In the Linux kernel, the following vulnerability has been resolved: dmaengine: idxd: fix wq size store permission state WQ size can only be changed when the device is disabled. Current code allows change when device is enabled but wq is disabled. Change the check to detect device state. https://git.kernel.org/stable/c/05b7791c4c4aa8304368fdc55ae911f6b34e7281 https://git.kernel.org/stable/c/0fff71c5a311e1264988179f7dcc217fda15fadd https://git.kernel.org/stable/c/4ecf25595273203010bc8318c4aee60ad64037ae
Created kernel tracking bugs for this issue: Affects: fedora-all [bug 2266399]
This was fixed for Fedora with the 5.11.16 stable kernel updates.
The result of automatic check (that is developed by Alexander Larkin) for this CVE-2021-46919 is: CHECK Maybe valid. Check manually. with impact LOW (that is an approximation based on flags SIMPLEFIX IMPROVEONLY ; these flags parsed automatically based on patch data). Such automatic check happens only for Low/Moderates (and only when not from reporter, but parsing already existing CVE). Highs always checked manually (I check it myself and then we check it again in Remediation team). In rare cases some of the Moderates could be increased to High later.
