Astra Linux – Vulnerability in Linux 5.10, Linux, Linux 5.15

In the Linux kernel, the following vulnerabilities have been resolved: Thermal: Intel: quarkdts: fixed error pointer dereference. If allocsocdts fails, we can simply return. Trying to free “socdts” will result in a Oops error...

Astra Linux – Vulnerabilities in Linux, Linux-5.10, Linux-5.15, Linux-6.1

In the Linux kernel, the following vulnerability has been resolved: drm/komeda: check for error-valued pointer komedapipelinegetstate may return an error-valued pointer; therefore, it is necessary to check that the pointer has a negative or null value before dereferencing it...

Astra Linux – Vulnerabilities in Linux, Linux-5.10, Linux-5.15, Linux-6.1

In the Linux kernel, the following vulnerability has been resolved: gtp: fixed a potential NULL pointer dereferencing issue. When sockfdlookup fails, gtpencapenablesocket returns a NULL pointer. However, its callers only check for error pointers, thereby missing the NULL pointer case. This issue...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: octeontx2-pf: Handling of errors when calling otx2mboxgetrsp in otx2flows.c has been improved. A check for the error pointer was added after calling otx2mboxgetrsp...

Astra Linux – Vulnerability found in Linux 6.1, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: drm/sti: avoided potential dereferencing of error pointers in stigdpatomiccheck. The return value of drmatomicgetcrtcstate needs to be checked. This is done to avoid using the error pointer ‘crtcstate’ in case of a failure...

Astra Linux – Vulnerabilities in Linux, Linux-5.10, Linux-5.15, Linux-6.1

In the Linux kernel, the following vulnerability has been resolved: iommusvabinddevice: This function should return either a device handle for binding SVA data, or an ERRPTR value in error cases. Existing drivers idxd and uacce only check the return value using ISERR. This could potentially lead ...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: media: imx-jpeg: Fixed potential error pointer dereferencing in detachpm The issue occurs on the first line: if jpeg-pddevi && !pmruntimesuspendedjpeg-pddevi If jpeg-pddevi is an error pointer, passing it to pmruntimesuspended wi...

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: net/mlx5: Errors are now handled in mlx5chainscreatetable. In mlx5chainscreatetable, the return values of mlx5getfdbsubns and mlx5getflownamespace must be checked to prevent NULL pointer dereferences. If either function fails, th...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: phy: qcom-qmp-usb: Fix an NULL vs ISERR bug The qmpusbiomap helper function currently returns the raw result of devmioremap for non-exclusive mappings. Since devmioremap may return a NULL pointer, and the caller only checks error...

Astra Linux – Vulnerability in Linux, Linux 5.10

In the Linux kernel before version 5.15.13, the file drivers/net/ethernet/mellanox/mlx5/core/steering/drdomain.c misinterprets the return value of mlx5getuarspage. It expects the return value to be NULL in the error case, but in reality, it is an error pointer...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel before version 6.0.3, the file drivers/gpu/drm/virtio/virtgpuobject.c misinterprets the return value of drmgemshmemgetsgtable. It expects the value to be NULL in the error case, but in reality, it is an error pointer...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: PM / devfreq: mtk-cci: Fixed the potential error pointer dereferencing in the probe function. The drv-sramreg pointer could potentially be set to ERRPTR-EPROBEDEFER, which would lead to an error pointer dereferencing. Use...

Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: clk: clocking-wizard: Fixed an error in clkwzrdregisterdivider. A match was detected for a potential error of dereferencing the pointer in clkwzrdregisterdivider. If devmclkHWRegister fails, it sets “hw” to an error pointer, and...
