CVE-2023-53391
In the Linux kernel, the following vulnerability has been resolved: shmem: use ramfs_kill_sb() for kill_sb method of ramfs-based tmpfs As the ramfs-based tmpfs uses ramfs_init_fs_context() for the init_fs_context method, which allocates fc->s_fs_info,…
Does this matter?
Lower severity and a low EPSS score (0.14%). Track it; it rarely justifies an emergency change on its own.
Description
In the Linux kernel, the following vulnerability has been resolved: shmem: use ramfs_kill_sb() for kill_sb method of ramfs-based tmpfs As the ramfs-based tmpfs uses ramfs_init_fs_context() for the init_fs_context method, which allocates fc->s_fs_info, use ramfs_kill_sb() to free it and avoid a memory leak.
