| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 2024-05-01 | CVE-2024-27043 | Use After Free vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: media: edia: dvbdev: fix a use-after-free In dvb_register_device, *pdvbdev is set equal to dvbdev, which is freed in several error-handling paths. | 7.8 |
| 2024-05-01 | CVE-2024-27051 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: cpufreq: brcmstb-avs-cpufreq: add check for cpufreq_cpu_get's return value cpufreq_cpu_get may return NULL. | 5.5 |
| 2024-05-01 | CVE-2024-27074 | Memory Leak vulnerability in multiple products In the Linux kernel, the following vulnerability has been resolved: media: go7007: fix a memleak in go7007_load_encoder In go7007_load_encoder, bounce(i.e. | 5.5 |
| 2024-05-01 | CVE-2024-27078 | Memory Leak vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: media: v4l2-tpg: fix some memleaks in tpg_alloc In tpg_alloc, resources should be deallocated in each and every error-handling paths, since they are allocated in for statements. Otherwise there would be memleaks because tpg_free is called only when tpg_alloc return 0. | 5.5 |
| 2024-05-01 | CVE-2024-26930 | Double Free vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: scsi: qla2xxx: Fix double free of the ha->vp_map pointer Coverity scan reported potential risk of double free of the pointer ha->vp_map. | 7.8 |
| 2024-05-01 | CVE-2024-26933 | Improper Locking vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: USB: core: Fix deadlock in port "disable" sysfs attribute The show and store callback routines for the "disable" sysfs attribute file in port.c acquire the device lock for the port's parent hub device. | 7.8 |
| 2024-05-01 | CVE-2024-26934 | Improper Locking vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: USB: core: Fix deadlock in usb_deauthorize_interface() Among the attribute file callback routines in drivers/usb/core/sysfs.c, the interface_authorized_store() function is the only one which acquires a device lock on an ancestor device: It calls usb_deauthorize_interface(), which locks the interface's parent USB device. The will lead to deadlock if another process already owns that lock and tries to remove the interface, whether through a configuration change or because the device has been disconnected. | 7.8 |
| 2024-05-01 | CVE-2024-26949 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu/pm: Fix NULL pointer dereference when get power limit Because powerplay_table initialization is skipped under sriov case, We check and set default lower and upper OD value if powerplay_table is NULL. | 5.5 |
| 2024-05-01 | CVE-2024-26952 | Classic Buffer Overflow vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: ksmbd: fix potencial out-of-bounds when buffer offset is invalid I found potencial out-of-bounds when buffer offset fields of a few requests is invalid. | 7.8 |
| 2024-05-01 | CVE-2024-26958 | Use After Free vulnerability in multiple products In the Linux kernel, the following vulnerability has been resolved: nfs: fix UAF in direct writes In production we have been hitting the following warning consistently ------------[ cut here ]------------ refcount_t: underflow; use-after-free. WARNING: CPU: 17 PID: 1800359 at lib/refcount.c:28 refcount_warn_saturate+0x9c/0xe0 Workqueue: nfsiod nfs_direct_write_schedule_work [nfs] RIP: 0010:refcount_warn_saturate+0x9c/0xe0 PKRU: 55555554 Call Trace: <TASK> ? __warn+0x9f/0x130 ? refcount_warn_saturate+0x9c/0xe0 ? report_bug+0xcc/0x150 ? handle_bug+0x3d/0x70 ? exc_invalid_op+0x16/0x40 ? asm_exc_invalid_op+0x16/0x20 ? refcount_warn_saturate+0x9c/0xe0 nfs_direct_write_schedule_work+0x237/0x250 [nfs] process_one_work+0x12f/0x4a0 worker_thread+0x14e/0x3b0 ? ZSTD_getCParams_internal+0x220/0x220 kthread+0xdc/0x120 ? __btf_name_valid+0xa0/0xa0 ret_from_fork+0x1f/0x30 This is because we're completing the nfs_direct_request twice in a row. The source of this is when we have our commit requests to submit, we process them and send them off, and then in the completion path for the commit requests we have if (nfs_commit_end(cinfo.mds)) nfs_direct_write_complete(dreq); However since we're submitting asynchronous requests we sometimes have one that completes before we submit the next one, so we end up calling complete on the nfs_direct_request twice. The only other place we use nfs_generic_commit_list() is in __nfs_commit_inode, which wraps this call in a nfs_commit_begin(); nfs_commit_end(); Which is a common pattern for this style of completion handling, one that is also repeated in the direct code with get_dreq()/put_dreq() calls around where we process events as well as in the completion paths. Fix this by using the same pattern for the commit requests. Before with my 200 node rocksdb stress running this warning would pop every 10ish minutes. | 7.8 |
