Linux kernel security vulnerabilities

Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. A security vulnerability exists in the Linux kernel that stems from a security issue in l2capleflowctlinit in Bluetooth L2CAP...

kernel: integer overflow in l2cap_config_req() in net/bluetooth/l2cap_core.c

An integer overflow flaw was found in the Linux kernel’s L2CAP bluetooth functionality in how a user generates malicious L2CAPCONFREQ packets. This flaw allows a local or bluetooth connection user to crash the system...

kernel: Bluetooth: L2CAP: Fix u8 overflow

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: L2CAP: Fix u8 overflow By keep sending L2CAPCONFREQ packets, chan-numconfrsp increases multiple times and eventually it will wrap around the maximum number i.e., 255. This patch prevents this by adding a boundary check...

SUSE CVE-2024-27399

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: l2cap: fix null-ptr-deref in l2capchantimeout There is a race condition between l2capchantimeout and l2capchandel. When we use l2capchandel to delete the channel, the chan-conn will be set to null. But the conn could b...
