The original patch might cause a deadlock; revert it. write remount - writebegin - lockpage --- lock ...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: ALSA: pcm: Disabling bottom softirqs as part of spinlockirq on PREEMPTRT sndpcmgrouplockirq acquires a spinlockt and disables interrupts via spinlockirq. This also implicitly disables the handling of softirqs such as TIMERSOFTIRQ...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: ice: Fixed a race condition during the interface enslavement process. The commit 5dbbbd01cbba83 “ice: Avoiding RTNL lock when recreating auxiliary devices” modifies the process of recreating auxiliary devices. As a result, the...

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: iouring/rw: fixed the omission of the NOWAIT check for ODIRECT write operations. When iouring initiates a write operation, it calls kiocbstartwrite, which triggers the super block rwsem. This prevents any freezes from occurring...
