| CVE-2026-68407 | 1 Linux | 1 Linux Kernel | 2026-08-11 | 5.3 Medium |
| In the Linux kernel, the following vulnerability has been resolved: wifi: nl80211: free RNR data on MBSSID mismatch nl80211_parse_beacon() rejects EMA RNR data when there are fewer RNR entries than MBSSID entries. The rejected RNR allocation has not been attached to the beacon data yet, so free it before returning the error. | ||||

| When using the "configparser" module to write configuration files containing multi-line text values with carriage return characters (\r) the resulting file could be injected with unexpected keys and values if the attacker controls the written value. | ||||
| CVE-2026-11940 | 1 Python | 1 Cpython | 2026-08-11 | N/A |
| tarfile.extractall() with the 'data' or 'tar' filter could be bypassed by a crafted archive where a hardlink references a symlink stored at a deeper name than the hardlink itself. The extraction fallback validated the symlink at it's archived location but recreated it at the hardlink's shallower path, letting a relative target the filter judged contained escape the destination directory. This allowed a malicious tar archive to create a symlink pointing outside the destination, enabling out-of-destination file reads or writes. This was an incomplete fix of CVE-2025-4330. | ||||

| To allow builds of Python to be run from an in-tree layout (rather than an installed file layout), the VPATH variable is defined at build time and used to locate certain landmarks - specifically, Modules/setup.local. When this landmark is found relative to VPATH relative to the executable, Python assumes it is running in a source tree and generates a different default sys.path. This code remains in release builds, so that release-ready builds can be built in-tree. On Windows, since builds are written to 'PCbuild/', the value of VPATH is set to '..\..', which results in a landmark of '..\..\Modules\setup.local'. This path is outside the install directory of Python, and may have different permissions, potentially allowing a low-privilege user to create the landmark and an alternative `Lib` folder that will be discovered by an otherwise restricted install. Such a setup occurs with the legacy default install location for all users (in the now superseded EXE installer), due to how Windows allows all users to create folders in the root directory of their OS drive. Our recommended mitigation on Windows is to migrate away from the legacy installer and use the new [Python install manager](https://www.python.org/downloads/latest/pymanager/) to install for the current user. Installs where the directory two levels above the Python installation directory have equivalent permissions are unaffected (in general, a per-user install cannot be modified at all by other users, removing any escalation of privilege risk, and could be directly modified by a privileged user, making the potential tampering irrelevant). Alternative mitigations might include preemptively creating and restricting access to a `Modules` directory. Be aware that only 3.13 and 3.14 will receive updated legacy installers - earlier fixes are only provided as sources. Platforms other than Windows allow VPATH to be overridden, but as they don't usually use a separated directory in the build for binaries, are unlikely to have a landmark reference outside of the install directory. The landmark detection involving VPATH is a fallback for when a more specific landmark - .\pybuilddir.txt - is absent, and was included for compatibility. Future releases of Python will no longer include the fallback, and so builds will need to generate or preserve the pybuilddir.txt file in order to work in-tree. This landmark file has been generated on Windows since 3.11, and on other platforms for longer. | ||||

