https://notcve.org/view.php?id=CVE-2022-48698
In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: fix memory leak when using debugfs_lookup() When calling debugfs_lookup() the result must have dput() called on it, otherwise the memory will leak over time. Fix this up by properly calling dput(). En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: drm/amd/display: soluciona la pérdida de memoria al usar debugfs_lookup() Al llamar a debugfs_lookup(), el resultado debe tener llamado dput(); de lo contrario, la memoria se perderá con el tiempo. Solucione este problema llamando correctamente a dput(). • https://git.kernel.org/stable/c/58acd2ebae034db3bacf38708f508fbd12ae2e54 https://git.kernel.org/stable/c/3a6279d243cb035eaaff1450980b40cf19748f05 https://git.kernel.org/stable/c/cbfac7fa491651c57926c99edeb7495c6c1aeac2 •

https://notcve.org/view.php?id=CVE-2022-48670
In the Linux kernel, the following vulnerability has been resolved: peci: cpu: Fix use-after-free in adev_release() When auxiliary_device_add() returns an error, auxiliary_device_uninit() is called, which causes refcount for device to be decremented and .release callback will be triggered. Because adev_release() re-calls auxiliary_device_uninit(), it will cause use-after-free: [ 1269.455172] WARNING: CPU: 0 PID: 14267 at lib/refcount.c:28 refcount_warn_saturate+0x110/0x15 [ 1269.464007] refcount_t: underflow; use-after-free. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: peci: cpu: corrige use-after-free en adev_release() Cuando auxiliar_device_add() devuelve un error, se llama a auxiliar_device_uninit(), lo que hace que se disminuya el recuento del dispositivo y . Se activará la devolución de llamada de liberación. Debido a que adev_release() vuelve a llamar a auxiliar_device_uninit(), provocará use-after-free: [1269.455172] ADVERTENCIA: CPU: 0 PID: 14267 en lib/refcount.c:28 refcount_warn_saturate+0x110/0x15 [1269.464007] refcount_t: underflow ; use-after-free. • https://git.kernel.org/stable/c/c87f1f99e26ea4ae08cabe753ae98e5626bdba89 https://git.kernel.org/stable/c/1c11289b34ab67ed080bbe0f1855c4938362d9cf • CWE-416: Use After Free •
