| CVE-2026-72306 | 1 Linux | 1 Linux Kernel | 2026-11-06 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: vduse: Fix race in vduse_dev_msg_sync and vduse_dev_read_iter There is one race case in vduse_dev_msg_sync and vduse_dev_read_iter: vduse_dev_read_iter(): lock(msg_lock); dequeue_msg(send_list); unlock(msg_lock); vduse_dev_msg_sync(): wait_timeout() finish lock(msg_lock); check msg->complete is false list_del(msg); <- double list_del() crash! To fix this case, we shall ensure vduse_msg is on send_list or recv_list outside the msg_lock critical section. | ||||

| In the Linux kernel, the following vulnerability has been resolved: VDUSE: avoid leaking information to userspace The bounceing is not necessarily page aligned, so current VDUSE can leak kernel information through mapping bounce pages to userspace. Allocate bounce pages with __GFP_ZERO to avoid leaking information to userspace. | ||||
| CVE-2026-72290 | 1 Linux | 1 Linux Kernel | 2026-11-06 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: KVM: s390: pci: Fix GISC refcount leak on AIF enable failure kvm_s390_gisc_register() registers the guest ISC before pinning the guest interrupt forwarding pages and allocating the AISB bit. If any of the later setup steps fails, the function unwinds the pinned pages and other local state, but does not unregister the GISC reference. Add the missing kvm_s390_gisc_unregister() to the error unwind path. | ||||
| CVE-2026-72276 | 1 Linux | 1 Linux Kernel | 2026-11-06 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: fbdev: metronomefb: fix potential memory leak in metronomefb_probe() The memory allocated for pagerefs in fb_deferred_io_init() is not freed on the error path. Fix it by calling fb_deferred_io_cleanup(). | ||||
| CVE-2026-72275 | 1 Linux | 1 Linux Kernel | 2026-11-06 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: fbdev: broadsheetfb: fix potential memory leak in broadsheetfb_probe() The memory allocated for pagerefs in fb_deferred_io_init() is not freed on the error path. Fix it by calling fb_deferred_io_cleanup(). | ||||
| CVE-2026-72274 | 1 Linux | 1 Linux Kernel | 2026-11-06 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: fbdev: hecubafb: fix potential memory leak in hecubafb_probe() The memory allocated for pagerefs in fb_deferred_io_init() is not freed on the error path. Fix it by calling fb_deferred_io_cleanup(). | ||||
| CVE-2026-72272 | 1 Linux | 1 Linux Kernel | 2026-11-06 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: fbdev: radeon: fix potential memory leak in radeonfb_pci_register() The function radeonfb_pci_register() allocates memory for modelist (by calling radeon_check_modes() which calls fb_add_videomode()). The memory is appended to info->modelist, but is not freed in subsequent error paths. Fix this by calling fb_destroy_modelist(). | ||||
| CVE-2026-72265 | 1 Linux | 1 Linux Kernel | 2026-11-06 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: fbdev: nvidia: fix potential memory leak in nvidiafb_probe() In nvidiafb_probe(), the memory allocated for modelist in nvidia_set_fbinfo() is not freed in the subsequent error paths. Fix that by calling fb_destroy_modelist(). | ||||
| CVE-2026-72256 | 1 Linux | 1 Linux Kernel | 2026-11-06 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: netfilter: xt_cluster: reject template conntracks in hash match xt_cluster_mt() treats any non-NULL nf_ct_get() result as a fully initialized conntrack and passes it to xt_cluster_hash(). This causes a state confusion bug when the raw table CT target attaches a template conntrack to skb->_nfct before normal conntrack processing. Templates carry IPS_TEMPLATE status but do not have a valid tuple for hashing yet, so xt_cluster_hash() can hit its WARN_ON() path on the zeroed l3num field. Reject template conntracks before hashing them. This matches existing netfilter handling for template objects and avoids hashing incomplete conntrack state. | ||||
