UBUNTU-CVE-2026-74528
In the Linux kernel, the following vulnerability has been resolved: Bluetooth: hcisync: hold conn in hcipastsync callback Avoids giving freed pointers to hciconnvalid, which kmalloc may have reused. Hold refcount to avoid that...
UBUNTU-CVE-2026-74532
In the Linux kernel, the following vulnerability has been resolved: Bluetooth: btintel: Validate length before parsing diagnostics TLV btinteldiagnostics accesses tlv-val0 without first validating that the diagnostics VSE is long enough to contain that field, so may cause reading data beyond the...
CVE-2026-74535
In the Linux kernel, the following vulnerability has been resolved: Bluetooth: ISO: avoid deadlocks in isosocktimeout isosocktimeout takes locksock, so sync disabling the timer while holding that lock may deadlock. isosocktimeout may also run concurrently with isoconndel, which leads to UAF Task ...

CVE-2026-74541
CVE-2026-74541 relates to the Linux kernel Bluetooth ISO path. The vulnerability arises when detaching a connection from hcon without clearing conn->hcon->iso_data, leading to a use-after-free in iso_conn_free() and potential UAF unless iso_data is cleared. The fixed sequence clears iso_dat...
