CVE-2026-43296

The CVE-2026-43296 case affects the Linux kernel driver octeontx2-af, where the NIX SQ manager sticky mode can stall when multiple SQs share an SMQ and transmit concurrently, and transitions between sticky and non-sticky transmissions can deadlock the PSE, with additional credit drops when clocks...

CVE-2026-43297

The CVE-2026-43297 issue affects the Linux kernel rockchip: rga driver. rga_get_frame() can return ERR_PTR(-EINVAL) for unsupported/invalid buffer types, and rga_buf_init() may dereference that pointer without checking the error, leading to a crash. The fix adds proper ERR_PTR checking in rga_buf...

CVE-2026-43328

Root cause: in the Linux kernel cpufreq governor, the error path in cpufreq_dbs_governor_init() could trigger a double free when kobject_init_and_add() fails. The kobject release path previously attempted cleanup via gov->exit(dbs_data) and kfree(dbs_data) twice. The fix keeps a direct kfree(d...

CVE-2026-46057

The connected OpenSUSE advisory for CVE-2026-46057 documents a Linux kernel Landlock issue where fork() does not preserve the Landlock security blob because hook_cred_transfer() only copies the blob when a domain exists. The fix is to unconditionally copy the Landlock credential blob to ensure su...

CVE-2026-46061

Summary: CVE-2026-46061 is a Linux kernel issue in jbd2/journal handling that can cause an ABBA deadlock when filesystem blocksize is smaller than pagesize.

CVE-2026-53113

The CVE-2026-53113 entry concerns the Linux kernel Wi‑Fi driver ath11k. The issue is a memory leak in beacon template setup: ath11k_mac_setup_bcn_tmpl_ema() and ath11k_mac_setup_bcn_tmpl_mbssid() allocate memory for beacon templates but do not free it on error, risking resource exhaustion. The do...

CVE-2026-53124

CVE-2026-53124 concerns the Linux kernel ublk subsystem. A per-IO canceled flag incorrectly remains set if a ublk server dies during device recovery before all IOs are fetched, causing cancellation of fetch commands to potentially never complete. This leaves outstanding I/O and can lead to resour...

The vulnerability is addressed...

CVE-2026-53318

The CVE-2026-53318 affects the Linux kernel wifi subsystem, specifically the mt76: mt7925 driver. A NULL pointer dereference in mt7925_tx_check_aggr() is addressed by moving the NULL check for 'sta' before it is dereferenced, which prevents a possible crash (DoS). This fix is described as resolve...

CVE-2026-63793

CVE-2026-63793 affects the Linux kernel’s NTFS handling. The issue arises from unsafe concurrent access to vol->volume_label during FS_IOC_SETFSLABEL and FS_IOC_GETTSLABEL, which could lead to a use-after-free. The patch inserts a mutex to guard the volume_label and snapshots the label before ...

CVE-2026-64049

CVE-2026-64049 is a NULL pointer dereference in the Linux kernel's DRM MSM Adreno GPU driver. On Adreno a2xx–a4xx GPUs, the driver does not fetch UBWC (Universal Bandwidth Compression) parameters because those generations do not support them, yet userspace can still query UBWC-related parameters ...

CVE-2026-64126

The CVE-2026-64126 entry concerns the Linux kernel Bluetooth MGMT path for Add Extended Advertising Data. A vulnerability exists where MGMT_OP_ADD_EXT_ADV_DATA is a variable-length command and the fixed-header size plus advertised data lengths are not validated against cp->data, allowing an ou...

CVE-2026-64146

The Linux kernel's EROFS filesystem has a memory leak in erofs_init_inode_xattrs(): after commit bb88e8da0025 converted xattr operations to on-stack erofs_buf instances, certain error paths after erofs_read_metabuf() exit through out_unlock without dropping the metabuf, leaking folio references. ...

CVE-2026-64216

CVE-2026-64216: Linux kernel netfs UAF fix. The issue occurs in netfs_unlock_abandoned_read_pages() (and netfs_unlock_read_folio()) where the code dereferenced an index after NETFS_RREQ_IN_PROGRESS was cleared, risking access to the folio protected by no_unlock_folio. The fix stores the folio poi...

CVE-2026-64243

CVE-2026-64243 (Linux kernel, ASoC codecs: simple-mux) A fix was applied to correct the bounds check in simple_mux_control_put for enum controls. Previously the code rejected values greater than e->items, but enum controls are zero-based, making 0 and 1 valid for a two-entry mux and 2 should b...
