BlueALSA (bluez-alsa/bluealsad) contains a division-by-zero vulnerability in the LC3plus sink decoder (a2dp-lc3plus.c, a2dp_lc3plus_dec_thread) that allows a Bluetooth-adjacent attacker to crash the daemon by sending a crafted RTP media header with an attacker-controlled frame count field set to zero. Attackers can establish an A2DP source connection with an LC3plus session negotiated against a victim running bluealsad as an A2DP sink and transmit a non-fragmented LC3plus media header with a zero frame count to trigger a SIGFPE in the decoding thread, causing a denial of service on builds compiled with LC3plus support enabled.

Sep 30, 2026MISP renders the source field of a Galaxy Cluster as a clickable hyperlink whenever the stored value passes PHP's FILTER_VALIDATE_URL validation.CVE-2026-103388 · Other software · MISP · reported by 5a6e4751-2f3f-4070-9419-94fb35b644e8Medium 6.2
MISP renders the source field of a Galaxy Cluster as a clickable hyperlink whenever the stored value passes PHP's FILTER_VALIDATE_URL validation. Because FILTER_VALIDATE_URL accepts the javascript: URI scheme, a user with galaxy editor privileges on the local instance or on a synced instance could store a javascript: URL as the cluster source. When another user views the affected Galaxy Cluster and clicks the rendered link, the embedded script executes in the victim's browser context, enabling session hijacking, data exfiltration, or actions performed on behalf of the victim. Preconditions: - Attacker must hold galaxy editor privileges (local or via sync). - Victim must view the affected cluster and click the malicious link. Impact: - Stored cross-site scripting (XSS) in the victim's browser. - Potential session theft, credential harvesting, or unauthorized actions within the MISP application. Affected: <2.5.48.

In Baicells Nova 430H, an unauthenticated device within radio range can send a malformed uplink message during connection setup that contains an invalid NAS payload. Because the eNodeB does not properly validate this payload, it forwards the message to the core network, which can trigger a shutdown of the signaling association for the cell. This results in a temporary service disruption until the eNodeB and core network re-establish connectivity.

mark3labs mcp-filesystem-server v0.11.1 is vulnerable to Directory Traversal due to an improper link resolution in validatePath (filesystemserver/handler/helper.go).

The CoAP link-format helper match_path_uri() in subsys/net/lib/coap/coap_link_format.c compares a registered resource path against the URI carried in a Uri-Query href= option. That URI is not NUL terminated, but the inner character loop advanced its index k once per path character without ever testing it against the option length len. When a registered path segment is longer than the supplied URI and the URI is a prefix of it, the loop reads uri[len] and beyond, past the end of the option value. The path is reached from coap_well_known_core_get_len() and coap_well_known_core_get() via match_queries_resource(), i.e. by any unauthenticated GET /.well-known/core?href=/<prefix> request to a device that serves /.well-known/core (for the CoAP server subsystem, CONFIG_COAP_SERVER_WELL_KNOWN_CORE, default y) and has at least one resource that declares struct coap_core_metadata attributes. The over-read does not reach the receive buffer. The well-known-core builders parse the query into a stack-local struct coap_option, whose value is a fixed array (value[12], or CONFIG_COAP_EXTENDED_OPTIONS_LEN_VALUE bytes) that the option bytes are copied into, so uri points into that copy.

Sep 26, 2026Froxlor through 2.3.10 is vulnerable to arbitrary file deletion via symlink following in the FTP data deletion cron task.CVE-2026-100715 · Other software · froxlor · reported by VulnCheckHigh 8.5
Froxlor through 2.3.10 is vulnerable to arbitrary file deletion via symlink following in the FTP data deletion cron task. Cron task 8 (deleteFtpData), queued when an FTP account is deleted, calls FileDir::makeCorrectDir() without the $fixed_homedir argument, so the symlink component walk is skipped, and then executes 'rm -rf' as root on the resulting path with string-level guards only. Because makeCorrectDir() appends a trailing slash, GNU rm dereferences a symlink used either as an intermediate path component or as the final component. An authenticated customer who can write to the FTP home directory can plant a symlink between task insertion and cron execution, causing the root cron job to recursively delete arbitrary directory trees, resulting in cross-tenant data destruction and host denial of service. This issue is fixed in Froxlor 2.3.12.

