It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2024-48875 in the wild and no public exploit code.\n\nAffected product: Linux kernel. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2024-48875/ (Markdown: https://insights.sbomify.com/CVE-2024-48875/index.md)","id":"CVE-2024-48875","markdown":"https://insights.sbomify.com/CVE-2024-48875/index.md","name":"CVE-2024-48875","record":{"aliases":["AZL-56216","AZL-56255","BELL-CVE-2024-48875","DEBIAN-CVE-2024-48875","GHSA-hg9v-mfmx-jx2x","ROOT-OS-DEBIAN-11-CVE-2024-48875","ROOT-OS-DEBIAN-12-CVE-2024-48875","ROOT-OS-UBUNTU-2204-CVE-2024-48875","UBUNTU-CVE-2024-48875"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"Linux kernel","requires_auth":"low_privilege","summary":"A recursive locking bug in the btrfs filesystem can cause a deadlock and system hang during device replacement operations.","user_interaction":"not_required","vuln_class":"race_condition"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":5.5,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-667","name":"Improper Locking"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nbtrfs: don't take dev_replace rwsem on task already holding it\n\nRunning fstests btrfs/011 with MKFS_OPTIONS=\"-O rst\" to force the usage of\nthe RAID stripe-tree, we get the following splat from lockdep:\n\n BTRFS info (device sdd): dev_replace from /dev/sdd (devid 1) to /dev/sdb started\n\n ============================================\n WARNING: possible recursive locking detected\n 6.11.0-rc3-btrfs-for-next #599 Not tainted\n --------------------------------------------\n btrfs/2326 is trying to acquire lock:\n ffff88810f215c98 (\u0026fs_info-\u003edev_replace.rwsem){++++}-{3:3}, at: btrfs_map_block+0x39f/0x2250\n\n but task is already holding lock:\n ffff88810f215c98 (\u0026fs_info-\u003edev_replace.rwsem){++++}-{3:3}, at: btrfs_map_block+0x39f/0x2250\n\n other info that might help us debug this:\n  Possible unsafe locking scenario:\n\n        CPU0\n        ----\n   lock(\u0026fs_info-\u003edev_replace.rwsem);\n   lock(\u0026fs_info-\u003edev_replace.rwsem);\n\n  *** DEADLOCK ***\n\n  May be due to missing lock nesting notation\n\n 1 lock held by btrfs/2326:\n  #0: ffff88810f215c98 (\u0026fs_info-\u003edev_replace.rwsem){++++}-{3:3}, at: btrfs_map_block+0x39f/0x2250\n\n stack backtrace:\n CPU: 1 UID: 0 PID: 2326 Comm: btrfs Not tainted 6.11.0-rc3-btrfs-for-next #599\n Hardware name: Bochs Bochs, BIOS Bochs 01/01/2011\n Call Trace:\n  \u003cTASK\u003e\n  dump_stack_lvl+0x5b/0x80\n  __lock_acquire+0x2798/0x69d0\n  ?
