CVSS: -EPSS: 0%CPEs: 4EXPL: 0CVE-2024-49874 – i3c: master: svc: Fix use after free vulnerability in svc_i3c_master Driver Due to Race Condition
https://notcve.org/view.php?id=CVE-2024-49874
In the Linux kernel, the following vulnerability has been resolved: i3c: master: svc: Fix use after free vulnerability in svc_i3c_master Driver Due to Race Condition In the svc_i3c_master_probe function, &master->hj_work is bound with svc_i3c_master_hj_work, &master->ibi_work is bound with svc_i3c_master_ibi_work. And svc_i3c_master_ibi_work can start the hj_work, svc_i3c_master_irq_handler can start the ibi_work. If we remove the module which will call svc_i3c_master_remove to make cleanup, it will free master->base through i3c_master_unregister while the work mentioned above will be used. The sequence of operations that may lead to a UAF bug is as follows: CPU0 CPU1 | svc_i3c_master_hj_work svc_i3c_master_remove | i3c_master_unregister(&master->base)| device_unregister(&master->dev) | device_release | //free master->base | | i3c_master_do_daa(&master->base) | //use master->base Fix it by ensuring that the work is canceled before proceeding with the cleanup in svc_i3c_master_remove. • https://git.kernel.org/stable/c/0f74f8b6675cc36d689abb4d9b3d75ab4049b7d7 https://git.kernel.org/stable/c/4ac637122930cc4ab7e2c22e364cf3aaf96b05b1 https://git.kernel.org/stable/c/4318998892bf8fe99f97bea18c37ae7b685af75a https://git.kernel.org/stable/c/27b55724d3f781dd6e635e89dc6e2fd78fa81a00 https://git.kernel.org/stable/c/61850725779709369c7e907ae8c7c75dc7cec4f3 •

In the Linux kernel, the following vulnerability has been resolved: mm/filemap: fix filemap_get_folios_contig THP panic Patch series "memfd-pin huge page fixes". Fix multiple bugs that occur when using memfd_pin_folios with hugetlb pages and THP. The hugetlb bugs only bite when the page is not yet faulted in when memfd_pin_folios is called. The THP bug bites when the starting offset passed to memfd_pin_folios is not huge page aligned. See the commit messages for details.

https://notcve.org/view.php?id=CVE-2024-49871
In the Linux kernel, the following vulnerability has been resolved: Input: adp5589-keys - fix NULL pointer dereference We register a devm action to call adp5589_clear_config() and then pass the i2c client as argument so that we can call i2c_get_clientdata() in order to get our device object. However, i2c_set_clientdata() is only being set at the end of the probe function which means that we'll get a NULL pointer dereference in case the probe function fails early. • https://git.kernel.org/stable/c/30df385e35a48f773b85117fc490152c2395e45b https://git.kernel.org/stable/c/4449fedb8a710043fc0925409eba844c192d4337 https://git.kernel.org/stable/c/34e304cc53ae5d3c8e3f08b41dd11e0d4f3e01ed https://git.kernel.org/stable/c/7c3f04223aaf82489472d614c6decee5a1ce8d7f https://git.kernel.org/stable/c/9a38791ee79bd17d225c15a6d1479448be127a59 https://git.kernel.org/stable/c/122b160561f6429701a0559a0f39b0ae309488c6 https://git.kernel.org/stable/c/fb5cc65f973661241e4a2b7390b429aa7b330c69 •