| CVE-2026-72245 | 1 Linux | 1 Linux Kernel | 2026-11-06 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: gpu: host1x: Fix device reference leak in host1x_device_parse_dt() error path After device_initialize(), the embedded struct device in struct host1x_device should be released through the device core with put_device(). In host1x_device_add(), if host1x_device_parse_dt() fails, the current error path frees the object directly with kfree(device). That bypasses the normal device lifetime handling and leaks the reference held on the embedded struct device. The issue was identified by a static analysis tool I developed and confirmed by manual review. Fix this by using put_device() in the host1x_device_parse_dt() failure path. | ||||
| CVE-2026-72241 | 1 Linux | 1 Linux Kernel | 2026-11-06 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: leds: uleds: Fix potential buffer overread The name string supplied by userspace is not guaranteed to be null-terminated, so using strchr() on it might result in a buffer overread. The same thing will happen when said string is used by the LED class device. Fix this by using strnchr() instead and explicitly check that the name string is properly null-terminated. | ||||
| CVE-2026-72240 | 1 Linux | 1 Linux Kernel | 2026-11-06 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: mfd: sm501: Fix reference leak on failed device registration When platform_device_register() fails in sm501_register_device(), the embedded struct device in pdev has already been initialized by device_initialize(), but the failure path only reports the error and returns without dropping the device reference for the current platform device: sm501_register_device() -> platform_device_register(pdev) -> device_initialize(&pdev->dev) -> setup_pdev_dma_masks(pdev) -> platform_device_add(pdev) This leads to a reference leak when platform_device_register() fails. Fix this by calling platform_device_put() before returning the error. The issue was identified by a static analysis tool I developed and confirmed by manual review. | ||||
| CVE-2026-72230 | 1 Linux | 1 Linux Kernel | 2026-11-06 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: batman-adv: frag: free unfragmentable packet The caller of batadv_frag_send_packet() assume that the skb provided to the function are always consumed. But the pre-check for an empty payload or the zero fragment size returned an error without any further actions. A failed pre-check must use the same error handling code as the rest of the function. | ||||
| CVE-2026-72229 | 1 Linux | 1 Linux Kernel | 2026-11-06 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: batman-adv: clean untagged VLAN on netdev registration failure When an mesh interface is registered, it creates an untagged struct batadv_meshif_vlan on top of it via the NETDEV_REGISTER notifier. But in this process, another receiver of this notification can veto the registration. The netdev registration will be aborted because of this veto. The register_netdevice() call will try to clean up the net_device using unregister_netdevice_queue() - which only uses the .priv_destructor to free private resources. In this situation, .dellink will not be called. The cleanup of the untagged batadv_meshif_vlan must thefore be done in the destructor to avoid a leak of this object. | ||||
| CVE-2026-72228 | 1 Linux | 1 Linux Kernel | 2026-11-06 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: batman-adv: frag: fix primary_if leak on failed linearization If the skb has a frag_list, it must be linearized before it can be split using skb_split(). But when this step failed, it must not only free the skb but also take care of the reference to the already found primary_if. | ||||
| CVE-2026-72224 | 1 Linux | 1 Linux Kernel | 2026-11-06 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: nvdimm/btt: Free arenas on btt_init() error paths The arenas allocated by discover_arenas() or create_arenas() are not freed on some error paths in btt_init(). This leaks memory when BTT initialization fails. Call free_arenas() from the affected error paths to release the allocations. [ as: commit message and log edits ] | ||||
