CVE-2023-53284 drm/msm/dpu: check for null return of devm_kzalloc() in dpu_writeback_init()

In the Linux kernel, the following vulnerability has been resolved: drm/msm/dpu: check for null return of devmkzalloc in dpuwritebackinit Because of the possilble failure of devmkzalloc, dpuwbconn might be NULL and will cause null pointer dereference later. Therefore, it might be better to check ...

CVE-2023-53276

In CVE-2023-53276, the Linux kernel ubifs code leaks memory: fscrypt_setup_filename allocates memory for the tmpfile name, but this memory is not freed after the name is copied into the directory entry inode (ubifs_tmpfile → vfs_tmpfile → path_openat). The kmemleak report shows an unreferenced ob...
