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-2024-57885 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-2024-57885/ (Markdown: https://insights.sbomify.com/CVE-2024-57885/index.md)","id":"CVE-2024-57885","markdown":"https://insights.sbomify.com/CVE-2024-57885/index.md","name":"CVE-2024-57885","record":{"aliases":["BELL-CVE-2024-57885","DEBIAN-CVE-2024-57885","GHSA-w665-84fv-4jpv","UBUNTU-CVE-2024-57885"],"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 kernel bug causes a crash when printing kmemleak data under specific real-time and security configurations, leading to denial of service.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":5.5,"severity":"medium","source":"nvd","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-401","name":"Missing Release of Memory after Effective Lifetime"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nmm/kmemleak: fix sleeping function called from invalid context at print message\n\nAddress a bug in the kernel that triggers a \"sleeping function called from\ninvalid context\" warning when /sys/kernel/debug/kmemleak is printed under\nspecific conditions:\n- CONFIG_PREEMPT_RT=y\n- Set SELinux as the LSM for the system\n- Set kptr_restrict to 1\n- kmemleak buffer contains at least one item\n\nBUG: sleeping function called from invalid context at kernel/locking/spinlock_rt.c:48\nin_atomic(): 1, irqs_disabled(): 1, non_block: 0, pid: 136, name: cat\npreempt_count: 1, expected: 0\nRCU nest depth: 2, expected: 2\n6 locks held by cat/136:\n #0: ffff32e64bcbf950 (\u0026p-\u003elock){+.+.}-{3:3}, at: seq_read_iter+0xb8/0xe30\n #1: ffffafe6aaa9dea0 (scan_mutex){+.+.}-{3:3}, at: kmemleak_seq_start+0x34/0x128\n #3: ffff32e6546b1cd0 (\u0026object-\u003elock){....}-{2:2}, at: kmemleak_seq_show+0x3c/0x1e0\n #4: ffffafe6aa8d8560 (rcu_read_lock){....}-{1:2}, at: has_ns_capability_noaudit+0x8/0x1b0\n #5: ffffafe6aabbc0f8 (notif_lock){+.+.}-{2:2}, at: avc_compute_av+0xc4/0x3d0\nirq event stamp: 136660\nhardirqs last  enabled at (136659): [\u003cffffafe6a80fd7a0\u003e] _raw_spin_unlock_irqrestore+0xa8/0xd8\nhardirqs last disabled at (136660): [\u003cffffafe6a80fd85c\u003e] _raw_spin_lock_irqsave+0x8c/0xb0\nsoftirqs last  enabled at (0): [\u003cffffafe6a5d50b28\u003e] copy_process+0x11d8/0x3df8\nsoftirqs last disabled at (0): [\u003c0000000000000000\u003e] 0x0\nPreemption disabled at:\n[\u003cffffafe6a6598a4c\u003e] kmemleak_seq_show+0x3c/0x1e0\nCPU: 1 UID: 0 PID: 136 Comm: cat Tainted: G            E      6.11.0-rt7+ #34\nTainted: [E]=UNSIGNED_MODULE\nHardware name: linux,dummy-virt (DT)\nCall trace:\n dump_backtrace+0xa0/0x128\n show_stack+0x1c/0x30\n dump_stack_lvl+0xe8/0x198\n dump_stack+0x18/0x20\n rt_spin_lock+0x8c/0x1a8\n avc_perm_nonode+0xa0/0x150\n cred_has_capability.isra.0+0x118/0x218\n selinux_capable+0x50/0x80\n security_capable+0x7c/0xd0\n has_ns_capability_noaudit+0x94/0x1b0\n has_capability_noaudit+0x20/0x30\n restricted_pointer+0x21c/0x4b0\n pointer+0x298/0x760\n vsnprintf+0x330/0xf70\n seq_printf+0x178/0x218\n print_unreferenced+0x1a4/0x2d0\n kmemleak_seq_show+0xd0/0x1e0\n seq_read_iter+0x354/0xe30\n seq_read+0x250/0x378\n full_proxy_read+0xd8/0x148\n vfs_read+0x190/0x918\n ksys_read+0xf0/0x1e0\n __arm64_sys_read+0x70/0xa8\n invoke_syscall.constprop.0+0xd4/0x1d8\n el0_svc+0x50/0x158\n el0t_64_sync+0x17c/0x180\n\n%pS and %pK, in the same back trace line, are redundant, and %pS can void\n%pK service in certain contexts.\n\n%pS alone already provides the necessary information, and if it cannot\nresolve the symbol, it falls back to printing the raw address voiding\nthe original intent behind the %pK.\n\nAdditionally, %pK requires a privilege check CAP_SYSLOG enforced through\nthe LSM, which can trigger a \"sleeping function called from invalid\ncontext\" warning under RT_PREEMPT kernels when the check occurs in an\natomic context.
