| 2024-09-13 | CVE-2024-46692 | Improper Locking vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: firmware: qcom: scm: Mark get_wq_ctx() as atomic call Currently get_wq_ctx() is wrongly configured as a standard call. | 5.5 |
| 2024-09-13 | CVE-2024-46693 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: soc: qcom: pmic_glink: Fix race during initialization As pointed out by Stephen Boyd it is possible that during initialization of the pmic_glink child drivers, the protection-domain notifiers fires, and the associated work is scheduled, before the client registration returns and as a result the local "client" pointer has been initialized. The outcome of this is a NULL pointer dereference as the "client" pointer is blindly dereferenced. Timeline provided by Stephen: CPU0 CPU1 ---- ---- ucsi->client = NULL; devm_pmic_glink_register_client() client->pdr_notify(client->priv, pg->client_state) pmic_glink_ucsi_pdr_notify() schedule_work(&ucsi->register_work) <schedule away> pmic_glink_ucsi_register() ucsi_register() pmic_glink_ucsi_read_version() pmic_glink_ucsi_read() pmic_glink_ucsi_read() pmic_glink_send(ucsi->client) <client is NULL BAD> ucsi->client = client // Too late! This code is identical across the altmode, battery manager and usci child drivers. Resolve this by splitting the allocation of the "client" object and the registration thereof into two operations. This only happens if the protection domain registry is populated at the time of registration, which by the introduction of commit '1ebcde047c54 ("soc: qcom: add pd-mapper implementation")' became much more likely. | 4.7 |
| 2024-09-13 | CVE-2024-46694 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: avoid using null object of framebuffer Instead of using state->fb->obj[0] directly, get object from framebuffer by calling drm_gem_fb_get_obj() and return error code when object is null to avoid using null object of framebuffer. (cherry picked from commit 73dd0ad9e5dad53766ea3e631303430116f834b3) | 5.5 |
| 2024-09-13 | CVE-2024-46695 | Incorrect Default Permissions vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: selinux,smack: don't bypass permissions check in inode_setsecctx hook Marek Gresko reports that the root user on an NFS client is able to change the security labels on files on an NFS filesystem that is exported with root squashing enabled. The end of the kerneldoc comment for __vfs_setxattr_noperm() states: * This function requires the caller to lock the inode's i_mutex before it * is executed. | 4.4 |
| 2024-09-13 | CVE-2024-46696 | Use After Free vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: nfsd: fix potential UAF in nfsd4_cb_getattr_release Once we drop the delegation reference, the fields embedded in it are no longer safe to access. | 7.8 |
| 2024-09-13 | CVE-2024-46697 | Improper Initialization vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: nfsd: ensure that nfsd4_fattr_args.context is zeroed out If nfsd4_encode_fattr4 ends up doing a "goto out" before we get to checking for the security label, then args.context will be set to uninitialized junk on the stack, which we'll then try to free. Initialize it early. | 5.5 |
| 2024-09-13 | CVE-2024-46698 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: video/aperture: optionally match the device in sysfb_disable() In aperture_remove_conflicting_pci_devices(), we currently only call sysfb_disable() on vga class devices. | 5.5 |
| 2024-09-13 | CVE-2024-46699 | Unspecified vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: drm/v3d: Disable preemption while updating GPU stats We forgot to disable preemption around the write_seqcount_begin/end() pair while updating GPU stats: [ ] WARNING: CPU: 2 PID: 12 at include/linux/seqlock.h:221 __seqprop_assert.isra.0+0x128/0x150 [v3d] [ ] Workqueue: v3d_bin drm_sched_run_job_work [gpu_sched] <...snip...> [ ] Call trace: [ ] __seqprop_assert.isra.0+0x128/0x150 [v3d] [ ] v3d_job_start_stats.isra.0+0x90/0x218 [v3d] [ ] v3d_bin_job_run+0x23c/0x388 [v3d] [ ] drm_sched_run_job_work+0x520/0x6d0 [gpu_sched] [ ] process_one_work+0x62c/0xb48 [ ] worker_thread+0x468/0x5b0 [ ] kthread+0x1c4/0x1e0 [ ] ret_from_fork+0x10/0x20 Fix it. | 7.8 |
| 2024-09-13 | CVE-2024-46700 | Classic Buffer Overflow vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu/mes: fix mes ring buffer overflow wait memory room until enough before writing mes packets to avoid ring buffer overflow. v2: squash in sched_hw_submission fix (cherry picked from commit 34e087e8920e635c62e2ed6a758b0cd27f836d13) | 7.8 |
| 2024-09-11 | CVE-2024-45009 | Unspecified vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: mptcp: pm: only decrement add_addr_accepted for MPJ req Adding the following warning ... WARN_ON_ONCE(msk->pm.add_addr_accepted == 0) ... | 5.5 |