| CVE-2026-72223 | 1 Linux | 1 Linux Kernel | 2026-11-06 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: nvdimm/btt: Free arena sub-allocations on discover_arenas() error path Memory allocated by btt_freelist_init(), btt_rtt_init(), and btt_maplocks_init() is not freed on some discover_arenas() error paths. This leaks memory when arena discovery fails. Add the missing kfree() calls to release the allocations before returning an error. [ as: commit message and log edits ] | ||||
| CVE-2026-72219 | 1 Linux | 1 Linux Kernel | 2026-11-06 | 7.0 High |
| In the Linux kernel, the following vulnerability has been resolved: lockd: Plug nlm_file leak when nlm_do_fopen() fails A client can repeatedly drive nlm_do_fopen() failures by presenting file handles that the underlying export rejects. After kzalloc_obj() succeeds in nlm_lookup_file(), the freshly allocated nlm_file is not yet inserted into nlm_files[]. The nlm_do_fopen() failure path jumps to out_unlock, which releases nlm_file_mutex and returns without freeing the allocation, so each failure leaks one nlm_file. Route the failure through out_free so kfree() runs before the function returns. | ||||
| CVE-2026-72218 | 1 Linux | 1 Linux Kernel | 2026-11-06 | 7.0 High |
| In the Linux kernel, the following vulnerability has been resolved: lockd: Plug nlm_file refcount leak on cached nlm_do_fopen() failure The cached-file path in nlm_lookup_file() reaches the found: label unconditionally, even when nlm_do_fopen() fails. At that label *result and file->f_count are updated before the error is returned. The wrappers nlm3svc_lookup_file() and nlm4svc_lookup_file() then bail out of their switch without copying *result back to their caller, so the proc handler's local nlm_file pointer remains NULL and the cleanup path skips nlm_release_file(). The f_count increment is never released, and nlm_traverse_files() can no longer reap the file because its refcount never returns to zero between requests. Short-circuit the cached path so neither *result nor f_count is touched when nlm_do_fopen() fails on a hashed nlm_file. | ||||
| CVE-2026-72193 | 1 Linux | 1 Linux Kernel | 2026-11-06 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: ntfs3: cap RESTART_TABLE free-chain walker at rt->used A crafted NTFS3 disk image triggers an in-kernel infinite loop at mount time, hanging the mounting thread and firing the soft-lockup watchdog within ~22s on multi-CPU hosts (panic with kernel.softlockup_panic=1). The bug is reachable from desktop USB auto-mount on distributions where udisks2 routes the NTFS signature to the in-tree ntfs3 driver (Arch family and an increasing fraction of Fedora / openSUSE / RHEL deployments); CAP_SYS_ADMIN-class manual mount elsewhere. check_rstbl()'s second walker iterates the free-entry singly-linked list headed by rt->first_free with no upper bound on iteration count: for (off = ff; off;) { if (off == RESTART_ENTRY_ALLOCATED) return false; off = le32_to_cpu(*(__le32 *)Add2Ptr(rt, off)); if (off > ts - sizeof(__le32)) return false; } The existing guards cover three exits: end-of-list (off == 0), the in-use marker (off == RESTART_ENTRY_ALLOCATED), and out-of-bounds (off > ts - sizeof(__le32)). None of the three prevents an in-bounds cycle. A crafted on-disk RESTART_TABLE whose free chain contains a self-loop or A->B->A cycle whose offsets satisfy: - in range [sizeof(struct RESTART_TABLE), ts - sizeof(__le32)] - (off - sizeof(struct RESTART_TABLE)) % rsize == 0 passes all existing guards and spins the mount-time thread forever. Reproduced in UML by hand-forging a 2 MB NTFS3 image whose journal RESTART_TABLE first_free = 0x18 and whose entry at offset 0x18 stores 0x18 as its next pointer; mount of the forged image with the in-tree ntfs3 driver never returns. Bound the walker by rt->used. Each entry on a legitimate free chain is unique, and the total slot count is ne = le16_to_cpu (rt->used). A traversal that visits more than ne slots is by construction malformed; reject it as a corrupt RESTART_TABLE. After this patch, mount of the forged image returns with -EINVAL and a log_replay failure message, and mkntfs-produced legitimate images mount cleanly (verified in the same UML harness). | ||||
