CVE-2026-74511

A flaw was found in the Linux kernel's Bluetooth management component. A race condition exists during Extended Inquiry Response EIR updates when the MGMTOPSETLOCALNAME operation is processed concurrently with modifications to the UUID list. This can lead to a use-after-free vulnerability in the...

CVE-2026-74538

A flaw was found in the Linux kernel's Bluetooth ISO Isochronous Stream subsystem. A missing lock when accessing socket connection information within the isoconnectind function could lead to a null pointer dereference. This vulnerability could allow a local attacker to cause a system crash,...

CVE-2026-74529

A flaw was found in the Linux kernel's Bluetooth Host Controller Interface HCI synchronization component. This vulnerability, a Use-After-Free UAF, occurs when a connection object is prematurely released while the hcisync task is still active. A local attacker could potentially exploit this to...

CVE-2026-74508

A flaw was found in the Linux kernel's Bluetooth Human Interface Device Protocol HIDP implementation. A connected HIDP peer can send specially crafted Bluetooth packets that cause the system to read uninitialized memory. This can lead to a denial of service by terminating the HIDP session...

CVE-2026-74528

A flaw was found in the Linux kernel's Bluetooth subsystem. This vulnerability, a use-after-free, occurs when the hcisync component improperly handles connection references, leading to the potential reuse and access of freed memory pointers. A remote attacker could exploit this to cause system...
