UBUNTU-CVE-2025-38315

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: btintel: Check dsbr size from EFI variable Since the size of struct btinteldsbr 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...

CVE-2025-38315

CVE-2025-38315 concerns a Linux kernel Bluetooth driver issue (btintel). The root cause is a mismatch between the EFI variable size and the known struct btintel_dsbr size, which could lead to a stack overflow if the EFI variable is larger than expected. The fix alters the check to rely on the kno...

Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: EFI: Do not map the entire mokvar table to determine its size. Currently, when validating the mokvar table, we re-map the entire table on each iteration of the loop, adding space as we discover new entries. If the table grows...
