CVE-2024-58101

Samsung Galaxy Buds and Galaxy Buds 2 audio devices are Bluetooth pairable by default without user input nor a way to stop this mode. As a consequence, audio playback takeover or even microphone recording without user consent or notification is achieved. Note: This is considered a low severity...

CVE-2024-58101

CVE-2024-58101 affects Samsung Galaxy Buds and Galaxy Buds 2. The issue arises because Bluetooth pairing is enabled by default, allowing pairings without user input or an option to disable this mode. Impact described in sources includes potential audio playback takeover and microphone recording w...

kernel: Bluetooth: MGMT: Add error handling to pair_device()

Bluetooth in the Linux kernel does not check for a NULL value, which could lead to dereferencing a null pointed and an eventual crash...

kernel: Bluetooth: btintel: Fix null ptr deref in btintel_read_version

A NULL pointer dereference flaw was found in btintelreadversion in the Linux kernel. This issue may result in a crash...

kernel: Bluetooth: hci_core: Fix not checking skb length on hci_acldata_packet

A use-after-free vulnerability was found in the Linux kernel. The Bluetooth firmware isn't checked if skb contains an ACL header, otherwise the code may attempt to access some uninitialized or invalid memory past the valid skb-data...

kernel: Bluetooth: RFCOMM: avoid leaving dangling sk pointer in rfcomm_sock_alloc()

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: RFCOMM: avoid leaving dangling sk pointer in rfcommsockalloc btsockalloc attaches allocated sk object to the provided sock object. If rfcommdlcalloc fails, we release the sk object, but leave the dangling pointer in th...

kernel: Bluetooth: SCO: Fix not validating setsockopt user input

This CVE pertains to a vulnerability in the Linux kernel's Bluetooth subsystem, specifically within the SCO Synchronous Connection-Oriented protocol. The issue arises from the scosocksetsockopt function, which copies data without properly validating the length of user input. This oversight can le...

kernel: Bluetooth: hci_core: Fix sleeping function called from invalid context

REJECTED CVE A vulnerability was identified in the Linux kernel's Bluetooth: hcicore package, where a sleeping function mutexlock was improperly invoked from an invalid context within the HCI event handling workqueue, potentially leading to kernel warnings or deadlocks. An attacker exploiting thi...

kernel: Bluetooth: Ignore too large handle values in BIG

A vulnerability was found in the Linux kernel's bluetooth subsystem in the function hcilebigsyncestablishedevt where a lack of proper checks does not validate whether a received connection handle exceeds the maximum allowed value. This could lead to system instability or crashes...

kernel: Bluetooth: qca: add missing firmware sanity checks

A flaw was found in the Linux kernel's Bluetooth QCA driver. This vulnerability is caused by missing sanity checks when parsing firmware files before downloading them. A local attacker with low privileges could exploit this to corrupt memory beyond a vmalloced buffer, potentially leading to a...
