In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: btintel: Check dsbr size from EFI variable
Since the size of struct btintel_dsbr is already known, we can just
start there instead of querying the EFI variable size. If the final
result doesn't match what we expect also fail. This fixes a stack buffer
overflow when the EFI variable is larger than struct btintel_dsbr.

vendor_redhat·2025-07-10·CVSS 5.5
CVE-2025-38315 [MEDIUM] CWE-121 kernel: Bluetooth: btintel: Check dsbr size from EFI variable
kernel: Bluetooth: btintel: Check dsbr size from EFI variable
In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: btintel: Check dsbr size from EFI variable
Since the size of struct btintel_dsbr is already known, we can just
start there instead of querying the EFI variable size. If the final
result doesn't match what we expect also fail. This fixes a stack buffer
overflow when the EFI variable is larger than struct btintel_dsbr.
Statement: In the Intel Bluetooth driver (btintel.c), the function btintel_uefi_get_dsbr() queries a UEFI variable without enforcing a size limit. If the UEFI variable is larger than expected, this leads to a stack buffer overflow when copying data into a fixed-size stack structure. The patch fixes this by initializing data_size to size
