Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: netfs: Fixed a race condition between cache write completion and the setting of ALLQUEUED. When netfslib issues subrequests, these subrequests start processing immediately and may complete before we reach the end of the issuing...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: netfs: The “copy-to-cache” mechanism has been fixed so that it performs collection using Ceph+FSCache. The “copy-to-cache” mechanism used by Ceph with local caching creates a new request to write data that was just read from the...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: RISCV: Misaligned – Restricts user access to kernel memory. The rawcopyto,fromuser function does not call accessok, allowing userspace to access any virtual memory address...

Astra Linux – Vulnerability found in Linux 5.15, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: sparc: Fixed inaccurate exception reporting in copyfromtouser for UltraSPARC III. Anthony Yznaga discovered that a bug in the ext4 code, where large amounts of data were allowed, resulted from copyfromuser returning impossibly...

Astra Linux – Vulnerability found in Linux 5.15, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: sparc: fixed inaccurate exception reporting in copyfromtouser for UltraSPARC. The referenced commit introduced exception handlers for user-space memory references in copyfromuser and copytouser. These handlers return from the...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: ALSA: Timer – Do not take registermutex with copyfrom/touser. The infamous mmaplock taken during copyfrom/touser can often be problematic when it is called within another mutex, as this may lead to deadlocks. In the case of ALSA...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, and Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: usb: xhci: Error handling was added in xhcimapurbfordma. Currently, xhcimapurbfordma creates a temporary buffer and copies the SG list to the new linear buffer. However, if kzallocnode fails, the call to sgpcopytobuffer may lead ...
