Astra Linux - уязвимость в linux, linux-5.10

It was discovered that there was a lack of CPU resources in the Linux kernel tracing module functionality in versions prior to 5.14-rc3. This issue occurred due to the way users utilize the trace ring buffer. Only privileged local users with the CAPSYSADMIN capability could exploit this flaw to...

Astra Linux - уязвимость в linux, linux-5.10, linux-5.15, linux-6.1

In the Linux kernel, the following vulnerability has been resolved: Ring Buffer: Do not attempt to read beyond the “commit” boundary. When iterating over the ring buffer while the ring buffer is active, the writer can corrupt the reader. There are mechanisms to detect and handle this issue, but t...

In the Linux kernel, the following vulnerability has been resolved: Tracing: Ring-buffer: A fix was made to check the length of events before using them. Check the length of events before adding them for accessing the next index in rbreaddatabuffer. Since this function is used to validate possibl...

kernel: ring-buffer: Do not trigger WARN_ON() due to a commit_overrun

In the Linux kernel, the following vulnerability has been resolved: ring-buffer: Do not trigger WARNON due to a commitoverrun When reading a memory mapped buffer the reader page is just swapped out with the last page written in the write buffer. If the reader page is the same as the commit buffer...
