There is a closely related\nissue which has been fixed:\n\nhttps://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=d6c1b3599b2feb5c7291f5ac3a36e5fa7cedb234\n\n... but, unfortunately, the accepted patch appears to still be\nsusceptible to a null pointer dereference under some interleavings.\n\nTo trigger the bug, we think that `JFS_SBI(ipbmap->i_sb)->bmap` is set\nto NULL in `dbFreeBits` and then dereferenced in `jfs_ioc_trim`. This\nbug manifests quite rarely under normal circumstances, but is\ntriggereable from a syz-program." } ], "affected": [ { "product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected",
