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: L2CAP: Fix uaf in l2cap_connect

A flaw was found in the Linux kernel's Bluetooth L2CAP Logical Link Control and Adaptation Protocol component. This use-after-free vulnerability in the l2capconnect function could allow a local attacker with administrative privileges to cause a denial of service or potentially execute arbitrary...

kernel: Bluetooth: iso: Fix circular lock in iso_listen_bis

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: iso: Fix circular lock in isolistenbis This fixes the circular locking dependency warning below, by releasing the socket lock before enterning isolistenbis, to avoid any potential deadlock with hdev lock. 75.307983...

kernel: Bluetooth: btmtk: avoid UAF in btmtk_process_coredump

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: btmtk: avoid UAF in btmtkprocesscoredump hcidevcdappend may lead to the release of the skb, so it cannot be accessed once it is called. ================================================================== BUG: KASAN:...

kernel: Bluetooth: iso: Always release hdev at the end of iso_listen_bis

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: iso: Always release hdev at the end of isolistenbis Since hcigetroute holds the device before returning, the hdev should be released with hcidevput at the end of isolistenbis even if the function returns with an error...

kernel: Bluetooth: L2CAP: handle NULL sock pointer in l2cap_sock_alloc

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: L2CAP: handle NULL sock pointer in l2capsockalloc A NULL sock pointer is passed into l2capsockalloc when it is called from l2capsocknewconnectioncb and the error handling paths should also be aware of it. Seemingly a...

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: MGMT: Fix possible crash on mgmtindexremoved If mgmtindexremoved is called while there are commands queued on cmdsync it could lead to crashes like the bellow trace: 0x0000053D: listdelentryvalidorreport+0x98/0xdc...

kernel: Bluetooth: hci_conn: Fix UAF in hci_enhanced_setup_sync

A flaw was found in the Linux kernel's Bluetooth subsystem. When an Asynchronous Connection-Less ACL connection is destroyed while the hcienhancedsetupsync function is processing a command, it can lead to a use-after-free UAF condition. An adjacent attacker could exploit this vulnerability to cau...

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

CVE-2024-35964 is a vulnerability in the Linux kernel’s Bluetooth ISO implementation. It occurs because the setsockopt function does not properly validate the size of user-provided data before copying it into kernel memory. This flaw can lead to buffer overflows, potentially resulting in crashes ...

kernel: Bluetooth: L2CAP: Fix not validating setsockopt user input

CVE-2024-35965 is a vulnerability in the Linux kernel's Bluetooth L2CAP implementation, caused by inadequate input length validation in the setsockopt function. This flaw allows overly large user-provided data to be copied into kernel memory, potentially leading to buffer overflows, system...

kernel: Bluetooth: Fix memory leak in hci_req_sync_complete()

This CVE identifies a memory leak in the Linux kernel's Bluetooth subsystem, specifically within the hcireqsynccomplete function. The issue arises because the function fails to release the previous synchronization request state before assigning a new one, leading to increased memory usage over...
