SUSE CVE-2011-4080

The sysrqsysctlhandler function in kernel/sysctl.c in the Linux kernel before 2.6.39 does not require the CAPSYSADMIN capability to modify the dmesgrestrict value, which allows local users to bypass intended access restrictions and read the kernel ring buffer by leveraging root privileges, as...

SUSE CVE-2016-2841

The ne2000receive function in the NE2000 NIC emulation support hw/net/ne2000.c in QEMU before 2.5.1 allows local guest OS administrators to cause a denial of service infinite loop and QEMU process crash via crafted values for the PSTART and PSTOP registers, involving ring buffer control...

SUSE CVE-2016-9754

SUSE CVE-2020-27825

A use-after-free flaw was found in kernel/trace/ringbuffer.c in Linux kernel before 5.10-rc1. There was a race problem in traceopen and resize of cpu buffer running parallely on different cpus, may cause a denial of service problem DOS. This flaw could even allow a local attacker with special use...

SUSE CVE-2021-3489

The eBPF RINGBUF bpfringbufreserve function in the Linux kernel did not check that the allocated size was smaller than the ringbuf size, allowing an attacker to perform out-of-bounds writes within the kernel and therefore, arbitrary code execution. This issue was fixed via commit 4b81ccebaeee "bp...
