Astra Linux – Vulnerability in Linux 5.10, Linux

In the Linux kernel, the following vulnerabilities have been resolved: Bluetooth: L2CAP: Fix for u8 overflow By continuously sending L2CAPCONFREQ packets, chan-numconfrsp increases multiple times, eventually exceeding the maximum number i.e., 255. This patch prevents this issue by adding a bounda...

CVE-2026-43134 Bluetooth: L2CAP: Fix missing key size check for L2CAP_LE_CONN_REQ

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: L2CAP: Fix missing key size check for L2CAPLECONNREQ This adds a check for encryption key size upon receiving L2CAPLECONNREQ which is required by L2CAP/LE/CFC/BV-15-C which expects L2CAPCRLEBADKEYSIZE...

CVE-2026-23462

A flaw was found in the Linux kernel's Bluetooth subsystem HIDP. A local attacker can exploit a use-after-free vulnerability by failing to properly drop a reference to an L2CAP Logical Link Control and Adaptation Protocol connection during a user removal callback. This memory corruption flaw may...

SUSE CVE-2026-23395

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: L2CAP: Fix accepting multiple L2CAPECREDCONNREQ Currently the code attempts to accept requests regardless of the command identifier which may cause multiple requests to be marked as pending FLAGDEFERSETUP which can cau...
