It was found that all variables in the jffs_inode_info\nstructure were 5a5a5a5a, except for the first member sem. It is suspected that these\nvariables are not initialized because they were set to 5a5a5a5a during memory testing,\nwhich is meant to detect uninitialized memory.The sem variable is initialized in the\nfunction jffs2_i_init_once, while other members are initialized in\nthe function jffs2_init_inode_info.\n\nThe function jffs2_init_inode_info is called after iget_locked,\nbut in the iget_locked function, the destroy_inode process is triggered,\nwhich releases the inode and consequently, the target member of the inode\nis not initialized.In concurrent high pressure scenarios, iget_locked\nmay enter the destroy_inode branch as described in the code.\n\nSince the destroy_inode functionality of jffs2 only releases the target,\nthe fix method is to set target to NULL in jffs2_i_init_once.","state":"PUBLISHED","assigner":"Linux","published_at":"2024-07-30 08:15:03","updated_at":"2026-08-04

It was found that all variables in the jffs_inode_info\nstructure were 5a5a5a5a, except for the first member sem. It is suspected that these\nvariables are not initialized because they were set to 5a5a5a5a during memory testing,\nwhich is meant to detect uninitialized memory.The sem variable is initialized in the\nfunction jffs2_i_init_once, while other members are initialized in\nthe function jffs2_init_inode_info.\n\nThe function jffs2_init_inode_info is called after iget_locked,\nbut in the iget_locked function, the destroy_inode process is triggered,\nwhich releases the inode and consequently, the target member of the inode\nis not initialized.In concurrent high pressure scenarios, iget_locked\nmay enter the destroy_inode branch as described in the code.\n\nSince the destroy_inode functionality of jffs2 only releases the target,\nthe fix method is to set target to NULL in jffs2_i_init_once."}],"metrics":[{"cvssV3_1":{"baseScore":7.8,"baseSeverity":"HIGH","vectorString":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"}}],"providerMetadata":{"dateUpdated":"2026-08-04T09:28:52.369Z","orgId":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","shortName":"Linux"},"references":[{"url":"https://git.kernel.org/stable/c/b6c8b3e31eb88c85094d848a0bd8b4bafe67e4d8"},{"url":"https://git.kernel.org/stable/c/0b3246052e01e61a55bb3a15b76acb006759fe67"},{"url":"https://git.kernel.org/stable/c/6d6d94287f6365282bbf41e9a5b5281985970789"},{"url":"https://git.kernel.org/stable/c/5ca26334fc8a3711fed14db7f9eb1c621be4df65"},{"url":"https://git.kernel.org/stable/c/751987a5d8ead0cc405fad96e83ebbaa51c82dbc"},{"url":"https://git.kernel.org/stable/c/d0bbbf31462a400bef4df33e22de91864f475455"},{"url":"https://git.kernel.org/stable/c/05fc1ef892f862c1197b11b288bc00f602d2df0c"},{"url":"https://git.kernel.org/stable/c/af9a8730ddb6a4b2edd779ccc0aceb994d616830"}],"title":"jffs2:

of\nthe jffs_inode_info structure. It was found that all variables in the jffs_inode_info\nstructure were 5a5a5a5a, except for the first member sem. It is suspected that these\nvariables are not initialized because they were set to 5a5a5a5a during memory testing,\nwhich is meant to detect uninitialized memory.The sem variable is initialized in the\nfunction jffs2_i_init_once, while other members are initialized in\nthe function jffs2_init_inode_info.\n\nThe function jffs2_init_inode_info is called after iget_locked,\nbut in the iget_locked function, the destroy_inode process is triggered,\nwhich releases the inode and consequently, the target member of the inode\nis not initialized.In concurrent high pressure scenarios, iget_locked\nmay enter the destroy_inode branch as described in the code.\n\nSince the destroy_inode functionality of jffs2 only releases the target,\nthe fix method is to set target to NULL in jffs2_i_init_once.","Type":"Description","Title":"jffs2: Fix potential illegal address access in jffs2_free_inode"}]}}}
