| In the Linux kernel, the following vulnerability has been resolved: drm/imagination: Fix double call to drm_sched_entity_fini() Call sequence of double call: pvr_context_destroy pvr_context_kill_queues pvr_queue_kill drm_sched_entity_destroy drm_sched_entity_fini // here pvr_context_put kref_put(..., pvr_context_release) pvr_context_destroy_queues pvr_queue_destroy drm_sched_entity_fini // here Call to drm_sched_entity_destroy() from pvr_context_kill_queues() calls drm_sched_entity_flush() + drm_sched_entity_fini(). drm_sched_entity_flush() ensures all pending jobs are completed and drm_sched_entity_fini() ensures no further submission is allowed as per expectation from pvr_context_kill_queues(). Double call to drm_sched_entity_fini() is misuse of the API so keep call only in pvr_context_create() failure path.

| CVE-2026-68300 | 1 Linux | 1 Linux Kernel | 2026-08-13 | 7.0 High |
| In the Linux kernel, the following vulnerability has been resolved: sctp: auth: verify auth requirement when auth_chunk is NULL sctp_auth_chunk_verify() returns true unconditionally when chunk->auth_chunk is NULL, silently skipping authentication. This is incorrect when: 1. skb_clone() failed in the BH receive path, leaving auth_chunk NULL. In sctp_endpoint_bh_rcv() asoc is NULL for new connections, so the early sctp_auth_recv_cid() check cannot catch this. 2. No AUTH chunk precedes COOKIE-ECHO, so skb_clone() is never called and auth_chunk remains NULL. Fix by checking sctp_auth_recv_cid() when auth_chunk is NULL: if authentication is required, return false to drop the chunk; otherwise continue normally. | ||||
| CVE-2026-68302 | 1 Linux | 1 Linux Kernel | 2026-08-13 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: amt: re-read skb header pointers after every pull Several AMT receive and transmit paths cache a pointer into the skb head (ip_hdr(), ipv6_hdr(), eth_hdr() or the AMT message header) and then call a helper that can reallocate that head before the cached pointer is used again. pskb_may_pull(), ip_mc_may_pull(), ipv6_mc_may_pull(), iptunnel_pull_header(), ip_mc_check_igmp() and ipv6_mc_check_mld() can all free the old head and move the data, so a pointer taken before the call dangles afterwards and the later access is a use-after-free of the freed head. The affected sites are: amt_rcv() caches ip_hdr() before amt_parse_type() pulls, then reads iph->saddr. amt_dev_xmit() caches ip_hdr()/ipv6_hdr() before ip_mc_check_igmp()/ ipv6_mc_check_mld() and pskb_may_pull(), then reads the group address. amt_multicast_data_handler() caches eth_hdr() before pskb_may_pull(), then writes the L2 header. amt_membership_query_handler() caches the AMT header, the outer and inner eth_hdr() and ip_hdr() before iptunnel_pull_header() and several pulls, then reads and writes them. amt_igmpv3_report_handler() and amt_mldv2_report_handler() cache ip_hdr()/ipv6_hdr() and the current group record and read the record count from the report header inside the record loop, across the *_mc_may_pull() calls. amt_update_handler() caches ip_hdr() and the AMT membership-update header before pskb_may_pull(), iptunnel_pull_header(), ip_mc_check_igmp() and the report handler, then reads iph->daddr and amtmu->nonce / amtmu->response_mac. Fix each site by either snapshotting the scalar that is used after the pull before the first pull runs, or re-deriving the header pointer from the skb after the last pull that can move the head. Values that are stable across the pull (source and group address, the response MAC and nonce, the record count, the outer source MAC) are snapshotted; pointers that are written through or read repeatedly are re-derived. | ||||

