CVSS: 5.5EPSS: 0%CPEs: 3EXPL: 0CVE-2021-46920 – dmaengine: idxd: Fix clobbering of SWERR overflow bit on writeback
https://notcve.org/view.php?id=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 comes after the register is read. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: dmaengine: idxd: corrige el problema del bit de desbordamiento SWERR en la reescritura El código actual escribe ciegamente sobre los bits SWERR y OVERFLOW. En su lugar, vuelva a escribir los bits realmente leídos para que el controlador evite dañar el bit OVERFLOW que viene después de leer el registro. • https://git.kernel.org/stable/c/bfe1d56091c1a404b3d4ce7e9809d745fc4453bb https://git.kernel.org/stable/c/a5ad12d5d69c63af289a37f05187a0c6fe93553d https://git.kernel.org/stable/c/02981a44a0e402089775416371bd2e0c935685f8 https://git.kernel.org/stable/c/ea941ac294d75d0ace50797aebf0056f6f8f7a7f •

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. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: dmaengine: idxd: corregir el tamaño de wq estado del permiso de almacenamiento El tamaño de WQ solo se puede cambiar cuando el dispositivo está deshabilitado.

https://notcve.org/view.php?id=CVE-2021-46918
In the Linux kernel, the following vulnerability has been resolved: dmaengine: idxd: clear MSIX permission entry on shutdown Add disabling/clearing of MSIX permission entries on device shutdown to mirror the enabling of the MSIX entries on probe. Current code left the MSIX enabled and the pasid entries still programmed at device shutdown. En el kernel de Linux, se resolvió la siguiente vulnerabilidad: dmaengine: idxd: borrar entrada de permiso MSIX al apagar Agregue la desactivación/borrado de entradas de permiso MSIX al apagar el dispositivo para reflejar la habilitación de las entradas MSIX en la sonda. El código actual dejó el MSIX habilitado y las entradas pasivas aún programadas al apagar el dispositivo. • https://git.kernel.org/stable/c/8e50d392652f20616a136165dff516b86baf5e49 https://git.kernel.org/stable/c/c84b8982d7aa9b4717dc36a1c6cbc93ee153b500 https://git.kernel.org/stable/c/6df0e6c57dfc064af330071f372f11aa8c584997 •

In the Linux kernel, the following vulnerability has been resolved: dmaengine: idxd: fix wq cleanup of WQCFG registers A pre-release silicon erratum workaround where wq reset does not clear WQCFG registers was leaked into upstream code. Use wq reset command instead of blasting the MMIO region. This also address an issue where we clobber registers in future devices. En el kernel de Linux, se resolvió la siguiente vulnerabilidad: dmaengine: idxd: corrige la limpieza de wq de los registros WQCFG. Se filtró en el código ascendente un workaround de errata de silicio de prelanzamiento en la que el restablecimiento de wq no borra los registros WQCFG. • https://git.kernel.org/stable/c/da32b28c95a79e399e18c03f8178f41aec9c66e4 https://git.kernel.org/stable/c/2a2df2bd10de44c3804661ed15157817c12d6291 https://git.kernel.org/stable/c/e5eb9757fe4c2392e069246ae78badc573af1833 https://git.kernel.org/stable/c/f7dc8f5619165e1fa3383d0c2519f502d9e2a1a9 https://git.kernel.org/stable/c/ea9aadc06a9f10ad20a90edc0a484f1147d88a7a • CWE-668: Exposure of Resource to Wrong Sphere •
CVSS: 5.5EPSS: 0%CPEs: 2EXPL: 0CVE-2021-46916 – ixgbe: Fix NULL pointer dereference in ethtool loopback test
https://notcve.org/view.php?id=CVE-2021-46916
In the Linux kernel, the following vulnerability has been resolved: ixgbe: Fix NULL pointer dereference in ethtool loopback test The ixgbe driver currently generates a NULL pointer dereference when performing the ethtool loopback test. This is due to the fact that there isn't a q_vector associated with the test ring when it is setup as interrupts are not normally added to the test rings. To address this I have added code that will check for a q_vector before returning a napi_id value. If a q_vector is not present it will return a value of 0. En el kernel de Linux, se resolvió la siguiente vulnerabilidad: ixgbe: corrige la desreferencia de puntero NULL en la prueba de bucle invertido de ethtool. El controlador ixgbe actualmente genera una desreferencia de puntero NULL cuando se realiza la prueba de bucle invertido de ethtool. • https://git.kernel.org/stable/c/b02e5a0ebb172c8276cea3151942aac681f7a4a6 https://git.kernel.org/stable/c/758d19098df4b0bbca9f40d6ae6c82c9c18b9bba https://git.kernel.org/stable/c/31166efb1cee348eb6314e9c0095d84cbeb66b9d • CWE-476: NULL Pointer Dereference •
