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.
Affected configurations
• linux linux kernel (>= 2.6.30 < 5.10.188)
• linux linux kernel (>= 5.11 < 5.15.121)
• linux linux kernel (>= 5.16 < 6.1.39)
