CVE-2021-47608

CVE-2021-47608 involves a bug in the Linux kernel BPF fetch path (bpf: Fix kernel address leakage in atomic fetch) where a faulty check_mem_access() handling could cause leakage of kernel pointers from spilled stack registers when performing atomic XADD. The issue arises in the BPF_FETCH path, wh...

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 problematic change to the checkmemaccess handling that allows unprivileged users to disclose kernel pointe...

kernel: Information leak in l2cap_parse_conf_req in net/bluetooth/l2cap_core.c

An information leak vulnerability was found in the Linux kernel's implementation of logical link control and adaptation protocol L2CAP, part of the Bluetooth stack in the l2capparseconfreq function. An attacker with physical access within the range of standard Bluetooth transmission could use thi...

SUSE CVE-2018-7755

An issue was discovered in the fdlockedioctl function in drivers/block/floppy.c in the Linux kernel through 4.15.7. The floppy driver will copy a kernel pointer to user memory in response to the FDGETPRM ioctl. An attacker can send the FDGETPRM ioctl and use the obtained kernel pointer to discove...

SUSE CVE-2022-42895

There is an infoleak vulnerability in the Linux kernel's net/bluetooth/l2capcore.c's l2capparseconfreq function which can be used to leak kernel pointers remotely. We recommend upgrading past commit https://github.com/torvalds/linux/commit/b1a2cd50c0357f243b7435a732b4e62ba3157a2e...