| CVE-2026-6879 | 2 Python, Redhat | 2 Cpython, Hummingbird | 2026-08-11 | 2.2 Low |
| `Element.findall()` and fully-consumed `Element.iterfind()` exhibit `O(n^2)` time complexity when using XPath index predicates (e.g. `[1]`, `[last()]`, `[last()-N]`) on XML documents with many same-tag siblings. `Element.find()` is only affected when the first match is near the end of the sibling list, such as with `[last()]` or `[last()-N]`; `.//item[1]` short-circuits after the first match. | ||||
| CVE-2026-9669 | 1 Python | 1 Cpython | 2026-08-11 | 5.9 Medium |
| bz2.BZ2Decompressor objects could be reused after a decompression error. If an application caught the resulting OSError and retried with the same decompressor, crafted input could cause the decompressor to resume from an invalid internal state and perform out-of-bounds writes to a stack buffer. This could crash the process when processing untrusted data. | ||||
| CVE-2026-68384 | 1 Linux | 1 Linux Kernel | 2026-08-11 | 6.0 Medium |
| In the Linux kernel, the following vulnerability has been resolved: drm/xe/vf: Fix VF CCS attach/detach race with in-flight BO moves xe_bo_move() attaches VF CCS read/write batch buffers (BBs) to a BO after it transitions NULL/SYSTEM -> TT, and detaches them after it transitions TT -> SYSTEM. Both operations were done synchronously on the CPU immediately after building the move's copy/clear fence, without waiting for that fence to signal. This creates two races with VF migration: - Attach happens too late relative to the copy job it is meant to protect. If the copy job is submitted before the CCS BBs are attached, a VF migration event that pauses execution mid-copy can observe partially copied CCS metadata without the attach state needed to correctly save/restore it. - Detach happens too early relative to the copy job that moves data out of TT. The CCS BBs are torn down right after the copy fence is obtained, while the actual blit may still be in flight. A VF migration event that pauses execution mid-copy can then race the save/restore path against the still-running blit, and the CCS BBs it would need to make sense of the paused state have already been removed. Fix both races: - Move the attach call to before the copy/clear job is submitted, so the CCS BBs are already registered by the time the copy runs. On attach failure, unwind and bail out of the move. xe_migrate_ccs_rw_copy() now takes the destination resource explicitly, since bo->ttm.resource is not updated to the new resource until after the move commits. - Detach only after explicitly waiting for the copy fence to signal, instead of tearing down the CCS BBs immediately after obtaining it. While here, also fix xe_sriov_vf_ccs_attach_bo() to properly unwind and propagate errors: the per-context loop previously never broke out on error, silently discarding earlier failures. Unwind by clearing each attached context directly via xe_migrate_ccs_rw_copy_clear() instead of reusing xe_sriov_vf_ccs_detach_bo(), which requires both contexts to be attached before it will clean up either one.

| CVE-2026-68385 | 1 Linux | 1 Linux Kernel | 2026-08-11 | 4.4 Medium |
| In the Linux kernel, the following vulnerability has been resolved: s390/checksum: Fix csum_partial() without vector facility Currently csum_partial() calls csum_copy() with copy=false and dst=NULL. On machines without the vector facility, csum_copy() falls back to cksm(dst, ...), causing the checksum to be calculated from address zero instead of the source buffer. The VX implementation already checksums data loaded from src. Make the fallback do the same by passing src to cksm(). | ||||
| CVE-2026-68396 | 1 Linux | 1 Linux Kernel | 2026-08-11 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: scsi: core: wake eh reliably when using scsi_schedule_eh Drivers which use the scsi_schedule_eh function to run the error handler currently risk the error handler thread never waking once all commands are timed out or inactive. There is no enforced memory order between setting the host into error recovery state and counting busy commands. This can result in a race with scsi_dec_host_busy where neither CPU sees both conditions of all commands inactive and the host error state to request waking the error handler. To fix this, run the scsi_schedule_eh's scsi_eh_wakeup from a new work item which will use rcu to ensure scsi_schedule_eh's call to scsi_host_busy will occur after the error state is globally visible and will be seen by any current scsi_dec_host_busy callers. | ||||

