CVE-2022-50867

CVE-2022-50867 : In the Linux kernel, the drm/msm/a6xx path fixes improper kvzalloc usage vs state_kcalloc. The adreno_show_object() path reallocates the passed data on first call (ascii85-encoded) using kvmalloc/kvfree, so the data must be kvmalloc’d and state_kcalloc cannot be used. The change ...

CVE-2022-50866

CVE-2022-50866 relates to the Linux kernel ASoC: pxa driver, where a null-pointer dereference could occur in the filter() path due to kasprintf() returning NULL when kmalloc() fails. The public fixes require checking the allocation return before using strcmp(), effectively preventing potential cr...

CVE-2023-54207 HID: uclogic: Correct devm device reference for hidinput input_dev name

In the Linux kernel, the following vulnerability has been resolved: HID: uclogic: Correct devm device reference for hidinput inputdev name Reference the HID device rather than the input device for the devm allocation of the inputdev name. Referencing the inputdev would lead to a use-after-free wh...

CVE-2023-54207

CVE-2023-54207 affects the Linux kernel HID: uclogic driver. The root cause is using the input_dev name’s devm allocation instead of referencing the HID device, which could lead to a use-after-free when the input_dev is unregistered and a uevent depending on its name fires. The fix switches to re...
