Linux/kernel in versions v5.6-rc1 to v5.12-rc7 is vulnerable to clobbering of SWERR overflow bit on writeback...

The vulnerability of the idxd component in the Linux operating system’s kernel allows a hacker to disclose confidential information.

The vulnerability of the idxd component in the Linux operating system’s kernel is related to the re-writing of the SWERR and OVERFLOW bits. Exploiting this vulnerability can allow an attacker to disclose confidential information...

SUSE CVE-2021-46920

In the Linux kernel, the following vulnerability has been resolved: dmaengine: idxd: Fix clobbering of SWERR overflow bit on writeback Current code blindly writes over the SWERR and the OVERFLOW bits. Write back the bits actually read instead so the driver avoids clobbering the OVERFLOW bit that...

CVE-2021-46920

A flaw was found in the Linux Kernel. The current code blindly writes over the SWERR and OVERFLOW bits. Write back the bits read so that the driver avoids clobbering the OVERFLOW bit that comes after the register is read...