| CVE-2026-68329 | 1 Linux | 1 Linux Kernel | 2026-08-13 | 4.7 Medium |
| In the Linux kernel, the following vulnerability has been resolved: iommu/amd: Wait for completion instead of returning early in iommu_completion_wait() need_sync is a per-IOMMU flag shared by all domains and devices behind that IOMMU. It is set whenever a command is queued with sync == true and cleared when a completion-wait (CWAIT) command is queued. However, a cleared need_sync only means that a covering CWAIT has been queued, not that all previously queued commands have actually completed in hardware. iommu_completion_wait() read need_sync locklessly and returned early when it was false. This breaks the "block until all previously queued commands have completed" contract in a multi-CPU scenario: CPU2: queue inv-B => need_sync = true CPU1: queue CWAIT(N); need_sync = false; then wait_on_sem(N) CPU2: read need_sync == false => return 0 (no wait!) CPU2 returns without waiting for any sequence number even though its inv-B may not have completed yet (CWAIT(N), queued after inv-B, has not been signaled). CPU2 then proceeds to, for example, free page-table pages while the IOMMU can still walk stale translations, opening a use-after-free window. This is a logical race in the meaning of the flag, not a memory-visibility issue, so barriers alone do not help. Fix it without losing the optimization of avoiding redundant CWAIT commands: take iommu->lock before testing need_sync, and when it is false do not return early but wait for the last allocated sequence number (cmd_sem_val). Since need_sync == false implies no sync command was queued after the last CWAIT, that CWAIT is FIFO-ordered after every not-yet-completed command, so waiting for its sequence number guarantees all prior commands (possibly queued by another CPU) have completed. The common path with pending work is unchanged and no extra hardware command is issued. | ||||
| CVE-2026-68343 | 1 Linux | 1 Linux Kernel | 2026-08-13 | 7.3 High |
| In the Linux kernel, the following vulnerability has been resolved: smb: client: validate DFS referral PathConsumed parse_dfs_referrals() validates that the response contains the fixed referral entry array and, on for-next, the per-referral string offsets. However, the response also contains a PathConsumed value that is later used for DFS path parsing. If a malformed response provides a PathConsumed value larger than the search name, later DFS parsing can advance beyond the end of the path. Validate PathConsumed against the search name length before storing it in the parsed referral. | ||||
| CVE-2026-73077 | 1 Vim | 1 Vim | 2026-08-13 | 7.3 High |
| Vim is an open source, command line text editor. Prior to 9.2.0839, the runtime/ftplugin/sh.vim, runtime/ftplugin/zsh.vim, and runtime/ftplugin/ps1.vim filetype plugins pass attacker-controlled Visual-mode selections from K through keywordprg commands without safely separating shell arguments. fnameescape() and PATH_ESC_CHARS do not neutralize shell metacharacters before ShKeywordPrg, ZshKeywordPrg, or GetHelp invokes bash, zsh, or PowerShell, allowing arbitrary operating-system commands to execute with the privileges of the user running Vim. This issue is fixed in version 9.2.0839. | ||||
| CVE-2026-73078 | 1 Vim | 1 Vim | 2026-08-13 | 8.8 High |
| Vim is an open source, command line text editor. Prior to 9.2.0840, runtime/plugin/netrwPlugin.vim loads netrw and runtime/pack/dist/opt/netrw/autoload/netrw.vim constructs Bookmarks, History, and Targets menu entries by interpolating attacker-controlled directory paths into executed :menu commands. s:NetrwBookmarkMenu(), s:NetrwTgtMenu(), g:netrw_menu_escape, EX_TRLBAR, and netrw#MakeTgt() fail to neutralize the | command separator or single quotes at five construction sites, allowing a crafted path browsed or bookmarked in GUI Vim to execute arbitrary Ex and operating-system commands.

| CVE-2026-42142 | 1 Baptistearno | 1 Typebot.io | 2026-08-13 | 7.1 High |
| TypeBot is a chatbot builder tool. Prior to version 3.17.0, the `handleGetSheets` API handler (`POST /api/sheets/getSheets`) does not validate workspace membership, allowing any authenticated user to access and decrypt another workspace's Google Sheets OAuth credentials and retrieve spreadsheet data (sheet names, IDs, column headers). Version 3.17.0 fixes the issue. | ||||
| CVE-2026-56721 | 1 Owen2345 | 1 Camaleon Cms | 2026-08-13 | 8.8 High |
| CamaleonCMS version 2.9.2 and earlier contains a privilege escalation vulnerability via insecure direct object reference (IDOR) that allows authenticated low-privileged attackers to overwrite any user's credentials by exploiting a parameter confusion flaw between the authorization filter and action body in the UsersController. Attackers can send a PATCH request to the updated_ajax endpoint setting params[:id] to their own user ID to pass the self-authorization check while simultaneously setting params[:user_id] to a victim's ID, causing the controller to load and mutate the victim's account, including overwriting administrator passwords to achieve full site takeover. | ||||
| CVE-2026-73079 | 1 Wei-shaw | 1 Sub2api | 2026-08-13 | 8.5 High |
| Sub2API is an AI API gateway platform designed to distribute and manage API quotas from AI product subscriptions. From 0.1.135, to 0.1.168, platform API keys issued to tenants are exchanged for upstream requests made with shared provider accounts (ChatGPT/Codex OAuth, OpenAI platform keys, or an operator-configured base URL) that belong to the operator, not to the caller. The `POST /responses/*subpath` wildcard routes spliced the client-supplied subpath into the upstream URL with no validation. This lets an authenticated tenant relay requests to arbitrary upstream endpoints using pooled account credentials via a path traversal. This vulnerability is fixed in 0.1.169. | ||||
| CVE-2026-48766 | 1 Baptistearno | 1 Typebot.io | 2026-08-13 | 7.6 High |
| TypeBot is a chatbot builder tool. Versions prior to 3.17.0 allow a low-privilege guest member of a workspace to exfiltrate stored OpenAI-compatible API keys by invoking the OpenAI model-listing helper with an attacker-controlled `baseUrl`. The vulnerable path decrypts the selected workspace credential, creates an OpenAI client with the secret in both `apiKey` and the explicit `api-key` header, and then sends the outbound request to the caller-supplied URL. Because the permission check accepts any readable workspace member and `listCredentials` reveals credential identifiers to guests, a guest can force the server to deliver the workspace secret to attacker infrastructure. Version 3.17.0 patches the issue. | ||||

| CVE-2026-68271 | 1 Linux | 1 Linux Kernel | 2026-08-13 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: drm/nouveau: fix reversed error cleanup order in ucopy functions nouveau_uvmm_vm_bind_ucopy() and nouveau_exec_ucopy() place their error cleanup labels in allocation order rather than reverse allocation order. On a u_memcpya() failure for in_sync.s, the goto to err_free_ops (or err_free_pushs) frees the first allocation and then falls through to err_free_ins, which calls u_free() on args->in_sync.s. Since args->in_sync.s still holds the ERR_PTR returned by the failed u_memcpya(), and ERR_PTR values are not caught by ZERO_OR_NULL_PTR(), kvfree() proceeds to dereference it, which can result in a kernel oops. A failure for out_sync.s instead jumps to err_free_ins and skips freeing the first allocation, leading to a memory leak. Fix by swapping the cleanup label order so resources are freed in the correct reverse allocation sequence. | ||||