Improper Link Resolution Before File Access in the drag source staging path of the drag and drop protocol in kitty from 0.47.0 before 0.49.0 allows a program writing to the terminal to create files and directories at paths outside the staging directory, because subdir_data_for_drag() in kitty/dnd.c resolves a descendant of the staged item tree by constructing a path string and opening it with safe_open(path, O_DIRECTORY | O_RDONLY, 0) rather than by walking the tree one component at a time, so a client that declares two entries with the same name, the first a symlink whose target is an arbitrary absolute path and the second a directory, causes mkdirat() to fail with EEXIST, which the code ignores, and causes the subsequent path resolution to follow the symlink and return a directory descriptor outside the staging directory, which is then passed as the dirfd argument to add_payload() and used for every further create operation on that item and its descendants. Entry names are sanitised against path separators and dot components, but symlink targets are not validated.

In the Linux kernel, the following vulnerability has been resolved: netfilter: nf_nat_sip: rewind offset when NAT shrinks the packet sashiko says: If map_addr() changes the packet length, such as when the public NAT IP string is shorter or longer than the internal IP, coff will still point to the offset relative to the pre-mangled packet. If the packet shrinks, coff could overshoot the correct position, potentially causing the next ct_sip_parse_header_uri() call to silently skip bytes and miss subsequent Contact headers. Could this lead to a failure to NAT those subsequent headers and leak internal network details?

In the Linux kernel, the following vulnerability has been resolved: bpf: Don't resurrect a scalar id dropped by collect_linked_regs() check_cond_jmp_op() copies the compared registers into env->{false,true}_reg{1,2} before collect_linked_regs() runs and copies those snapshots back into both branch states afterwards. collect_linked_regs() records at most LINKED_REGS_MAX members of a linked registers group in the jump history and calls clear_scalar_id() for every member that does not fit. The compared register is not exempt from that. As a consequence, sync_linked_regs() might adjust ranges for more registers than bpf_bt_sync_linked_regs() can propagate precision to. Collect the linked registers before the snapshots are taken instead. This might lead to some unnecessary clear_scalar_id's, but from previous testing situations with many linked registers are extremely rare.

In the Linux kernel, the following vulnerability has been resolved: net: reject oversized tx_queue_len at netlink parse time rtnl_create_link() assigns IFLA_TXQLEN directly to dev->tx_queue_len without going through netif_change_tx_queue_len(), so a device created with "ip link add ... txqueuelen 500000" bypasses the S16_MAX cap and still triggers the oversized ring allocations in pfifo_fast, tun and tap. The veth peer nest (rtnl_nla_parse_ifinfomsg()) and the RTM_NEWLINK-on-existing-device path reach the same sinks. Enforce the cap in ifla_policy instead: IFLA_TXQLEN becomes NLA_POLICY_FULL_RANGE(NLA_U32, &txqlen_range) with txqlen_range = { .min = 0, .max = S16_MAX }. All netlink consumers parse against this policy - rtnl_setlink(), rtnl_newlink() (create and change), and the veth peer nest - so every netlink path is capped at parse time and rejects the attribute with -ERANGE plus a proper "integer out of range" extack message before any device state is modified (the RTM_SETLINK half-application wart is gone with it). Document the bound in the rt-link.yaml netlink spec. Conditions to recreate the bug: - CONFIG_NET_SCHED=y, CONFIG_VETH=y, CONFIG_USER_NS=y, CONFIG_NET_NS=y. -