| CVE-2026-68307 | 1 Linux | 1 Linux Kernel | 2026-08-11 | 4.8 Medium |
| In the Linux kernel, the following vulnerability has been resolved: wifi: mt76: mt7925: fix crash in reset link replay During reset recovery, mt7925_vif_connect_iter() replays firmware state for links tracked in mvif->valid_links. After MLO link changes or MCU timeout recovery, the driver bitmap can temporarily contain a link whose mac80211 bss_conf has already gone away. This can pass a NULL bss_conf to mt76_connac_mcu_uni_add_dev(), matching the crash where x1, the second argument, is NULL: pc : mt76_connac_mcu_uni_add_dev+0x8c/0x1f8 [mt76_connac_lib] lr : mt7925_vif_connect_iter+0x9c/0x168 [mt7925_common] x2 : ffffff80a77f6018 x1 : 0000000000000000 x0 : ffffff8099402080 Call trace: mt76_connac_mcu_uni_add_dev+0x8c/0x1f8 [mt76_connac_lib] mt7925_vif_connect_iter+0x9c/0x168 [mt7925_common] mt7925_mac_reset_work+0x264/0x2f8 [mt7925_common] Skip missing bss_conf entries before replaying the link. Non-MLO AP/STA reset replay is unchanged because the helper still returns &vif->bss_conf for the legacy link. | ||||
| CVE-2026-68366 | 1 Linux | 1 Linux Kernel | 2026-08-11 | 6.1 Medium |
| In the Linux kernel, the following vulnerability has been resolved: usb: gadget: uvc: clamp SEND_RESPONSE length to the response buffer uvc_send_response() builds the UVC control response from a user-supplied struct uvc_request_data: req->length = min_t(unsigned int, uvc->event_length, data->length); ... memcpy(req->buf, data->data, req->length); req->length is clamped to uvc->event_length, which is taken from the host control request wLength (up to UVC_MAX_REQUEST_SIZE, 64), and to data->length, which comes from the UVCIOC_SEND_RESPONSE ioctl and is only checked for being negative. The source buffer data->data is only 60 bytes, so a response with uvc->event_length and data->length both greater than 60 makes memcpy() read past the end of data->data. Clamp req->length to sizeof(data->data) as well. | ||||
| CVE-2026-66797 | 2026-08-11 | 8.5 High | ||
| A flaw was found in the cluster-backup-operator. An attacker with write access to the backup storage location or the ability to create a Velero Backup object can inject malicious Role-Based Access Control (RBAC) resources into a backup. When this tampered backup is restored, the operator processes the malicious content, leading to a privilege escalation from backup-namespace-admin to hub cluster-admin. This allows the attacker to gain administrative control over the entire cluster. | ||||
| CVE-2026-66798 | 2026-08-11 | 8.8 High | ||
| A flaw was found in cluster-backup-operator. A namespace administrator in open-cluster-management-backup can create a Restore Custom Resource (CR) with malicious hooks. These hooks allow the execution of arbitrary commands within any matching restored pod, leading to the exfiltration of ServiceAccount tokens. This bypasses normal access controls, granting the attacker unauthorized execution access to pods and their associated Service Accounts. | ||||
| CVE-2026-66800 | 2026-08-11 | 7.1 High | ||
| A flaw was found in cluster-backup-operator. A namespace administrator with privileges in the open-cluster-management-backup namespace can exploit a feature in the Restore Custom Resource (CR). By setting the cleanupBeforeRestore field to CleanupAll, an attacker can trigger an unguarded, cluster-wide deletion of all Red Hat Advanced Cluster Management (ACM) and Hive-labelled Secrets and ConfigMaps. This leads to a denial of service across the entire hub cluster by removing critical resources. | ||||
| CVE-2026-68331 | 1 Linux | 1 Linux Kernel | 2026-08-10 | 5.9 Medium |
| In the Linux kernel, the following vulnerability has been resolved: dpaa2-eth: put MAC endpoint device on disconnect fsl_mc_get_endpoint() returns the MAC endpoint device with a reference taken through device_find_child(). The Ethernet connect path stores that device in mac->mc_dev and keeps it for the lifetime of the connected MAC object. However, the disconnect path only disconnects and closes the MAC before freeing the dpaa2_mac object. It does not drop the endpoint device reference stored in mac->mc_dev, so every successful connect leaks that device reference when the MAC is later disconnected. Drop the endpoint device reference after closing the MAC and before freeing the dpaa2_mac object. | ||||
