https://notcve.org/view.php?id=CVE-2024-53088
In the Linux kernel, the following vulnerability has been resolved: i40e: fix race condition by adding filter's intermediate sync state Fix a race condition in the i40e driver that leads to MAC/VLAN filters becoming corrupted and leaking. Address the issue that occurs under heavy load when multiple threads are concurrently modifying MAC/VLAN filters by setting mac and port VLAN. 1. Thread T0 allocates a filter in i40e_add_filter() within i40e_ndo_set_vf_port_vlan(). 2. Thread T1 concurrently frees the filter in __i40e_del_filter() within i40e_ndo_set_vf_mac(). 3. Subsequently, i40e_service_task() calls i40e_sync_vsi_filters(), which refers to the already freed filter memory, causing corruption.

https://notcve.org/view.php?id=CVE-2024-53084
In the Linux kernel, the following vulnerability has been resolved: drm/imagination: Break an object reference loop When remaining resources are being cleaned up on driver close, outstanding VM mappings may result in resources being leaked, due to an object reference loop, as shown below, with each object (or set of objects) referencing the object below it: PVR GEM Object GPU scheduler "finished" fence GPU scheduler “scheduled” fence PVR driver “done” fence PVR Context PVR VM Context PVR VM Mappings PVR GEM Object The reference that the PVR VM Context has on the VM mappings is a soft one, in the sense that the freeing of outstanding VM mappings is done as part of VM context destruction; no reference counts are involved, as is the case for all the other references in the loop. To break the reference loop during cleanup, free the outstanding VM mappings before destroying the PVR Context associated with the VM context. • https://git.kernel.org/stable/c/cb86db12b290ed07d05df00d99fa150bb123e80e https://git.kernel.org/stable/c/b04ce1e718bd55302b52d05d6873e233cb3ec7a1 •

CVSS: -EPSS: %CPEs: 8EXPL: 0CVE-2024-53063 – media: dvbdev: prevent the risk of out of memory access
https://notcve.org/view.php?id=CVE-2024-53063
In the Linux kernel, the following vulnerability has been resolved: media: dvbdev: prevent the risk of out of memory access The dvbdev contains a static variable used to store dvb minors. The behavior of it depends if CONFIG_DVB_DYNAMIC_MINORS is set or not. When not set, dvb_register_device() won't check for boundaries, as it will rely that a previous call to dvb_register_adapter() would already be enforcing it. On a similar way, dvb_device_open() uses the assumption that the register functions already did the needed checks. This can be fragile if some device ends using different calls. This also generate warnings on static check analysers like Coverity. So, add explicit guards to prevent potential risk of OOM issues. • https://git.kernel.org/stable/c/5dd3f3071070f5a306bdf8d474c80062f5691cba https://git.kernel.org/stable/c/fedfde9deb83ac8d2f3d5f36f111023df34b1684 https://git.kernel.org/stable/c/3b88675e18b6517043a6f734eaa8ea6eb3bfa140 https://git.kernel.org/stable/c/a4a17210c03ade1c8d9a9f193a105654b7a05c11 https://git.kernel.org/stable/c/5f76f7df14861e3a560898fa41979ec92424b58f https://git.kernel.org/stable/c/b751a96025275c17f04083cbfe856822f1658946 https://git.kernel.org/stable/c/1e461672616b726f29261ee81bb991528818537c https://git.kernel.org/stable/c/9c17085fabbde2041c893d29599800f2d •