In the Linux kernel, the following vulnerability has been resolved: net: macb: fix NULL pointer dereference on unbind with fixed-link When the device tree describes a fixed-link and has no "mdio" child node, macb_mii_init() returns early without allocating the MDIO bus, leaving bp->mii_bus as NULL. Two cleanup paths then dereference this NULL bus: 1. On driver unbind, macb_remove() unconditionally calls mdiobus_unregister(bp->mii_bus), which oopses: Unable to handle kernel NULL pointer dereference at virtual address 00000000000004a8 pc : mdiobus_unregister+0x14/0xa4 lr : macb_remove+0x38/0xa4 Call trace: mdiobus_unregister+0x14/0xa4 (P) macb_remove+0x38/0xa4 platform_remove+0x20/0x30 device_release_driver_internal+0x1c8/0x224 unbind_store+0xb4/0xbc 2. On the probe error path in macb_probe(), reached when macb_mii_init() has succeeded but a subsequent step fails, the err_out_unregister_mdio label runs the same unconditional cleanup. mdiobus_unregister() and mdiobus_free() do not guard against a NULL bus, so guard the calls in both macb_remove() and the probe error path.

In the Linux kernel, the following vulnerability has been resolved: net: macb: destroy the phylink instance on the probe error path macb_mii_init() creates a phylink instance on both of its success paths, but the probe unwind frees the netdev without destroying it, so a failing macb_alloc_tieoff() or register_netdev() leaks the instance. Destroy it at err_out_unregister_mdio, which is only reachable once macb_mii_init() has succeeded, so bp->phylink is valid there.

In the Linux kernel, the following vulnerability has been resolved: configfs: pin the symlink target's dirent instead of chasing ->ci_dentry create_link() reads the target's configfs_dirent from item->ci_dentry->d_fsdata, relying on the item reference taken by get_target(). That reference pins the item, not its dentry: the dentry is pinned by DCACHE_PERSISTENT, which configfs_remove_dir() releases via simple_rmdir() while the item is still alive. A symlink racing with rmdir of its target can therefore find ->ci_dentry freed and its dirent released, triggering WARN_ON(!atomic_read(&sd->s_count)) in configfs_get(). Take the dirent in get_target() as well, under ->d_lock and atomically with the item reference, and pass it down to create_link(). A hashed dentry has not been killed yet, so its ->d_fsdata reference keeps the dirent alive there.

In the Linux kernel, the following vulnerability has been resolved: genetlink: pin family module during policy dump The generic netlink controller's policy dump keeps pointers to the target family's operation and policy tables in its callback state. A dump may be split across multiple skbs and remain pending after the initial request. Netlink pins the module which owns the dump callback, but in this case that is the controller's owner rather than the target family's owner. The target family can consequently be unregistered and its module unloaded while a policy dump is pending. Advancing the dump then dereferences policy memory from the unloaded module. Take a reference to the target family's module when the dump starts. Drop it from the error and done paths. This matches the lifetime for which the dump context retains the family and policy pointers.

In the Linux kernel, the following vulnerability has been resolved: xfs: fix exchange-range reflink flag clearing issue with INO1_WRITTEN When exchanging two full-file ranges, xmi_can_exchange_reflink_flags() can move the reflink inode flag from the file that currently has it to the other file, as long as exactly one side is marked. This assumes that the file contents, and therefore all shared extents, are exchanged. That assumption is not true when XFS_EXCHMAPS_INO1_WRITTEN is set. xfs_exchmaps_can_skip_mapping() can skip hole and unwritten mappings from file1, so an exchange can complete without moving every mapping that the earlier flag-swap decision accounted for. In that case the post-operation cleanup can clear the reflink flag from an inode that still owns shared written extents. Later writes then take the non-reflink write path and may update blocks that should still have been protected by CoW, which shows up as data corruption between reflink-related files. Fix this by disabling the reflink flag exchange whenever XFS_EXCHMAPS_INO1_WRITTEN is requested. The contents exchange can still proceed; the conservative outcome is that both inodes keep the reflink flag. The
