The vulnerability in the kernel/trace/ring_buffer.c component of the Linux operating system allows a hacker to trigger a service failure.

The vulnerability in the kernel/trace/ringbuffer.c component of the Linux operating system is related to the use of memory after it has been freed. Exploiting this vulnerability can allow an attacker to cause a service failure...

CVE-2020-27825: Concurrent Execution using Shared Resource with Improper Synchronization

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...

kernel: double free may be caused by the function allocate_trace_buffer in the file kernel/trace/trace.c

A flaw was found in the allocatetracebuffer in kernel/trace/trace.c in the debug subsystem, when failure to allocate a dynamic percpu area, a resource cleanup is called. The pointer buf-buffer still holds the address and is not set to NULL, which can cause a use-after-free problem, leading to a...

CVE-2019-19768: Use After Free

In the Linux kernel 5.4.0-rc2, there is a use-after-free read in the blkaddtrace function in kernel/trace/blktrace.c which is used to fill out a blkiotrace structure and place it in a per-cpu sub-buffer...

CVE-2019-19072: Missing Release of Memory after Effective Lifetime

A memory leak in the predicateparse function in kernel/trace/traceeventsfilter.c in the Linux kernel through 5.3.11 allows attackers to cause a denial of service memory consumption, aka CID-96c5c6e6a5b6...

CVE-2017-18595: Double Free

CVE-2018-12714: Out-of-bounds Write

An issue was discovered in the Linux kernel through 4.17.2. The filter parsing in kernel/trace/traceeventsfilter.c could be called with no filter, which is an N=0 case when it expected at least one line to have been read, thus making the N-1 index invalid. This allows attackers to cause a denial ...
