6 address configuration (addrconf) DAD flow. The vulnerability arises when addrconf_dad_failure() transitions an interface’s state from DAD to POSTDAD and, due to a window where the interface lock is dropped, a concurrent ipv6_del_addr() can set ifp->...

CVE-2026-74397

CVE-2026-74397 affects the Linux kernel mlx5 driver (IB/mlx5). The issue arises in mlx5_ib_alloc_transport_domain() which can leak a transport domain if mlx5_ib_enable_lb() fails; a fix deallocates the TD on error, returns 0 explicitly in the no-loopback-capability success branch, and moves dev-&...

CVE-2026-74396

CVE-2026-74396 affects the Linux kernel in the RDMA/mlx5 stack. The issue occurs in the path that allocates and DMA maps an XLT buffer via mlx5r_umr_create_xlt() and releases it through mlx5r_umr_unmap_free_xlt(). If mlx5_odp_populate_xlt() encounters an error, its error path previously returned ...

CVE-2026-74394

In the Linux kernel CVE-2026-74394, RDMA/srpt is affected by an integer overflow in the immediate data length check. The vulnerability occurs because imm_buf->len is a user-controlled uint32_t received from the network, and adding it to imm_data_offset without overflow checking can allow an in...

CVE-2026-74395

CVE-2026-74395 relates to the Linux kernel MLX5 RDMA driver. The vulnerability is a NULL dereference in the devx subscribe-event unwind path within MLX5_IB_METHOD_DEVX_SUBSCRIBE_EVENT, triggered when eventfd_ctx_fdget() fails and the unwind code dereferences event_sub->ev_file before its field...

CVE-2026-74393

In the Linux kernel DRM subsystem, a memory leak was fixed in drm_syncobj_find_fence(). The root cause was that drm_syncobj_find() takes a reference to a syncobj and the function could return early without dropping that reference, leaking memory. The fix (commit 18226ba52159) also changes handlin...

CVE-2026-74392

Summary of CVE-2026-74392 (Linux kernel, device-mapper): The issue involves the dm_poll_bio() callback used by stacked dm devices. The caller only knows about the dm queue and could initiate spinning polls, passing flags unchanged to the mapped clone, which may cause blk_mq_poll() to spin on a ta...

CVE-2026-74391

In CVE-2026-74391, the Linux kernel tracing subsystem is affected by a buffer-overflow risk in synthetic-field string construction. The vulnerability arises because synthetic field helpers append strings with strcat() to fixed MAX_FILTER_STR_VAL buffers, allowing long key lists, field names, or s...

CVE-2026-74390

CVE-2026-74390 affects the Linux kernel’s RDMA/irdma path. The vulnerability stems from an out-of-bounds write in irdma_copy_user_pgaddrs, which iterates over umem DMA blocks to fill PBLEs. When irdma_setup_pbles is called with lvl==0, the loop may not exit properly if palloc->total_cnt == 0, ...
