This may cause a\nsituation where, after a wake-up, the bit-clearing operation hasn't been\ndetected yet, leading to an indefinite wait. The triggering process is as\nfollows:\n[cookie1] [cookie2] [volume_work]\nfscache_perform_lookup\nfscache_create_volume\nfscache_perform_lookup\nfscache_create_volume\nfscache_create_volume_work\ncachefiles_acquire_volume\nclear_and_wake_up_bit\ntest_and_set_bit\ntest_and_set_bit\ngoto maybe_wait\ngoto no_wait\nIn the above process, cookie1 and cookie2 has the same volume. When cookie1\nenters the -no_wait- process, it will clear the bit and wake up the waiting\nprocess. If a barrier is missing, it may cause cookie2 to remain in the\n-wait- process indefinitely.\nIn commit 3288666c7256 (\"fscache: Use clear_and_wake_up_bit() in\nfscache_create_volume_work()\"), barriers were added to similar operations\nin fscache_create_volume_work(), but fscache_create_volume() was missed.\nBy combining the clear and wake operations into clear_and_wake_up_bit() to\nfix this issue."], "name": "CVE-2024-56755", "package_state": [{"cpe": "cpe:/o:redhat:enterprise_linux:6", "fix_state": "Not affected", "package_name": "kernel", "product_name": "Red Hat Enterprise Linux 6"}, {"cpe": "cpe:/o:redhat:enterprise_linux:7", "fix_state": "Not affected", "package_name": "kernel", "product_name": "Red Hat Enterprise Linux 7"}, {"cpe": "cpe:/o:redhat:enterprise_linux:7", "fix_state": "Not affected", "package_name": "kernel-rt", "product_name": "Red Hat Enterprise Linux 7"}, {"cpe": "cpe:/o:redhat:enterprise_linux:8", "fix_state": "Not affected", "package_name": "kernel", "product_name": "Red Hat Enterprise Linux 8"}, {"cpe": "cpe:/o:redhat:enterprise_linux:8", "fix_state": "Not affected", "package_name": "kernel-rt", "product_name": "Red Hat Enterprise Linux 8"}, {"cpe": "cpe:/o:redhat:enterprise_linux:9", "fix_state": "Not affected", "package_name": "kernel", "product_name": "Red Hat Enterprise Linux 9"}, {"cpe": "cpe:/o:redhat:enterprise_linux:9", "fix_state": "Not affected", "package_name": "kernel-rt", "product_name": "Red Hat Enterprise Linux 9"}], "public_date": "2024-12-29T00:00:00Z", "references": ["https://www.cve.org/CVERecord?id=CVE-2024-56755\nhttps://nvd.nist.gov/vuln/detail/CVE-2024-56755\nhttps://lore.kernel.org/linux-cve-announce/2024122928-CVE-2024-56755-b189@gregkh/T"], "threat_severity": "Moderate"}
