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: Fixed a race condition between readers and resize checks. The reader code in rbgetreaderpage swaps a new reader page into the ring buffer by using cmpxchg on old-list.prev-next to point it to the new page. After that...

CVE-2026-43272

CVE-2026-43272 concerns the Linux kernel ring-buffer component. The root cause is an uninitialized pointer in rb_meta_validate_events(), which can be dereferenced during a reader-page validation failure, potentially causing a system crash or instability. The issue is fixed by initializing orig_he...

CVE-2025-68186

In the Linux kernel, the following vulnerability has been resolved: ring-buffer: Do not warn in ringbuffermapgetreader when reader catches up The function ringbuffermapgetreader is a bit more strict than the other get reader functions, and except for certain situations the rbgetreaderpage should...

CVE-2025-68186

The CVE covers a Linux kernel issue in the ring-buffer code. The vulnerability stems from ring_buffer_map_get_reader() being too strict: when the reader catches up to the writer and there is still data on the reader page, rb_get_reader_page() can return NULL and trigger a warning. The fix ensures...

Specifically, when the reader...

DEBIAN-CVE-2025-38267

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...
