| 2024-11-19 | CVE-2024-53047 | Improper Locking vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: mptcp: init: protect sched with rcu_read_lock Enabling CONFIG_PROVE_RCU_LIST with its dependence CONFIG_RCU_EXPERT creates this splat when an MPTCP socket is created: ============================= WARNING: suspicious RCU usage 6.12.0-rc2+ #11 Not tainted ----------------------------- net/mptcp/sched.c:44 RCU-list traversed in non-reader section!! other info that might help us debug this: rcu_scheduler_active = 2, debug_locks = 1 no locks held by mptcp_connect/176. stack backtrace: CPU: 0 UID: 0 PID: 176 Comm: mptcp_connect Not tainted 6.12.0-rc2+ #11 Hardware name: Bochs Bochs, BIOS Bochs 01/01/2011 Call Trace: <TASK> dump_stack_lvl (lib/dump_stack.c:123) lockdep_rcu_suspicious (kernel/locking/lockdep.c:6822) mptcp_sched_find (net/mptcp/sched.c:44 (discriminator 7)) mptcp_init_sock (net/mptcp/protocol.c:2867 (discriminator 1)) ? sock_init_data_uid (arch/x86/include/asm/atomic.h:28) inet_create.part.0.constprop.0 (net/ipv4/af_inet.c:386) ? __sock_create (include/linux/rcupdate.h:347 (discriminator 1)) __sock_create (net/socket.c:1576) __sys_socket (net/socket.c:1671) ? __pfx___sys_socket (net/socket.c:1712) ? do_user_addr_fault (arch/x86/mm/fault.c:1419 (discriminator 1)) __x64_sys_socket (net/socket.c:1728) do_syscall_64 (arch/x86/entry/common.c:52 (discriminator 1)) entry_SYSCALL_64_after_hwframe (arch/x86/entry/entry_64.S:130) That's because when the socket is initialised, rcu_read_lock() is not used despite the explicit comment written above the declaration of mptcp_sched_find() in sched.c. | 5.5 |
| 2024-11-19 | CVE-2024-53048 | Unspecified vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: ice: fix crash on probe for DPLL enabled E810 LOM The E810 Lan On Motherboard (LOM) design is vendor specific. | 5.5 |
| 2024-11-19 | CVE-2024-53049 | Unspecified vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: slub/kunit: fix a WARNING due to unwrapped __kmalloc_cache_noprof 'modprobe slub_kunit' will have a warning as shown below. | 5.5 |
| 2024-11-19 | CVE-2024-53050 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: drm/i915/hdcp: Add encoder check in hdcp2_get_capability Add encoder check in intel_hdcp2_get_capability to avoid null pointer error. | 5.5 |
| 2024-11-19 | CVE-2024-53051 | Unspecified vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: drm/i915/hdcp: Add encoder check in intel_hdcp_get_capability Sometimes during hotplug scenario or suspend/resume scenario encoder is not always initialized when intel_hdcp_get_capability add a check to avoid kernel null pointer dereference. | 5.5 |
| 2024-11-19 | CVE-2024-53052 | Improper Locking vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: io_uring/rw: fix missing NOWAIT check for O_DIRECT start write When io_uring starts a write, it'll call kiocb_start_write() to bump the super block rwsem, preventing any freezes from happening while that write is in-flight. | 4.4 |
| 2024-11-19 | CVE-2024-53053 | Improper Locking vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: scsi: ufs: core: Fix another deadlock during RTC update If ufshcd_rtc_work calls ufshcd_rpm_put_sync() and the pm's usage_count is 0, we will enter the runtime suspend callback. | 5.5 |
| 2024-11-19 | CVE-2024-53055 | Infinite Loop vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: wifi: iwlwifi: mvm: fix 6 GHz scan construction If more than 255 colocated APs exist for the set of all APs found during 2.4/5 GHz scanning, then the 6 GHz scan construction will loop forever since the loop variable has type u8, which can never reach the number found when that's bigger than 255, and is stored in a u32 variable. Also move it into the loops to have a smaller scope. Using a u32 there is fine, we limit the number of APs in the scan list and each has a limit on the number of RNR entries due to the frame size. | 5.5 |
| 2024-11-19 | CVE-2024-53056 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: drm/mediatek: Fix potential NULL dereference in mtk_crtc_destroy() In mtk_crtc_create(), if the call to mbox_request_channel() fails then we set the "mtk_crtc->cmdq_client.chan" pointer to NULL. | 5.5 |
| 2024-11-19 | CVE-2024-53057 | Use After Free vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: net/sched: stop qdisc_tree_reduce_backlog on TC_H_ROOT In qdisc_tree_reduce_backlog, Qdiscs with major handle ffff: are assumed to be either root or ingress. | 7.8 |
