| CVE-2026-80914 | 1 Linux | 1 Linux Kernel | 2026-09-14 | 8.8 High |
| In the Linux kernel, the following vulnerability has been resolved: Bluetooth: ISO: fix use-after-free of listener socket in iso_conn_ready iso_conn_ready() looks up the BIS listener socket with iso_get_sock(), which takes a reference, and then, without re-checking its state, creates a child socket from it: parent = iso_get_sock(hdev, ...); if (!parent) return; lock_sock(parent); sk = iso_sock_alloc(sock_net(parent), NULL, BTPROTO_ISO, ...); ... iso_chan_add(conn, sk, parent); ... release_sock(parent); sock_put(parent); If the listener socket is closed concurrently, between iso_get_sock() and lock_sock(), the reference taken by iso_get_sock() may be the last one: the close path drops the link-list reference, and once iso_conn_ready() drops its own reference at the end of the function the socket is freed. The child socket, however, is already linked to the freed parent, and a later disconnect of the child runs iso_chan_del() -> bt_accept_unlink(), which dereferences the dangling parent pointer into the freed accept queue (a use-after-free). The same dangling pointer is also dereferenced through parent->***() in iso_chan_del(). Fix it the same way the connected (non-BIS) path was fixed in commit 0d255e63fcf3 ("Bluetooth: ISO: hold sk properly in iso_conn_ready"): after taking the socket lock, re-check that the parent is still a listening, alive socket, and bail out otherwise. | ||||
| CVE-2026-53098 | 1 Linux | 1 Linux Kernel | 2026-09-14 | 7.8 High |
| In the Linux kernel, the following vulnerability has been resolved: wifi: mt76: mt7915: fix use-after-free bugs in mt7915_mac_dump_work() When the mt7915 pci chip is detaching, the mt7915_crash_data is released in mt7915_coredump_unregister(). However, the work item dump_work may still be running or pending, leading to UAF bugs when the already freed crash_data is dereferenced again in mt7915_mac_dump_work(). The race condition can occur as follows: CPU 0 (removal path) | CPU 1 (workqueue) mt7915_pci_remove() | mt7915_sys_recovery_set() mt7915_unregister_device() | mt7915_reset() mt7915_coredump_unregister() | queue_work() vfree(dev->coredump.crash_data) | mt7915_mac_dump_work() | crash_data-> // UAF Fix this by ensuring dump_work is properly canceled before the crash_data is deallocated. Add cancel_work_sync() in mt7915_unregister_device() to synchronize with any pending or executing dump work. | ||||
| CVE-2026-53010 | 1 Linux | 1 Linux Kernel | 2026-09-14 | 9.8 Critical |
| In the Linux kernel, the following vulnerability has been resolved: ksmbd: fix use-after-free in smb2_open during durable reconnect In smb2_open, the call to ksmbd_put_durable_fd(fp) drops the reference to the durable file descriptor early during the durable reconnect process. If an error occurs subsequently (eg, ksmbd_iov_pin_rsp fails) or a scavenger accesses the file, it leads to a use-after-free when accessing fp properties (eg fp->create_time). Move the single put to the end of the function below err_out2 so fp stays valid until smb2_open returns. | ||||

| CVE-2024-35887 | 1 Linux | 1 Linux Kernel | 2026-09-14 | 8.8 High |
| In the Linux kernel, the following vulnerability has been resolved: ax25: fix use-after-free bugs caused by ax25_ds_del_timer When the ax25 device is detaching, the ax25_dev_device_down() calls ax25_ds_del_timer() to cleanup the slave_timer. When the timer handler is running, the ax25_ds_del_timer() that calls del_timer() in it will return directly. As a result, the use-after-free bugs could happen, one of the scenarios is shown below: (Thread 1) | (Thread 2) | ax25_ds_timeout() ax25_dev_device_down() | ax25_ds_del_timer() | del_timer() | ax25_dev_put() //FREE | | ax25_dev-> //USE In order to mitigate bugs, when the device is detaching, use timer_shutdown_sync() to stop the timer. | ||||

| CVE-2026-80229 | 2 Curl, Haxx | 2 Curl, Curl | 2026-09-11 | 7.5 High |
| When performing transfers via libcurl’s multi interface, pooled TLS connections can outlive their originating easy handles. In OpenSSL 3 provider configurations, libcurl attaches an allocated library context to the easy handle's state and passes it to OpenSSL without acquiring an ownership reference; destroying the easy handle prematurely frees this context while the active connection retains a dangling pointer, leading to a heap-use-after-free upon subsequent I/O or post-handshake operations. | ||||
